We researched and compared the top automatic trailer jacks on the market, analyzing manufacturer specifications, industry safety standards, and aggregated owner feedback. Our evaluation focuses on performance, durability, ease of use, and value to help you choose the right jack for your trailer. Whether you need power, reliability, or portability, we have a pick for you.

1. Barker 3000 lb. Electric Trailer Jack: Top Pick

🛒  Check Price on Amazon →

The Barker 3000 lb. Electric Trailer Jack is our top pick for its balanced mix of power, speed, and durability. Based on owner feedback, the 14 inch stroke lifts most trailers quickly, and the welded steel frame holds up well over time. We found that the 12V motor provides consistent performance even in cold weather, though some users noted the included wiring isn’t the longest for larger trailers.

However, this jack is not ideal for heavy-duty fifth-wheel trailers exceeding 3000 lbs. tongue weight or for those seeking a lightweight solution. The added weight of the motor and housing may be a consideration for weight-sensitive setups. If you need a higher capacity, consider our heavy-duty pick.

• Powerful 3000 lb. lifting capacity suitable for most single-axle trailers
• 12V DC motor with quick 14 inch stroke for rapid deployment
• Durable welded steel construction with corrosion-resistant finish

Pros: Fast and reliable electric operation; Sturdy build with solid mounting bracket
Cons: Heavier than manual jacks, adds weight to tongue

2. Lippert Components 1357100 Electric Trailer Jack: Runner Up

🛒  Check Price on Amazon →

The Lippert 1357100 is a strong runner up, offering a higher 3500 lb. capacity and longer stroke than our top pick. In our research, owners praised its weather resistance and the manual crank feature that works when power fails. The 18 inch stroke is particularly useful for trailers with uneven terrain or high clearance needs.

That said, the mounting bracket may not fit all trailer tongue configurations without modification, which could be a hassle. Some users reported that the motor can be slow under heavy load. If you have a standard A-frame trailer and prioritize lift height, this is an excellent choice, but for lighter trailers, the Barker may be more than adequate.

• 3500 lb. capacity ideal for larger boats and campers
• 18 inch stroke for extra ground clearance
• Weatherproof motor housing with manual override

Pros: Long stroke provides excellent lift height; Manual override functions even with dead battery
Cons: Installation can be tricky for some trailer frames

3. Fulton F2 2500 lb. Electric Trailer Jack: Best Value

🛒  Check Price on Amazon →

The Fulton F2 is our best value pick, delivering reliable electric operation at a budget-friendly price point. Based on spec comparisons, the 2500 lb. capacity and 12 inch stroke are sufficient for many small boats, utility trailers, and pop-up campers. Owners appreciate the straightforward installation and the included wiring harness that simplifies setup.

However, this jack is not designed for heavy loads or trailers requiring significant lift height. The motor is less powerful than higher-end models, and some users noted slower lifting under maximum capacity. If your trailer tongue weight exceeds 2500 lbs. or you need a longer stroke, look elsewhere. But for light-duty use, it offers solid performance without breaking the bank.

• Affordable electric jack with 2500 lb. capacity for small to medium trailers
• Compact 12 inch stroke fits tight spaces
• Easy bolt-on installation with pre-wired harness

Pros: Great value for the price; Simple installation for DIY users
Cons: Lower capacity may not suit heavy trailers; Stroke length limited for high-clearance needs

4. Dexter EZ Lube 12V Electric Trailer Jack: Durable Choice

🛒  Check Price on Amazon →

The Dexter EZ Lube jack stands out for its exceptional durability, thanks to its integrated lubrication system and weather-sealed components. In our evaluation, this jack is built to withstand harsh environments, making it a favorite among boat owners who frequently launch in saltwater. The 3500 lb. capacity handles most tandem-axle trailers with ease.

On the downside, the EZ Lube system requires periodic grease replenishment, which some owners find unnecessary. The jack is also heavier and pricier than simpler alternatives. If you trailer in corrosive conditions or prioritize long-term reliability, the Dexter is a solid investment. But for occasional use in dry climates, a simpler jack may suffice.

• Integrated EZ Lube system for easy maintenance
• 3500 lb. capacity with heavy-duty steel housing
• Weather-sealed motor and switch for longevity

Pros: Excellent corrosion resistance and build quality; Lubrication system extends lifespan
Cons: Heavier and more expensive than basic models; EZ Lube adds complexity

5. Trailer Valet 5X Heavy Duty Electric Trailer Jack: Heavy Duty

🛒  Check Price on Amazon →

The Trailer Valet 5X is our heavy-duty pick, engineered for the biggest trailers with a 5000 lb. capacity. Based on safety standards, the integrated lock is a standout feature that prevents the jack from lowering unexpectedly. Owner feedback highlights its robust construction and ability to handle heavy loads without strain.

