The S4000 jump starter features a dual USB fast output design (5V/3A & 5V/2.4A) to quickly charge various USB devices, and a 3.4-inch LCD smart display that clearly shows the operation status, power level, and possible errors in real-time. The user-friendly design includes a 400-lumen bright LED light with 3 modes (flashlight/strobe/SOS) for different emergency situations, and a red SOS mode that works as a warning triangle.

The S4000 portable jump starter has 10 advanced safety protections to ensure 100% safe use, and can quickly and safely start a dead car battery even in extreme temperatures (-4°F~140°F). The package includes a car jump starter, jumper cable, charging cable, EVA carrying case, 15W wall charger, and user manual, with 2 years of product quality maintenance.

Users are advised to keep the battery starter power above 50% for better startup efficiency, not mistake the protective film on the screen for scratches, and recharge the jump starter once every three months if it's not used for a long time. When using the "ready" function, users need to press and hold it for 4 seconds.
