Re: Battery solution for HDM Z1 CPAP offgrid (backpacking, camping) usage
Can you say where you found the information that "The HDM Z1 requires DC 15V to provide treatment". Obviously it is working fine with the 15V PD regulated input, per your own experiments / experience. I am just wondering where the optimal / supported input voltage is specified. I can't find anything...
