Whether you’re camping, waiting out a power outage, or fixing your car on the side of the road at night, having a ready supply of light is handy indeed. Maybe the coolest lamp out there is the LuminAid PackLite.

The LuminAid PackLite is actually a two-in-one lantern and charger. It’s inflatable, solar-powered and totally waterproof. No wonder Mark Cuban got LuminAid $200,000 on Shark Tank.

The PackLite breaks down and inflates in seconds, meaning you can tuck it away until the moment you need it. Other features include a variety of flash settings, a micro-USB outlet, a high-efficiency solar panel and a built-in 2,000mAh battery.

The thing even floats, and can dunk into up to a meter of water.

These are tough, all-purpose lights, which is why the company donated more than 25,000 to support disaster relief efforts in Puerto Rico.
