SMART JERRY Gas Transfer Pump, Cordless 3.5 GPM Fuel Pump with Auto-Stop

A cordless design makes fuel transfers easier in the garage, at the dock, or beside equipment away from a wall outlet. The SMART JERRY Gas Transfer Pump delivers flow rates of up to 3.5 GPM and stops automatically when liquid reaches the nozzle sensor. Four adapters help match the pump to a range of common fuel containers.

What stands out

The pump offers two power options for different jobs: use four AA batteries for cordless operation, or connect the included USB-C cable to a compatible power source for extended use. It can also operate on two AA batteries in an emergency. AA batteries are not included.

An automatic nozzle sensor stops the flow and sounds an alarm when liquid reaches the sensor. That feature helps manage filling and reduce the chance of an overflow. The 6.5-foot hose provides reach between a fuel can and the equipment being filled, while a single on/off button keeps operation straightforward.

The essentials

This portable transfer pump is designed for gasoline, diesel, kerosene, and oil. Its four gas can adapters are sized at 2, 2.1, 2.75, and 3.75 inches, giving you options for matching common fuel cans, utility jugs, and equipment tanks. The listed vehicle applications include cars, trucks, motorcycles, ATVs, UTVs, RVs, tractors, buses, and snowmobiles.

The kit includes the transfer pump, four gas can adapters, a storage bag, a USB-C cable, and a user manual. Materials listed for the pump include PE, POM, PVC, and polypropylene. At 700 g, the pump is portable for moving between a garage, work area, or outdoor refueling spot.

Compared with a manual siphon pump, this battery-operated design uses a powered flow and an automatic stop sensor rather than relying on hand pumping. That makes it a practical fit for routine transfers where a compatible can and a nearby power option are available. The 3.5 GPM maximum flow rate is useful when you want to move fuel without operating a manual pump.

How to use it

Connect the hose and select an adapter that fits the fuel container. Power the pump with AA batteries or the included USB-C cable connected to a power source, then use the on/off button to begin the transfer. Keep the nozzle sensor positioned where it can detect the rising liquid, the pump stops and sounds an alarm when the liquid reaches it. After use, return the components to the included storage bag.

Questions before you buy

What power sources can I use? The pump runs on four AA batteries, can operate on two AA batteries in an emergency, or can connect to a USB-C power source using the included cable. AA batteries are not included.

Which containers can the adapters fit? Four adapters are included, with listed diameters of 2, 2.1, 2.75, and 3.75 inches. They are intended for common fuel cans and utility containers, choose the adapter that matches the container opening.

What does the auto-stop feature do? A sensor in the nozzle detects when liquid reaches it, then stops the flow and sounds an audible alarm. This helps manage filling and avoid overflows.

Is it worth it?

Worth considering if you want a portable powered pump for transferring gasoline, diesel, kerosene, or oil between compatible containers and equipment. Its combination of USB-C or battery power, a 6.5-foot hose, four adapters, and sensor-based auto-stop makes it especially useful for refueling tasks across a garage, yard, or roadside work area.
