This is the piece of hardware you need if you have a large number of Ryobi batteries that need charging. The P135 supercharger holds up to six of any Ryobi battery. This is able to charge some models like the P102 in only a half an hour. This particular system optimizes storage space with the convenient carrying handle. You can either lay it flat on its side or vertically on either one of its ends. You can even mount it on a wall with the conveniently located brackets on the back. Imagine the possibilities with all of that extra space freed up.The P135 system even has you covered if you need to charge your smartphone. It has a USB port for anything you’d need using that technology. Leave your dead batteries in the P135 overnight after a long work day, return in the morning, and your fuel cells will be charged and ready to go at it for another day, every day.
