Features

  •  【Smart Jump Starter and Battery Tester】A powerful jump starter that delivers up to 2500A peak current to start 12V vehicles (up to 8.5L gas / 6.5L diesel). It functions as both a car battery booster and battery tester, featuring built-in Bluetooth 5.3 for real-time battery monitoring via a mobile app. It supports battery health, cranking, and charging tests, as well as real-time voltage monitoring, and then provides key data such as SOH (State of Health), SOC (State of Charge), voltage, current, and rated capacity.
  • 【Extreme Safety Protection】Equipped with an advanced BMS and smart self-identifying clamps for fully insulated and reliable operation. Features 10 comprehensive protections, including Spark-Proof, Reverse Polarity, Over-Charge, Over-Current, Short-Circuit, Low/High Temperature, Over-Voltage, and Over-Load protection—ensuring safe and confident use.
  • 【Wide Battery Compatibility】This alternator tester is compatible with most batteries (100–2000 CCA), including Flooded, AGM Flat Plate, AGM Spiral, GEL, and EFB types. Supports multiple testing standards: CCA / SAE / EN / DIN / IEC, ideal for DIY users, home mechanics, and vehicle owners.
  • 【Portable Power Bank & Emergency LED Light】With USB-A and USB-C two-way charging ports, it keeps your smartphones, tablets, and more fully powered on the go. The built-in LED flashlight offers 6 modes (100%, 50%, 10%, Blink, SOS, and Strobe), making it a reliable and must-have emergency companion for road trips, camping, and outdoor adventures.
  • 【ConnectMax Technology for Faster Starts】Automatically detects the connection impedance between clamps and battery, optimizing power delivery and improving the success rate of vehicle starting, even in challenging conditions.
