Given 15 amp fuses blow their rating is probably close (it isn't in their interest to incorrectly spec it surely?)
I have an inline watt meter good to 150 amps here so I'll put it on for a nosey next time I'm at boat.
Yes i admit i did fail my physics o level so maybe was a bad observation ,however i do think if your just going to tube pressures your watt meter may reveal no real strain for the device and therefore considerably less current draw than the max ,if however your inflating paddle boards 15 psi or similar you will need lots of current ,the itiwit unit maxes at 15 amps but may not be as quick however have seen good reports for £40
