A car emergency jump starter is a portable device powered
primarily by lithium-ion batteries or lead-acid batteries, designed specifically to jump-start vehicles with dead batteries.

This product is a lithium-polymer car emergency jump starter. Compared with lead-acid battery-powered counterparts, lithium-polymer car emergency jump starters are relatively new and more popular in the market. These devices are lightweight and compact, allowing for easy one-handed operation. In addition to jump-starting cars, this product can also power a variety of electronic devices, serving as both a jump starter and a power bank. Its lighting function offers four modes—emergency lighting, SOS alarm, strobe light, and warning light—making it even more practical.
