The best battery powered transfer pump moves fuel from a can to a tank without lifting, siphoning by mouth or spilling across a garage floor. A generator that needs fuel at dusk, a boat tank that sits low in the hull and a lawn mower that ran dry all call for the same thing: a pump that starts with a button and stops when the tank is full. The pumps below run on batteries or USB-C, and every figure quoted comes from the listings. The ranking follows the Solar Score weights, with performance, build, value, stated safety features and warranty terms each counted.

Where the points went
The Solar Score weighs performance, build, value, safety and warranty. For a transfer pump, safety means the auto-stop sensor, leak protection and beep warning the listing actually states; a pump that states none scores zero on that line, whatever its flow rate. 4 of the 5 pumps state a warranty term: the VEECAP with a 2-year term, and the SLOTHZTECH, DEWAY and ANSE with a 1-year term. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| VEECAP 3.8 GPM Pump | 9.7 | 32 | 21 | 21 | 9 | 3 |
| SLOTHZTECH 3.8 GPM Pump | 9.7 | 32 | 21 | 21 | 9 | 3 |

| HORUSDY 2.2 GPM Pump | 9.5 | 27 | 19 | 20 | 6 | 0 |
We place weighted points on a scale whose ends are 9.2 and 9.8. Because the mapping is straight, a unit with more points never shows less.
How to choose the best battery powered transfer pump
Flow rate and power
Flow runs 3.8 gallons per minute on the VEECAP and SLOTHZTECH pumps, 2.7 gallons per minute on the ANSE, 2.6 gallons per minute on the DEWAY and 2.2 gallons per minute on the HORUSDY. The VEECAP and SLOTHZTECH pumps run on 4 AA batteries or USB-C, the HORUSDY runs on 2 D batteries or 6 AA batteries, the DEWAY runs on 2 D batteries, and the ANSE has a built-in 6000mAh battery charged by USB-C. A higher flow rate fills a tank faster, while a rechargeable battery removes the need for spare batteries. A portable power station can charge the USB-C pumps in the field; see the portable power station picks.
Hoses and adapters
The VEECAP and SLOTHZTECH pumps have a 51-inch outtake hose and a 23-inch intake hose, with 4 adapters for most North American fuel cans. The ANSE has a 3.3-foot hose, the HORUSDY has a hose up to 2 feet with a 16-inch suction tube, and the DEWAY has an extra-long suction tube and transfer hose. Check the adapter size against the can opening before ordering: the VEECAP does not fit openings smaller than 1.3 inches, and the ANSE may not fit openings under 1.3 inches.
| Pump | Flow | Power | Hose |
|---|---|---|---|
| VEECAP 3.8 GPM Pump | 3.8 GPM | 4 AA or USB-C | 51 in |
| SLOTHZTECH 3.8 GPM Pump | 3.8 GPM | 4 AA or USB-C | 51 in |
| ANSE X1 Ultra Pump | 2.7 GPM | 6000mAh rechargeable | 3.3 ft |
| DEWAY WAYPUMP07 Pump | 2.6 GPM | 2 D batteries | Not stated |
| HORUSDY 2.2 GPM Pump | 2.2 GPM | 2 D or 6 AA | 2 ft |
Auto-stop and leak protection
The VEECAP and SLOTHZTECH pumps stop the flow when the tank is full, with a sensor that also stops the flow when it touches the fuel. The SLOTHZTECH adds a beep warning when it stops, and the VEECAP adds a leak guard with a reinforced leak-proof pipeline. The ANSE states a leak-proof design, while the DEWAY and HORUSDY state no auto-stop or leak protection. Check the auto-stop before ordering, since a pump that keeps running after the tank fills spills fuel. For moving water in an RV, see the RV water pump picks.
Liquids and compatibility
The pumps here move gasoline, diesel, kerosene and light oil, and the ANSE also moves non-potable water. The HORUSDY and DEWAY listings exclude corrosive liquids, and the ANSE is not for oil or beverage. The DEWAY listing says to confirm liquid compatibility before use and dedicate the pump to 1 liquid type. The VEECAP does not fit Scepter SmartControl cans or barrels taller than 23 inches.
Sizing Notes
- Match flow to the tank: 3.8 gallons per minute on the VEECAP and SLOTHZTECH, 2.7 on the ANSE, 2.6 on the DEWAY and 2.2 on the HORUSDY.
- Match power to the site: 4 AA batteries or USB-C on the VEECAP and SLOTHZTECH, 2 D batteries on the DEWAY, 2 D or 6 AA on the HORUSDY and a built-in 6000mAh battery on the ANSE.
- Match the hose to the can: 51 inches on the VEECAP and SLOTHZTECH, 3.3 feet on the ANSE and 2 feet on the HORUSDY.
- Check the opening: 1.3 inches is the smallest opening the VEECAP and ANSE fit.
- Check the warranty: 2 years on the VEECAP, 1 year on the SLOTHZTECH, DEWAY and ANSE, and no term stated on the HORUSDY.
