The electric unit uses the oil in the pan - that's why it needs a motor. So you're not carrying around a big bulky reservoir with an extra 3 quarts or so of oil in it. I suspect that an accusump with solenoid, etc will be about the same price as the electric system.- but takes up WAY more space and weighs a lot more.
