I have 2 fantastic fans from 2000.
All measurements with clamp on ammeter at the converter wire/fuse for each fan....converter was on with 1 new AGM 12 volt battery fully charged.
Front bedroom fan with temp control, bulb style. 4 amp fuse, 25 watt motor/5000RST
Low 0.8 amps 5.4 mph 509 ft/min
Med 1.3 amps. 6.6 mph 605 ft/min
High 1.8 amps 7.5 mph 700 ft/min
Rear fan no temp ctrl, 6 amp fuse, 36 watt motor/400R
Low 0.8 amps 6.1 mph 561 ft/min
Med 1.1 amps 7.6 mph 700 ft/min
High 1.5 amps 8.8 mph. 826 ft/min
I have no idea why the lower wattage motor is pulling more amps except that voltage drop must be in play since the rear fan is only a few feet from converter and the bedroom is a 20 foot wire run.
Update:
Edited after Mex made me run to the store to get a new 2032 battery for my wind speed meter that's been sitting in my toolbox for a few years. TP test is too subjective....single or double ply?
