keimi Electric Fuel Transfer Pump 3.8 GPM with Hand-Trigger Nozzle — USB/AA Power, 51" Hose

Keimi Electric Fuel Transfer Pump is a portable, hand-triggered 3.8 GPM pump that moves gasoline, diesel, or kerosene quickly and safely with either AA batteries or USB power.

This compact fuel transfer tool blends convenience and control for DIYers, landscapers, and boat owners who need a fast way to move fuel between containers and equipment without bulkier rigs. The unit emphasizes attended operation: you squeeze the nozzle to start flow and release to stop, giving you immediate control during refueling. It ships with a 51-inch commercial-grade rubber hose and four common gas-can adapters so you can reach awkward openings and work across multiple machines.

How does the hand trigger nozzle change the refueling workflow?

The squeeze-to-run, release-to-stop nozzle removes automatic shutoffs and places flow control directly in your hand. This reduces unexpected stops when pouring into nonstandard openings and avoids overfilling when you keep the receiving tank in view. It’s ideal for tasks that require short bursts or careful topping off.

• Immediate on/off with manual trigger for precise control
• No auto-stop sensor—prevents premature cutoff in odd-shaped inlets
• Attended operation recommended for visibility and safety

What power options are available and how long will it run?

The pump runs on four AA batteries or via a USB power source, giving you flexible power choices for field or garage use. Use a suitable power bank, vehicle USB port, or wall adapter when available for extended operation; batteries are best for portable quick jobs. Battery life varies by battery quality and duty cycle, so keep spares on hand for longer projects.

• Powered by four AA batteries (not included) for portable use
• USB input compatible with power banks, car chargers, and adapters
• 3.8 gallons-per-minute transfer rate for faster fills than manual siphoning

Which fuels and machines can this pump service safely?

The Keimi pump is designed for common liquid fuels: gasoline, diesel, and kerosene. It’s suitable for transferring fuel into lawn mowers, generators, tractors, motorcycles, ATVs, and many small boats—whenever you need a controlled fill into a separate tank or container. Always use in a ventilated space and follow fuel-handling best practices.

• Compatible with gasoline, diesel, and kerosene
• Works with yard equipment, generators, powersports, and small marine engines
• Includes four adapter sizes—check can openings before use

How durable and portable is the pump for frequent outdoor use?

The unit pairs a sturdy 51-inch rubber hose with a compact motor housing to withstand regular transfers and provide reach. The commercial-grade hose resists kinks and is sized for repeated handling, while included adapters let you fit a range of fuel can spouts. It’s built for portability so you can carry it to the equipment rather than moving heavy tanks.

• 51-inch flexible rubber hose for extra reach and reduced kinking
• Four adapters (2.0, 2.1, 2.75, 3.75 inches) for can compatibility
• Lightweight housing and hand-trigger nozzle for easy transport

Who is this for: The Keimi electric fuel transfer pump suits homeowners, landscapers, fleet managers, and outdoor enthusiasts who need a fast, portable way to move fuel without bulky gear. It’s best for users who will supervise filling, prefer manual flow control, and want the flexibility of battery or USB power when working with common gasoline, diesel, or kerosene equipment.
