EcoNour Car Window Screens for Camping (Pack of 2) | 100% Protection from Bugs, UV and Mosquito Net | Breathable Mesh Baby Window Covers for Privacy Blackout (Medium 16"x30") | Car Window Accessories

I just bought some nets already sowed into a pouch designed to fit over the door. Something like this from Amazon (I didn't get this exact one, but essentially this) https://www.amazon.com/EcoNour-Protection-Mosquito-Breathable-Blackout/dp/B01M4NRZAG

I don't know what all you have access to, but I use these against bugs. You put it over your door and then roll down the window. Also, there are batteries with solar chargers you can use to maintain your phone.https://a.co/d/07E0RQ4Y
