This is a great addition to my drone kit. I have 2 batteries for my Mini 2 and charged them with the drone first but quickly got tired of taking the drone out and changing batteries to make sure I was ready to fly again. This charging station allows me to connect both batteries and safely store the drone in my bag and easily prime both batteries. Both batteries charged from 15% to full in about 2.5 hours using a 15W charger. I didn't time it exactly because that's the point for me - tune in and go!
