How to Choose Solar Backpack?

We are now living in a technological world where power is one of the most basic resources. For most people, staying connected through devices like smartphones or tablets is essential, especially during outdoor activities like hiking. Reliable power is a safe guarantee because it can accommodate all the devices you will use.

Thus, a solar backpack can become a valuable tool. It generates power via the rays of the sun, which makes it very convenient and environmentally friendly.

What to Consider When Buying a Solar Backpack


Given that there is a rich supply of different types and brands which seem all good and worth buying, you might feel puzzled about how to choose the special one. Taking what we have discussed above into account, we can look at the factors you need to consider when choosing one.

Now, let’s look at some points and tips we gathered to think about when selecting:

Power Bank

If you want to buy a solar backpack for outdoor purposes, you have to learn about whether there is a power bank included in the pack. The power bank determines the amount of energy you can store. And when you go outside, you will take many different gadgets, including smartphones, tablets, and torches.

So a reliable power bank is primary for your trip. Besides, you should pay attention to the charging possibility as well as the charging speed, to make sure that it manages to charge all the appliances and devices you need in the wild.

External USB Ports


Besides considering the power bank, another important factor you should be concerned about is if there are enough external USB ports to meet various charging needs. Generally, different backpacks have different settings, among which the USB port is a very basic consideration.

The reason is that you need sorts of different ports for your specific devices. For example, the port used for tablets sometimes doesn’t work for phones. So multiple USB ports can eliminate your worries by getting all the appliances charged respectively.

Size and Weight

An obvious issue is that the solar backpack could be very large and heavy. The reason for this is that the solar panel included in the backpack is typically quite heavy. That means you are carrying a movable battery that is used to store power to charge those appliances.

The larger the bag and panel, the larger the size and weight you’ll be carrying on your back. If you want big storage, the battery bank should be large and heavy. Most normal solar backpacks are about 20-25L. So the space is big enough to carry your needs and your electronic devices. You can choose one according to your multiple demands.



Although compartments are not as significant as the other mentioned features, it is still worth thinking about when you are going to buy a solar backpack. Since the compartments roughly represent the storage capacity of a backpack, buyers usually can get to know how big the backpack is, and that could be a preference consideration for some people.

Those who plan to be outdoors for several days, in particular, need to pack a lot of items. Therefore, enough compartments can accommodate considerable items. Also, users can find what they need quickly because things are divided into specific compartments, which provide many conveniences.

Solar Panel

As the most essential component of a solar backpack, the solar panel should draw your attention. And there is more than one matter about the solar panel that should be valued before buying a solar backpack. The first and foremost one is the specification of the solar panel, which mainly relates to the wattage.

You must know the range of the wattage, for it determines how long it will take the PV module to get your appliances charged. Usually, if you want to charge your larger electronic devices in a comparatively short time, you should choose those with higher wattage (between 7-10 watts).

Then, you will get a high charging efficiency. Another factor is whether the solar panel is removable. If there is a removable solar panel, you can have more flexibility when using it.



Compared with a regular or indoor backpack, an outdoor radio could suffer more wear and tear. You could carry a solar backpack anywhere you spend your leisure time. If you go camping or hiking, the backpack might experience many reels, stumbles, bumps, and rubs.

Sometimes, it could encounter water contact or heavy rain. So it has to have prohibitively durable housing to protect itself from being damaged. Meanwhile, it should be water-resistant, because the outdoor weather could be very changeable.

And all the electronic devices in the backpack need protection. So select those with tough and waterproof fabric, you can use it for a much longer time and need not worry when bad weather comes.
