charges move controllers in about 4 hrs, navigation controllers in about 2.5 hrs. Light on controller blinks while charging, goes off once charging is done, can leave controllers on charger even when done charging. Unlike some other third party dumb chargers I've read about, where you are supposed to remove the controllers when done, from getting overcharged.
Small foot print
Uses two charging contact points, that touches the bottom of the controller, makes seating the controller onto the charger easy. Unlike most third party chargers, which uses a USB plug.
No USB port, Sony could've included at least one port for charging the dualshock controller
