This is super cool, particularly if you’re going camping, hiking, working outside, or just on a trip. You can use solar power bank for any USB device, so yes, for your tablet, phone, or laptop even, and it’s the size of a smart phone. Basically one side of the device is a solar panel that uses the sun’s rays to collect and store a reserve power source. It’s constantly renewing so long as it’s in the sun so you can for instance place it on the dash of the car when you’re heading somewhere then slide a solar charger in your bag when you set off and you’re carrying a dependable back up source of power.
So, next time you’re watching your phone power off at the worst possible moment, think back to this moment when you learned about this awesome solution and think, did you grab power bank when you had the chance?
