Short version: does anyone have experience with the KFD brand DC Converter for the Airsense 10?
Long version:
We live in Texas, where the power grid has been somewhat unreliable lately and after a really miserable night without a CPAP, we wanted a backup option. He was using a Resmed s9 and after my research, we decided that step 1 would be getting his CPAP replaced since it was many years old and discontinued. I didn't want to spend $85 on a converter for the s9 that we were planning to replace ASAP, so I chose a battery option with both 12V DC and pure sine wave AC output that would work with or without a converter. I grabbed a Jackery 300 on sale for $270 (https://www.amazon.com/dp/B082TMBYR6/). We got the Airsense 10 today, so I want to get the DC/DC converter.
There is an aftermarket converter made by KFD available for $37. For the s9, there were only 32 reviews. They were good reviews, but I wasn't convinced. For the Airsense 10, there are 1000+ good reviews (https://www.amazon.com/dp/B07P6H994Q/). There are some bad reviews, but maybe half of those were from people who bought the wrong thing.
This will be a just in case item. We have no plans to camp or spend nights without power on purpose. The battery will be sitting on our bedroom floor while in use. We are indoor people.
If I really need to spend more than twice as much for the Resmed branded converter, I will, but I would rather not if the only real difference is the name on the box. I don't need the battery terminal connectors. We will still have the AC output available if needed. Trying to do a cost/benefit analysis here and some personal experience would help.
