USB chargable portable battery bike tyre inflator: Looking for recommendation

I’m considering picking up a USB rechargable portable bike tyre inflator. My thinking behind it is that it should be easier to carry to the bike setup area of my next tri than a full-sized regular pump would be.

There are quite a lot of options out there on Amazon and AliExpress, but I’d much prefer to hear opinions from other TR users. A lot of the ones I’ve seen appear to use a Schraeder valve connector, and while I could use an adapter for Presta valves, it’s another level of complexity I’d prefer to avoid.

Does anyone have any good recommendations? I do vaguely recall them being mentioned on a podcast, but I’m not sure which one it was (and it could have been another podcast anyway!)

One I have seen, but not used myself.

Thanks! I did actually take a look at that one, but it seems a little pricey, especially when compared with some of the amazon or aliex ones.

If I remember correctly @GPLama has a video about one of the cheap ones of these and it was distinctly… underwhelming.

Thanks, I’ll have a look for it.
