The Kangertech Evod USB charger is a high quality device with overcharge protection that will properly charge your 510 threaded battery. The 510 charger will charge all Evod batteries except the  Evod USB Passthrough battery (this battery must be charged using the USB port at the bottom). If your battery has a USB port refer to the manufacturer instructions, because more than likely it has to be charged through the USB port. Most batteries that have a USB port and a 510 thread connection should be charged through the USB port.

    Screw the top of the battery (the 510 thread) to the charger.
    The logo will light to indicate:(green/red) blinking light= charging or (green) light steady= charged
    If the light stays green after connecting a discharged battery to the charger, it could mean there is no contact between the charger and the inside of the 510 pin inside the battery thread due to the battery pin being pushed inside. Most of the times, this can be easily fixed by gently pulling the inside pin of the battery. For more details, please read: Fixing an Ego or 510 Battery
