The power cord for my Roku 3 is defective. It won't plug in to the Roku and there's NO support offered by the company to replace the power cord. Disappointing, to say the least, the company doesn't offer replacement parts for the Roku 3!!!!
Amazon lists several replacements claiming to be compatible with Roku3 (https://www.amazon.com/s?k=roku+3+power+cord), starting at about $7. I have no experience with any of them.
Roku 3 power supply requirements: 12 vdc power supply supplying at least 1 amp, connecting via a barrel connector, 5.5mm OD and 2.1 mm ID. (Information source: https://community.roku.com/t5/Remotes/Roku-Power-Supply-Guide/td-p/649284)
This describes a fairly common 12 vdc / 1 amp adapter that is used in a number of different devices, so adapters not specifically mentioning Roku 3 will work as long as they meet the same criteria. Pay especial attention to the barrel connector specs.
