ProTek RC Transmitter Charge Lead (DC Plug to 4mm Banana Plugs)
I just received this power supply to charger patch cord. The red (positive) banana plug goes to the center of the 5.5 mm charger plug.....good.....that works with my chargers. I got this cord to use with my new Protek 10 amp 12 volt power supply from Amain. This power supply fresh out of box today works great so far as it should, the fan runs all the time yet is silent.

Back to this patch cord. The only thing not perfect is the wires are very thin gauge so if you are carrying this around often in your hobby travels it may not be super durable. Or if your charger is routinely pulling more than six amps this is probably not the best cable to use. Still for $2.99 it's fine for my turnigy accucel 6 amp charger mostly using it with 850-1300mah 3S and 4S lipos for the smaller airplanes and blade 300x helis.
