A compact 12V DC electric fuel transfer pump ideal for transferring gasoline, diesel, or kerosene from cans, barrels, or vehicles to equipment, generators, boats, tractors, or storage tanks. Powered directly by a 12-volt battery (car, truck, or portable), it delivers a practical flow rate (typically 20–50 L/min depending on model) for quick refueling without manual siphoning or gravity feed. The built-in auto-stop sensor automatically detects when the receiving tank is full and shuts off the pump to prevent overfilling, spills, fuel waste, and potential fire hazards. Includes a durable hose (often 2–4 meters), ergonomic manual nozzle with trigger lock, inlet filter to catch debris, and secure battery clips or cigarette lighter adapter for easy connection. Features thermal overload protection, anti-static components, and rugged construction for safe, reliable use in garages, farms, construction sites, or roadside emergencies. Portable with carry handle, simple operation, and low maintenance—perfect for safe, efficient fuel handling anytime, anywhere.
