One two-way USB-C port and a magnet on the back
The power bank has a single USB-C port that works as both input and output: it recharges the power bank at 5, 9 or 12 V and charges a phone at up to 20 W. According to the manufacturer, the magnetic back attaches to the iPhone 12 and newer models and charges them wirelessly at up to 15 W. The LEDs show the charge level and the mode.
