Connect the USB cable to the power outlet and the charger unit.
Place one Pod on top of the charger and firmly press on top of them to make sure there is proper contact. If the indication light starts blinking red, move onto the next step. If the indication light changes between blue, green and red, leave the Pod on the charger for at least 10 minutes. Next remove the Pod for a moment, and then return it to the top of the charger and make sure the indication light then blinks red.
Add an additional Pod on top of the Pod currently charging and repeat the first 2 steps.
You can charge up to 6 Pods stacked one on top of the other.
