The Coospo X1 Electric Tiny Bike Pump is very concisely named, as least once you get past the bit that sounds like an intergalactic android and into the descriptors. It is indeed electric, tiny, and a bike pump. And those things are good. Mission complete.

Coospo positions this as an alternative to CO2, and I think that’s a good way of looking at it. It provides a few quick and easy shots before running out, and while this pump is a good deal noisier and a little bit slower, it’s at least going to warm your fingers up rather than freeze them to a cylinder.
This is pretty impressive for such a small device. And though it doesn’t last long – blow up two big gravel tyres and it’s done – it’s also quick to recharge. A 15-minute charge is enough for it to do one tyre, while a full charge is only a claimed 40 minutes (actually two minutes less).
I managed to get one 45mm gravel tyre on a 23mm rim to 60psi and a second to 50psi on one full charge. It even managed to restart from 50psi with the final battery light (of four) flashing and the voltage dropping perilously low.
The pump always sounded a bit lethargic to me by the second tyre, but the timings were actually very similar. It took 1m 58 seconds to get each of those big 45mm tyres to 50psi. Obviously the smaller the volume the quicker it fills them, but as you’re going to higher end pressures it’s not massively quicker. Going from 0-60psi in a 40mm tyre, for instance, still took 1m 45s.
It’s also very loud – it seemed almost the volume of an idling, small-capacity petrol engine to me (think chainsaw or strimmer), but it’s probably a few decibels short in reality.
It gets warm, but never uncomfortably hot. In fact, after taking the first 45mm tyre to 50psi the valve chuck was warmer than the pump body; by the end of the second tyre that was reversed, but there are no issues with handling it (unlike a frostbite-inducing CO2 bottle).
Despite wasting so much energy as heat and noise, this thing gets enough work done to reinflate you after at least two punctures (pretty unlucky for one ride), and that makes it useful. You can easily swap between valve types by reversing the end of the chuck, too. Maximum pressure is 110psi, and there’s a needle for inflating sport balls. Did you watch the sport ball, by the way? How about that goal? Shambles.
While the short life of the 500mAh battery means it isn’t a real replacement for a regular pump, it is a very good replacement – at least for non-racers – for CO2. At 143g it’s very close to a pair of cylinders and a CO2 head (my combo weighs 127g), it’ll inflate at least as many tyres (probably more), and it’s similar for overall size and volume too. The Coospo is just a little thicker.
Perhaps the real difference is that CO2 devices are purely mechanical, whereas this pump relies on electronics. The electronics are simple – the screen shows the current pressure, the plus and minus buttons change the target pressure, and that’s it – but they’re still electronic.
And there’s no weatherproofing. While it’s small enough to shield with your hand in pouring rain, it’s not something you want getting damp in your bag or jersey.
It’s also a shame there’s no way of securing the removable hose to the pump body to stop it getting lost – not even a rubber band or a Velcro strap. It’s another reason to stash this in a Ziploc bag, like I do when I’m playing sport ball.
Value
At £78.77 this is very competitive, but in reality that price (as its random nature suggests) drifts about according to exchange rates, and even then it isn’t really real. For instance, when I checked back it was £79.08, and ‘reduced’ to £55.32. Fully 70 percent of the products suggested beneath the X1 on Coospo’s site had significant reductions; it’s that kind of pricing model. You’re unlikely to pay full price.
Still, we have to compare things at RRP or it all gets a bit silly. At full price the Coospo is very close to the £75 Muc-Off AirMach Electric Mini Inflator, but that has no screen or gauge, and you can’t set a target pressure. That’s a bit weak given the competition.
The Coospo is cheaper than the £80.72 Cycplus AS2 Pro Mini Bicycle Tire Inflator, the Inflata Pro S and the £99 Prestacycle Prestaflator Go too. They’re all still very good, however, and more competitive on spec.
If electricity is still just too new-fangled and maybe even woke, you could get a CO2 head instead for £15-£20, plus around 60 cartridges such as these from Ico on Amazon. They should last even the unluckiest cyclist a very long time. In fact, if you just line them all up inside your tyres they can NEVER go flat! My god I’m a genius. Somebody elect me.

Overall
This is a great entry to the fast-expanding tiny electric air-huffer market, especially if you catch it at a reduced price.
