I have one to run my wifes cpac. We are off grid at our cabin. It works fine but only lasts about 2/3 of what they say it will. So if you get one DOUBLE what you think you will need.
Like for a cabin or a tent trip? 2 very different types of systems.
I brought a foldable system on a recent 9 day trip into the Scapegoat. It was purchased for me to us so not sure if the brand is any good but it is a PowerFilm 30Watt. It worked great for charging small battery packs but google says they are spendy
