Solar power banks are a favorite of world travelers, wilderness campers, and anxious mothers alike. This is due to the fact that they provide piece of mind in an era where we are all so reliant on having access to charging stations for the devices that we use on a daily basis.
Solar energy is an excellent method to begin to rely a little less on the electrical grid. Sunlight-powered power banks are the most convenient solution. Going off the grid isn’t always a matter of personal preference; it’s sometimes a matter of survival.
Solar power banks, as opposed to solar chargers, are capable of retaining their charge. When you set them out and expose them to the light, they simply do not charge your electronic gadget. As an alternative, they are intended to serve as a means of storing the charge generated by the sun for use at a later time.
Many solar bank makers, on the other hand, constructed their products so that solar charging is a secondary feature. It can be used to implement and sustain charge, or it can be used only in an emergency situation. When selecting a solar power bank, it is important to keep this in mind as a primary consideration.
6 Best Solar Power Banks
Finding the Best Solar Power Bank for You
Solar power banks are available in a variety of designs and sizes. They are capable of a wide range of tasks.
Some batteries can retain a charge for several weeks, while others are only sufficient for a few charges. Others have the ability to charge all of your devices several times. However, they will not be able to withstand the elements.
Some solar power banks charge relatively quickly when exposed to sunlight. Others can take up to a week to recharge from the sun’s energy.
It’s critical to think about the tools you might employ in the future. Some of these, though, you may be able to live without.
In order to determine what might be the most useful for you, you’ll need to consider the conditions in which you might find yourself using the charger. People who wish to engage in a variety of activities will most likely opt for applications that are significantly different from one another.
Hikers, Backpackers, Campers
A power bank with the most solar charging capacity would be the most appropriate choice if you will have limited access to power outlets and will be using your device to a semi-restricted extent.
At the same time, though, it is critical to select a material that is resistant to the elements. Power banks with a greater number of solar panels have a tendency to be more brittle. Finding a happy medium between being sturdy, weatherproof, and having the capacity to charge will be critical.
“How many charges can I expect to receive from it?” is the most important question here. In most cases, short-term travelers will not be required to rely on the solar charging capability.
That is true even if their final destination is rather far away. The power banks have the advantage of being able to hold several charges. A solar power bank, on the other hand, is more beneficial than a standard power bank.
For the simple reason that putting it out just once or twice during a brief trip for a few hours each time can provide the bank with enough juice to last you for another day. That should be sufficient for most people’s daily needs when using basic gadgets.
Worriers and Preparers
Whether you’re ready for an oncoming natural disaster or the zombie apocalypse, a solar charger should be a staple of any emergency preparedness plan. A solar bank is particularly valuable since it can store electricity. So that you can be prepared for calamity when it strikes, rather than just when the sun comes out after it has already happened.
You might want to look for banks that are good at keeping their charges in check. You’ll have more time to prepare your equipment. Whatever time of day or night you require power, you can rest certain that all you have to do is turn on the power bank. It will be available to use as soon as possible.
People Who Just Can’t Seem to Remember to get Anything on the Charger at Night
You’ll be able to tell whether this is you. You’re most likely leaving the house with a dead phone and a dead power bank all of the time without even noticing it until you’ve arrived at your destination.
This can be particularly problematic for persons who rely on their smartphones for job purposes. Alternatively, if the location you’re visiting does not have a charging station, you should bring a portable charger.
It might seem a little excessive to get a solar power bank for these types of scenarios, but it isn’t. Solar energy, on the other hand, is the energy of the future. Solar energy may be accessed from virtually any location. As a result, it can be a viable alternative for almost everybody.
Look for power banks that are tiny and portable. Then you may just slip it into your pocket on the way out of the building. You can even attach it to the exterior of a bag to charge your phone while you’re on the go.
How We Ranked the Best Solar Power Banks
As we’ve highlighted, for being such small devices, solar power banks can have a lot of variation between devices in many different ways. So in order to develop a list of the best solar power banks, we needed to consider quite a few different factors for choosing the best devices. In our list, we consider:
Amount of Times it can Charge an Average Device
When we talk about “average devices,” we’re referring to the most popular new cellphones on the market. iPhones and Samsung smartphones are examples of such devices.
Phones that are more than a year old may be able to acquire extra charges from the power bank. Larger, more energy-demanding devices, such as tablets, will almost certainly receive less power than smaller devices.
