Kohree Electric Trailer Jack 4000 lb with 7‑Way Connector — 12V Motor, 22in Lift, Weatherproof

If you tow an RV, boat trailer, or camper, a reliable powered tongue jack saves time and effort when hitching and leveling. The Kohree 4000 lb electric jack combines a high-torque 12V motor, a simple plug-in installation for 7-way connectors, and built-in safety features to streamline trailer hookup and site setup. It replaces manual cranking with an easy push-button lift while still offering a manual crank backup and a weatherproof cover for year-round use.

How does this jack make hitching my trailer faster?

The Kohree electric jack uses a 12V motor to raise and lower the trailer tongue with a single button push, eliminating repeated manual turns. It reaches a maximum lift of 22 inches and retracts compactly for travel, shaving minutes off the hitching process every time.

• Plug-in operation via vehicle 7-way connector — no hard wiring needed
• 12V DC motor provides higher torque than hand cranking
• Max load capacity 4,000 lbs for most A-frame trailers and small RVs
• Quick extend/retract: 9.8" retracted to 31.7" maximum height range

Is the Kohree jack durable and safe for regular use?

This jack is built with heavy-gauge steel and an anti-rust exterior coating to handle outdoor exposure. Safety features include a built-in circuit breaker that trips under overload and restores after a brief reset, plus dual LED lights to illuminate the tongue area at night.

• Heavy-duty steel construction with corrosion-resistant finish
• Integrated circuit breaker for overload protection
• Two LEDs for nighttime visibility while hitching or leveling
• Weatherproof jack cover and included hand crank for manual operation

What are the height and compatibility details I should know?

The jack offers an adjustable drop leg with five settings to fine-tune ground clearance and tongue height. It works with standard A-frame trailers that use a vehicle 7-way connector for power and supports a broad height range to fit various trailer designs.

• Height range: 9.8" fully retracted up to 31.7" with drop leg adjustments
• Max extended lift of 22" above the mount point for added clearance
• Compatible with trailers wired for a 7-way vehicle connector
• Includes hand crank for manual override and a weatherproof cover

How easy is installation and maintenance?

Installation is straightforward: slide-mount the jack to the A-frame and plug the built-in cable into your vehicle’s 7-way connector — no additional grounding or hard wiring required. Routine care mainly involves keeping the exterior clean and covered and checking fasteners and electrical connections before each season.

• Simple plug-in setup to the 7-way vehicle socket
• No separate ground wire or complex wiring needed
• Low maintenance: clean, lubricate pivot points, and replace cover if worn
• Manufacturer support with a 1-year Kohree service warranty

Who is this for: The Kohree 4000 lb Electric Trailer Jack is ideal for RV owners, boaters, and camper or utility-trailer users who want faster, safer hitching without rewiring their tow vehicle. It fits anyone who needs a robust, weather-resistant powered jack with manual backup and clear night lighting for hassle-free setup at campgrounds, launch ramps, and storage areas.
