The Premium EGO batteries have been introduced to provide more power to the smokeless experience. It only makes sense that a powerful battery is accompanied by a powerful charger. The EGO USB charger was subsequently developed to supply the battery with a higher level of source energy. The charger can be used independently, by virtue of its USB connection, on any device with an available USB port. Additionally, the EGO charger is compatible with the AC adaptor and the car charger, increasing the adaptable features of our accessories section. The charger’s USB indicator glows red while it is charging and green when it is sufficiently charged.
