PETASOON Portable Fuel Transfer Pump 3.8 GPM USB/Battery Portable with Auto-Stop and Anti-Siphon

PETASOON's portable fuel transfer pump is a battery- or USB-powered electric pump that safely moves gasoline or diesel at up to 3.8 GPM with auto-stop sensing and anti-siphon protection.

Compact and lightweight, this pump was redesigned to make refueling, fuel transfer, and small liquid handling faster and less messy. Choose from three power modes (4 AA, 2 AA, or USB), and rely on improved components — a stainless clamp, tougher PP+EVA hose, and a relocated auto-stop sensor — for a more dependable, easier experience when emptying jerry cans, filling lawn mowers, or topping off boats and generators.

How does the PETASOON pump prevent spills and overfilling?

The unit uses an upgraded auto-stop sensor that detects liquid level in real time and halts the pump before the receiving container overflows. A patented anti-siphon mechanism also allows air into the line so flow can be stopped even if the source sits higher than the destination.

• Relocated sensor for improved detection accuracy and stability
• Auto-stop shuts off pump before full capacity to reduce spills
• Anti-siphon design stops uncontrolled flow from higher tanks
• Redesigned hose clip and O-ring seal ensure leak-free connections

What power options are available and how long will it run?

Power the pump with 4 AA batteries for maximum portability, 2 AA batteries for lighter use, or plug into a USB power bank or charger for continuous operation. The 10W motor delivers up to 3.8 gallons per minute when powered by USB, emptying small tanks quickly.

• 3 power modes: 4 AA, 2 AA, or USB connection
• 10W high-power motor reaches up to 3.8 GPM on USB power
• USB option lets you use common power banks or vehicle chargers
• Battery operation provides cordless convenience at remote sites

Is the pump durable and suitable for outdoor use?

The PETASOON pump has multiple hardware upgrades aimed at durability: a stainless-steel nozzle clamp with metal spring, a tougher PP+EVA composite hose that resists corrosion and cold, and a multi-piece hose clip with an O-ring for a reliable seal. These improvements reduce cracking, perforation, and leakage in outdoor conditions.

• PP+EVA hose: 30% tougher and 20% more corrosion resistant than prior material
• Works down to -50°F without cracking
• Stainless-steel nozzle clamp ensures stable attachment to tank openings
• Three-part hose clip prevents loosening and eliminates drips

How fast and practical is it for everyday tasks?

With its 3.8 GPM peak flow, the pump empties a 5-gallon container in about 79 seconds and a 15-gallon tank in under four minutes on USB power. The lightweight 1 lb body, simple on/off controls, and spill-reducing nozzle make it easy to use for lawn equipment, generators, small boats, and emergency refueling.

• High flow rate saves time when transferring fuel
• Weighs just 1 lb for easy handling and transport
• Simple push-button operation ideal for seniors and non-technical users
• Saves money and effort—no funnels, scoops, or heavy lifting required

Who is this for? The PETASOON fuel transfer pump suits homeowners, RV and boat owners, landscapers, mechanics, and anyone who needs a safe, portable way to move gasoline or diesel without heavy lifting. It’s especially useful for older adults or those with limited mobility who want a low-effort solution, and makes a practical gift for people who handle fuel for tools, toys, or emergency equipment.
