BYERNAUTO Cordless Fuel Transfer Pump 3.2 GPM — Battery-Powered with Auto-Stop Sensor

The BYERNAUTO Automatic Fuel Transfer Pump is a cordless, battery-powered gas can pump that delivers up to 3.2 GPM with an auto-stop sensor and four adapters for fast, spill-reducing refueling.

This compact electric transfer pump was designed to make moving gasoline, diesel, kerosene, water, or light oils from cans to tanks safer and easier without lifting heavy containers or wrestling with funnels. It runs on AA batteries for true portability, includes multiple nozzle sizes to match most fuel cans, and uses a weather- and corrosion-resistant hose so it stands up to outdoor use.

How fast will it refill my tank?

The pump moves liquid at a maximum rate of 3.2 gallons per minute, so it refills small tanks and jerry cans quickly while keeping flow steady to reduce splashing. Actual speed depends on liquid viscosity and how well the nozzle fits the inlet.

• Peak flow: 3.2 GPM for rapid transfers
• Smooth, continuous delivery for controlled pouring
• Suitable for gasoline, diesel, kerosene, and light oils

Does the unit prevent overfilling and spills?

Yes—the pump includes an auto-stop sensor that detects when the receiving tank is full and automatically stops pumping to limit overflow. An LED indicator shows when the pump is active, and the design aims to reduce manual monitoring.

• Auto-stop sensor interrupts flow at tank-full
• LED on/off indicator for pump status
• Avoids waste and keeps work areas cleaner

What power does it use and how portable is it?

The BYERNAUTO pump is cordless and runs on four AA batteries for convenient, cable-free use at the garage, campsite, or on the road. In low-power situations it can operate on just two AA cells for emergency transfers, making it highly portable and practical where outlet power isn’t available.

• Powers with 4 x AA batteries (not included)
• Emergency operation on 2 x AA batteries
• Lightweight, easy to carry for field or home use

Will it fit my gas can and is it durable?

The kit ships with four adapters — a fixed 1.3-inch plus removable 1.9-, 2.3-, and 2.5-inch fittings — to match most common can openings. The hose resists weather and corrosion while the motor includes explosion-proof and overload-protection features for safer operation.

• Four adapter sizes for broad compatibility
• Weather- and corrosion-resistant hose material
• Explosion-proof motor and overload protection for safety

Who is this for: BYERNAUTO’s cordless fuel transfer pump is built for RV owners, boaters, landscapers, fleet operators, and anyone who regularly moves small volumes of fuel and wants a safer, easier alternative to pouring. It’s also handy for outdoor hobbyists, mechanics, and homeowners who need a portable, spill-minimizing pump for gasoline, diesel, kerosene, or light oils.

Usage tips: Submerge the pump inlet before starting to avoid dry running, keep the auto-stop sensor clean so it functions correctly, and remove batteries when storing the unit for long periods. Note: the pictured fuel tank is not included with the pump.
