knoweasy Battery Powered Transfer Pump — 2.2 GPM Cordless Fuel & Water Pump, Battery-Operated Portable

The knoweasy Battery Powered Transfer Pump is a portable, cordless liquid mover that safely transfers fuel and water at about 2.2–2.6 gallons per minute using standard D or AA batteries.

Compact and lightweight, this battery-driven transfer pump was designed for people who need a dependable way to move water, gasoline, diesel, kerosene or light oils without cords, generators or messy siphoning. It pairs a 1/2" discharge hose and a 16" suction tube with an impeller-driven motor to deliver steady flow from cans, jerrycans or buckets. The construction uses corrosion-resistant materials so the unit holds up to repeated outdoor use.

How fast and how far can this pump move liquids?

The knoweasy pump delivers roughly 2.2–2.6 gallons per minute under normal conditions and the manufacturer reports it can move over 1,000 gallons on a single set of batteries. Flow and runtime vary with battery type, liquid viscosity and elevation, but the impeller design provides consistent suction for quick transfers.

• Nominal flow: about 2.2–2.6 GPM
• Discharge hose: 1/2 inch diameter, 24 inches long
• Suction tube: 16 inches, fits 3–5 gallon cans and common jerrycans
• Runtime: can exceed 1,000 gallons per battery set depending on conditions

What power source does it use, and how portable is it?

This model is fully cordless and runs on batteries so you can use it wherever you need liquid moved—no outlet required. It accepts either two D batteries or six AA batteries (batteries not included), letting you choose a balance of runtime and weight for trips or emergency use.

• Battery options: 2 x D cells or 6 x AA cells (not included)
• Lightweight for carrying to vehicles, boats, campsites or garden areas
• No electrical cord or adapter required—ideal for remote locations

Which liquids can I use with this pump, and what should I avoid?

The pump is intended for non-corrosive liquids such as water, gasoline, diesel, kerosene and light oils. It is not suitable for strong acids, bases, or other corrosive chemicals; prolonged exposure to those substances can damage seals and internal parts.

• Safe for: water, gasoline, diesel, kerosene, light motor oils
• Not for: corrosive chemicals, concentrated acids or bases, highly viscous fluids
• Designed materials resist routine corrosion from fuels and water

How easy is it to set up, clean and maintain?

Setup is straightforward—insert batteries, attach the 16" suction tube and 24" discharge hose, then place the suction tube in your source container. Cleaning requires flushing with a compatible liquid (water for water, appropriate fuel-safe cleaner for gasoline/diesel) and drying before storage.

• Tool-free assembly: hose and suction tube attach quickly
• Routine care: flush lines after each use and allow to dry
• Replace batteries when flow weakens; inspect seals periodically

Who is this for: The knoweasy Battery Powered Transfer Pump is a practical choice for homeowners, DIYers, boaters, car enthusiasts and outdoor adventurers who need a portable, no-fuss solution to move fuel or water. It suits anyone who values lightweight, cordless convenience for topping off tanks, draining small containers, refueling equipment or handling routine fluid transfers where outlets are unavailable.
