Airshot is a tank you can charge up using a floor pump, foot pump or even a hand pump, and then use to deliver a blast of air into your tyre. Rather than having to buy a specific charger pump, which can be over £100, the Airshot is a more cost-effective solution if you already have a track pump. Another big advantage of the Airshot is its low weight and portability
The Airshot is slightly different option to the other best tubeless charging pumps on the market. It has a secondary air chamber that’s charged using a track pump. The twist is, you supply the track pump. Hence if you’ve already go one, it’s the cheapest way to get set up.
Charging is simple — connect your pump to the Presta valve at the top of the bottle and inflate. The outlet hose has a screw-on head that works with Presta valves, and even comes with an adapter that fits inside the valve stem — if you remove the valve core you increase the air-flow, which is handy for the most stubborn tyres.
It takes longer to charge the Airshot to 160psi than the other inflators, but it produces a big blast of air that seated all our test tyres. That said, we didn’t really need such high pressures for it to work — 100psi was usually enough. Nor did we have to top up the tyres afterwards, because a single charge inflated most tyres to over 35psi.
The big advantage of the Airshot is its low weight and portability, meaning it fits easily in the back of the car, and you can even charge it with a hand pump at a push. It’s also half the price of the JoeBlow Booster, and much less than the Flash Charger, although if you don’t have a track pump you will need to factor that in.
Watch how to repair a cut tubeless tyre
Our criticism when we tested the Airshot previously was that it kept falling over, and we said a wider or weighted base would be preferable, but we’ve since lashed the bottle to our workshop track pump using a couple of zip-ties. It’s a decent fix, but we’d like to see some foam pads and Velcro straps to do this job properly. We’d also like to see a longer hose, because once the Airshot is fastened to a floor pump, it’s too short to reach a bike in the workstand.
Compared to the inflators from Specialized and Giant, which have stands, handles and smart heads, the Airshot is pretty basic but it has some really nice details – like the Presta charge valve, which means you don’t have to swap your pump internals, simple valve core adapter and it’s a quarter of the weight. It’d be nice to have some form of stand or feature to attach the Airshot to a floor pump, but if you want a portable inflator that packs a punch this is the best out there.
