What to Look for in a Solar Backpack

Picking a backpack for daily use is already a difficult decision. When deciding on the right solar power backpack, it’s important to consider how and why you’ll be using your bag. While there are a variety of factors at play, from cargo load to charging capabilities, these are the most important variables to consider before purchasing.

What will you be using your solar backpack for?

There are a variety of uses for solar backpacks, and one size does not necessarily fit all. Based on your use, this may determine the wattage of the solar panel, the size of the bag, the material and design of the bag and the extra features.

The most common uses:

  • Commuting to work
  • Traveling abroad
  • Hiking or camping
  • Emergency preparedness
  • Students in college
  • Professional photography


A lightweight bag with a low-wattage solar panel and anti-theft protection is ideal for folks who use their bags to commute to work, travel around unfamiliar cities, or transport books to and from class.

Weatherproofing is preferable but not required, and interior device compartments are a convenient feature.

It is critical for professional photographers and digital nomads to have ample storage space for their equipment. A clamshell bag design is ideal for this, and anti-theft protection can provide an additional layer of security while transporting expensive equipment.shell bag design In order to charge numerous devices at the same time, you’ll also need a high-wattage solar panel.

A robust bag with weatherproofing and a detachable high-wattage solar panel is ideal for individuals who want to walk, camp, or prepare for an emergency situation. The quality of the building, as well as the quality of the solar panel, is critical because you cannot afford for it to malfunction. In this instance, it is preferable to spend more money on a higher-end model.

What are you planning on charging?

The majority of buyers are only interested in charging tiny devices such as cellphones or iPods. In full sun, any backpack with a solar panel with a power output greater than 5 watts can support tiny electronics.

Due to the fact that it takes a few hours longer to charge in cloudy conditions, an additional battery bank is required for power storage when the light is poor. Some backpacks are fitted with battery banks, however others are not, and this may be a significant consideration when selecting a bag for your needs.

Using high-capacity gadgets, such as laptops, will require more power than normal charging methods can provide. A 10W solar panel is sufficient to charge a laptop, albeit it will take many hours to complete the task. Because they do not charge via USB, these types of devices also necessitate the use of adapters and power banks.

The majority of backpacks are not designed to hold a fully charged laptop and are instead designed to hold smaller gadgets. A few kinds and brands are available that can support such power-hungry equipment, but they will cost upwards of $200 to purchase.

Here’s a list of common devices you can charge with a solar backpack:

  • Smartphone
  • Tablet
  • MP3 player
  • Drone
  • GPS device
  • Bluetooth speaker
  • Laptop
  • Camera

Will you be doing physical outdoor activities with your backpack?

Extra features like as suspension systems, hydration bladders, and waterproof textiles may be required depending on the nature of your activity. Size may also be a consideration, since having too much additional room can make you feel weighed down and uneasy. For specialized applications, there are a range of choices available on the market, but in some circumstances, a regular backpack constructed of robust materials may suffice.

A tiny daypack is the best solution for people who engage in extremely intense sports such as jogging or cycling. These bags are lightweight, constructed of breathable mesh, and designed to be worn close to the body for maximum comfort. Some of them are also equipped with hydration bladders and waterproofing, which is an added bonus.

In order to protect your electronic equipment from the elements while trekking or camping across long distances, you’ll need a large bag with plenty of space. This may include water-resistant materials or rain coverings that are built in. Detachable solar panels are also advantageous since they can be tucked away when they are in risk of being damaged, or they may be left out in the sun at camp to charge while you are away from home.

How big of a backpack do you need?

The volume of a backpack is usually measured in liters (L). This specifies the maximum volume of the bag, or the amount of material that can be reasonably packed into the bag before it ruptures. Some firms determine the price depending on the number of additional side pouches or compartments, while others calculate the price based on the bag’s dimensions.

According to general consensus, a “typical” backpack has a capacity of between 15 and 25 liters. This is sufficient space for a laptop computer, a few books, a water bottle, a few changes of clothing, and other random goods to be transported. Generally speaking, most customers favor this mid-range size because it is not too big for daily usage and has the capacity to carry all of their daily necessities.

Smaller “daypacks” are typically 8-10 liters in volume and are only capable of carrying light loads of a few pounds or less. Sporting events, particularly cycling events, and short hiking expeditions are excellent candidates for this. Long-distance hiking backpacks, on the other hand, have a capacity of 30 to 100 liters and may accommodate a substantial quantity of equipment, such as camping supplies. In order to hike for more than a few days, you’ll need a minimum of 60 liters of water per person.

Selection Criteria: How We Ranked the Best Solar Backpacks

Based on our specified criteria, we’ve narrowed down a competitive list of options to feature the 6 best solar backpacks.

Our rankings specifically focus on the power of the solar panel, the size of the backpack and the overall quality of design. It also takes into consideration the unique use of the bag depending on the buyer’s intentions.


Most solar backpacks are equipped with solar panels ranging from 5W to 12W. It’s rare to find a bag with higher capacity solar panel than 12W, and any panel less than 5W is relatively useless as it will take too long to charge your devices. In general, the higher the watts, the quicker the charge time.


Standard backpacks range in size from 8L to 100L, and solar backpacks are no exception. Most normal solar backpacks are around 20-25L. This is enough space to carry the essentials and your charging devices. Be aware that the larger the bag and panel, the more weight you’ll be carrying on your back.


The overall quality of the backpack and solar panel are very important. Poorly constructed bags will not hold up when used daily or in outdoor environments, which puts your expensive electronic devices at risk.

Similarly, solar panels that are not protected or well-made can be easily damaged and will more than likely malfunction. This inconvenience can become more serious in emergency situations.

Can you charge a laptop with a solar backpack?

However, not all solar backpacks have the capability of charging laptop computers. It is entirely dependent on your battery bank and whether or not it has the capacity to accommodate an ac-powered laptop charger. Even while some backpacks are fitted with battery banks, only one of them (the Voltaic System) is capable of supporting a laptop computer. Alternatively, you can purchase a separate external laptop battery and connect it to your high-wattage solar panel to achieve the same results.

Can you wear your solar backpack in the rain?

In general, light rain will not damage the solar panels on an average backpack. Most solar backpacks come with some form of weatherproofing, although not all of them are 100% waterproof.

However, while the website may claim that the backpack is waterproof, it’s often better to be safe than sorry. Backpack rain covers are cheap and can easily fit over a bag, quickly protecting your sensitive electronics.

Will I need to purchase a battery bank or charging cords?

Most solar backpacks already come with a battery bank. Some even come with USB charging cords. However, not all do. Depending on what you plan to charge, you may want to purchase an external battery bank and cords that are specific to your devices. This is especially true for charging laptops or drones.

How long do solar backpacks last?

The life span of a solar backpack is determined by the quality of the construction and the amount of use it receives. Backpacks that are used on a daily basis will not last as long as backpacks that are just used for short excursions.

Solar panels naturally decay every year as well, albeit at a far slower rate than other types of materials. If they are not damaged in any other way, most solar panels will last for many years.

Some solar backpack manufacturers provide guarantees for their products, which can help to set your mind at rest. This type of warranty is normally for one year and may cover things like manufacturing defects, degradation, and other common solar problems. To ensure that you understand the specific policy of the supplier before making a purchase, it is essential to verify with them first.
