This is a hand crank. Sometimes needed if your leveler sticks, rusts, etc.
I use this one, similar to the one above
Camco RV Leveling Scissor Jack Socket Drill Adapter With 1/4" Quick Connect Shank, Works With All 3/4" Hex Drive Jacks
Remember, the stabilizers are for stabilizing , not lifting or leveling your trailer.
I bought a cheapo Harbor Freight cordless. Good for several up and downs per charge.
