Bought for 12v lighting in my trailer.Has a good build feel to it. Has strong magnets on it, I screwed to wood( holes provided). Installed 12v strip lights and hooked them right in to connector provided, had lights in 10mins. Could see myself buying another one for the ease of use!
Shipping was fast also! Thanks

long time.

Works great on fill rite fuel pump. Magnets are crazy strong. I prefer this to the alligator clips that i uad to hook up to tractor to fill up with. I always have a battery in the truck so this makes it easy.

It's a very convenient way to grab power for my portable 99 gallon diesel tank. I was sick of hooking up to my truck or machine batteries to pump. The electrical connector it came with (to connect to your pump motor) wouldn't securely grab my extension wires so I just changed it out to a different type of disconnect plug which works better anyway but all in all very cool.

I purchased one of these for a transfer tank that I keep on a trailer. I was pleasantly surprised with how quick and easy it was to install. The magnets are very strong and I've had zero issues with them even on very bumpy roads. This works perfectly with my 20gpm pump. I would recommend this product.
