Product Details
- ULTRA POWERFUL JUMP STARTING: The S8 Ultra jump starter delivers a powerful 4000A peak current and 45C discharge rate. This superior power reliably jump-starts all gas and up to 12L diesel engines, even when the battery is fully drained.
- EASY TO USE: This car jump starter includes smart jumper cables with intuitive indicators, providing a safe and seamless user experience. The car starter automatically analyzes the battery’s voltage to deliver the appropriate boost. For batteries at 9-12 V, it will automatically jumpstart them after the jumper cable is connected. When the batteries are below 9 V, the S8 Ultra will prompt you to press the Boost Button, quickly jump starting fully-drained batteries.
- SUPERSAFE 12V JUMP BOX: The S8 Ultra car battery jump starter provides 10 comprehensive safeties, including reverse polarity, overcurrent, reverse connection, overvoltage, overcharge, overdischarge, overload, short circuit, low/high-temperature protection, and spark-resistance. It is also waterproof (IP 65), dust-proof, and drop-proof.
- WIDE COMPATIBILITY PORTABLE CHARGER: Featuring multiple ports, this jump starter doubles as a powerful portable charger for your devices. Keep your phones, tablets, and drones powered on the road with the S8 Ultra. (Wall charger not included.)
- CAREFULLY-CRAFTED DESIGNS: This jump starter is precision-engineered to make vehicle recovery both safe and efficient. Its intuitive battery indicators simplify operation, while high-grade internal components guarantee powerful, reliable performance every time.
- ROADSIDE CAR EMERGENCY KIT: The AstroAI S8 Ultra portable car jump starter can pack a punch, reviving cars in less than a minute, using as a safe and reliable tool to help you take risks. A built-in integrated flashlight can makes nighttime operation easy with its 3 light modes.
