The UltraSafe 1600A is a lithium-ion jump starter pack that lets you boost a dead 12V battery without a second vehicle. It claims 1600A peak current, enough for gas engines up to 6.0L and diesels up to 3.0L, with up to 20 jumps per charge. Spark-proof clamps and reverse-polarity protection cut the two biggest jump-starting risks, and the housing is water-resistant. It suits drivers who want a self-contained booster for cars, trucks, bikes or boats, and it competes with other compact 1000–2000A packs on safety electronics rather than raw output.

The UltraSafe 1600A is a portable lithium jump starter that lets you start a 12V vehicle with a dead battery without a second car. It has 1600A of peak current and is rated for gasoline engines up to 6.0L and diesel engines up to 3.0L. It can start cars, SUVs, trucks, vans, motorcycles, boats, and ATVs, and gives up to 20 jump starts on a single charge.
Spark-proof technology and reverse polarity protection are built in. If the clamps are connected backwards, the unit beeps and blocks current flow. The housing is water-resistant, which protects the internal battery and electronics in rain, snow, and damp or dusty places.
To use it, attach the red clamp to the positive (+) battery terminal. Attach the black clamp to the negative (-) terminal and wait for the green indicator light. Then start the engine and disconnect the clamps.
