Review on SONRU Car Windshield Sunshade Cover - Secure Fitting with 3 Magnets, Easy Installation - Waterproof & Scratch-Free - Fits Cars, Trucks, Vans, SUVs - 58'' X 46'' (Black) by Ronald Ingram

Kill two birds with one stone, this device is a USB mobile phone charger and Bluetooth FM that allows you to make hands-free calls or listen to music from your phone too car speakers. A small device that can bring my old bluetooth machine back to life, although the volume and sound quality could be improved. It is easy to install and easy to use. It can display real-time battery voltage status, which is a good feature.
