I'm putting one of my cars in long term outdoor storage because of parking space shortage at my house. No nearby charging outlets near where I am taking it. It's the start of summer here in south-central TX. I've have a small Harbor freight charger with the windshield mount cups, and I'm sure it still puts out a charge, but I need something durable and cost effective where the panel plastic frame around it will not warp and melt in the hot sun. I don't want to roll the dice on a no-name SCAMAZON product, no matter how appealing they look, without a recommendation first. I want something durable. Anyone tried anything that holds up? Thanks.
