ETENWOLF S0 Mini Electric Bike Pump — 150 PSI Portable Inflator
Product description
Compatibility and use
This S0 pump supports both Presta and Schrader valve types so it works across road, hybrid and mountain bikes. A Presta nozzle adapter is supplied and should be attached to Presta stems when inflating road tires. The unit can also handle motorcycle tires and inflatable sports equipment using the included fittings.
Performance
The compact electric motor pushes air at up to 18 L/min and reaches a maximum of 150 PSI. That flow rate lets it refill a 700×23C tire from 80–100 PSI in roughly 20 seconds and take an entirely flat road tire up to 100 PSI in under a minute. The device automatically stops when the preset pressure is reached to prevent overinflation.
Battery and gauge
A built-in 2400 mAh rechargeable battery powers the pump. On a full charge it can inflate about eight fully flat bicycle tires or around eighteen low-pressure fills, depending on tire size and target pressure. A bright LED digital pressure readout shows real-time pressure with a stated accuracy of ±1 PSI and the unit recalls the last pressure setting via its memory function.
Design and handling
The S0 is palm-sized and weighs approximately 0.54 lbs, making it easy to stow in a seat pack or backpack. A 360°-rotating hose helps line up the chuck without awkward angles. Controls are simple to set the desired PSI and start inflation; the pump will ramp down as it approaches the target.
What’s in the box
The package contains: 1 S0 Mini Electric Bike Pump, 1 Presta valve adapter, 1 air chuck, 1 ball needle, 1 balloon valve, 1 drawstring storage bag and 1 user manual. For support, contact the manufacturer if any concerns arise.
Pros

- Compact and lightweight for easy transport
- Accurate LED gauge and auto-stop feature
Cons

VerdictA compact, battery-powered inflator that delivers fast, accurate pressure for road and mountain bikes as well as motorcycles and sports gear. It combines a bright digital gauge, auto-stop on target pressure and a 2400 mAh rechargeable battery in a lightweight package. Ideal for riders who want a portable, quick solution for topping up or repairing tires on the go.

Denis T. 5/5
Easy to use, surprisingly powerful
Very user-friendly: set the PSI, start the pump, and it stops when done. Small footprint and memory feature are handy. Recommended to friends.

Solid performer for casual riders
Worked well on several test tires. Reasonably quiet and fast. A bit larger than I expected, but fine for recreational use.

Does the job on my motorcycle
Worked as advertised with my bike after a full charge. Recommend charging overnight initially; small enough to store in the rear compartment.

Looks and works well
Nice finish and clear screen. Buttons feel solid. I keep it in my backpack for commuting; it fills my e-bike tire reliably though it’s a bit loud.

Small but effective
Works fine, though the advertised 20s fill claim can be optimistic depending on tire size. Stops when target PSI is reached and is easy to carry.

Fast and simple to use
Inflated my 700x28 to 95 PSI in under a minute. Attaching the chuck to the Presta adapter was straightforward. Gauge accuracy seems reasonable.

Chuck E 5/5
Quiet enough and reliable
Used this multiple times to top off tires. Holds charge well so far; it slows as it nears the set pressure and isn’t unbearably loud. Compact and effective—would recommend.

Robert C. Hall 5/5
Tiny unit, impressive power
I wanted a small battery pump that actually works. This one is light and fits in my saddle bag. It quickly bumped my tires from ~20 PSI to 50 PSI in about 15–20 seconds and was simple to use.

Straightforward and dependable
Charged, attached to the tire, set the pressure and it stopped at the preset. Very compact and convenient to carry.
