AC adapter question

I have a Roku 3 and have the opportunity to upgrade to an Ultra 4640 but its missing the AC adapter and cord. I have a suspicion the one from my 3 will work though I want to make sure before getting the Ultra..Anyone ever tried swapping to see if it works? Thanks

Re: AC adapter question

Hi there! Thanks for reaching out regarding your question.

If you're using the power adapter PW09XB from the Roku 3, it will be compatible with the Roku Ultra 4640.
