The Autowit 12V Batteryless Jump Starter uses advanced supercapacitor technology to store energy quickly from a nearly dead car battery or other power sources and then deliver an instant, high-current burst to start the engine. Unlike traditional battery jump starters, it doesn’t rely on an internal battery, eliminating the need for pre-charging and ensuring reliable performance even in extreme temperatures.

How Does the Jump Starter Draw Power?

The device connects to the weak vehicle battery via clamps and rapidly charges its internal supercapacitors by drawing the remaining energy from the battery. This charging typically takes around three minutes, during which energy is safely accumulated.

What Is the Role of Supercapacitors in the Jump Starter?

Supercapacitors store large amounts of electrical energy and release it very quickly. With high power density, they provide the required 800 cranking amps in a short burst, sufficient to turn over gas engines up to 7 liters and diesel engines up to 4 liters.

Why Is No Pre-Charging Needed?

Since the device charges using the residual power from the vehicle’s battery or external sources like a power bank or cigarette lighter, it removes the inconvenience of charging it beforehand, ensuring it is ready to use on demand.

How Does the Jump Starter Perform in Extreme Weather?

The Autowit SuperCap 2 operates effectively in temperatures as low as -40℃ (-40℉) and as high as 70℃ (158℉), outperforming traditional jump starters that can fail in harsh climates.

What Are the Maintenance and Longevity Benefits?

Supercapacitors provide maintenance-free operation with a lifespan exceeding 20 years and over 100,000 charge cycles, far surpassing typical lithium-ion battery jump starters that need replacement every 2-4 years.

When Can Alternative Power Sources Be Used?

If the vehicle battery is too depleted, the jump starter can also be charged via alternative means such as a USB power bank or a cigarette lighter adapter, adding flexibility in emergency situations.

Where Are the Clamp Connections Located?

The jump starter houses the clamps within an integrated compartment for easy access. The red clamp attaches to the positive battery terminal (+), and the black clamp connects to the negative terminal (-).

Can It Help Powered Devices Beyond Jump Starting?

While primarily for jump starting, some EC5-compatible models and accessories can provide 12V power output suitable for running other small electronic devices.
