Edit: 1x USB Mini, 1x USB-C, 1x USB-A (boo!)
At least the USB-C is bi-directional but the wasted space for the mini is annoying.
Wireless charging with magsafe is great, but has an unwanted effect of reduced efficiency. A rule of thumb that has served me well: a typical power bank can provide about 2/3 of its full capacity as useful output using a wire. Depending on coil quality, proximity, and alignment, wireless charging can consume anywhere from 15-80% more energy to provide equivalent charge output to another device when compared to wired charging.
Some napkin math: I expect a 10000mAh power bank to reliably provide at least 6000mAh of useful charge using a wired cable. That's one full charge from 0% to 100% on most modern smartphones with some juice leftover. Using wireless charging, I may end up depleting the entire power bank without ever giving my phone a full charge.
