10 Best Boat Trailer Jacks 2026 in the United States

The Kohree Electric Trailer Jack is a solid choice for anyone needing to lift and stabilize A-frame trailers, including boats, campers, and RVs. It supports a hefty weight capacity of 5,000 pounds, which covers most small to medium trailers comfortably. Its adjustable lift height ranges from about 10 inches to nearly 32 inches, giving good flexibility for different trailer setups.

The jack mounts directly to the trailer's A-frame, which is a common setup, and it comes with a built-in hand crank in case you want manual control. Made from heavy-duty steel with an anti-rust coating, it promises durability even outdoors. It has two LED lights, a nice touch that makes nighttime hooking safer, plus a waterproof cover to protect it from the elements. The electric power feature means you can raise or lower your trailer easily with just a button press—much faster and less effort than a manual jack.

The jack weighs over 21 pounds, so it's on the heavier side to handle or install. Also, while it has a built-in circuit breaker for safety, it relies on a 12V DC power source, so you'll need to ensure your trailer's battery system is compatible. For those seeking a reliable, heavy-duty electric jack that simplifies and secures the lifting process, especially for travel trailers and boats, the Kohree jack is worth considering, with some consideration for its weight and power requirements.

This durability is complemented by a built-in circuit breaker for added safety.

One of its standout features is the integrated LED light, which provides illumination where it's most needed, making nighttime operations easier. The jack is also praised for its ease of installation and high reliability, backed by a one-year warranty and responsive customer service. However, some potential drawbacks include its weight of 23.1 pounds, which might be a bit cumbersome for some users, and the need for hard wiring to a 12V DC power source, which could complicate installation for those not familiar with electrical setups.

Additionally, the powder finish adds to its durability. Mounting the jack is straightforward, with options for bolting or welding, and the wind handle allows for quick and smooth adjustments. This ease of use is further supported by its 12-inch lift capacity.
