Re: Roku Power Supply Guide

Roku 2710X  and Roku Premiere 4620X


What does the suffix X in the model number indicate?

These units require a power adapter with a small barrel.  Does anyone know the specifications of this plug?

Re: Roku Power Supply Guide


The suffix “X” following the model number indicates the Roku device unit itself.  Nowadays, this is the only indication of the suffix, with “R” (which indicates retail stores) additionally indicating the packaging for the Roku or its accessory.  Ten years ago, the “X” suffix additionally indicated online stores, whereas retail stores were the only indication of the “R” suffix.

The list of suffixes and its indications can be determined on this topic here:

I’m into videotapes and old electronics stuff, including extenders, converters and analog 4:3 TV sets (which are obsolete these days), and Miss Bianca is my favorite character in Disney’s The Rescuers (1977) and its sequel, The Rescuers Down Under (1990). I am not a Roku employee, only a user like you. ~ Jordan

The barrel jack size listed for the 2710 does NOT match the adapter I needed to use for the 2710X, I needed to use a 4.0x1.7mm jack.

That wasn't the only error.

Last pulled from an Excel file (quite a while back), It was pulled through corrupted on numerous models.

Appreciate the heads up!