The amount charged can also be affected by external circumstances. Among these is the cable that you are now utilizing. As a result, keep in mind that these figures represent averages under ideal circumstances.
It serves as an excellent comparative reference point, just as it does for some of the other criteria. In general, a solar power bank with a higher average charge would charge more than a solar power bank with a lower average charge. That holds true even if the numbers aren’t exactly correct.
Amount of Time Needed to Fully Charge using Solar Power
The answer is a resounding yes for several of the solar power banks on our shortlist. This is due to the fact that the solar panels are fairly small. The batteries that they are charging, on the other hand, are typically of a very great capacity. As a result, it takes a large amount of energy to charge them completely.
Solar panels are likewise very reliant on their surrounding environment. In addition, it is only possible to provide an average. Solar power banks that receive the most sunlight would charge far faster than solar power banks that are left outside to charge on a gloomy day, according to the Solar Energy Industries Association.
Even a few hours of charge on your solar power bank will frequently provide enough power to recharge your cell phone or other small gadget several times. As a result, don’t be startled by the large quantity.
It is also crucial to know that the solar charging capability on some solar power banks is intended to be used only in emergencies, which is something to keep in mind. It is not designed to be used as a primary source of charging.
As a result, they were not created with the concept of charging from zero in mind. Rather, they are intended to serve as a source of charge maintenance. That should take a lot less time than you think.
This is a bit of a difficult question. It is commonly expressed as milliamperes (mAh). That is an abbreviation for milli Ampere (Ampere is a unit of current, and milli-Ampere is a smaller unit of current) hour, and it is a measure of the amount of charge stored in a device. This unit of charge indicates the amount of charge that a battery is capable of delivering.
The problem is that in order to make any sense of this number, you must first determine how much current is being drawn by the gadget that is being powered by the battery. There are a variety of elements that can influence this. As a result, it is hard to predict how this will play out in the real world.
The larger the mAh, though, the greater the number of charges you should expect the battery to be able to produce in general.
Size and Weight
Power banks are designed to be lightweight and portable. Thus, we measured and weighed each of the solar power banks to ensure that they were all in compliance. In order to avoid the devices becoming excessively heavy or inconvenient as a result of the solar panels and batteries, we took this precaution.
There is some difference among the items in the list. However, most are not significantly larger or heavier than a smartphone in terms of size and weight. As a result, they are easily transportable.
Durability and Resistance to Weather
Solar panels must be installed outside in order to function properly. As a result, this element is quite significant. Solar power banks are a little different from ordinary power banks, which are often found in your solar backpack or purse the majority of the time if they are not being charged by a separate charger.
Backpacking and trekking are two activities in which solar power banks are quite useful, and some solar power banks are designed specifically for these activities to be more weather resistant. Water and dust-proof ratings, as well as included coverings and the materials used in the construction of the power banks, were considered in order to establish their durability as well as their weather resistance.
In addition to all of the fundamental functionality, we took into consideration any additional features that the gadget might have. Solar flashlights and emergency modes are examples of such devices. The power bank function can be expanded in this manner, increasing its utility and value.
If the device has any of these additional functions, we’ll be sure to mention them. We’ll let you know how well they perform when we find out.
Frequently Asked Questions
Can the solar power bank also be charged by a regular power outlet?
Yes. Every solar power bank on our list really recommended that you first totally charge the gadget using a conventional power outlet before using the solar power bank. Then you can only use solar energy when you absolutely need it.
This is due in part to the fact that solar charging will take far longer than charging from an electrical outlet. Many solar power banks are built with solar charging capabilities as a backup function, which is why they are so popular. Alternatively, it can be used to keep the battery charged.
Solar chargers, which are a distinct type of equipment than a solar power bank, are only capable of operating on solar power alone. In contrast to batteries, they do not store energy in the gadget itself.
Instead, they just convert it into electricity to charge your device. As a result, they cannot be powered by a standard electrical socket.
Why does solar charging take so much longer than charging from an outlet?
85 hours of charging time is a significant amount of time. This is especially true when compared to charging via a wall outlet. That should take no more than a couple hours at the most. There are a variety of variables that contribute to this enormous number of people.
For starters, solar energy isn’t nearly as potent as electricity that is drawn straight from the power grid. As a result, the battery will charge at a slower rate.
