I wonder if it would be feasible to use these for dead RV batteries, so you can raise and lower your hitch until you get the rig connected to your tow vehicle.
I like the inverted main category picture with the mirror image ‘instant power’.
Did you miss the Backwards Day memo?
Yesssssss…Somebody dropped me off the list apparently.
Pretty sure that the power delivery (in parentheses) should reflect 400/600/750, respectively…versus all intimating 400Amps.
Beyond that, likely a better deal than the Harbor-Freight clones.
