Emergency Car Starter Power Jumper JQ256300Q
Heavy-Duty Performance Without Compromise
To meet the high-power starting demands of heavy-duty vehicles such as heavy trucks, construction machinery, and large RVs, ordinary starter power supplies are often insufficient. The emergency car starter power jumper stands out with its superior performance. A 25.6V rated voltage, combined with 3.2V/300Ah high-capacity lithium iron phosphate battery cells, provides a robust 7.68 kWh rated energy reserve. Even when faced with large-displacement diesel engines or heavily discharged heavy-duty vehicles, the emergency car starter power jumper can instantly deliver powerful output, ensuring a high single-start success rate. It effectively avoids repeated starting failures caused by insufficient power, making it a core emergency solution for logistics fleets, engineering teams, and outdoor rescue operations.
