The Duo LCD Charger for ContourHD Battery from Watson conveniently charges two batteries simultaneously, drawing power from either an AC wall source (an AC cord with two-prong plug is included) or a 12/24V DC power source (a DC car charger is also included). Additionally, the Duo Charger features a USB power output to charge and power MP3 players, phones, digital cameras, and other devices with a USB power input.
With two easily interchangeable plates, the intelligent charger can also be used for other battery models that are not listed above via the separate purchase of an additional battery plate that's compatible with the intended battery model.
The intelligent charger features an LCD display that graphically shows charge status for both batteries. This allows you to test batteries instantaneously, so you can easily decide which Li-ion cells to bring with you for the day. With protection against overcharging, overheating, and short circuit, the Duo Charger safely, conveniently, and quickly recharges up to two compatible Li-ion batteries and one USB-powered device.
