I built 3 portable battery boxes out of the NOCO group 31 battery box. its wired to 3, 15 amp plugs, circuit breakers and a simple volt meeter. these boxes can power a oxygen concentrator, c-pap, 12 volt engel fridge. it will charge all computers and power anything with 12 volt power. USB plugs into the 12 volt socket to charge small computers. if I need the inverter. it plugs into the 12 volt box too. my battery is a lithium 100 amp battle born. I have 3 of them. all batteries are monitored with a victron smart shunt. what's nice about my system. if I need more battery capacity. I can add a bigger battery like the lithium big battery 200 amp. all I do is plug it to the group 31 box with an Anderson 50 amp plug. all batteries are charged with a blue smart 20 amp victron battery charger. for what I paid for my system. its worth it. I built it with quality parts. my battery lays in a group 31 box with the smart shunt. my portable box with the 12 volt plugs and inverter sits in another group 31 box on top of my battery. I plug it to the battery box with a Anderson plug. when its time to charge my battery. I disconnect the Anderson plug from the battery. plug the battery charger with a Anderson plug from the charger. my Yamaha generator supplies my power. I also have solar too. if your handy with electrical. build one yourself. they are much better than those commercial boxes.
I thought I was reading that with my particular airsense 11 there was no adapter yet and that it uses 24v. From what I have gathered this particular adapter would make the whole thing more efficient if/when it becomes available?
I want to be clear-the more I read the more I think I don't want to blow up my precious new machine and do not trust myself to make my own. Maybe one day I will learn but I have had it a month and it is literally a life saving device for me.
I appreciate all that folks have posted here to help, but am thinking the ready made are probably the way to go.
That said, Rob I think mentioned the Maxoak but did not reply yet as to which one he uses (I am sure he has a busy life but I am hopeful). That looked like they offered several decent options.
I also looked to see what Rav had to offer. I know they make a good product and while they don't make the one he linked anymore they do make these:

I dont know how it compares to this renogy:
https://www.amazon.com/gp/product/B0791WDZTW?th=1 but they appear to have similar specs? which doesnt seem right since the renogy is so much smaller.
So I come back to wanting to know if I can get 2-3 days from any of these, can solar or wall or car charge, and if the type of battery is good. I dont want the lead acid type.
i really want to be ready for winter. We often lose power and sometimes for extended periods. I don't want to lose my lifeline and it makes me very nervous.
Thanks in advance for anyone patient enough with me to respond.
