I paid about $23 for it and it works as advertised. Fast and plenty of battery to inflate all 4 tires on my X7
I've had a couple cheap models and they were fine for filling tires occasionally. They clearly aren't heavy duty though.
The batteries often wear out fastest. I suspect they rebin the batteries that didn't QA for portable chargers, and those are ones that already failed QA for EVs.
I'd say at this point the reason they fail is well understood.
Hence I generally recommend non-battery units with a long DC cord. They last practically forever.
