Portable Jump Starter for Cars up to 6.0L Gas & 3.0L Diesel Engines

Reliable tools are a must, whether you're off-roading or road-tripping. To protect our trips against dead batteries, we designed the AstroAI S8 Jump Starter. This jump starter features 45 C high-rate core technology that packs a punch, reviving most cars in less than a minute. To maximize user safety, we integrated 8 comprehensive safeguards, creating a safe and reliable tool to help you take risks, push the envelope, and enjoy all of life's adventures.

The AstroAI S8 Jump Starter boasts a powerful 1500 A peak current, quickly starting low-voltage and fully-drained batteries. The car jumper starter portable pack has a 45 C high-rate lithium battery that can start 6.0 L gas/3.0 L diesel engines and other 12 V vehicles like motorcycles, cars, SUVs, pickups, or lawnmowers. The smart boost mode automatically detects the battery's voltage, and when it's less than 9 V, the indicator flashes green, unlocking the "BOOST" button to start fully-drained batteries.

The safety metal clamps and smart jumper cable of the S8 Car Battery Jump Starter better protect it from excessive heat damage, loose ports, battery bulging, battery expansion, and more. This portable battery jumper starter has 8 integrated protections, including reverse polarity, reverse connection, overcurrent, overvoltage, overload, overcharge, over discharge, and short circuit protection, ensuring a safe and smooth trip.