Second, the charging process can be slowed even further by weather conditions. Cloudy days result in less direct sun energy, which means the charge will be slower.
Once the power bank has been fully charged, it is also vital to assess how many charges it will be capable of providing. The power bank takes 85 hours to charge but can charge your device ten times, which equates to only 8 hours of solar energy every charge it is capable of delivering to you. Overall, it isn’t a terrible situation.
It’s practically impossible to predict how long it will take for a solar-powered item to charge completely from a given point in time. This is due to the influence of environmental factors. As a result, any time will be a calculation of the mean. It will be determined by the expected amount of time that it will take under specific conditions.
It is possible that the process will take longer than anticipated. Depending on how the day is going, it may take less time at other times.
Will it charge my (insert device name here)?
The quick answer is: most likely. The extended answer is a little more difficult to comprehend.
The truth is that it is somewhat dependent on the solar power bank that you choose. All of the banks in this list should be able to charge any cell phone, tablet, or other comparable device. With larger or less conventional devices, the solution can become more complicated.
In theory, everything that can be plugged into a USB port may be charged. However, charging another portable charger with a power bank, for example, has the potential to cause issues depending on how the input/output of each item is configured.
Other goods, such as cameras, should be checked to see whether they can be charged by USB; nonetheless, it is a good idea to double-check the voltage that your camera can handle as well as the output of the power bank in case something goes wrong.
Because of the variety of input possibilities and the relatively low energy output of these devices, larger devices such as laptops and televisions are unlikely to require charging on these gadgets. It is always a good idea to double-check when in doubt. Most power banks come with a basic list of the types of devices that they are compatible with, which may be found on their packaging.
Will the power bank charge my devices slower because it is solar-powered?
Depending on whatever power bank you choose, some of the power banks may even come with connections and the option for quick charging, making them even faster to charge than the ordinary power bank.
Due to the fact that the power banks are actually batteries that are charged either by a wall charger or by solar power, the battery is what is used to charge your device. The fact that the power bank is solar-powered has no effect on your devices’ charging ability; rather, the battery’s capacity and output are what determine how quickly your device will be recharged.
Do the solar panels make the power bank heavy?
Solar power banks are not inherently lightweight, but they are also not very heavy, and the majority of the weight is borne by the battery itself, rather than the solar panels, which are, in truth, fairly insignificant.
According to our research, the average weight of the solar power banks on our list is little more than 1 pound, which is rather standard for the capacity of this charger. Some smaller power banks are available, however the smallest and lightest ones tend to only produce 1-3 charges, rather than the more powerful ones that produce 5-6 or more.
Rankings and Reviews
Our rankings are based on our evaluation of the top all-around solar power banks that we were able to locate. In order to achieve the highest ranking on our list, we considered the following factors: the amount of time it can charge an average device; the amount of time it takes to fully charge using solar power; battery capacity; battery size and weight; and durability and weather resistance.
It’s true that the lower-ranked candidates are more focused on a few variables, but that doesn’t mean that they aren’t exceptional at what they do.
We’ll begin each review by emphasizing some of the device’s characteristics and providing a quick list of benefits and disadvantages in order to provide a concise assessment of the highs and lows of that particular solar power bank. After that, you’ll find a more in-depth review that goes over the features and explains why we ranked it the way we did.

In ideal conditions, it takes approximately 25-30 hours to fully charge the power bank using solar power, and with a full charge, it can charge most cell phones approximately 12 or more times.
The performance of the solar panels and the batteries are what distinguishes this solar power bank, but it should also be noted for its superb design. It comes in a compact case that, when folded up, is roughly the same size as most smartphones (it measures 6.1 inches by 3.4 inches by 1.4 inches, whereas an iPhone X is 5.73 inches by 2.69 inches by 0.31 inch).
With a case constructed of plastic and synthetic leather that is both sturdy and aesthetically beautiful, the case achieves the perfect balance of practicality and pleasing design.
Beyond the water-resistance of the protective shell, the complete gadget has an IP-65 rating, which indicates that it is resistant to water and dust ingress. A grade of 65 indicates that it is resistant to big droplets and sprays of water, as well as brief periods of being entirely submerged in water, but not complete submersion, and that it is completely dust-resistant.
In addition, the case contains two USB ports (allowing you to charge two devices at the same time), each of which have covers to further protect them from dust and water.
