When your vape blinks a white light three-time it means that it is in need of a charge! Make sure the device is fully turned-off before plugging it in.
Simply locate your device's charging cable and charging port, plug the cable into the port and the port into a nearby wall outlet. Once you have done that, simply plug your device into the cable. Most batteries take up to 30 minutes to 1 full hour for a full recharge. After the time is up, simply unplug your device and it will be good to go!
