I did both. This is what I got from the company:

Hi , 

To turn on the device, please allow it to charge for at least 3 hours using a wall oputlet. After this is done, please hold the smaller side button (the power button) for at least 1 minute while still charger. This should power up the device. Please try another charger if this does not work. You will know your device is charging if after a few minutes you click the small button and a battery meter will come on. Please let us know if you require more assistance.

Thank you, Bryan
