Is Polyend Play battery powered?

Polyend Play does not have an onboard battery but it runs on 5V 1A so any decent power brick will allow you to power it up.

Depending on the workload, a basic 20K mAh power brick will let Polyend Play go on for long hours or even days.

Important: The Simpler the power bank, the better. Please notice that an "intelligent" power brick with advanced power management systems or even a "smart" computer USB out used for powering can cause issues and turn Play unstable. The best method to power up your Play unit is to use the original AC adapter.
