These Blushield Portables feature an on/off button, charging port, power indicator light, and battery indicator lights. Pressing the on/off button for three seconds will turn each of these portables on or off. When powering on, the battery indicator lights will ascend, and then go off. Simultaneously, the power light will illuminate, letting you know that the portable is currently on. While on, the power indicator light will stay illuminated for approximately 30 seconds, and go off for approximately 3 seconds. This pattern will continue as long as the power is still on. To turn off your portable, press the on/off button for three seconds until the battery indicator lights descend and go off. Simultaneously, the power indicator light will go off, letting you know that you have successfully powered off your device. At any time, whether the device is on or off, a short press on the button will illuminate the battery indicator lights to show the level of charge the battery currently has. 

When the portables are charging, the power indicator light will be off and the battery indicator lights will illuminate to the level of charge the battery has. Once the device is fully charged, all battery indicator lights will be illuminated. At this point, the device should be taken off the charger, to protect the life of the battery.
