POLESTAR Electric Trailer Jack 5000 lb A‑Frame Tongue Jack — Ball‑Screw Drive, LED Lights, Waterproof Cover

If you tow trailers, RVs, boats or off-road rigs and want faster, safer hitching without manual cranking, this powered tongue jack delivers. Built around a high-precision ball screw and a brake motor, the unit converts electrical power into smooth vertical motion while protecting components from the elements. It includes a waterproof rain cover, integrated LEDs for night visibility, and a drop leg option to extend total lift height—features that simplify hitching on uneven ground or in low light.

How does the POLESTAR jack make hitching quicker and safer?

The electric motor and ball screw eliminate hand-cranking, reducing physical effort and minimizing jerky movement that can misalign couplers. The self-contained brake motor maintains consistent lift under load for controlled lowering and secure positioning. Built-in circuit protection prevents overloads, and the LED lights illuminate the ball and coupler at night.

• Powered lift replaces manual crank; faster hitching operations.
• Ball screw design reduces friction for precise, smooth movement.
• Brake motor holds load steady during adjustments and lowering.
• LEDs focus light on the coupler for safer night hookups.

What loads and lift range can this jack handle?

The POLESTAR jack supports a dynamic rated capacity of 5000 lbs with a static lift capability up to 7500 lbs, making it suitable for many travel trailers, toy haulers and small boats. Retracted height starts around 9 inches and extends to 27 inches, plus a 4.5-inch drop leg option, giving a maximum reach near 31.5 inches to match different tongue heights.

• Dynamic load rating: 5000 lbs for typical towing scenarios.
• Static lift rating: up to 7500 lbs for non-moving support.
• Lift range: roughly 9" retracted to 27" extended; drop leg adds 4.5".
• Adjustable reach suits varied trailer coupler heights and inclines.

How durable and weatherproof is the POLESTAR jack?

Manufactured from heavy-duty, weather-resistant materials, the jack is designed to withstand outdoor exposure to rain, sun and road grime. Corrosion-resistant finishes and a supplied waterproof rain cover extend service life in coastal or wet climates. An internal circuit breaker trips under excessive amperage and resets automatically, protecting the motor and electronics from damage.

• Weather-resistant construction for outdoor, year-round use.
• Supplied waterproof rain cover shields electronics and switch.
• Automatic circuit breaker protects motor during overloads.
• Robust components reduce maintenance frequency and downtime.

What installation and convenience features are included?

The jack is designed for straightforward A-frame installation with standard mounting patterns and an electric plug interface. Integrated LEDs illuminate the ball and coupler for low-light setups, and the power unit works with common 12V trailer battery systems. The ball screw plus brake motor delivers consistent, controllable motion for precise leveling without extra tools.

• Standard A-frame mount for compatibility with most trailers.
• 12V-compatible operation works from trailer battery power.
• LED work lights assist nighttime hitching and inspections.
• Ball screw and brake motor for controlled, low-effort lift/lower.

Who is this for: The POLESTAR 5000 lbs Electric Trailer Jack suits RV owners, boat trailers, work trailers and anyone who frequently connects and levels trailers. It benefits users who prefer less manual labor, need reliable night-time visibility, or require a weatherproof, high-capacity jack for seasonal towing, storage or off-road adventures.
