Factors to Consider When Buying Solar Panel Backpacks

Solar-powered backpacks have made life easier for most people as they can easily charge a phone without an electric power source. Solar panels use solar energy to charge most devices, and they are environmentally friendly as the solar power that they use is renewable and sustainable. Due to the variety of solar backpacks in the market, choosing the one to buy may be overwhelming, and because of that, we have come up with this list to help narrow it down for you. We shall now discuss what features you need to consider before buying a solar backpack to charge your phone when you are not near a power source.

a). Weight

When you go hiking or running, or even cycling, you would not want to have a heavy solar backpack that will drag and weigh you down. Instead, you'd like something lightweight and easy to carry and walk with. In addition, a lightweight backpack is more comfortable. Therefore, if you are looking for a hiking backpack, you may need to buy a lightweight one.

b). Charging Time

The best solar backpacks charge relatively fast, and this should be a consideration when making a purchase. A solar panel with a higher capacity will take more time to charge, and the one with a lower capacity will charge faster. Solar panels with higher capacities may give an extended charge. Therefore, you will have to consider what you need more.

c). Charging Voltage

The charging voltage of a solar panel is an important factor to consider to ensure you get one that can charge your device well. For example, for a solar backpack to charge your mobile phone or tablet, ensure it is 5V and above to charge efficiently. In addition, most USB devices usually need a 5V output to charge efficiently, and for that reason, you will need your solar panel, whose output is at least 5V.

d). Durability

When you spend money on something, you want it to last for as long as possible. If you plan to use your solar backpack more frequently, you will need it to be even stronger and more durable. Most solar backpacks are made with a waterproof material, making it long-lasting as it does not absorb water, which can damage the contents and the bag itself. Durable solar backpacks will also ensure that your solar panel and the contents of the bag are safe. If it is weak, it can easily tear and drop devices. The solar panel itself also needs to be durable so that the bag does not lose its functionality.

e). Sockets, Pockets, and Detachable Solar Panels

You are more likely to pack your solar backpack with many essentials that you may need to use while hiking or jogging or doing whatever you will be doing with it. Therefore, a bag with enough compartments and pockets will have enough storage space for your items. Slots for water bottles will also be helpful if your bg does not have a hydration bladder. Other smaller pockets for smaller gadgets will make it easy for you to be organized. Also, a solar backpack that comes with a removable solar panel is a more versatile option as you can remove it and carry it separately or use the bag alone. If you are camping, you can even detach it and use it in the direction of the sun.

f). Budget

Budget is an equally important factor to consider when you want to buy a new solar panel backpack. Weigh the different options available and their prices and what you have kept aside for that purpose. Whenever you plan to buy a new item, your money should always be enough for that specific device. Therefore, ensure you have enough money for whatever choice of a solar backpack.

I hope you enjoyed reading this review on the best solar charger backpacks and the features to consider when buying one. Backpacks equipped with solar panels make work easier because they are versatile; they are backpacks and solar power source in one. So you can carry your items in the bag and use the same bag as a power source to charge your devices.
