Review on 🔋 Lixada Solar Panel Charger - Portable High Power Monocrystalline Silicon 10W Paper Shaped Solar Panel Charger with USB Port, Ideal for Cell Phone Charging, Camping, Riding, Climbing, Travel, and Outdoor Activities. by Robert Pierce

This is exactly what I was looking for: a solar charger sufficient to charge a phone/extra battery, waterproof, small and comes without a battery pack. I agree with other users on how much power it puts out, but it's enough to charge a 5000mAh battery, which is all I wanted. As for the size, it's not a "paper" format, it's A5, or in American half a sheet: 8.5 x 5.5 ". It's better finished than I expected, with rounded corners and without sharp edges Edge makes it easy to clip in. Overall, a perfectly simple device that avoids all of the pitfalls that seem to be the bane of overthinking all other solar chargers, which means it also weighs 2.8 ounces!Nothing fancy: just the basics.
