Checking amp draw accumulations must be done with meters not by assumptions from reading an instruction book.
Inspiration cycle uses significantly more watts than expiration with a BiPap.
Use something like a Kil-A-Watt meter with the power brick connected to it. Multiply accumulated kWh fraction x 90% for a reasonable guess as to what to expect. A tubing insulation sleeve available from your medical supplier will SIGNIFICANTLY reduce humidifier accumulations because you will set the humidification to a much lower number.

Mex makes a good point on use of an insulation sleave for the tube. At least for resmed, they are inexpensive and reduce the need for tube heating and condensation. And along the way will reduce AH useage.
