Charger Charges!
I lost the original charger and the Ryobi screwdriver was not going to hold the charge much longer. I had the charger sooner than expected and it works just like the original. Being small and lightweight, it is easy to loose!

Most helpful!
My original charger got gnawed into pieces by mice. The new Ryobi models use a different charging system. It was great to find an inexpensive replacement so I can keep using my nifty little Ryobi screwdriver.
