MAYALEAD LLC Electric Fuel Transfer Pump — 3.8 GPM, 51" Hose, Battery/USB Powered, Auto‑Stop

The MAYALEAD Automatic Electric Fuel Transfer Pump is a portable, USB-or-battery powered gas and diesel transfer pump with smart auto-stop that moves up to 3.8 GPM through a 51" hose.

Compact and lightweight, this pump is designed to make moving fuel between cans and tanks faster and cleaner without lifting heavy containers. It combines a smart sensor, multiple power options, and four adapters to fit most North American fuel cans, giving you a versatile tool for cars, lawn equipment, generators, and emergency fuel handling.

How does the auto-stop feature prevent spills?

The built-in sensor detects when the receiving tank is nearly full and automatically pauses flow to reduce overfill and drips. This helps avoid messy cleanups and the safety risk of fuel running over tank openings. It functions whether you run the pump from batteries or USB power.

• Automatic pause when tank level reached
• Reduces risk of fuel overflow and spills
• Works consistently across gasoline, diesel, kerosene, and oil

What power options does it offer for roadside or remote use?

You can run the pump using four AA batteries for cordless operation or plug the included USB-C cable into a power bank or adapter. This dual-power flexibility means the pump is ready for roadside emergencies, remote jobsites, and situations without AC power. LED indicators show operational status so you know when the unit is powered and transferring fuel.

• Operates on 4×AA batteries (cordless portability)
• USB-C input for power banks, car chargers, or adapters
• LED status light for power and activity monitoring

Will it fit my gas cans and reach my tank?

The pump ships with four different adapters designed to fit most North American fuel can threads, and the 51" flexible hose gives you reach to fuel vehicles, mowers, ATVs, and portable generators without tilting cans. The hose and adapters simplify alignment and help prevent fumbling while pouring. A lightweight design and storage bag add convenience for transport and storage.

• Four adapters to fit a wide range of can openings
• 51" hose for convenient reach to distant tanks
• Compact 0.6 kg unit with included storage bag for portability

How fast and durable is the pump for repeated use?

The motor delivers a steady high flow up to 3.8 gallons per minute (about 12 L/min) while running quietly for user comfort. Durable ABS housing, a polyethylene hose, and quality internal components are built for repeated transfer tasks. Simple one-button operation keeps the pump intuitive for occasional and frequent users alike.

• High flow rate: up to 3.8 GPM (12 L/min)
• Quiet motor for comfortable operation
• Rugged ABS body and flexible hose for lasting use

If you regularly move gasoline, diesel, kerosene, or oil between containers and tanks and want a compact, multi-power solution that minimizes spills, this pump is a practical addition to your toolkit.
