6. RAVPower Solar Charger
This product is a great option for backpackers, who need to keep portability and weight in mind at all times. Unlike the other models, it has a handy pocket for the charging cables and your devices, perfect for keeping your backpack organized. This charger is half the weight of similar solar chargers but equal in power. It folds up to a small rectangle, but when folded out, it can be configured as a 3D pentagon-shaped solar panel, able to fully catch the sun’s rays at different angles. It can be used to cover the whole of your backpack as you’re hiking, optimizing the amount of energy you can harness from the sun.
We wouldn’t recommend this for use on campsites primarily, as you have to be careful not to set this product upon rocks, sand or concrete, otherwise it can overheat. It’s much better used on your backpack, to conveniently charge your devices as you hike throughout the day. Using the solar charger in this way makes storage a breeze, and your devices will charge as you concentrate on the more exciting things. Although this product is water-resistant, it could be more so, so we would recommend to only use it on sunny days for optimum effect.
This model will charge your devices very quickly. Its 24W solar charging technology increases the efficiency of charging by up to 21.5% – 23.5% compared to some other models. It also has three ports, so this is a much better option for you over the last two models if you’re going camping with a group, or have multiple devices you want to charge while you’re camping. Similarly to the other models, this solar panel has iSmart technology, which means the right amount of charge is delivered to your device to avoid overcharging or short circuit.

And, because it doesn’t have an inbuilt battery, it’s even lighter and easier to backpack with than most other solar chargers on the market.
