Powerenz, Inc. offers portable solar power systems that will provide power for nearly any brand or type of CPAP machine. For those of you who have not been able to enjoy outdoor and off-grid camping, wilderness travel, or any sort of extended stays in remote locations, our systems will allow you to enjoy those activities. To discuss how we can design a unit to solar power a CPAP machine to meet your unique needs, please call us at 770.639.2244. Before you call, it would be very helpful if you could tell us the power draw requirements of your CPAP machine, i.e. voltage, watts and/or amps, for how many hours each night you like to sleep, the location where you intend to use your system, and for how many consecutive nights you intend to need a system. If possible, it is more energy-efficient to operate your CPAP machine using 12-volt DC power rather than using AC power, so please try to find a 12-volt DC adapter or an automobile DC adapter for your CPAP machine. It is the single adapter that you would use if you were going to plug your CPAP machine directly into the cigarette lighter socket in your automobile.
