At 12 volts we found it draws between 350 - 500 mA (with heater on). However, hubby noted that these numbers are an estimate as he didn't leave his fancy meter on it - it was just an amp meter (or some such thing). Can you tell I didn't pay too close attention when he started to get all technical : )
Which model machine is this for?
The current draw varies with both the heater setting and the cpap pressure/flow. Could you please find out what the heater setting and the flow was for those two measurements? Was it done when someone was wearing a mask, or when the mask was open? I suspect there would be a big difference in current drain... Thanks.

Respironics M Series A-Flex, heater on 1, pressure around 7.
He said he'll do a better test and let us know his findings after our company leaves.
