R-BATTERY / Electric device

R-BATTERY
R-BATTERY

Actually, there still remains some power in the used batteries. This R-battery takes the form of a D type battery into which used AA or AAA batteries can embed. Then, by transforming and collecting the remaining power in the used batteries, we can use the device again and again. We will find three holes when open-ing the cover of the r-battery just for the AA or AAA batteries. Then the device can collect the remaining power in the
used batteries after we lose the lid. And the LED light strip in the side of the R-Battery shows the amount of the power collected.
