3. COMPACT AND PORTABLE: Weighing only 329g, this compact car jump starter power pack is a must-have for practical car accessories. It’s easy to carry and store anywhere, even in tight spaces, making it an excellent tool for both outdoor activities and emergency situations
4. EASY TO JUMPSTART: Insert smart battery clamps fully into the jump starter powe pack. Connect red clamp to battery positive (+), black to negative (-). Operate the jump starter by clamp indicators: Green light: Connection correct, safe to use; Red light + beep: Reverse connection. Reconnect terminals correctly. When clamp indicator is green, jump-start the car. After successful jump-start, disconnect the clamps
5. 5-IN-1 MULTIFUNCTIONAL: Beyond a battery jump starter power pack, it works as a portable power bank for your devices. The built-in LED delivers 3 practical modes: steady work light for roadside repairs, SOS for signaling help, and strobe for hazard warning—keeping you safe and visible in any emergency
6. FULL SET OF ACCESSORIES: This package comes complete with B8 jump starter powe pack, smart battery clamps, a USB-A-C cable, a user manual, and a storage bag
7. WARM TIPS: Turn off all vehicle devices before jump-starting. If the engine doesn't start within 5 seconds, stop and remove the cables immediately. Do not leave the smart clamp plugged into the EC5 port (it drains power even when the vehicle is off). Do not use EC5-to-cigarette-lighter or any EC5 adapters to power dashcams or other devices – this will drain the battery to 0V and make it unchargeable. Use a 5V/2A charger (original cable preferred). Charge at 0–45°C. Recharge when battery is at 1–2 bars to prevent deep discharge. For best battery health, top up every 3 months
