That’s the big question. If you’re out camping for a weekend and just want to keep a tablet charged to watch movies, something light and without a ton of capacity will be just fine. More serious off-roaders or anyone spending long stretches off the grid will need something more heavy-duty. Road trippers in an RV may find something in-between works best. Think about what you’re going to use a power station for, and where possible keep in mind the specific amounts of power you might need to make the best choice.
