How long does the battery last and how long does it take to charge?
The built-in battery can last for 12 hours after a full charge. When the battery runs low, you should use a 5V 2A adapter, and it takes 4 hours to fully charge the battery. The device can also be charged with a 5V adapter or a power bank. (Page 2)
