I'm looking for suggestions on how to power my CPAP machine when I'm camping. I currently have an Anker 200 battery with a solar panel and a CAT CJ1, but I'm not sure if this is enough. Does anyone have advice on battery or solar panel setups that would work well for CPAP use in the great outdoors?

It really depends on the model of your CPAP. I have an older ResMed that only takes AC power. I use an Ecoflow River 3 which runs my machine for a full night. Make sure to get a solid solar panel (at least 200W) for recharging, and turn off the inverter when not needed to save battery!
Check if your CPAP machine is compatible with a 12v DC power supply. If it is, you could use a rechargeable battery or even the cigarette lighter from a solar inverter to keep it powered. Just make sure to get the right cords!
Do you actually need solar power for your setup? If you’re okay with a bit of weight, I’ve been using the Growatt Vita 550, which can handle AC and DC outputs. It's got good storage and is safe for camping. You can find it online, and it might suit your needs really well!

Definitely worth double-checking, as many CPAPs use 18v or 24v. Make sure to look into your model's requirements to avoid any issues!
