The NEW Ooze Smart USB charger is a rapid-charging compatible with all screw-on 510 pen batteries. This little guy protects your pen against overcharging with its auto shut-off feature. The light on the charger will turn green when your pen reaches full charge, and it will stop sending power from the outlet so it doesn't get burnt out. A must have accessory for all Ooze pen owners!
