Monster Power MB8-PROCHGAA ProCharge Power Battery Charger

Charge your PowerCells anytime using the supplied wall outlet or car adapter. Smart charging technology supplies power to each PowerCell individually, so you can charge one to four at any time and they'll all charge at the same capacity without under or over charging! ProCharger's LEDs light up when charging, turn off when done, and flash when an alkaline or bad battery is mistakenly placed in the ProCharger.
