The electric pump in my box is over 15 years old and still going strong. I use the cheap manual hand crank for my gas powered planes. I still have a power panel in my box too. I do use it but the battery died a long time ago and I use a auto jump start battery and connect it to two of the panel plugs on the outside. It only powers my pump and during the winter to power the glow driver for some added juice. I could live without the electric pump and power panel but what the heck, I have had them for years and they are in my flight box.
