The only things that I ever need to charge while we're camping are our phones, a tablet, and a portable fan/LED light. Since I don't need too much power I just use one of
these. I've been kicking around the idea of getting a portable fridge but am still on the fence since most of our trips are short enough to use coolers without it being a hassle. If we decide to go the fridge route I would probably get a Jackery power station and a solar panel. I've seen a couple of vehicles on YouTube and Instagram that have
these hood mounted solar panels. They seem a bit pricey but I really like the idea of making them look like some kind of hood wrap.
