Roll as long as you can!
These curse smartphones always drain when you shouldn’t. We know the solution!
The Green House charger does not require an outlet and does not need sunlight. With the help of the built-in dynamo, we can gain the power needed for a 5-minute conversation by turning for 3 minutes. The structure, called GH-DYB3, also features three AA nickel-metal hydride rechargeable batteries, so you can pack some electricity from home if you don’t want to wind it up. If they run out, then there is nothing left, we can crank up to suffocation.
