There were many different Duo adapters that all looked the same. The most recent one (for 280c and 2300c) was identical wattage (36w) to the 2400 adapter, so it should charge at the same rate. The older ones (25w) would work, but would charge the battery more slowly. They don't list the wattage on the Duo adapter, but rather the voltage (24v) and the draw (1.04A for the 25w adapter, 1.5A for the 36w adapter). You could probably pick one up on eBay for cheap, but I'd make sure to get the 36w adapter. Also, any of the 45W adapters (3400, PBG3, YoYo) which have the larger plug should work fine.
