Have you ever cranked a manual scissor jack on a dark roadside and wished for a button that does the work for you? An automatic car jack plugs into your 12V power outlet (the same one your phone charger uses) and lifts your vehicle at the push of a button. It keeps you clean and safe. This guide covers five electric 12V jacks that all lift up to 17.7 inches or close to it. The real differences are about fit, weight, and extra features like a built-in tire inflator or an impact wrench (a tool that spins lug nuts off for you).
I’m Min, founder of Gadgets Feed. This guide compares published manufacturer specs and patterns from verified customer reviews. You get each pick’s real strengths and trade-offs.
The right automatic car jack saves you time when you need it most. You just need to match the jack’s collapsed height (its lowest point) to your vehicle’s ground clearance, and decide if you also want a tire inflator or an impact wrench.

How To Choose The Best Automatic Car Jack
An automatic car jack runs on your vehicle’s 12V power, so you never break a sweat. But not every electric jack fits every car. The handful of specs that decide the fit are easy to check once you know what to look for.
Minimum Height — The Make-or-Break Number
The minimum height is the jack’s collapsed height — the lowest point it sits at when fully retracted. If your car sits low to the ground (a sports car, a lowered sedan), the jack has to slide under the frame before it starts lifting. Most electric jacks sit between 5.9 and 6.1 inches at rest. The ROGTZ drops to 2.32 inches — a 2.6x gap versus that typical height, which makes it the only pick for very low-clearance vehicles.
Capacity — Tons vs. Your Actual Vehicle Weight
The load capacity (measured in tons) tells you the heaviest vehicle the jack can safely lift. Most jacks here are rated for 5 tons, which covers full-size SUVs and light trucks. The Greenworks 24V cordless jack is the outlier at 3 tons — fine for sedans and crossovers, but not an option if you drive a heavy pickup. Never buy a jack rated below the gross weight of the vehicle you actually own.
Extra Tools — Inflator, Impact Wrench, and Lights
Many automatic car jacks double as emergency kits. A built-in tire inflator (like the 35L/min pump on the Trihelper) saves you from carrying a separate air compressor. An electric impact wrench (included with the KACOLA model, with 480 N.m max torque) speeds up removing lug nuts. LED work lights (small lights that shine on the work area) make nighttime changes safer. Decide whether these extras are worth the extra weight in your trunk.

