Buying Guide

Now that we have gone over a list of the best-selling models currently on the market let’s talk more about each of the features that you should consider when buying a solar backpack. Reading our handy buying guide before you purchase can help you avoid making common mistakes as well help you get the most from your money with your purchase. Keep reading to the end of this solar backpack buying guide for answers to the most frequently asked questions about solar backpacks.

Features to Consider When Shopping For a Solar Backpack

If you are shopping for a solar backpack you should consider each of the following features before you buy. The features can have an effect on the price, performance, or appearance of the backpack and comparing and contrasting the features of the bestselling solar backpacks on the market can help you determine which one is the best for you.


Solar backpacks cost a lot more than regular backpacks because solar power technology has not advanced to the point where everyone is doing it, it does cost more to manufacture these products because of supply and demand. Other features other than the solar panels that will have an effect on the price of the solar backpack is the materials that are used in the construction of the bag itself.

Because solar backpacks generally carry electronics, hence the need for the USB ports and solar panels, it is also essential that the material used in the construction of the bag itself be made out of a water resistant fabric. The price to manufacture waterproof backpacks with a soft inner lining for electronics is more than that of a regular book bag which is why the premium price tag on solar backpacks is worth it.


Related to the price, is the brand. The brand of the bag matters in terms of price, appearance, and performance because different manufacturers use different materials and technologies to fashion their products. If you want to skip past inefficient products and get straight to the best backpacks then we recommend looking at reputable brands first.

Voltaic and Sunnbag are both reputable dealers of solar backpacks that have a reputation for high-quality solar backpacks. The style of the bag is also important, especially if you plan on using it as a daily backpack and not just for the occasional travel excursion. The brands also may also offer different warranties and customer care which is important to take into consideration as well as the style of the bag.

Cheap knockoffs of the popular brands should always be avoided because although they promise the same performance they use less expensive materials which are not as high-quality and the performance will not be as good. When it comes to solar backpacks you should look for brands that offer at least a thirty day warranty if not a year as well as brands who are committed to rigorously quality checking their products for safety and performance before shipping them out.


Usually backpacks will measure the size in terms of liters. Most solar backpacks are around 20 L, while the smaller ones may cost a little less. The size of the solar backpack is important depending on what you plan on carrying in it.

One feature that people pay a lot of attention to is the laptop sleeve. The size of the laptop sleeve is important in order to keep your device safe it will need to have a big enough space. You can expect to fit a 15” to 17” laptop in most solar backpacks.


In addition to the size of the backpack you should also think about the weight. You should be able to see what the weight of the backpack is in the product description before you purchase so you can figure out how heavy or light it is. For long treks a lightweight backpack is ideal.

You want the backpack to be both durable and lightweight. If it is too flimsy it may not hold up well over time or protect your devices if you carry a laptop or tablet. You need to think about not only the weight of just the backpack itself but also the weight of what you plan on storing in it and how far you will be carrying the backpack.

The solar panels are going to weigh down the backpack more than a regular backpack so you can expect it to be at least a few extra pounds heavy. Having high-quality shoulder straps can help spread out the weight of the bag and extra padding on the back and shoulders helps to prevent soreness after a long hike.


The storage within the bag is not just limited to the storage of the main compartment. In addition to a large inner compartment most solar backpacks also include a variety of other pockets and storage spaces for devices, electronics, water bottles, and more. When shopping for a solar backpack you should consider what sort of electronics and other things you plan on putting in your backpack so that you can decide how many pockets and what kind of space that you need.


The handles and straps on the bag are important for your comfort especially for hiking and camping. Backpacks should have two shoulder straps, but the design of the straps can vary. Some straps criss cross over the back while others hang down loosely. The best shoulder straps for a heavy-duty backpack like this are those which have some extra padding and which spread the weight out evenly so that it is not focused in one spot.

Another handle that you may find on the bag will be one near the top of the bag. Having an easy-lift handle at the top of the bag is great because without it your only option is to have the backpack on your back or hanging loosely by one of the straps. The backpack should ideally have two high-quality shoulder straps as well as at least one easy lift handle on the top of the bag.

The materials and the stitching on the handles is important because often the shoulder straps and handles and the first things to fall off of a backpack. High-quality straps means that you will get more use out of a backpack over time before you have to worry about sewing up a broken shoulder strap.


It can be hard to find solar backpacks that do not look like basic black camera gear bags, but with a little bit of hunting you can find solar backpacks in many of your favorite colors. Neutrals and blacks are ideal for outdoor use because they do not stain as easily as light colors.

You may end up paying more just for the color of the backpack if it is a sought after color and for this reason going with a basic black or grey may be reasonable. You do not have to settle for an unattractive backpack, Sunnybag and Voltaic both make very good looking bags that you can carry around every day. You can even remove the solar panels on some bags to convert it to a regular looking backpack.

Charging Ports

Most solar backpacks can charge a wide range of devices by liberty of an integrated charging port. This charging port is usually a USB charging port, but this can vary. While a USB port is acceptable for almost all devices, some laptops like new Macbooks do not use a USB charger and instead use a USB-C charger so this is something important to keep in mind when shopping. You want to make sure that the solar backpack that you buy has the appropriate type of charging port for the devices that you need to carry on the go.

Solar Panels

One of the most important features of the bag is of course the solar panels. The quality of the solar panels will determine how fast your devices can charge. Here is a list of things to consider about the solar panels:

  • Testing

Solar panels are new technology and rigorous testing should go into all consumer products that include relatively new technologies such as solar power.

  • Wattage

The wattage of the solar panels charging capability is important when it comes to your devices. You may want to check and see what voltage is required for your devices. For reference, most iphones and other smartphones have a voltage between 5 and 10 W.

  • Battery pack

The inclusion of a battery pack with the solar backpack means that you will be able to charge your devices even when the sun doesn’t shine because the solar panels will charge the battery pack. If one is not included with the backpack you can buy them separately and use them together to store power for later.

  • Removable

Some solar backpacks feature solar panels that are removable whereas others are permanently affixed to the bag. Some people like being able to take the solar panels off because it can make the bag more lightweight or change up the style for a more casual daily look.


When shopping for a solar backpack you should look for models that come with a free warranty. Solar backpacks can come with a premium price tag so you don’t want to waste your money on an inefficient product and a warranty protects your purchase in case of parts defects.

If you want to find out more about the warranties offered on a particular backpack you should be able to contact the customer service department of the manufacturer. All reputable manufacturers should have a customer care center set up that can help you with warranties and other questions either by email or over the phone.
