Zus is a smart car charger device that not only charges your USB devices, but also helps you locate your car with the Zus app. When you need to find your car, just open the Zus app and walk in the direction of the red arrow to find your way back to your car. The app connects to the Zus device through Bluetooth 4.0. Therefore, a device with Android 4.3 or newer is needed to use the app. Besides being able to automatically save your car's location, Zus can also identify what device it's charging. It can then send the most optimal power and thus charge your device at its fastest speed. The two USB ports can output a maximum of 4.8A at 5V. This is enough to power two iPads or two phones simultaneously. Get two times the ports and speed with Zus.
