No USB Battery Bank Adapter to Drain Batteries?

[Vlaak]

One of my favorite things about my M2P is the little battery bank adapter that allows me to use the drone batteries as a USB battery bank. When I come back from flying I just charge up my iPad or whatever with any unused batteries from the day so they don't have to sit there full for several days until the DJI software discharges them. I don't see this in the M3 package and that is a bummer. Can anyone that has gotten the drone confirm whether this is in fact not included with the M3?

Thanks all!
