MAYALEAD LLC Automatic Electric Fuel Transfer Pump 3.8 GPM — 51" Hose, Battery or USB Power, Auto-Stop Sensor

MAYALEAD's Automatic Electric Fuel Transfer Pump is a portable, auto-stopping 3.8 GPM pump that moves gasoline, diesel, kerosene, or oil from cans to tanks using battery or USB power.

This compact fuel transfer solution combines a smart auto-stop sensor, a long 51" hose, and four adapters to fit most North American fuel cans. Designed for roadside refueling, garage projects, and outdoor equipment, it balances high flow with quiet operation and one-button simplicity. The pump is lightweight, ships with a storage bag, and gives you cordless or USB-powered options so you can transfer fuel without heavy lifting or messy overfills.

How does the pump prevent overfilling and spills?

The unit uses an integrated sensor to detect when the receiving tank nears capacity, automatically pausing flow to reduce drips and overflow. This removes the need to watch the fill and helps keep workspaces cleaner and safer. The auto-stop feature works both when transferring fuel directly and when operating in siphon mode.

• Built-in sensor auto-pauses flow at near-full levels
• Reduces need to manually monitor fills
• Helps avoid sticky cleanups and fuel waste
• Works for gasoline, diesel, kerosene and oil

What power options are available for remote or emergency use?

You can run the pump on four AA batteries for true cordless convenience or power it via the included USB-C cable from a power bank or wall adapter. This dual-power flexibility makes the pump suitable for roadside emergencies, remote job sites, and camping where mains power isn’t available. LEDs indicate status so you know when the unit is running and when power is low.

• Operates on 4×AA batteries (cordless) for portability
• USB-C input supports power banks and adapters
• LED status light shows on/off and power conditions
• Lightweight 0.6 kg design for easy carrying and storage

Which cans and vehicles will the adapters and hose reach?

The kit includes four adapter nozzles sized to fit most common North American fuel can openings, and the 51" flexible hose reaches into vehicle filler necks, lawn equipment, ATVs, and portable generators without hoisting heavy containers. That length and variety let you fill hard-to-reach tanks while the pump sits beside the fuel can. A storage bag keeps adapters and hose organized between uses.

• Four adapter sizes for broad can compatibility
• 51" hose reaches tanks, mowers, ATVs, and generators
• Flexible poly hose reduces kinks and fits tight spaces
• Storage bag included for tidy transport

How fast and durable is the pump for repeated use?

The MAYALEAD motor delivers up to 3.8 gallons per minute (about 12 L/min), giving brisk transfer times for larger tanks while operating with low noise. The outer shell is rugged ABS and internals use quality components for dependable cycling. One-button control keeps operation simple, and built-in leak protection features limit accidental drips.

• High flow rate: 3.8 GPM / 12 L/min
• Quiet motor suitable for home and field use
• ABS housing and durable internals for longevity
• Simple one-button on/off plus leak protection

Who is this for: The MAYALEAD Automatic Electric Fuel Transfer Pump suits homeowners, small-farm operators, mechanics, landscape professionals, and outdoor enthusiasts who need a portable, fast, and tidy way to move fuel. It’s ideal for anyone tired of lifting heavy cans or monitoring fills—use it for cars, generators, lawn mowers, ATVs, and emergency roadside refuels whenever cordless or USB-powered convenience matters.
