A Comprehensive Guide to the 12-Volt Electric Car Jack and Tool Kit

You have arrived at this article after watching a video demonstrating a modern solution to a timeless automotive problem.

The video’s narrator set the stage perfectly: “Changing a flat tire with manual tools is physically difficult and slow.” Anyone who has been stranded on the shoulder of a road, struggling with a flimsy scissor jack or trying to break the torque on a stubborn lug nut, knows this fact all too well.

The video then showcased a “12-volt electric car jack and tool kit”—a single, compact case offering a complete, powered solution. You clicked “READ MORE” to get the full story, and this article provides that detailed breakdown. We will analyze every component and function shown in the video, from the all-in-one jack to the powered wrench, to explain how this kit provides a “powered solution for roadside emergencies.”

The Problem: Why Manual Tire Changes are “Difficult and Slow”

Before exploring the solution, it’s important to understand the problem it solves. The manual tool kit included with most cars is a last resort, designed for minimal cost and weight, not ease of use.

Physical Difficulty: The standard-issue scissor jack requires significant physical effort. The user must repeatedly crank a small lever, often in an awkward, hunched position, just to get the car off the ground. The manual lug wrench, or tire iron, requires immense torque. For many drivers, breaking the “stuck” seal on lug nuts that were machine-tightened is physically impossible.
Slowness and Instability: The entire process is slow. It takes time to assemble the jack, position it, and perform the dozens of cranks required to lift the vehicle. All the while, the car is perched on a small, often unstable point, as the driver exerts force on the wheels.
The Scenario: The video sets this scene perfectly: a white sedan on the side of an asphalt road with a visibly flat tire. This is the exact “roadside emergency” the narrator mentions, a “common occurrence on the extensive American” road network, and it’s a situation that is both stressful and physically demanding.

Unboxing the “Powered Solution”

The first thing the video shows after the flat tire is the kit itself. It is a robust, black, hard-shell plastic case. This case is a key feature:

All-in-One Storage: It keeps all components organized and protected in the trunk of a car. The video shows a molded interior where each piece—the jack, the wrench, the sockets, and the power cord—has its own specific slot.
Built-in Safety: The exterior of the case itself is molded with a large, red, reflective warning triangle. This is an ingenious piece of design, allowing the case to double as a roadside safety marker to alert other drivers, a critical first step in any roadside stop.

The user simply opens the case to access the entire suite of tools needed for the job, starting with the main unit.

Component 1: The 3-in-1 Electric Jack (The “Milltoz” Unit)

The star of the kit is the multi-functional electric jack, branded “Milltoz” in the video. The narrator explains it’s powered by the car’s 12-volt outlet, and the video demonstrates its three primary functions, all consolidated into one device.

1. The Electric Motor Lift

The jack’s main purpose is to “lift the vehicle.” The user places the jack under the car’s frame (at a proper lift point) and, as seen at 0:04, adjusts the lift saddle. The video then shows the jack plugged in and raising the car (0:07-0:10) with no physical effort from the operator.

The control panel, shown clearly at 0:21, is the heart of this operation. It features:

A “JACK” switch: This switch, marked with | O ||, likely activates the jack motor.
“UP” (△) and “DOWN” (▽) buttons: These are simple, intuitive push-buttons that control the jack’s movement, allowing for precise and steady lifting and lowering.

This “electric motor” function single-handedly eliminates the “physically difficult and slow” cranking process of a manual jack.

2. The Integrated Air Compressor

The narrator also states the kit includes a “compressor to inflate the tire.” The video shows that this compressor is not a separate tool but is built directly into the body of the jack.

At 0:16, the user opens a small compartment on the side of the jack to retrieve a coiled air hose. At 0:17-0:18, they are shown screwing this hose onto the tire’s valve stem. The control panel (0:21) features an analog “Pressure gauge” (reading from 0-150 PSI) and a second switch labeled “LIGHT” (| O ||). This switch likely serves a dual purpose, activating the light and the compressor.

This is an invaluable feature, as spare tires are often under-inflated from sitting in the trunk for years. This built-in compressor ensures the spare can be inflated to the correct, safe pressure right on the spot.

3. The Built-in Flashlight

The “LIGHT” switch also controls another key feature: a built-in flashlight. At 0:00, a light is clearly visible on the front of the jack, illuminating the area under the car. This is essential for a roadside emergency, as flat tires often happen at night or in low-light conditions. It allows the user to safely and accurately position the jack on the vehicle’s lift point.

Component 2: The Electric Impact Wrench

The second major “powered” component is the electric impact wrench, which directly addresses the problem of stubborn lug nuts. The narrator calls this a “powered wrench to remove lug nuts.”

At 0:11, the video shows the user taking the handheld, pistol-grip wrench (also branded “Milltoz”) from the case, along with a socket. It presumably plugs into the same 12-volt power source.

From 0:12 to 0:15, the user is shown simply holding the wrench against the lug nuts. The tool does all the work, using its internal motor to “impact” the nut loose, a task that requires no strength from the user. This tool is also used to tighten the lug nuts back on, ensuring the wheel is secure far more easily than with a manual wrench.

Conclusion: The Complete Roadside Emergency Solution

The “electric car jack and tool kit” demonstrated in the video is a fully integrated system. It directly fulfills the promise of the “READ MORE” prompt by providing a factual look at a “powered solution” that transforms a daunting task into a manageable process.

The video walks us through the entire sequence:

A car is stranded with a flat tire.
The all-in-one kit (which doubles as a safety triangle) is opened.
The “Milltoz” 3-in-1 jack, powered by the car’s 12-volt outlet, uses its “electric motor” to “lift the vehicle” at the touch of a button.
The “powered wrench” effortlessly removes the “lug nuts.”
After the (implied) tire swap, the built-in “compressor” is used to “inflate the tire” to the correct pressure, as verified by the built-in gauge.

This kit effectively replaces three or four separate, difficult-to-use manual tools with a single, powered, and easy-to-use system. It is, as the narrator concludes, a modern and practical solution for any driver navigating the “extensive American” road system.