In‑Depth Reviews
1. Electric Car Jack (KACOLA) — 5 Ton 12V Digital Display
The all-in-one electric jack that brings its own impact wrench and digital tire gauge.
You do not need a separate tool to loosen lug nuts with this jack. It includes an electric impact wrench (a motorized tool that spins nuts off) with max torque of 480 N.m (about 354 foot-pounds, enough for stubborn bolts on most cars). The built-in tire pressure display (a digital screen on the inflator) lets you see the PSI as you fill. Four LED lamp beads (bright work lights) light up dark workspaces. It lifts from 6.1 to 17.7 inches — a 5-ton load capacity that handles sedans, SUVs, and light trucks. Buyers report the impact driver loosens lug nuts quickly and the air compressor has adjustable output with an auto shut-off. One reviewer noted it worked perfectly on a 4,445 lb Lincoln Towncar.
The minimum height of 6.1 inches is about average for this category. A buyer warned it may not fit under very low sports cars or small sedans. The dual power feed modes mean you can plug into the 12V cigarette lighter or connect directly to the battery terminals, which keeps it running even when the car is off.
Why it’s great
- Includes electric impact wrench with 480 N.m max torque — loosens lug nuts with one hand
- Digital tire pressure display for precise inflation
- Dual power feed modes (cigarette lighter or battery terminals)
Good to know
- At 19.3 pounds it weighs 7.3 pounds more than the ROGTZ
- 6.1-inch minimum height may not clear some low sports cars
Best for: Drivers who want a complete roadside rescue kit — lift, wrench, and inflator in one box.
Skip if: You drive a lowered sports car and need a jack with a lower collapsed height.
2. Trihelper Electric Car Jack — 5 Ton 12V Floor Jack
A compact floor jack that also inflates tires and fits a pontoon trailer lift.
You get both a lift and an air compressor in one package with this 13.6-pound Trihelper. The built-in air compressor inflates tires at 35L/min (liters per minute) — owners mention it fills a standard tire in about 2 minutes. Its load capacity is 5 tons, and it raises up to a maximum of 17.7 inches in about 1 minute. One buyer mentioned using it to lift a pontoon trailer with the boat on it to fix a burnt-out axle bearing, calling it better than a manual jack. That versatility makes it a smarter value than the pricier STANDTALL for buyers who want the inflator feature.
The stored unit’s dimensions are 3.6 x 2.7 x 5.2 inches — note that is the footprint of the stored unit, not the lifting range. The minimum height is 5.9 inches, which is typical for this category. Customers note that a silver connector inside the cord can stick in the jack due to weak prongs, though one buyer replaced the defective connector for cheap. The inclusion of a safety hammer and sockets adds to the emergency kit value.
The case for it: Compact at 13.6 pounds and under 5.2 inches in its smallest dimension, with a 5-ton capacity that lifts almost any passenger vehicle or small trailer.
The catch: The connector prongs on the power cord have been flagged as fragile by buyers — check and reinforce before a real emergency.
Best for: Someone who wants a versatile roadside kit with an inflator for under 14 pounds.
Skip if: You expect a power cord connection that will never need a DIY fix.
3. STANDTALL Electric Car Jack — 5 Ton 12V Portable
A smooth-lifting 5-ton jack that buyers trust on a 2024 Outback without blowing fuses.
The STANDTALL jack uses a 12V electric hydraulic system (a motor powers hydraulic fluid to push the ram up) for fast, stable lifting up to a maximum of 17.7 inches. It has a 5-ton load capacity and weighs 13.4 pounds. The built-in air compressor and LED work light make it ready for roadside emergencies. One verified reviewer said it works flawlessly on a 2024 Outback using the interior 12V socket without blowing fuses, calling it the best and easiest jack bought.
Buyers also note that the jack lifts higher than a bottle jack (a tall, single-point jack) and handles a hybrid SUV smoothly. Two watch-outs: the air pump gauge is accurate but the light is weak, and one reviewer warned that the top screw extension has no stop — they recommend painting 2 inches of threads red to prevent the screw from dislodging and dropping the vehicle. Always use jack stands (metal supports that lock in place) as backup, not just the jack alone.
The case for it: Proven reliability across multiple vehicle types (sedans, SUVs) with smooth power up and down — one buyer on a 2024 Outback confirmed zero blown fuses on the 12V socket.
The downside: The LED light is dim and the top screw extension lacks a built-in mechanical stop, so a DIY thread-marking mod is recommended for safety.
Best for: Everyday drivers who want a dependable, easy-to-use jack that works with a standard 12V outlet.
Skip if: You need a bright integrated work light or prefer a design that does not require a manual thread mod.
4. ROGTZ Electric Hydraulic Car Jack — 5 Ton 12V Portable
The only electric jack in this list slim enough to slide under a 2.32-inch clearance.
With a minimum height of 2.32 inches, the ROGTZ sits 2.6 times lower than the typical 6.1-inch minimum of other jacks like the KACOLA. That makes it the only choice here for vehicles with very low ground clearance. It lifts to 17.7 inches with a 5-ton load capacity, and it weighs just 12 pounds — the lightest among the 5-ton jacks reviewed. A buyer commented that it lifts an SUV smoothly and easily and feels sturdy and reliable.
The trade-off is speed: one owner reported that the jack operates very slow, which is fine for a single tire change but frustrating if you are rotating tires and need to lift the car multiple times. The kit includes a pressure relief wrench (a tool to release hydraulic pressure), LED and warning lights, and is CE certified (tested to withstand 1000 lift cycles). A 12-month warranty backs the unit.
Why it’s great
- 2.32-inch minimum height — fits under low-clearance sedans and sports cars
- At 12 pounds it is the lightest 5-ton jack in the lineup
- CE certified with 1000-cycle lift testing and 12-month warranty
Good to know
- Reviewers point out it operates very slow compared to competing electric jacks
- Not ideal for multi-tire rotations; best for single emergency changes
Best for: Owners of low-clearance cars who cannot fit a standard 6-inch jack under the frame.
Skip if: You need a fast lift for rotating tires or working on several axles in a row.
5. Greenworks 24V Cordless Car Jack Kit — 3 Ton Max
A cordless jack that runs on the same battery as Greenworks 125+ outdoor tools.
Skip the 12V cigarette plug entirely with this jack. It uses a 24V 2Ah battery and charger that come in the box — no cables or battery clamps needed. The load capacity is 3 tons (max loading for vehicle weigh) with a jacking force of 1.55 tons. The lifting height is 6-1/8 to 17-1/2 inches — fine for sedans and SUVs under 3 tons. At 11.5 pounds, it is the lightest jack in this review and the most compact to store at 11.8 x 5.3 x 5.9 inches.
A one-button lift operation controls the jack, and built-in LEDs plus orange flashing lights illuminate the work area. One buyer praised it as excellent value versus a scissor jack, with easy push-button operation. Another mentioned the ram raises and lowers slowly but not excessively. Note that the 3-ton capacity is lower than the 5-ton jacks above (like the KACOLA and STANDTALL), so it will not handle a heavy pickup. The self-locking structure and overload protection are always recommended alongside jack stands.
Why it’s great
- Fully cordless — uses included 24V 2Ah battery and charger, no car connection needed
- At 11.5 pounds it is the lightest and most compact jack in the review
- Part of the Greenworks PowerAll family; battery works across 125+ tools
Good to know
- 3-ton load capacity is lower than the 5-ton competition — not for heavy trucks
- Shoppers say the lift is slow, and the jack is less stable than traditional models (use jack stands)
Best for: Greenworks tool owners or anyone who wants a cable-free jack for sedans and crossovers.
Skip if: You drive a truck or large SUV that needs more than 3 tons of lift capacity.
Understanding the Specs
Minimum Height (Collapsed Height)
This is the lowest point the jack sits at when it is fully retracted. It matters because the jack has to slide under your vehicle’s frame before it can start lifting. Standard sedans typically have enough clearance for a 5.9- to 6.1-inch minimum, but lowered sports cars or performance sedans may need a jack as low as 2.32 inches (like the ROGTZ). If the minimum height is too tall, the jack simply will not fit.
Load Capacity (Tons)
The load capacity tells you the heaviest vehicle the jack can safely lift. Most automatic jacks are rated at 5 tons, which covers heavy SUVs, light trucks, and full-size sedans. The Greenworks model is rated at 3 tons — adequate for most cars and crossovers, but never enough for a heavy pickup. Always pick a jack with a capacity that matches or exceeds your vehicle’s gross weight, and always supplement with jack stands for safety.

Final Thoughts: The Verdict
For most people, the automatic car jack winner is the Electric Car Jack (KACOLA) because it packs an impact wrench, a digital tire inflator, and a bright LED light into one kit — everything you need for a roadside change in a single box. If you want a lightweight cordless option that works with an existing tool battery, grab the Greenworks 24V Cordless Car Jack. And for low-clearance vehicles that nothing else fits under, the standout is the ROGTZ Electric Hydraulic Car Jack with its 2.32-inch minimum height.
