Be ready for any roadside moment with a jump starter designed for quick, dependable backup.

The jump starter delivers strong performance in a portable size, making it easy to store in your glovebox or trunk. Its durable build supports everyday drivers, travelers, and anyone who wants greater control over emergency situations.

Its 12V output is designed for gasoline and diesel engines commonly found in cars, SUVs, and small trucks. With a high peak current, it provides the burst of power required to start engines that struggle due to low battery levels or cold temperatures.

The built‑in USB port offers practical convenience for powering phones or tablets when no outlet is available. While it is not intended to replace your everyday charger, it gives you essential support when you're away from home.

The flashlight function is particularly helpful when working in dim environments. Whether you’re attaching clamps at night or navigating a dark roadside area, the illumination helps you work quickly and safely.

To get the most from this device, charge it fully before first use and top it up roughly every three months. Lithium batteries naturally behave differently at low percentages, so faster charge and discharge rates near the end of the power cycle are normal.

It supports engines up to 6.0L for gasoline and 5.0L for diesel, covering most daily vehicles. The wide operating temperature range ensures performance in both hot summers and freezing winters.

The package includes the jump starter unit, clamps, a USB‑to‑Type‑C cable, and an English user guide to help you get started right away.

Whether preparing for long road trips or protecting yourself from battery failures, this jump starter adds convenience and reassurance to everyday driving.
