NoPoPo Water Batteries run on Water
You may not want to believe it but the NoPoPo Water Batteries are real and as the name suggests they do run on water. It’s as awesome as you think it is as it can provide you from 3 to 10 minutes of Juice and all cause of a chemical reaction and a few drops of water. They can be used even if you find them lying around in some drawer after 20 long years. Speaking of using these water batteries, they can for a matter of fact be used with any liquid. If you are thinking urine, yes urine too; also sweat, saliva, alcohol, rain water, sea water, whiskey you name it! The makers APS-J strongly recommend you to use simple tape water for ultimate performances, but if urine or saliva is all you got then there is no stopping you.
Each battery can be charge maximum 3 times before being completely worn out. The bad news is that these NoPoPo Water Batteries will be available in Japanese store shelves later this august. The batteries are apparently available in USA too. You may find them here.
