Portable Solar-Powered Charger
The best inventions combine multiple products into a single, compact-sized device. Here, we have a portable source of light that doubles as a phone charger and also makes for an excellent paperweight. This device can supply over 12 hours of light or about half that amount of time to charge multiple smartphones at once.
As you can see from the picture, the light isn’t the brightest, but this thing wasn’t designed to illuminate hundreds of feet of pathway. It’s designed as a simple nightlight to create a soothing atmosphere as you travel through the wilderness and get eaten by bears.
