Is the Tracker battery powered?

Polyend Tracker 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 Tracker go on for long hours or even days.

Important: The best method to power up your tracker is to use the original AC adapter through. 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 your Tracker unstable and funky.
