| Apr 23, 2018 at 13:33 | comment | added | R Thomas | Hi thanks for getting back. I'm 99% sure its 24V. This is the info I got from the net. Product Treatment pressure* (cm H2O) Current draw at 12 V DC (amps) Battery size for 8 hours use (amp-hours) 1.4A. | |
| Apr 23, 2018 at 12:48 | comment | added | Neil_UK | What voltage does the S9 VPAP draw its 1.4A at? If there's a DC-DC converter lurking somewhere, that would throw off your sums. Or maybe the 1.4A is a very generous maximum, or perhaps a high starting current, and the long term run current is actually much less? | |
