Slip · magnetic pack

Slip sticks to the back of a phone and charges it at 15 W without a cable, or at 20 W with one through the USB-C port on the edge. The magnet array is the strong kind: it holds the phone through a case and it does not slide down when you put the phone in a coat pocket. It is 11 mm thick at 5 000 mAh and 15 mm at 10 000, and we print both numbers because a magnetic pack that turns a phone into a brick is a pack you stop carrying. The face is a soft-touch silicone that does not scratch a phone back. There is a small folding kickstand under the magnet ring that props the phone at 60 degrees for video.
