Does this jack run off of the vehicle or is a seperate battery required?

Mine runs off the battery on my RV. When the RV (trailer) is hooked up to the tow vehicle, the battery gets recharged.

The jack is wired direct to your battery on the trailer tongue....Jack comes with ample length wire.

It runs off a separate Battery. You could wire it directly to your vehicle, but as sold, it is designed to run off a battery mounted on the trailer tongue. The leads are only about 3' Long, and made to attach directly to the battery lugs.

It powered itself off the harness in my 06 Tahoe. No need for running wires.

It's a full stand alone unit with inline fuse that needs to be run and wired up to the battery.

I hooked it up to the extra headlight wire that was taped up. You do not need to run a big power cord from the battery. Just find a power wire in the area.

No the vehicle does not need to be running. This unit can be wired to a charged 12V battery. The battery wired to the unit provides the power.

I am not sure why that would be in the listing for this product. No batteries are needed. They are just lifts. They work great, by the way. If you are interested in these lifts you may want to consider the 12". BUT, whatever you buy, you need to be sure that your jack can lift the car high enough to fit the lifts under the wheels.

It runs and charges off of usb power. You can use a usb ac adaptor and leave it on, but at some point the battery may get damaged always being plugged in.

It doesn't have either of these. You also have to turn it off and unplug it from the the vehicle otherwise if it sits to long plugged in you will have a dead battery. Other than those things it works great.

This is direct connected to your ignition switch or vehicle alarm. It is not battery operated.

No, you can keep it connected while you use the battery system of your trailer. I believe that is what you are asking. But if you mean should it be disconnected while the trailer is moving I would say, yes.

While I was researching electric jacks I saw this mentioned several times. I just ran a ground wire directly to the battery. No problems.

It is separate. It plugs into the back of the head unit and needs to be routed inside the cab somewhere.

Both. It sounds good running off battery but I use it plugged in when I can.

It gets the power from the 12 volt car or motorcycle battery. Not included. It would run off a small rechargeable 12 volt battery like you have in a kids electric car.

It will drain a battery,that is why the engine has to be running. That is what I understand.

The unit should work without battery, however it is rather exotic to be used just as a DC power supply, and it is a switching power supply, so the startup current of the lift may overload it. I would suggest adding a battery even just a small tractor battery to handle this. Also if you had a power failure, the lift would work as emergency backup
