DEMAKIMI Cordless Fuel Transfer Pump 5.0 GPM — 3-in-1 Power (Craftsman 20V, 12V, Clips) with Auto‑Stop

The DEMAKIMI 5.0 GPM Cordless Fuel Transfer Pump is a portable, battery-ready fuel and liquid transfer solution with three power options, a 5-gallon-per-minute flow, and an automatic shut-off sensor.

Designed for homeowners, boaters, farmers, and roadside users, this compact pump combines fast flow with adaptable power inputs so you can move gasoline, diesel, light oils, or water without hauling heavy containers. It includes multiple adapter fittings for common container openings, a reinforced hose, and an audible auto-stop that prevents overfilling. Everything needed to get started is included in the box.

How quickly will this pump transfer fuel?

The pump delivers up to 5 gallons per minute (about 18.9 L/min), which means filling a typical 15-gallon container takes roughly 3–4 minutes. High flow reduces wait time and improves efficiency when refueling equipment, vehicles, or storage drums.

• 5.0 GPM (18.9 L/min) maximum flow rate
• 15‑gallon tank filled in about 3–4 minutes
• Reinforced hose designed to resist kinks and leakage

What power options are available and what’s included?

This model supports three independent power sources so you can use it virtually anywhere. It works with Craftsman 20V tool batteries and includes both automotive alligator clips and a 12V cigarette lighter adapter—no extra cords required.

• Compatible with Craftsman 20V batteries (battery not always included—check pack contents)
• Automotive battery alligator clips for direct 12V hookup
• 12V cigarette-lighter adapter for vehicle accessory ports

Will I avoid spills and overfills using this pump?

The pump features a built-in sensor that stops flow automatically when the receiving container reaches capacity and emits a beep to alert you. That auto-stop reduces the need for constant supervision and helps prevent spills during transfers.

• Smart auto-stop sensor cuts power when tank is full
• Audible beep notifies you when transfer ends
• Safe for gasoline, diesel, light oils, and water when used per instructions

Which container sizes and openings does it fit?

DEMAKIMI includes five threaded adaptors covering common North American container openings, plus a narrow suction tube for tight necks. The set supports small jugs up to larger drums, offering a secure seal to minimize leaks during transfers.

• Five adaptors: 2.0", 2.1", 2.5", 2.75", and 3.75" openings
• 1.3" suction tube for narrow-neck containers
• Adapters designed to create a tight seal on standard fuel cans and drums

Who this is for: If you need a portable, fast, and versatile way to move fuel or liquids—whether refilling ATVs, boats, tractors, or emergency jerry cans—this pump fits neatly into a toolbox, trunk, or service van. It’s aimed at DIYers, landscapers, mariners, and anyone who wants quicker transfers with less mess and straightforward power options. For long-term reliability, rinse the pump with clean water after transferring non‑flammable liquids, and note that DEMAKIMI backs each unit with rigorous pre-shipment testing and U.S.-based customer support.
