The 4 in 1 Wireless Charging Station is the perfect accessory for the office, home and travel. It is a great space saver and simultaneously charges up to 4 devices so you will never have to worry about running out of juice! Simply place your Smartphone vertically or horizontally on the station to charge. You can also charge your Apple iWatch and Apple Airpods in their designated positions. This station includes a USB port so that you can charge an additional device at the same time! A green indicator light will appear when it is powered on and a blue light appears when charging. If the device is not properly aligned, the blue and green light will flash. There are non slip pads on the bottom and a great imprint area on the base.
