My wee Topeak one claims it can reach 160psi
Pump "maximum pressure" claims are usually rubbish. They connect a compressor to the pump and increase the pressure until something gives. Do this a few times, find the average, and that's what they put on the packaging and marketing.
However, I've got a Topeak Micro Rocket CB (not the T-handle version) and it works well. Got my 25mm tyres up to 95psi (tested pressure with track pump when I got home) which is what I usually put them up to.
Unsurprisingly nowhere near as quick or easy on the hands as a full size pump like a Zefal HPX, but it's perfect for lightweight emergency use.
