The cost recently at Amazon (currently out of stock) was $460.
Hmm, spider sense is tingling here.
Not sure about your spidey sense - since it isn't currently available on amazon.com I had to refer to this review:
https://mysolarhome.us/jackery-500-vs-k ... power-500/
It does appear that with the current exchange rate, the Canadian version is much cheaper. Curiously, there several identical looking units from different brands that are cheaper but have less power - I'm not sure what's going on there.
I was surprised that a 12V socket was not included, its an extra. Also, one of the reviewers complained about low voltage on the 12V output; this is probably not an issue for most cpaps, but it could be a problem in some applications.

The lower power sku does not have the the jumper cables option.
Some claim modified sine wave and some claim pure sine wave.
I suspect they are all modified sine wave.
Will try to get access to a RMS multimeter or spope this week to verify.

To use the cpap machine with dc I would have to purchase this

and this

Which is another ~$140CAD.
Its not clear to me if I can draw 10A from one socket or 3A per socket(4x dc sockets) with an aggregate of 10A.
I wonder if a new sku may come available with the cigarette ligher socket in place of the jumper cables option.
It would be cheaper for them and the reviews show that people notice the absence.

They seem to be tight lipped about the weight, maybe they don't all have the same batteries in them.

Wonder how much it would cost for a Drone carried Gen set.

Yes, I understand the meaning of OEM. The question is, is Chafon the OEM, or are they simply slapping a label on someone else's gear? When see products where the actually manufacturer can't be determined, it often means poor support. Also, if three companies are claiming 288 WH, but Chafon is claiming 346, someone might be stretching the truth.

The 12v socket would be a mandatory accessory for me. The 12/24 DC converter effectively almost doubles the available juice in the battery - this is especially cost effective with a pricey Lithium pack. I would think anyone running a ResMed from a battery would want to get one.

If I could run 2x s9's with humidifiers off one chafon 346WH unit for > 9 hours then I would be more interested in paying the additional $280.00.

Yes, I appreciate that you have specific requirements (which I don't quite understand). But you've already made your decisions; I try to address the concerns of future readers who might be considering this device. Clearly, if one chafon exactly matches your needs, then squeezing a few hours more out of it doesn't matter much. But if you need a higher pressure, or want to go two nights, it makes a huge difference.
