MISFANS Fuel Transfer Pump 3.8 GPM Cordless with Auto-Stop Sensor, USB-C or 4xAA Power, 51" Hose

This compact transfer pump replaces lifting heavy gas cans and guessing when a tank is full. Designed for gasoline, diesel, kerosene and non-potable water, the MISFANS unit combines a high-speed 3.8 gallons-per-minute flow, a built-in auto-stop sensor to prevent overflows, and simple one-touch controls. It runs on four AA batteries or via USB-C power for flexible use at the garage, campsite, or roadside.

How does the auto-stop sensor prevent spills?

The pump incorporates a high-sensitivity sensor inside the nozzle that detects backflow when the receiving tank reaches capacity and instantly cuts power to stop the flow. That automatic shutoff reduces splashes, fumes, and cleanup time compared with manual transfer methods. The design works with a wide range of vented plastic fuel cans common in North America.

• High-sensitivity sensor stops flow immediately when level rises
• Leak-proof nozzle and secure clip keep the discharge steady
• Clear, transparent intake hose lets you watch fuel flow
• Reduces spills, odors, and cleanup work

How fast and efficient is the 3.8 GPM flow?

At 3.8 gallons per minute (about 14.5 LPM) this MISFANS pump moves fuel roughly 20% faster than many common 2.4–3.2 GPM models. Faster flow shortens fill time for lawn mowers, generators, motorcycles, and small equipment, so chores finish sooner without repeated lifting. The longer 51" discharge hose and 19" intake hose make it easy to reach awkward tank locations.

• 3.8 GPM high-speed transfer cuts refueling time
• 51" discharge hose for extended reach and flexibility
• 19" intake hose fits most can outlet positions
• Transparent hose helps spot air pockets and flow rate

What power options and controls does it offer?

MISFANS built dual power choices into the pump: it accepts four AA batteries for full cordless portability or runs continuously via the included USB-C cable connected to a power bank. Controls are one-touch—an independent start/stop button eliminates confusing switches so anyone can operate it safely. The lightweight ABS housing and nozzle clip make storage and handling straightforward.

• Runs on 4 AA batteries for true cordless use
• USB-C input for power bank or vehicle adapter (cable included)
• Simple one-touch button for start/stop and emergency stop
• Durable ABS shell and kink-resistant PE hose for longevity

Which adapters and fuels are supported?

The kit contains four different adapters to fit a broad range of North American plastic gas cans, including racing jugs and vented spouts. It is suitable for gasoline, diesel, kerosene, and non-potable water transfers; avoid using with potable water or corrosive chemicals. A nozzle clip and drawstring storage bag are included to minimize drips and keep the pump protected between uses.

• Four adapters for common can spouts and neck sizes
• Compatible with gasoline, diesel, kerosene, non-potable water
• Nozzle clip prevents drips; storage bag included
• Not recommended for drinking water or corrosive liquids
