ETENWOLF S0 Mini Electric Bike Pump with Gauge, 150 PSI Auto Stop
Product description
For cyclists who want a compact pump for roadside tire adjustments, the ETENWOLF S0 Mini combines electric inflation with a built-in pressure gauge. Its palm-sized design makes it practical to carry on rides.
The pump supports up to 150 PSI and works with Presta and Schrader valves, giving riders a single tool for different bicycle setups. A Presta nozzle adapter is used for road-bike valves.
An automatic stop function and real-time pressure display help you set an inflation target without relying only on feel. It can also inflate motorcycles and sports balls.
Size & fit
The compact S0 Mini is designed to travel with your riding gear rather than take up the space of a larger floor pump. Pack it for a long ride, keep it with your repair essentials, or bring it along for quick tire adjustments away from home. Buyers also highlight its portable size and say it fits in bike and rear saddle bags, which makes it convenient to carry on rides.
Its hose rotates 360 degrees to make valve access easier when a wheel or frame leaves little room to maneuver. For road-bike use, attach the Presta nozzle adapter to the tire before inflating. The pump also supports Schrader valves, so it can serve bikes with either valve type.
Where it shines
The S0 Mini is built for riders who want powered inflation and a pressure reading in one handheld device. The digital gauge displays tire pressure in real time, while the automatic stop function halts inflation when the selected pressure is reached. That combination helps with repeatable pressure adjustments before heading out or during a ride.
Its stated maximum pressure is 150 PSI, and its airflow capacity is 18 liters per minute. ETENWOLF gives an example of inflating a 700×23C tire at 80–100 PSI in 20 seconds, and describes filling a road-bike tire from 0 to 100 PSI in under a minute. Actual inflation time depends on the tire and starting pressure. Beyond bicycles, the included ball needle and balloon valve support use with sports balls and balloons, the pump is also suitable for motorcycle tires.

What to clarify
Can it inflate both Presta and Schrader tires? Yes. The pump supports both valve types. For a road-bike tire with a Presta valve, attach the Presta nozzle adapter to the tire before inflating.
How do you control the tire pressure? Use the digital gauge to view pressure as you inflate and set the target. The pump automatically stops when it reaches that selected pressure.
Can it be used for anything besides bicycle tires? It is also suitable for motorcycle tires and sports balls. A ball needle is listed among the included accessories for inflating balls.
When it makes sense
Choose the S0 Mini if you want a portable electric pump that brings pressure monitoring and automatic shutoff to bicycle maintenance on the go. Its Presta and Schrader support, compact carry-friendly design, and stated uses beyond bikes make it a useful fit for cyclists who want one small inflator for rides and other inflation needs.
