For the price point, I had higher expectations. 300 watts per channel is great, but you can only discharge at 1amp, which was disappointing. There isn't a "cycle" option for nimh batteries, which is commonly available in less expensive chargers. The roll / push buttons feel like they won't last. After a few charges, the "A" channel failed. It reads half the voltage that it is connected to and immediately reads "connection failure" when trying to charge or discharge, regardless of pack or connector. I had no choice but to return it. The Dynamite Passport P2 charger that I replaced it with is a much better charger with more capability, Bluetooth connectivity, 2amp discharge rate and storable charge programs.
