PETASOON Portable Fuel Transfer Pump USB Battery 3.8 GPM — Auto‑Stop, Anti‑Siphon

PETASOON's portable fuel transfer pump is a lightweight USB- and battery-powered electric pump that moves gasoline or diesel quickly (up to 3.8 GPM) while preventing spills with an auto-stop sensor and anti-siphon design.

This compact fuel transfer solution is built for homeowners, boaters, RV owners and anyone who needs to move fuel safely without heavy lifting or messy funnels. It supports three power modes (USB, 4 AA, or 2 AA), features an upgraded motor for faster flow, and adds design improvements — tougher hose material, stainless-steel nozzle clamp, and a reliable auto-stop sensor — to reduce leaks and make refueling tasks faster and simpler.

How fast will PETASOON empty a fuel container?

The upgraded 10W motor delivers up to 3.8 gallons per minute under USB power, so a typical 5-gallon portable tank can be emptied in roughly 79 seconds and a 15-gallon tank in under four minutes. Actual speed varies with battery condition, hose routing and height differences between tanks.

• Max flow: 3.8 GPM with USB power
• 5-gallon tank: about 79 seconds (USB)
• 15-gallon tank: under 4 minutes (USB)
• Battery mode: slightly lower flow depending on cell type and charge

Will the pump stop automatically and avoid overfilling?

Yes — an upgraded auto-stop sensor continuously detects liquid level and halts the pump before the receiving container overfills. The sensor has been repositioned for improved accuracy and stability so you can transfer fuel with less monitoring.

• Auto-stop detects liquid level in real time
• Prevents overflow and reduces spill risk
• Repositioned sensor for better reliability
• Easy on/off controls for manual override

Can I use this pump in different places and power it easily?

Absolutely — PETASOON offers three power supply modes for versatility: USB connection to a charger or power bank, 4 AA batteries for maximum runtime, or 2 AA batteries for lighter use. This makes the pump suitable for garages, boats, campsites and emergency kits where outlets may not be available.

• USB-powered: works with power banks and chargers
• 4 AA or 2 AA battery options for off-grid use
• Lightweight (about 1 lb) and portable for travel
• Simple on/off buttons — no tools or funnels needed

How does PETASOON prevent leaks, siphoning and hose damage?

Several upgrades reduce leakage and long-term wear: a redesigned three-part hose clip with O-ring seal locks the hose to the pump, a stainless-steel nozzle clamp secures to tank openings, and a PP+EVA hose material increases toughness and corrosion resistance. A patented anti-siphon mechanism also allows air into the line to stop unwanted flow when tanks are at different heights.

• Three-component hose clip with O-ring ensures zero leakage
• Stainless-steel nozzle clamp with metal spring for firm fit
• PP+EVA hose resists cracking and perforation at low temperatures
• Patented anti-siphon lets you stop transfer anytime

Who is this pump for? PETASOON's portable fuel transfer pump suits homeowners, RVers, boat owners, mechanics and anyone who regularly handles small to medium fuel transfers and wants a safer, faster alternative to pouring from jerry cans. It’s especially useful when outlets are limited — the USB and battery power options make it handy on the road, on the water, or at remote job sites. Lightweight and senior-friendly controls also make it a practical gift for older family members who need to refuel lawn mowers, generators, or small engines without bending or lifting heavy containers.
