Review on OKiT Car Charger: High-Speed 4-Port USB Multi-Port QC3.0 Rapid Charger for Android/iOS Smartphones & USB Devices by Kyle Rock

It does exactly what it was designed to do. 4 USB ports Ideal for 2nd row seating. With your car you can charge 4 devices at the same time. It's a smart device that recognizes what you have plugged in and then delivers the maximum charge appropriate for each device. This device worked great and gave everyone in the car the ability to stay charged without having to wait in line to charge. I can only recommend this wonderful device. It's well built and engineered to work.