However, this jack is overkill for average trailers and its weight can be a drawback during installation. The high price reflects its capabilities, but not everyone needs that level of capacity. If you own a large fifth-wheel or commercial trailer, the Trailer Valet 5X is a top contender. For smaller trailers, it’s unnecessary and impractical.

• Massive 5000 lb. capacity for heavy fifth-wheel and gooseneck trailers
• Anti-corrosion coating protects against rust
• Integrated safety lock prevents accidental lowering

Pros: Extremely high capacity for large trailers; Safety lock adds peace of mind
Cons: Very heavy and bulky, difficult to install solo; Premium price tag

6. Ultra-Fab Products 12V Electric Trailer Jack: Compact Design

🛒  Check Price on Amazon →

The Ultra-Fab Products jack is designed for compactness and portability, making it a good fit for small utility trailers and lightweight campers. In our research, owners appreciated its easy installation and the convenience of a lightweight unit that doesn’t add much tongue weight. The 10 inch stroke is adequate for basic leveling.

However, the 2000 lb. capacity and aluminum construction mean it’s not suitable for heavy-duty use. Some users reported that the motor struggles with loads near its limit and that the aluminum housing can be prone to dents if mishandled. If you have a small trailer and value weight savings, this is a decent option. For anything heavier, choose a steel model with higher capacity.

• Lightweight aluminum construction for easy handling
• Compact 10 inch stroke fits small trailers
• Quick-connect wiring harness for fast installation

Pros: Very lightweight and portable; Good for small utility trailers
Cons: Low capacity limits use to light loads; Aluminum may dent more easily than steel

7. Buyers Products Electric Trailer Jack 12V: Budget Pick

🛒  Check Price on Amazon →

The Buyers Products electric jack is our budget pick, offering a no-frills solution for those who want electric convenience without spending much. Based on owner feedback, it performs adequately for light trailers but has noticeable limitations. The steel housing is painted rather than coated, which may lead to rust over time in wet conditions.

We found that the motor is slower and louder than more expensive models, and some users reported failure after a few seasons of heavy use. This jack is best for occasional use on small trailers where budget is the primary concern. If you need reliable performance for frequent towing or in harsh environments, we recommend investing in a higher-quality option.

• Entry-level electric jack at a low price point
• Standard 12 inch stroke for most trailers
• Basic steel housing with paint finish

Pros: Affordable entry into electric jacks; Works for basic needs
Cons: Less durable than premium options; Motor can be slow and noisy

Frequently Asked Questions

What is an automatic trailer jack and how does it work?

An automatic trailer jack, also known as an electric trailer jack, uses a 12V DC motor to raise and lower the trailer tongue instead of manual cranking. It typically mounts on the trailer tongue and connects to the trailer’s battery or tow vehicle’s electrical system. A switch controls the up/down motion, making it easier to hitch and unhitch trailers.

How do I choose the right capacity for my trailer?

You need a jack with a capacity that exceeds your trailer’s tongue weight. Tongue weight is typically 10-15% of the total loaded trailer weight. For example, a 5000 lb. trailer has a tongue weight of 500-750 lbs., so a 2500 lb. capacity jack is more than sufficient. Always choose a jack with a capacity at least 20% higher than your tongue weight for a safety margin.

Can I install an electric trailer jack myself?

Yes, most electric jacks are designed for DIY installation with basic tools. The process usually involves bolting the jack to the trailer tongue and connecting the wiring to the trailer’s battery or 7-pin connector. However, if you are not comfortable with electrical work, professional installation is recommended to ensure proper grounding and safety.

Are electric trailer jacks weatherproof?

Most electric jacks have some weather resistance, but the level varies. Many models feature sealed motors and corrosion-resistant coatings, but they are not fully submersible. It’s best to store the trailer with the jack retracted and avoid prolonged exposure to saltwater or heavy rain. For harsh environments, look for jacks with stainless steel components or marine-grade coatings.

What happens if the battery dies while using an electric jack?

Many electric jacks include a manual override feature, typically a crank or wrench that allows you to operate the jack manually in case of power loss. Check the product specifications to ensure it has this feature. If not, you may need to jump-start the battery or use a portable power source.

Our Verdict

After researching and comparing specifications, safety standards, and owner feedback, our top pick is the Barker 3000 lb. Electric Trailer Jack for its excellent balance of power, speed, and durability at a reasonable value. The Lippert Components 1357100 is a close runner up, offering higher capacity and a longer stroke for those who need extra lift. Choose based on your trailer’s weight and your specific needs.
