Came into this a little late, but I have the Mophie mod...
1- yes it has a usb-C charge port, and it is very happy charging from a Moto Turbo Charge adapter (I have the one with the phone and bought an extra). No wireless charging, but you can charge off wall adapter, car adapter, anything with a USB-C, no wireless pad needed.
It WILL also charge connected to the phone. IF you use a 'standard' charger, the phone will charge first (while showing "Waiting to Charge Mod". After the phone hits 100% and a few minute delay, it will divert charging to the Mophie), IF you plug into a Turbo Charger it will charge them simultaneously. What I have found is that if you want to charge it connected to the phone, plug the PHONE into the charger, not the Mophie. The phone circuitry handles sending power to both units.
2- yes, the stats integrate into the os (it shows on the battery page as well as the 'Command Center' widget wing
3- I will say that the leds are NICE to have, as you can hit a button on it and get a general idea of charge without having to plug it into the phone (as when you are using another Mod on the phone, and want to check the status of the power in the Mophie)
It has a slightly larger battery than the others and I actually like the design on this one a little better than the more rounded design of the others.
If I missed anything, just ask.
