@utos 3.5GPM Portable Li‑Battery Fuel Transfer Pump — 15000mAh, Auto Shutoff, Type‑C Recharge

The @utos 3.5GPM Li-Battery Portable Fuel Transfer Pump is a rechargeable, UL/CE‑listed pump that moves gas, diesel, kerosene or non‑potable water at up to 3.5 gallons per minute with automatic shutoff sensing.

Compact and portable, this battery-powered transfer pump is built around a high-capacity 15000mAh LiFePO4 battery and a beefed-up motor to make refueling vehicles, topping off containers, draining tanks or moving liquids at a campsite quicker and less messy than manual siphoning. Safety certifications, reinforced hosework and a Type‑C recharge port make it practical for home garages, outdoor use and light commercial tasks where a reliable, spill‑reducing transfer solution is needed.

How quickly and how much liquid can it move?

The pump delivers up to 3.5 gallons per minute (about 220 ml/s) thanks to an enlarged motor and optimized transmission. A full charge provides extended runtime suitable for many single‑session jobs.

• Peak flow rate: 3.5 GPM (220 ml/s)
• Battery: 15000mAh LiFePO4 for long cycle life
• Estimated runtime: up to ~4 hours on a full charge
• Capacity example: can transfer roughly 580 five‑liter tanks per full charge

Will it prevent overfilling and spills?

Yes — an integrated automatic sensing device detects liquid level at the outlet and shuts the pump off within 1–2 seconds, reducing overflow risk and eliminating the need to monitor the flow constantly. This feature makes one‑person transfers much safer and cleaner.

• Automatic shutoff activates when sensing point is reached
• Response time: approximately 1–2 seconds
• Reduces manual intervention and overflow risk

What materials and hose specifications ensure durability?

The pump comes with reinforced, thicker PVC hoses and multiple sealing rings to minimize leaks and improve longevity. Hose length and diameter have been upgraded from common market sizes to suit larger containers and improve flow stability.

• Hose length: 120 cm (47.25 in) for easier reach into drums
• Hose diameter: 2 cm (0.79 in) for improved throughput
• Reinforced PVC construction with extra sealing rings for leak prevention

Which liquids and containers are compatible with this pump?

The @utos transfer pump is designed for a variety of non‑pressurized liquids commonly used around vehicles and outdoors. It is not intended for potable drinking water or caustic/abrasive chemicals unless explicitly specified by the manufacturer.

• Compatible: gasoline, diesel, kerosene, light oils, non‑potable water
• Not for: acidic, highly viscous, or food/drink applications without confirmation
• Outlet requirement: oil drum or container opening should exceed ~1.3 in diameter

Who is this product for? The @utos 3.5GPM Li‑Battery Portable Fuel Transfer Pump suits vehicle owners, motorcyclists, DIY mechanics, boaters and campers who need a fast, cordless way to move fuel or water without relying on manual siphons or bulky wired pumps. It also fits light workshop or farm tasks where safe, portable transfer with automatic shutoff reduces mess and the chance of spills. If you need higher flow, frequent heavy‑duty industrial pumping, or certified potable water handling, consider a specialized unit matched to those needs.
