The AstroAI S8 Pro is a powerful 12V cordless car jump starter capable of delivering up to 3,000A peak current and 500 cold cranking amps. According to the manufacturer, it can effectively jump start engines up to 9L gasoline or 6L diesel capacity. Thanks to its large 12,000mAh lithium (NMC) battery, this compact device provides multiple jump starts before needing to be recharged. Unlike traditional lead-acid batteries, the lithium battery retains up to 80% of its charge even after two years of storage without use.
In addition to jump starting vehicles, the S8 Pro functions as a portable power bank, allowing you to recharge smartphones or other USB-powered devices in emergencies. It supports fast charging via USB Type-C, and a USB Type-A to USB Type-C cable is included in the package for added convenience. The unit also features a built-in LED flashlight with three modes—standard light, SOS signal, and strobe—for improved visibility during nighttime breakdowns or urgent situations.
Despite its robust performance capabilities, the S8 Pro remains compact and lightweight, weighing in at just 1.5 pounds. Its sleek design makes it easy to store in your glove compartment, center console, or trunk for quick access whenever needed.
