          I've had my Phoozy for years. During that time I moved back up north. As you know cold weather zaps a phone battery. I like to listen to music when I'm hiking, even when it's well below 32 degrees. I'm amazed at well the phoozy keeps the battery from draining. I've compared it to friends who don't have one. They are amazed too after our hikes. Their phone often goes down to zero during the call. I know it works in the heat, but in the cold it's unbelievable. Thanks
