DEWALT 20V MAX Battery Charger, 4-Ports, Simultaneous Charging for 12V and 20V Max Batteries (DCB104)

Can charge 20 volt and 60 volt . Little high on price but when you need batteries charged its the way to go . We use two of them on job sites . So we always have batterys ready to go

Wall mounting requires very long screws but i coupled this with a tool holder and a battery holder so that I have a nice wall of battery powered tools.

I liked and recommend.
