Another tiny, portable, and highly mobile option, the Big Blue 28W Solar Charger, is an affordable $79.99 option on Amazon. The most notable feature of the BigBlue 28W Solar Charger is that it only weighs 1.57 pounds and is fairly tiny when fully folded at 11.1 x 6.3 inches large.
The way these panels fold makes it small enough to fit in most backpacks without adding much extra weight to your gear. The device is powered with a branded SunPower Solar Panel with a solar cell efficiency of 24% and comes with three USB-A ports, enabling the direct charging of multiple devices.
That being said, the device is limited to a 28-watt maximum, meaning that larger devices, like laptops, won’t be able to be directly powered by the device unless using it to store power in a power bank. Many complaints about the device point to a lack of power and difficulty finding the right angle to charge the device efficiently, as the device lacks an angled kickstand.
Ultimately, the mobile solar panel you get for your camping trips will depend highly on your needs. Luckily, all of these devices serve as reliable options regardless of your scenario. Whether you need a power source and portable charger for laptops and minifridges or are just looking for an alternative for an external battery for your phone, one of these options should suit your needs.
