I got the AliExpress one (to the UK), but wouldn't recommend it based on testing so far. It would only inflate to 60-ish psi before sounding like it really struggled, and managed this less than twice before conking out completely. This makes it less useful than the 2x CO2 I carried previously, so I'm not mega impressed. I've got it charging again and will report back if it miraculously gains capacity, but as of right now I'm struggling to think of a use case where I'd want to carry it.
