I recently purchased a Bluetti EB 150 solar generator. I am now looking for solar panels I can use to charge it. The panels won't be mounted on anything, like an RV or roof. They're just going to be something I put out in my back yard when the Bluetti needs to be charged. As an extra bonus I'd like to take them camping sometimes, so it would be best if the panels were luggable and not too fragile. I would love to hear recommendations. Also, MAXOAK, the maker of Bluetti, just came out with their own 120W panels and I'm wondering if anyone has an opinion about these. They're kind of expensive, but look pretty nifty.