The fact that it is the fastest solar charging device on the market means that it is useful for everyone – from hikers without access to electricity who need a portable charger with some extra features because it is so practical – and that it combines efficiency with functionality and thoughtful features makes it useful for every kind of user.
The solar power bank also has a built-in LED flashlight, which is powered by the solar panels as well as the batteries. Strobe, “SOS,” and steady are the three options available, and while this is an optional function, it does make the power bank a more helpful tool for travelers. Not only does it make use of light, but it also uses it.
What do reviewers say?
When it comes to solar charging, almost all of the reviewers agree that this solar power bank much exceeds their expectations. Where they felt previous products were slow or couldn’t hold up to a solar charger instead of a solar power bank, this gadget functioned admirably. They also praise the convenience with which it can be transported from place to place, as well as the high-quality, long-lasting materials from which it is constructed.
One or two reviews commented on the charger’s usefulness when traveling in isolated areas. An individual who lived in the bush for several months made use of it. It was effective for them when their battery banks were insufficient to maintain the charge of their electronic equipment. They also loved the fact that it was waterproof and could be used with a variety of different devices.
Others who are more casual campers, such as weekend campers, have also expressed how valuable it has been to them. One reviewer reported that it lasted four days despite the fact that he charged his phone and vape pen many times.

Basically, reviewers who were searching for a solar power bank for a variety of various applications were all impressed with its performance, durability, and design. They praised many of the features, including the battery, the case, and even the illumination, and expressed a strong desire to put it to further use.
Features & Considerations
The one continuous criticism leveled at this charger was that it is significantly heavier than its physical dimensions would indicate. While someone might take it up assuming it will feel like a smartphone’s weight due of its shape and size, it actually feels more like the weight of a can of beans (or a particularly large battery) rather than the svelte smartphone we’re used to. But even some who were concerned about the weight of the small gadget recognized that the weight was well worth it given the quantity of capabilities that the small device offers.
Despite the fact that the sun charging function on this solar power bank is effective, some users were dissatisfied with how rapidly the solar power bank was recharged while using a conventional wall charger. The charger does not charge at lightning speed, but it does not charge at a slow pace either.
A different device may be a better alternative for people who are searching for a device that is primarily a power bank, with the solar feature serving as an add-on rather than as the primary feature.
Overall, the FEELLE Solar Power Bank excels at solar charging while also being aesthetically pleasing. Its faults are minor in compared to the areas where it excels, and those looking for the greatest all-around solar power bank would be wise to select this one.

- The high points: simple design, durable, good battery capacity and ability to charge devices, easy to hang, waterproof, USB-C quick charge and iSmart quick charge supported
- The low points: larger and heavier than other options, solar charging is very slow, bulky
This solar charger from RavPower meets all of the requirements for a one-solar-panel solar power bank. Because of its high-capacity battery, it can hold as many charges as many other solar power banks, but it has just one solar panel, rather than three or four, as many other solar power banks. Use of the solar-charging option should be considered as a backup plan at all times. If you want to utilize it with the goal of topping off the battery, that is fine. However, if that is plenty for you, then this device is ideal for you.
The RavPower Solar Charger can recharge an ordinary smart phone up to seven times in one day. Smartphones that require less energy to charge in general, on the other hand, will charge more quickly. It can also charge tablets and other larger gadgets three to four times their original capacity.
Although the device will take around 85 hours to charge in direct sunshine, the battery capacity is competitive, and once it is fully charged, it will provide several charges. To fully charge the device in the sun after only a few charges will not require 85 hours, so a few hours in the sun may be sufficient to fully charge the gadget, as long as the battery is not completely depleted.
The RavPower’s built-in case is made of high-quality materials. The maker designed it to be long-lasting and resistant to turbulence.
It is made of a strong rubber compound. It has ribbing on the outside to make it easier to grip. The solar panel is left uncovered, but the edges have been raised to prevent the panel from splitting again in the future. Additionally, it is waterproof and dust proof. It comes with caps to cover the USB ports, both of which are USB-C compatible and allow iSmart quick charge.
On the top edge of the solar power bank, there is a button. It is activated with the push of a button on your computer. It has three different operating modes: strong, SOS, and strobe. It is located at a convenient location just on the edge. As a result, it is the most practical option for use as a flashlight.
What do reviewers say?
