Weldtite Jet-Valve Tyre Inflator with Air Canister

This inflator works really well: after opening I was able to use without instructions and inflate two tyres with one canister (I've never used an inflator before). Inflation can be controlled by easing off the pressure applied to the inflator against the tyre valve.The plastic cover is a bonus as it protects your hand from the eventual freezing canister.

Always used a standard pump before but this device has got me out of trouble more than once. RecommendedProsMuch smaller than a pump.Seems reliableEasy to useCheap compared to many such inflatorsMuch quicker than a pump.Fits both Shraeder and presta valvesMore robust than a pump (fewer working parts).ConsInflates so quickly that it can be difficult to control the inflation.Spent air canisters are a waste product.

I bought this to make recovering from a puncture less time consuming (I still carry a pump as a backup!). I have had very few punctures, but as I was taking part in a 100 mile sportive event I figured “better safe than sorry”.I did have to use the CO2 type inflator and it was amazing – really simple, easy to use and it inflated my tyre to a high enough pressure that I completed the sportive without further issues.I am a complete convert to this light weight, quick and simple way to help re-inflate a type after changing due to a puncture.The CO2 cartridges can get really cold, so the light weight plastic cartridge cover is a good idea to ensure your hand is not in contact with the metal cartridge when used.Get one, you’ll not regret it.

looks a quality Product, works well is easy to use, the only "thing" is that one bottle of co2 is for one tire only , so it comes to be expensive

Used it twice, thought it was fantastic - a very quick and convenient way to inflate your tyre.The third time, BANG! as it exploded in my hand with the orange rubber piece flying out. Hmm I thought, I probably didn't have it put together firmly enough. Reassembled it, checked it, looked fine, gave it a try. BANG!Gave me quite a scare and its now in the bin and I still have a hand although it feels like I'm missing an eardrum. Now looking to buy a more robust alternative.

I have only tested this out so far to see how much pumping it was possible to do. I have road 25' wide tyres which I like to keep at 100psi.This was able to pump one of my tyres up to around 90psi so I suppose that would be okay to get me home, but you'd have to change the bulb to get more pressure - and how would you know what the pressure was anyway if you did change the bulb and try to put more in?Clearly there are limitations, but it fits in my saddle bag, pumping up a tyre is almost instant and effortless and I haven't had a puncture yet anyway so the honeymoon period continues.

Fits nicely in repair kit under bike seat - Used a number of times by the road side, works great, but one canister not quite enough for chunky off road tires. Normally carry 3 canisters along with inflator to be on the safe side, but still a lot smaller (and more fun) than carrying a pump.

Very compact and the build quality feels good. I've used the screw on types previously and the jury is still out as to whether I prefer that or this push valve. This is quicker, but the screw on type feels a bit more controllable.
