Samsung S6 Edge Battery Case,VEGO 2015 Newest 4200 Mah Backup External Battery Charger Case For Samsung Galaxy S6 Edge Rechargeable Power Bank Case,Portable Backup Power Bank Case with Kickstand - Black

Received the unit on 1/20/16 and the first thing I noticed when charging is that the USB port is NOT properly fitting for the entire plug. Somehow the placement and spacing of the USB plug in the bottom of the charger is "recessed" into the case so if your not careful the charging cable will continuously fall off the charger case. Maybe the design needs to make the usb port more "flush" to the surface for a good solid connection, but the spacing does NOT allow a snug connect for charging.On another note ...the Galaxy S6 "FAST" Charge is prohibited when using this charger case. It only trickle charges the unit. It took over 4 hours of no-use charging just to charge the phone battery and charge battery from 50% to full using the phone and case together. I find for speedier charging times, I must separately charge my S6 alone, minus the power case and separately charge the power case standalone simultaneously. Samsung FAST charge only works when the S6 connects direct from the power receptacle with no power case inserted in between.
