Power Source: The jack typically operates on 12V DC power, connecting either to a car's cigarette lighter socket or directly to the vehicle's battery using the included clamps.
Operation: The lifting mechanism is automatic, often a scissor-style or hydraulic jack, and is operated by a push-button controller, eliminating manual cranking.
Contents: The case includes the electric jack unit, power cables, spare fuses, and usually a pair of gloves, as seen in the image. Many kits also include an electric impact wrench and/or a tire inflator pump.
Safety: Built-in safety features often include automatic stopping at the maximum height limit and a self-locking power structure that prevents the jack from suddenly falling in case of a power outage.
Case Functionality: The durable plastic carrying case often features a red triangle warning sign.
