Electric Trailer Jack
Wondering what people are doing in terms of getting power to the jack. Mine has the 7 pin connector and I’ve been pulling out the trailer one and plugging that one in to remove the trailer. This doesn't really bother me but towing in winter I’ve had to wrap up the jack plug to keep it clean. However at -30 or colder it’s a pain having to deal with taping something over the plug and latter removing it. Is there a two into one plug or are people doing a splice so that I only have the one 7 way plug to deal with. Thanks

+1 on this, I would wire to the battery with a 30a inline fuse, if it is a small break away battery I would upgrade or only use the jack when plugged in. This way the jack works with the truck attached or not which may not be an issue depending on what kind of trailer it is.

I have electric/hydraulic disc brakes on my enclosed trailer. It has a battery for the hydraulic pump, which the electric jack is hooked up to also. I have the interior lights and loading lights hooked up to it also so I can use them when the trailer is unhooked.

In many states, it's required to have a breakaway cable for the trailer brakes. Thus, a battery isn't just a convenience feature, but a legal mandate. Some summaries are listed here.

I have two trailers with electric jacks and I installed batteries in both. Personally I believe it is the only way to go. I also have lights in both trailers so its nice to have those available without being plugged in. I installed a solar panel on the roof to keep the batteries charged when the trailers sit.
