I am really needing a replacement ac adapter for a Roku Ultra 4670X. I am not seeing an option in accessories though?
Is there a authentic ac adapter that is compatible that works with Roku ultra 4670X?
You want the PW11 listed on this page under the remotes:
https://www.roku.com/products/accessories/player
It states on that PW 11
Compatible with: Roku Ultra LTRoku Ultra (Only model 4660, 4661, 4760, 4800)
The suffix doesn't matter, the roku by itself has x on it, where roku, accessories, and box have r or rw if bought at Walmart, they are all the same.