Reviewers liked the durability of this solar power bank. They highlighted how well the battery holds a charge.
Some noted that their solar power bank was able to keep its charge for a month or more. Many also mentioned at least one of the features. Those included the flashlight, the clip to hang the power bank or the built-in case as features that they were glad to have.
According to many reviews, the best part about the solar power bank is its high-capacity battery. Reviewers noted that it charged very fast. They explained that it is durable but also bulky.
Some reviewers felt that this battery was a game-changer. They appreciated the built-in hanging ring and how easy it is to attach it to a backpack.
Features & Considerations
There are two distinct points to consider when using this equipment. Because of its size and weight, it is slightly larger and heavier than other similar solar power banks. Additionally, while the battery is quite efficient, the solar charging leaves a lot to be desired, as previously said.
A major concern is the overall size, particularly because it is a single solar panel power bank, which means the battery is far thicker than most others. The power bank’s overall dimensions, including the case, are 7.1 inches by 3.5 inches by 1.2 inches, and it weighs 1.25 pounds, making it the heaviest item on our list. Choosing this solar power bank is an excellent decision if battery size is not an issue; however, if battery size is a significant factor for you, this may not be the solar power bank for you.
An additional point of worry with this charger is its ability to charge from the sun. The business is as forward about the amount of time it will take to charge the device, noting clearly that customers may expect to need 85 hours to charge the device using sunlight, while also emphasizing that this is due in part to the large capacity of the battery. If you’re fine with solar charging serving as a backup or as a way to recharge the battery, then this is an excellent power bank for you to consider.
- Top Feature #1: Very, very durable – completely waterproof, shock proof, dust proof, etc.
- Top Feature #2: Can charge the average device 4+ times
- The high points: durability, two carabiners attached for hanging, quick charging, flashlight
- The low points: relatively low battery capacity and long charging time, heavy, some have trouble with one of the USB ports
OUTEX is an acronym that stands for Outdoor Xtreme Energy, and the durable solar charger developed by OUTEX promises to meet the demand for energy while performing extreme things outside. The long-lasting nature of this solar power bank is one of its most appealing features. It is completed by a respectable battery with adequate sun charging capability.
The power bank has an IP67 rating, which means it is waterproof. This indicates that if you submerge it in water, it should be fine. (Make certain that it is submerged for less than 30 minutes at a depth of less than 3 feet.) In other words, if you drop it in a pool of water or a shallow pond, there should be no damage to the power bank.
It’s also impervious to dust. Despite these good characteristics, you should exercise caution when driving in extremely hot weather.
The solar power bank is protected from the elements by a tough case. This shields it from all of the different ways you could accidentally drop it.
Plastic and rubber are used to construct the case. It has been reinforced along the edges and particularly in the corners to decrease the impact if it is dropped accidentally. It also features ridges on the bottom to aid in providing better grip.
Two carabiners are attached to the power bank as part of the overall design philosophy of making it the best for outdoor use. There are two of them, one at the top and one at the bottom.
You can use them to attach it to the outside of a backpack or other similar bag, for example. The ability to charge for extended lengths of time will be made possible as a result of this.
The ability to leave it out in the open like that, in theory, helps to compensate for the lengthy charging period in the sunlight. In perfect conditions, you might get by on only sunshine for around 70 hours.
When fully charged, the solar power bank should be able to offer four or more charges to an ordinary smartphone. You may use the battery to power the three-mode flashlight that is incorporated into the device (bright, dim and strobe).
It is the ideal power bank for those who enjoy spending time outside and require a solar-powered power bank that will last through the weather. In exchange for the tough build, it foregoes some solar and battery capabilities. So, if that is your number one priority, this is a fantastic fit for you.
What do reviewers say?
Those that reviewed this solar power bank were mostly hikers, backpackers, and other outdoor enthusiasts who were either already involved in those activities or were aspiring to be involved in such activities. Those that were pleased with the product praised it for its long-lasting quality. They were really pleased with the number of charges they were able to obtain as a result of the situation.
One of those travelers used it on a two-week backpacking journey across the United States. This allowed them to charge two phones four times and also charge a Kindle just once with the same battery power.
After returning from a hiking trip, another reviewer had similar sentiments. She did, however, wish that it had been a little lighter and that she had gotten a little more mileage out of it. Other reviewers expressed concern over the weight of the item, despite the fact that it appeared to be solid.
