Product purpose

The VEVOR EJ3500B is a DC 12 V electric tongue jack rated for 4000 lbs of lifting capacity. It is designed for owners of RV trailers, horse trailers, utility trailers and yacht trailers who want push-button hitch height adjustment instead of manual cranking.

Build integration

The unit mounts on a standard 50 mm hole pattern and draws up to 350 W from the trailer’s 12 V system. A 460 mm stroke provides 18.11 inches of travel, while the overall height range spans 9.84 to 33.85 inches. The package includes a crank handle for emergency manual operation and a waterproof sunshade cover to protect the motor housing.

Buyer fit

This jack suits trailer owners who need 1815 kg capacity and a 12 V power source on board. Buyers who require a higher weight rating, a different voltage supply or a mounting pattern other than 1.97 inch centres should look at alternative models.

Questions about this item

How far can the jack extend before the 4000 lbs capacity is reached?

The lifting range runs from 9.84" to 27.95" with a stroke of 18.11", so the jack reaches its full 4000 lbs rating anywhere within that span.

What is the motor's power draw and voltage during continuous operation?

It runs on DC12V and draws a maximum of 350W while lifting or holding a load.

Which trailer tongue bracket is needed for the 1.97" hole pitch?

A standard 50 mm (1.97") bolt-pattern bracket matches the jack's mounting holes directly.
