Well ... I paid ~$400 for the Bluetti on a Black Friday sale:
1) Instead, I would have to have installed/wired a 12V DC recepable back by the rear bed, which would have been a real pain (I have higher payback things to do with my time).
2) In addition to 1) above, I would have needed to buy a 12V DC to 20V DC upconversion adapter (medical grade - for failure-proofness at ~$130) to power the CPAP machine.
3) Sometimes our family group campouts have their outside evening camp fires too far away from our rig to run the long extension cords from our rig necessary for powering heated throw-blankets for us.
4) The DW and myself didn't know what other Christmas gift(s) to buy for ourselves, anyway. :B
P.S. #1: So far during my in-home testing of the 537 Wh Blueitti it has powered a CPAP machine for 4 nights - while consuming only around 35% of it's LiFeO4's stored energy.
P.S. #2: It's ultra-safe LiFeO4 lithium battery electrochemistry is way safer than me trying to make my own more dangerous-to-use-in-confined-spaces Lithium-ion, or LA, or AGM portable concoction.
What you're saying is, sometimes it easer to just to buy what works. I agree. I did a similar thing but bought an EcoFLo 2KW unit and when I saw a good sale but a second 2KW add on battery. I can use them in our B or as backup for short power outages for our house so I don't have to get the Honda out. Sometimes spending the money and having a well engineered and packaged product is better than saying I could build it cheaper by piecing it together.
