I bush hog with my cabbed Massey Ferguson. In our hot, humid Virginia Summers, the A/C is nice, and the protection from angry Yellow Jackets when I run over a ground nest is also a plus. I like to listen to Spotify on my phone but it runs the battery down over the day. I just found this handy little accessory and installed it where my unused cigarette lighter was mounted in the cab. I had to enlarge the hole to 1-1/8" and change the lighter's wire connectors and she was good to go. The LED voltage meter is a nice touch but the charging feature is what is great. $15 on Amazon. Requires a 12-volt system.
