UPDATE I was using the wrong nozzle, because none of the ones included fit the old Nemo valve. I emailed the founder (Tom Liggett) and he offered to send me one out, then learning I was in the UK and shipping would be $15, said he could send me the file to 3D print my own, or I could just clip the spokes from one of the other nozzles and use that.

With a better fitting nozzle I inflated the sleep mat fully in 4 minutes! amazing

This is incredible! My dad gifted me a Nemo sleeping mat, which is about the same weight as my 3/4 thermarest, but is full length and packs down much, much smaller

BUT it's a wholly inflating one, so I bought an Alpenblow Micro Inflator

This:
Weighs EIGHT GRAMS
Runs off your phone USB-C without eating any charge
Inflates the Nemo mat in 8 minutes, plus three big puffs from me

absolutely mind-blowing. Strong recommend - even at £60!
