About This

• 【Perfect Function: Car Battery Starter and OBD2 Detector】Why a vehicle fails to start isn't always a dead battery—it could be a sensor, alternator, or fuel system issue. This all-in-one device first identifies the root cause via OBD2 diagnostics, then provides emergency jump starting when a dead battery is confirmed. By combining a professional-grade diagnostic tool and a portable jump starter, it eliminates guesswork, unnecessary towing, and the need for two separate devices.
• 【8000mAh Portable Jump Starter for 12V Vehicles】Delivering 5000A peak current, this portable jump starter reliably starts all 12V gasoline vehicles and diesel engines up to 10.0L. When a battery is completely dead, the force start function overrides low-voltage protection to safely revive the vehicle. Three simple steps and clear clamp indicators make it accessible for first-time users while delivering professional-grade starting power. It is an essential emergency tool for every driver.
• 【Comprehensive OBD2 diagnostic capabilities】This built-in OBD2 scan tool reads and clears engine fault codes, displays live data streams with graphic support, and provides access to freeze frame data, MIL status, I/M monitor readiness, and vehicle information. It functions as a personal mechanic for both cars and trucks, allowing drivers to diagnose trouble codes and understand vehicle health before walking into an auto repair shop. Maintenance preparation becomes informed rather than reactive.
• 【4-in-1 multi-functional coverage for all scenarios】Whether for rescue operations or daily emergencies, this car starter with OBD2 can be used. Beyond jump starting and OBD2 scanning, this device integrates a portable power bank with dual fast-charge ports, a multi-mode emergency flashlight (including SOS), and real-time vehicle fault monitoring. A single compact tool handles road trip diagnostics, parking lot phone charging, dark highway emergency lighting, and daily vehicle health checks—without carrying separate equipment.
• 【Total Peace of Mind: 10-Way Ultimate Safety】Built on a high-efficiency Battery Management System (BMS), this jump starter provides 10 core safety protections including short circuit protection, over-current protection, reverse polarity protection, over-temperature protection, and over-charge protection. The smart clamps won't spark and won't send power until the connection is correct. Even if you've never jumped a car before, you can do it safely on your first try.
• 【Reliable after-sales repair service】An 18-month warranty covers this car emergency jump starter and OBD2 scanner combo. Support is available before purchase, during setup, or after extended use—with troubleshooting, replacement, or refund provided as needed. This after-sales commitment transforms a technical automotive tool into a confident, risk-free purchase for everyday drivers.
• 【Usage Notes】Correct usage requires distinguishing between the two included cables.The OBD2 diagnostic cable connects to the vehicle's OBD2 port—typically located under the steering wheel—for code reading, battery health checks, and check engine light reset. The heavy-duty clamp cable connects directly to the car battery for jump starting.
