keimi Electric Fuel Transfer Pump 3.8 GPM with Hand-Trigger Nozzle — AA/USB Portable Control

If you need a safe, portable way to move gasoline, diesel, or kerosene without heavy lifting or messy funnels, this Keimi pump gives you controlled flow with an easy squeeze-and-release nozzle. It runs on four AA batteries for cordless use or from a USB power source, and its 51-inch rubber hose and four adapters help it fit most common fuel containers.

How does the hand-trigger nozzle change refueling control?

The squeeze-to-run, release-to-stop nozzle puts flow control directly in your hand, avoiding automatic shutoffs and letting you stop transfer at the exact moment you want. This is useful for short pours, topping off tanks, or transferring between containers where precision matters.

• Immediate on/off with a finger trigger for precise pours
• No auto-sensor—operator decides when flow stops
• Suitable for attended operation where visibility and control are required

What power options does the pump support and how long will it run?

Keimi’s pump accepts four AA batteries for fully portable use and also runs via USB when plugged into a power bank, vehicle adapter, or wall charger. Battery life depends on cell quality and usage patterns, but USB power provides continuous operation for extended jobs.

• Works with four AA batteries (not included) for off-grid refueling
• USB input works with power banks, car chargers, or wall adapters
• High-flow 3.8 gallons-per-minute rate for faster transfers when powered

Which equipment and fuels are compatible with this transfer pump?

The pump is designed for common liquid fuels like gasoline, diesel, and kerosene and fits many outdoor machines and small engines. Use it to refill lawn mowers, portable generators, tractors, ATVs, motorcycles, boats, and other compatible tanks that accept fuel safely.

• Safe for gasoline, diesel, and kerosene transfers (follow fuel safety guidelines)
• Includes four adapters to match popular gas-can openings—confirm fit before use
• 51-inch commercial-grade rubber hose provides reach for tight or distant tanks

What safety and operational steps should I follow while using it?

Operate the pump in a well-ventilated area away from open flames, heat sources, and sparks. Keep the receiving tank in sight, maintain a firm grip on the nozzle, and turn the pump off before disconnecting the hose or adapter to avoid spills.

• Always attend the pump while fuel is flowing; never leave it unattended
• Switch power off before removing the nozzle or changing adapters
• Store and use away from ignition sources and in ventilated spaces

This Keimi electric fuel transfer pump blends portability, control, and compatibility for homeowners, landscapers, and recreational vehicle owners who need reliable attended refueling. Its battery and USB power options plus the flexible hose and adapter set make it a practical accessory for weekend mechanics, boaters topping off tanks, or anyone who prefers a spill-reducing solution over manual pouring. If you want a compact pump to speed up fuel transfers while keeping control in your hands, Keimi’s 3.8 GPM model is built for that purpose.
