POLESTAR Electric Trailer Jack 3500 lb A-Frame Tongue Jack — 12V Hardwired, LED Lighting

POLESTAR's 3500 lb electric trailer jack is a weather-resistant, hardwired 12V A-frame tongue jack that lifts and stabilizes trailers quickly and smoothly from 9" to 31.5" with a built-in brake motor and LED lighting.

Replacing manual crank jacks, this POLESTAR electric tongue jack combines a high-efficiency thread friction mechanism with a heavy-duty motor and waterproof construction to deliver reliable trailer lifting for campers, boats, and utility trailers. It hooks directly to a 12V trailer battery, includes a rain cover and circuit protection, and offers a broad lift range that handles most A-frame couplers. The design emphasizes smoother operation, reduced wear, and practical features—like integrated LEDs and a drop leg—to streamline hitching, unhitching, and campsite setup.

How much weight can this jack safely lift and support?

The POLESTAR jack is rated for dynamic loads up to 3,500 lbs and provides a static lifting capacity up to 5,000 lbs, making it suitable for many single-axle and smaller tandem-axle trailers. Dynamic rating refers to regular lifting while mounted; static capacity indicates the maximum supported load when stationary and secured.

• Dynamic lift: 3,500 lbs—appropriate for most RVs, boats, and cargo trailers within that range.
• Static support: up to 5,000 lbs for stable long-term positioning when lowered and braced.
• Designed for A-frame tongues and compatible with standard coupler heights within the lift range.

How does the thread friction design and motor improve everyday use?

The advanced thread friction mechanism reduces mechanical drag and wear, so lifting and lowering feel smoother and require less motor effort. Paired with a brake motor, this system gives controlled motion during operation and increased longevity compared with basic screw-jack designs.

• Smoother travel for accurate coupler alignment and less shaking during lift/lower cycles.
• Lower internal friction reduces heat and prolongs component life.
• Brake motor enhances stability on inclines and prevents uncontrolled descent.

What features protect the jack from weather and electrical issues?

The jack is built from weather-resistant materials and comes with a waterproof rain cover to shield the motor and housing from moisture and debris. It also includes a built-in circuit breaker that trips and resets automatically if amperage spikes, protecting wiring and the motor during abnormal conditions.

• Weather-resistant finish and sealed components for outdoor storage and use.
• Included rain cover for extra protection at campsites or marinas.
• Internal circuit breaker for overcurrent protection and safe operation.

Will this jack fit my trailer and how is power connected?

Designed for A-frame tongue setups, the POLESTAR jack fits most standard mounting plates and complements trailers with a 12V battery supply. Hardwiring is straightforward: connect positive and negative leads to the trailer battery following the included manual and disconnect power before installation for safety.

• Mounting: made for A-frame couplers and standard bolt patterns—verify plate compatibility before purchase.
• Power: direct 12V hardwired connection for stable performance; follow wiring guide.
• Lift range: retracts to 9" and extends up to 27", plus a 4.5" drop leg for greater reach (total up to 31.5").

Who is this for: The POLESTAR 3500 lbs electric trailer jack is ideal for owners of small-to-medium RVs, boat trailers, utility trailers, and off-road rigs who want faster, safer hitching without manual cranking. It's a good match for frequent travelers, weekend boaters, and anyone who needs a durable, weatherproof jack that simplifies setup in dim light thanks to its integrated LEDs and dependable brake motor. Before buying, confirm your trailer’s tongue type and mounting compatibility and ensure a properly charged 12V battery is available for installation.
