Lightors, Reusable AA and AAA Batteries That Can Be Recharged Via a Built-In Micro-USB Port
Lightors are standard-sized reusable AA and AAA batteries that have a built-in micro-USB port, letting users refill their charge up to 500 times using a stand USB cable. The batteries display a red light when charging and a blue light when they’re finished, a process that should take around three hours all told. The project is currently seeking funding on Kickstarter.
