Last year in Spain it was hotter than normal for the time of year. So we ended up buying a few re chargeable fans that we can charge and run off our usb sockets. Great if you are not on hook up. Whilst certainly not as good air conditioning or even the roof vent fans the fact you can charge them whilst driving or on solar are great for off grid camping or even on a site with ehu. The ones I bought can run without electricity for 12/15 hours. Worth getting a couple in my opinion. Especially as it’s 33 degrees today. Too hot for me.
