A 12V compressor is the right tool for airing up after a track, but it’s a lot of gear to dig out when one tyre is a few PSI low. The Bosch EasyPump is the small alternative: a cordless air pump the size of a torch that charges over USB-C and stops by itself at the pressure you set. We paid $120 for it and tried it on the Prado’s 265/65R17 tyres.
What You’re Getting
The pump has a built-in 3.6 V battery, a 24 cm braided hose with a brass screw-on connector, a display and an LED light. In the box are a Presta (French) valve adapter, a ball needle, a volume adapter for inflatables, a USB-C cable and a fabric drawstring bag.
The adapters store inside the handle, under a clear cover, so they’re always with the pump.
The good
- Cordless, and charges over USB-C
- Stops by itself at the set pressure
- Display shows preset and live PSI
- Adapters store inside the handle
- Small and light: 293 g on our scale
- Brass connector and braided hose
The not-so-good
- Slow on 4WD tyres
- Not for airing up after a track
- Pricey at $120

Display and controls
The EasyPump is simple to work. The red button switches it on. The display shows two numbers: the pressure you’ve set on top, marked PRESET, and the live pressure underneath. Plus and minus buttons change the preset, a UNIT button switches the unit, and START/STOP does what it says.
Screw the connector onto the valve and the display shows the pressure that’s in the tyre, so it works as a pressure gauge too. Press start, and the pump runs until it reaches the preset and then stops by itself. You don’t have to stand there watching it.
On 4WD tyres
This is where you need to know what the EasyPump is for. With the preset at 36 PSI, we put it on a 265/65R17 tyre at 30 PSI and ran a stopwatch. After about five and a half minutes it had reached 35 PSI. That’s roughly 1 PSI a minute on a tyre this size.
For a top-up of a few PSI on one tyre, that’s fine: connect it, press start, and do something else while it runs. The AstroAI 12V Car Tyre Inflator took about two minutes to reach 36 PSI on the same tyre. For airing up four tyres from track pressures the EasyPump is far too slow, and a 12V compressor like the XTM 160 L/min is the tool for that job.
On smaller things it has an easier time. Bike tyres, balls and small inflatables hold far less air than a 4WD tyre, and the adapters for them are in the handle.
Size and weight
The EasyPump is 21.5 cm long and weighed 293 g on our scale, so it fits in a door pocket, a glovebox or a drawer. There are no cables to the battery and no need to open the bonnet, which is the whole point of it: it’s the pump you’ll actually grab for a quick check.
Because the battery is built in and charges over USB-C, it can be topped up from the car or a power bank on a trip.
Conclusion: Bosch EasyPump
The Bosch EasyPump is a small, cordless air pump that’s very easy to use. It charges over USB-C, shows the live pressure, stops by itself at the pressure you set, and keeps its adapters in the handle. On 4WD tyres it’s slow: 30 to 35 PSI took about five and a half minutes on a 265/65R17, so it won’t replace a 12V compressor. I paid $120 for it. For top-ups, bike tyres and balls, it’s a handy pump to keep in the car.
A cordless, USB-C air pump with a clear display, preset pressure and autostop, at 293 g.
It’s slow on 4WD tyres (about five and a half minutes from 30 to 35 PSI), so it’s for top-ups, bikes and balls, not for airing up after a track.
- Car campers
- Travellers
- Everyday carry
Yes for top-ups, bike tyres and balls, if you value having no cables and a pump that fits in the door pocket. No if you air down for tracks and need to pump four 4WD tyres back up: get a 12V compressor for that.
