Good dental care is important to our overall health. Some people like to take that extra measure and invest in an electric toothbrush and although they do a good job at keeping our smile in tip top shape, when they run out of power, they’re pretty worthless. The Be Battery Free Electric Toothbrush will keep you straight even if you’re away from civilization.

This toothbrush gives you the power and function of an electric brush but with none of the waste. Don’t worry about batteries because this gadget works on kinetic energy. Specifically, you just give the base two twists and that will give it the power to run through a brushing routine.

Other than its non-traditional power supply, this is a pretty normal electric toothbrush. It looks the same as any other one you would buy but unlike them, you can take this one anywhere and not have to worry about it running out juice, even if you’re out in the wild somewhere. Currently for preorder and isn’t shipping until the end of the year. You can still get one for $59.
