Mini Portable Electric Bike Pump Cordless Tire Inflator, 120 PSI Max, 450mAh Battery With Screen, Fast Charging

Carry-ready, the Mini Portable Electric Bike Pump Cordless Tire Inflator is designed for quick, on-the-go tire inflation. With a max of 110 PSI and a featherweight build (only 130g), it’s the ideal companion for cyclists, commuters, and travelers who want precise pressure control without dragging out a bulky pump. It operates on a compact 450mAh battery at 7.4V and requires a fast USB Type-C connection for when you need a top-up in a hurry. A real-time pressure display helps you dial in the exact PSI you want, while memory of the last setting makes the next inflation even faster.

Key specifications

• Battery capacity: 450mAh 7.4V 33.3Wh
• Interface: Type-C 5V 1.5A
• Charging time: 30 minutes

• Weight: 130g

Smart features and real-time monitoring

Remember the air pressure setting value for the last use, and have the memory value ready on the next startup for seamless inflation. After startup, the pump displays real-time air pressure, so you can watch progress as you approach your target. When you reach the desired pressure and shut down the unit (while still plugged in), pressure stability is maintained within 1 PSI, helping avoid under- or over-inflation. The pump also includes practical safeguards: during charging, you can turn the device on but the motor won’t start until you’re ready. If there is no button operation for more than one minute in a non-inflated state, it will automatically shut down to conserve power.

Who is this for?

• Road cyclists and everyday commuters who want reliable tire inflation without carrying a bulky pump or inflator gauge
• Travelers and RV enthusiasts who need a compact, portable inflator for on-the-go tire maintenance
• Parents managing bikes for kids, students with bikes on campus, and anyone who values quick, accurate PSI control
• Emergency kits and second-car setups where space is premium but preparedness matters

Real-world benefits you’ll notice

Accurate tire pressure matters for safety, efficiency, and tire life. This pump’s real-time display lets you dial in exactly 0–110 PSI on typical road tires, helping you optimize traction and rolling resistance without guesswork. The compact, lightweight design makes it easy to stash in a backpack, saddlebag, or glove compartment, turning your bike into a truly self-sufficient vehicle for daily commutes or weekend rides. With fast charging, you’re rarely left waiting, and the memory feature eliminates the step of resetting your preferred PSI each time you inflate. The 1 PSI stability window after reaching target pressure adds a layer of confidence, especially on long rides where minor fluctuations can add up.

How to use

1. Power on the pump and connect the appropriate valve head to your tire valve.
2. Set your target PSI (the memory will recall the last value on the next startup).
3. Press start to begin inflating. Monitor real-time pressure on the display.
4. Stop inflating when you reach the target pressure. The unit will maintain pressure stability if you shut it down without unplugging.
5. After use, unplug or leave plugged in as needed; note that during charging the motor will not start until you initiate inflation.
6. If there is no button operation for more than one minute in a non-inflated state, the device will auto-shut down to save power.
