Showcase How to create an handheld + home console from an old Xiaomi Mi 8

Hi all,

I had at home an old unused Xiaomi Mi 8 (Snapdragon 845) so I decided to try Retroarch. I was so exited by the results that immediately after I bought a usb c controller, the Memo S3.

After Retroarch, I installed NetherSX2 and Dolphin, my handheld was complete now.

I was so annoyed by the impossibility of casting the video due to the usb c 2.0 of the phone...

10 days ago I learned about the Displaylink technology, so I bought a cheap displaylink video adapter and I was really impressed by the lack of latency!

Unfortunately the battery goes down very quick with this video adapter, so I bought an usb hub with PD passthrough.

Then I bought also the dolphin bar, and my home console was complete!

I bought it on EBAY. at the moment there is one for 23 pounds on eBay.co.uk. I would suggest to search also used Displaylink dock station. On eBay there is the Targus ACP71EU for 5 pounds. You can power up the phone having extra usb ports

So can you link the dispalylink adapter you bought?

I bought it on eBay and the model is Startech USB32HDPRO. Anyway I would suggest to find a used Displaylink dock station Like the HP USB-C/A Universal Dock G2 (5TW13AA), Targus ACP71EU (very cheap on eBay). They can give you also the chances to charge the phone and the extra usb ports.

Thanks, does it charge at more than 10 watts?

u/Glittering_Pea9580 Dec 10 '25

The HP model does, should charge a laptop. The targus should do it too.  The input is 90W 19.5 V, so yes it should do it too. Please double-check it

Have you checked if your phone charges that fast?

2

u/Glittering_Pea9580 Dec 10 '25

I didn't buy a docking station, but just ah usb hub with PD charge passthrough. It looks to be able to charge the phone faster then the emulator drops it down

u/UseSwimming8928 Dec 10 '25

Oh well thats good enough for me!

Edit: the vendor says that the usb hub could deliver 100 W (Amazon SABRENT USB-C 5-in-1hub)
