20220620 SUP Car Valve Adapter Experiment

So as the video shows the inexpensive adapter bought on Amazon works absolutely fine.
However when mated to my small electric pump, the pump is not upto the job.
Presumably the dedicated 70 GBP+ pumps available on Amazon are speedier?
I'm going to keep the adapter and start off the inflation with the manual pump, then when I get a little tired swap over to the electric pump and adapter to finish it off.
