BestCosy Portable Battery Transfer Pump — 2.4 GPM Electric Siphon, 47" Hose, Fits 3–5 gal Containers

The BestCosy portable battery-powered transfer pump is a compact electric siphon that moves gasoline, diesel, oil and water at up to 2.4 gallons per minute using D or AA batteries.

Lightweight and cordless, this hand-friendly pump makes moving liquids from jerry cans, pails, and small tanks easier without lifting or pouring. It includes a 47" discharge hose and a 16" suction tube sized to fit most 3–5 gallon containers. Built with corrosion-resistant plastic and an impeller-driven motor, the unit is intended for non-corrosive fuels and water where mains power isn’t available.

How fast will the pump move fuel or water?

This model delivers up to 2.4 gallons per minute under typical conditions, enough to empty many small cans quickly. Battery life varies with fluid viscosity and battery type, but you can expect to pump substantial volumes on a fresh set of batteries.

• Maximum flow: 2.4 GPM (gallons per minute).
• Hose length: 47" discharge and 16" suction tube.
• Battery runtime: often over 1,000 gallons per set with fresh batteries under ideal conditions.

What power source does it require and how portable is it?

The pump runs on either two D-cell batteries or six AA cells (batteries not included), so it works anywhere without a power cord. The compact footprint and lightweight plastics make it easy to carry in a vehicle, toolbox, or camping pack.

• Batteries accepted: 2x D-cell or 6x AA.
• No external power adapter required — fully cordless operation.
• Small size fits most storage compartments and travel kits.

Which liquids can I safely transfer with this pump?

Designed for gasoline, diesel, light oils and fresh water, the pump handles common fuels used in vehicles, lawn equipment, and portable generators. It is not rated for corrosive chemicals, strong solvents, or acids — always check compatibility and clean the pump after each use.

• Suitable: gasoline, diesel, kerosene, light motor oil, and water.
• Not suitable: corrosive or highly flammable solvents beyond recommended fuels.
• Use a fresh battery set and flush the hoses after use to maintain performance.

How do I install and maintain the transfer pump?

Installation is tool-free: insert the correct batteries, place the suction tube into the source container and the discharge hose into the receiving tank, then press the power switch. Routine maintenance is minimal — rinse with clean fuel or water, dry, and store in a cool, dry place.

• Assembly: battery compartment, suction tube, and discharge hose connect without tools.
• Cleaning: flush with clean liquid after each use, especially when switching fuel types.
• Storage: keep out of direct sunlight and away from corrosive substances.
