I use the Energizer 15 minute charger(buy at Walmart) with their excellent nmh batteries. I have maybe 36 batteries and if need be they can be charged in 15 minutes...4 at a time. I have two chargers so I can charge an entire transmitter pack at one time. Did I mention they are EXTREMLEY FAST

OH BTW they come with an ac adapter and a 12v car plug and I use the ac adapter on my Acuccel chargers
