I have the ~80GB "full english" snapshot I grabbed some time ago and use with Kiwix. It's not quite "full", it doesn't have quite all images and video, etc. But the size is still reasonable for a desktop/laptop PC.

I also have a 10GB snapshot on my phone, but it's a bit lacking. I don't have enough storage on my phone to fit the bigger one. But a battery powered offline Wikipedia is high on my list of necessary things in case things go south.

I haven't found a great way to keep these synced up, glad to hear if someone has a good solution for up-to-date offline wikipedia.
