Portable lithium power source - Input and advice

[Freeman]

Still relatively new to travel in a motor home, advice and input from seasoned veterans is always welcomed.

Since we bought our Greyhawk, when we travel we have made reservations and stayed at various Harvest Host sites for two or three days and then stay at an RV campground/resort with full hookup for three to five days. While at the Harvest Host sites, etiquette is not to run the generator after 10:00 PM. This has worked well. Even with the heat of summer, the temperatures drop in the evening and we sleep nicely with the windows open and a portable fan.

The issue is that I am not using the CPAP as I should on the Harvest Host nights. I recently read an article about a portable lithium power source. A little research revealed a number of companies with a number of models with many features.

Any thoughts?

I looked into a lithium battery pack for my cpap. There were a couple models to choose from but all were in the ~$350 range. For $25 I got a 6-foot 12V accessory adapter instead so I can run it off the trailer batteries. I run my unit with the humidifier off when using the trailer batteries which helps reduce the load. So far this has been working out well and I'm not missing nights when on the road or without shore power.
