A preset-pressure screen and automatic shutoff can reduce the need to monitor inflation continuously.

What to know before buying

Listing details to confirm

Listing details are inconsistent about charging time, with one section claiming 25 minutes and another saying about 30 minutes. The stated 200-second runtime and customer reports of mixed battery life mean the number of tires per charge is not assured. The listing also says the pump gets hot during use and advises using the silicone protector. Press the valve firmly to avoid air leakage.

Who is it for?

A good fit for

Cyclists seeking a small rechargeable pump for occasional roadside inflation.
Riders using Presta or Schrader valves who want a displayed pressure target and automatic shutoff.

Less suited to

Riders needing long continuous pumping or a clearly established number of inflations per charge.
Buyers who prefer a manual pump or need a pump explicitly specified for vehicle tires.

Frequently asked questions

What is the pump's maximum pressure?

The listing specifies a maximum of 120 psi. This is a stated product specification, not an independently verified measurement.

Which valves does it support?

The listing says it supports both Presta and Schrader valves. It advises pressing the pump firmly onto the valve to avoid air leakage.

How long does a charge take?

The listing conflicts: one feature claim says 25 minutes, while another says about 30 minutes with the supplied Type-C cable. Check the current listing details.

How long can it run on a charge?

One claim states 200 seconds after a full charge, but the number of tires inflated varies with tire size and pressure. Customer feedback also reports mixed battery-life experiences.
