POLESTAR Electric Trailer Jack 5000 lbs - Heavy Duty Lift

In this review of the POLESTAR Electric Trailer Jack, the bottom line is simple: it is aimed at owners of travel trailers, campers and light-duty trailers who want hands-free lifting and a wide lift range. The jack's single biggest selling point is its robust lifting capability combined with an advanced ball screw design that promises smoother operation than basic screw jacks. Installation requires a 12V DC hard wiring hookup, so this is a practical choice for RV owners who want a powered tongue jack that handles up to 5000 lbs dynamic load and includes weather protection for long-term outdoor use.

Key Features

• Heavy duty capacity: Rated to support a dynamic load up to 5000 lbs and static lifting up to 7500 lbs, giving confidence when stabilizing trailers and RVs.
• Advanced ball screw design: The precision ball screw reduces friction and wear for smoother, quicker lifting and lowering compared with traditional jacks.
• Durable construction: Weather-resistant materials and a waterproof protective cover help the jack withstand rain, sun and snow for extended outdoor use.
• Convenient operation: A brake motor paired with the ball screw offers steady, controlled lifting that reduces strain when positioning on uneven ground.
• Versatile lift range: Retracted height starts at about 9 in with a lift to 27 in plus a 4.5 in drop leg for up to 31.5 in total travel, accommodating many trailer tongue heights.
• Built-in protections: Includes an internal circuit breaker that trips and resets automatically to guard against overcurrent situations.

Who It's For

The POLESTAR jack is best for RV and travel trailer owners who install a permanent 12V hard-wired jack and need reliable, hands-off lifting for regular hookup and leveling tasks. It suits users who value smoother operation from an advanced ball screw and want a weather-ready unit with built-in safety features.

It is less appropriate for someone who only tows infrequently and prefers a manual crank, or for users who want a completely bolt-on plug-and-play solution without hard wiring. Also, while many buyers report good value and easy installation, there are mixed long-term durability reports, so those needing commercial-grade continuous use may consider heavier industrial options.

Pros & Cons

Pros

• High lifting capacity with a smooth ball screw mechanism for efficient operation.
• Weather-resistant build and included waterproof cover protect the jack in outdoor conditions.
• Wide lift range with additional drop leg for flexible trailer compatibility.
• Built-in circuit breaker increases electrical safety during use.

Cons

• Some customers report mixed reliability over longer periods, so occasional failures have been noted.
• Requires 12V hard wiring rather than a simple plug-in, which may deter casual users.

Specifications

Our Verdict
