DEMAKIMI 5.0 GPM Cordless Fuel Transfer Pump — 3‑in‑1 Power (Battery, Car, 12V) with Auto‑Stop

The DEMAKIMI 5.0 GPM Cordless Fuel Transfer Pump is a portable, battery-, vehicle-, and 12V‑powered pump that moves fuel at up to 5 gallons per minute and stops automatically when the receiving tank is full.

This compact transfer pump is built for fast refueling around the yard, on the water, or at the worksite. It ships with a full set of power cables and five adaptor sizes so you can use it with common Craftsman 20V batteries, a car battery, or a 12V cigarette lighter outlet. The reinforced hose and multiple adapters make it compatible with spare jugs, SUVs, boats, tractors, and drums while the smart auto‑stop sensor helps prevent spills.

How quickly will it fill my fuel can or tank?

At 5 gallons (18.9 L) per minute, this pump fills typical portable tanks and jerry cans much faster than hand‑pumping methods. A 15‑gallon tank takes roughly 3–4 minutes depending on hose length and outlet height.

• 5.0 GPM rated flow for fast transfers
• Reinforced hose reduces kinks and flow loss
• Compact motor keeps weight manageable for handheld use

What power sources does the pump support and why does that matter?

DEMAKIMI designed this pump with three power options to keep you working whether you’re away from shore power or at the garage. All cables are included so you won’t need extra purchases to start moving fuel.

• Works with Craftsman 20V tool batteries for cordless convenience
• Includes automotive battery alligator clips for jump‑style hookup
• 12V cigarette lighter adapter for use with vehicle accessory outlets

Will it avoid overfilling and leaks when transferring fuel?

The pump uses a built‑in sensor that automatically stops flow when the receiving container reaches capacity and issues a beep alarm so you don’t have to watch the transfer. Matched with the included adaptors and a snug hose seal, it minimizes drips and mess.

• Smart auto‑stop sensor prevents overfills and spills
• Audible beep alerts when the transfer completes
• Five adaptor sizes provide tight seals for many container openings

What accessories and maintenance should I expect?

The package contains five different adaptor sizes and a 1.3" suction tube suitable for narrower openings. DEMAKIMI also runs a three‑stage quality check and offers U.S.‑based support for troubleshooting or warranty help.

• Included adaptors: 2.0", 2.1", 2.5", 2.75", 3.75" to fit standard containers
• Reinforced hose and suction tube to fit narrow openings and resist leaks
• Recommended rinse with clean water after use to prolong seals and motor life

Who is this for: The DEMAKIMI 5.0 GPM Cordless Fuel Transfer Pump suits homeowners, boaters, farmers, and tradespeople who need a fast, portable, and versatile way to move gasoline, diesel, light oils, or water between containers. It’s ideal if you value quick transfers, multiple power options, and built‑in safety features without needing additional adapters or batteries.
