When the LED flashes red 10 times, it's time to charge your vape device. Your Vuse ePod 2+ vape battery may run out before the pod is finished, so don't automatically discard the pod when charging the device.
Your Vuse ePod 2+ device will also light red/amber/green after each puff to show you your charge level. When the level changes from green to amber, or amber to red the device will vibrate to let you know.
