LG V20 Charger Dock Cradle, LG V20 Charging Station, Slook Dual Desktop Dock Charger with USB Cable-Support Charging Spare Mobile Cell Phone Charger Dock for LG V20

Used it a couple of times it seems to charge faster when I have my phone turned off I have not used it yet for the spare battery but when I have my phone turned off to charge it charges very quick overall satisfied

DOES NOT CHARGE THE BATTERY TO 100% I'VE LEFT MY SPARE BATTERY IN THE CHARGER OVERNIGHT AND THE MOST IT CHARGED TO WAS 91%

Good

Not charging battery when phone is in dock. Possible bad unit? Fast charging supported on phone, doesn't seem to work on battery