Features & Considerations
As a result of their efforts to make the solar power bank as sturdy and resistant as possible, the designers ended up adding a significant amount of mass to the gadget. The bottom line is that what you get in terms of protection, you also get in terms of weight in mass.
Some backpackers prefer a lighter and slimmer gadget in order to reduce weight, while others believe that durability is essential; therefore, depending on your preferences, this device may or may not be the ideal option for you.
A few users have reported experiencing issues with the USB-C port and speedy charging, which is not uncommon. According to the company, their concerns were resolved rather quickly, but if speedy charging via USB-C is important to you, purchasing a device that is designed specifically for this purpose may be a better option.
Its second drawback is that it does not have the greatest capacity battery or the finest solar charging ability available on the market. Instead of focusing just on absolute functioning, this power bank takes into account environmental elements in order to create a device that is robust and charges well.
- Top Feature #1: Extremely light but still durable
- Top Feature #2: Can charge the average device 4-5 times
- The high points: light, durable, comes with a carabiner to hang on, fast wall charging
- The low points: relatively slow solar panel charge and low battery capacity, covers for USB ports are not very reliable
BEARTWO recognized a market need for a more portable solar power bank and set out to meet that demand. This solar power bank weighs less than half a pound, making it far lighter than any of the other options and one of the lightest on the market. This one is ideal for folks who are concerned about the weight of the other charges.
Despite the fact that this power bank is extremely lightweight, it does not lose much in terms of protection in order to achieve that lightness. It is still completely waterproof up to 3 feet and 30 minutes of submersion, protecting it from any accidents. It is also protected by a silicon case that should be sufficient to withstand minor bumps and falls, if necessary.
The case was created with a triangular slot in one of the corners, as specified by the manufacturer. In addition, it has a carabiner that fits into that slot. You’ll be able to hang it from just about anywhere this way. While camping, BEARTWO recommends that you hang it from your bag. It will be able to gain a small amount of charge during the day because of this.
A basic feature of solar power banks is an LED flashlight, which has three modes: normal, strobe and SOS. The gadget also has a USB charging port. You could use the light as a flashlight to see in the dark if you wanted to. Simply using it as a simple light to see while you’re trying to connect your gadget to the power bank at night is a good usage for it.
The inability of this equipment to be charged through solar energy is its weak point. It will take 85 hours to fully charge under ideal conditions. When not exposed to direct sunshine, it could take much longer.
This device delivers around 4-5 charges for a cell phone, which is insufficient. The amount of time required to charge in order to yield a charge is therefore relatively large.
What do reviewers say?
The lightweight of this specific solar power bank was praised by reviewers. Despite the fact that they were continually pleased with the additional features The carabiner and flashlight were among the tools used in this endeavor.
Concerning the charging capability, users expressed a variety of opinions on the subject. For some, it proved to be more effective than they anticipated in terms of charging. Others were dissatisfied to a great extent.
Home charging via electricity was a popular feature among users. The fact that they could keep it on their dashboards in their cars was also welcomed by them. Consequently, solar energy can be stored indefinitely.
One reviewer was able to fully charge six iPhones at a time, once for each of the devices. As a result, the bank only had half of its original power remaining.
Unhappy with it according to another reviewer. The man complained that it took a long time to charge his phone, and that it used up all three bars of energy on his bank’s charging station.
The product received positive feedback from reviewers who anticipated the solar charging to be a backup feature. While the majority of people believed they had received a solar charger, those who had hoped for something different were dissatisfied with what they had gotten. When it comes to this product, it appears that expectations should be managed carefully.
Features & Considerations
Although this solar power bank touts itself as being waterproof, one of the ways in which it achieves this certification is by including little rubber covers over the USB ports to ensure that water does not get into the ports themselves. The difficulty with this is that if the USB covers do not remain in place very effectively, the waterproof quality of the gadget may be compromised.
As a result, some users have claimed that the small rubber coverings on their solar power bank did not remain in place very well, making it crucial to remember that this device may not be totally water resistant.
Another thing to keep in mind about this device is that it is not the most efficient in terms of solar charging or battery capacity, which is a drawback. Its battery is actually rather small, and the solar panel is also fairly small, so they both don’t produce as much as other, larger items, but if size is the most important consideration, it remains a practical and dependable power bank.
