Let's assume WebSiteCompany (WSC) is honest and knowledgeable. Assume they say on their web site that the A10 works OK on an inverter.wm_hess wrote:From reading that, it appears that an inverter can be used to run the device?
Is WSC going to replace your A10 machine if it is damaged while using an inverter?
If your A10 machine quits working while being used with an inverter, is WSC going to decide they steered you wrong and replace your A10? How do you know the A10 died from the inverter, and not for unrelated reasons?
How do they know it was damaged because of a general problem with using inverters, or could the problem be that the inverter you used was defective?
Are they going to replace your A10 machine if you used an inverter because of their web site, but didn't buy their battery?
How long is it going to take for them to decide that they were at fault, even if they do? Are they going to want you to send them your A10 machine and the inverter so they can test them and evaluate them?
If you use an inverter and your UPS fails for unrelated reasons, will ResMed deny your warranty claim?
The ResMed converter is expensive. Inverters are easily obtained elsewhere, and can be used for devices other than CPAP machines. Many people already have inverters.wm_hess wrote:If I may ask though why would you want to use an inverter instead of a converter? Doesn't a inverter use more energy than a converter, thus draining a battery faster?
UPS's can power your CPAP full time and automatically fall back to battery usage when the power goes out. UPS's use inverters. If the A10 won't work on inverters, it won't work on a UPS, either. Most home generators use inverters.
ResMed owes it to their customers to tell them what forms of power will and won't safely power their CPAP machines. Especially since they do give out SOME information about running off of battery power.
If an inverter WILL damage the A10, they owe it to their customers to inform them of this. I consider it to be a design flaw.
By the way, Philips Respironics doesn't publish any information about running on battery. I'd be happy to be proved wrong on this, but I haven't been able to find it.
As I said, I expect it's OK, but it's possible that it can damage the machine. ResMed should update their battery power information page to say yes or no for the A10 machines.
