power adapter sizes


My power adapter broke and I’m trying to purchase a new one, but first I need some specs.

What are the proper barrel sizes for a power supply for the ud-3900, ud-3000, and ud-160-a?

can I get the same power supply for all 3? Are there differences?


Hi Jacob,

The UD-3900 and UD-3000 share a common barrel size: 4.72mm / 1.6mm

We sell refurbished OEM power adapters for those models on our eBay store page here:

The UD-160-A has been discontinued for awhile so I will have to look and see what power adapter(s) would fit. If you still have your UD-3900 power supply, can you see if it will fit the UD-160-A?

You can contact us directly at support@plugable.com for faster response.

Thank you,
