DEMAKIMI Cordless Fuel Transfer Pump 5.0 GPM — 3-in-1 Power (Battery/12V) with Auto-Shutoff and Reinforced Hose

DEMAKIMI 5.0 GPM Cordless Fuel Transfer Pump is a portable, high‑flow pump with three power options and an automatic shutoff that transfers fuel quickly and safely.

This battery‑powered transfer pump is built for fast, hands‑free refueling and fluid movement wherever you need it — garage, boat dock, farm, or roadside. It delivers up to 5 gallons per minute (18.9 L/min) and includes adaptors, cables, and a beep‑alert auto‑stop sensor so you can move fuel into tanks or containers with minimal fuss and no extra accessories required.

How fast will this pump refill my tank or jerry can?

The pump moves liquid at up to 5 GPM (18.9 L/min), so a typical 15‑gallon tank is filled in roughly 3–4 minutes. Flow is steady thanks to the reinforced hose and efficient motor architecture, cutting wait times for routine transfers.

• 5.0 GPM maximum flow rate for rapid transfers
• 18.9 L/min metric equivalent provided
• Reinforced hose reduces kinks that slow flow
• Suction tube fits narrow openings for tight jerry cans

What power sources can I use and what comes in the box?

DEMAKIMI includes three complete power options so you can use it from a cordless tool battery, a vehicle, or a standard 12V socket without buying extra adapters. All necessary cables are supplied, making the pump ready to work right away.

• Compatible with Craftsman 20V tool batteries (battery sold separately if not included)
• Automotive battery alligator clip cable for direct 12V battery hookup
• 12V cigarette lighter adapter for vans, trucks, and power inverters
• Plug‑and‑play setup — all cables provided for on‑the‑spot operation

Will it prevent spills and overfilling?

The pump features a built‑in sensor that stops flow automatically when the receiving tank reaches capacity and sounds a beep to let you know it’s done. This smart auto‑stop system minimizes overflow risk and eliminates the need to supervise every transfer.

• Automatic shutoff triggered by onboard sensor
• Audible beep confirms transfer completion
• Suitable for gasoline, diesel, light oils, and water
• Reduces chance of spills and messy cleanups

What fittings and maintenance are included to keep it working?

The pump ships with five adaptors to fit most common North American container openings, plus a long suction tube and a reinforced delivery hose for reliable seals and fewer leaks. Simple rinsing after use preserves seals and motor life.

• Five adaptors: 2.0", 2.1", 2.5", 2.75", and 3.75" to match many can sizes
• 1.3" suction tube for narrow‑neck containers
• Reinforced hose resists kinking and maintains steady flow
• Recommended: rinse with clean water after use to protect motor and seals
