keimi Portable Fuel Transfer Pump — 3.8 GPM Auto-Stop, 51" Hose, USB & Battery Powered

Keimi Portable Fuel Transfer Pump is a compact, battery or USB-powered pump with an auto-stop nozzle that safely transfers gasoline, diesel, or oil at up to 3.8 gallons per minute. This lightweight, travel-ready pump combines fast flow, an extra-long 51" hose, and four universal adapters to fit most North American fuel cans. It’s designed for homeowners, mechanics, and outdoor enthusiasts who need a tidy, spill-resistant way to move fuel between containers, vehicles, and equipment without a permanent installation or heavy tools.

How does the auto-stop feature prevent spills?

The built-in auto-stop sensor detects when the receiving tank is full and immediately halts fuel flow, reducing the risk of overflows and messy cleanup. This automated shutoff helps maintain safety around engines and fuel-handling areas.

• Auto-stop sensor at nozzle tip for automatic shutoff
• Prevents overflows and reduces fumes around work areas
• Simple one-piece nozzle—no separate float or manual monitoring

What power options are available for on-the-go use?

The unit runs on four AA batteries for true cordless portability and can also operate via USB when connected to a power bank, car charger, or wall adapter. That dual-power design ensures uninterrupted pumping whether you’re in the garage or offsite.

• Uses 4 AA batteries for immediate mobile use
• Included USB cable supports power banks and vehicle adapters

Will it fit my fuel cans and reach tight openings?

Keimi includes four adapters (2.0", 2.1", 2.75", 3.75") to match most standard North American can necks and fuel fillers. The 51" hose provides added reach so you can feed tanks that sit deep or distant from the source container without tilting or creating mess.

• Four adapter sizes for broad compatibility
• 51" flexible hose for extended reach and convenience
• Compact nozzle fits into narrow filler necks and small tanks

How fast and efficient is the pump for daily tasks?

At up to 3.8 gallons per minute, this pump moves fuel quickly, cutting the time spent topping off mowers, generators, or utility vehicles. The design balances strong flow with controlled delivery so you avoid surges that can cause splashes.
