The obvious difference here is that while the Airshot tank can be used with any pump, the Bontrager combines pump and tank in the same package. That’s a great idea in principle and potentially more convenient for transporting. It makes it a heavy, bulky piece to lug around though. Having already accidentally broken the hose attachment point once, its largely plastic construction is proving less robust than the metal fixtured Airshot too and obviously if the pump breaks you can’t use the compressor and vice versa.
The good news is that it actually works really well in terms of popping tubeless tyres onto rims and sealing them in a single hit, with only the baggiest set ups not quite sealing first time and needing a frantic pump thrash to complete the job.
There’s no way of separating compressor tank and pump though, so you have to pressurise both to the required pressure if you’re starting from zero psi, and the small volume pump means it takes a very long time.
It’s not so bad once you’ve got the tank pressurised and keep it that way, but if you forget to close the release valve again before you pop the valve head off the valve, you lose all the air in the tank so you have to start it all over again – which is really frustrating.
