Truly a plug-and-play charger for Spektrum batteries. It automatically determines the appropriate charging voltage, so while this charger isn't necessarily fast, it is quite efficient and charges the batteries as fast as reasonably possible while preserving the battery integrity. It also accepts two types of Spektrum - however be warned that there are many different types of adaptors needed for Spektrum batteries, so you may need to buy an adaptor or two if you're like me and have all different kinds of batteries.

Works perfectly on Spektrum smart batteries. Any other batteries can still be charged if you purchase adapters separately.
