Hardware USB hub power question...

[eldavo2090]

So I have this USB hub, and so far has been working well with some USB controllers and a GC adapter.
Yesterday it sometimes disconnected my controllers when playing Smash Ultimate, it did that 2 or 3 times then I unplugged the port for rumble and worked fine. So I looked around my house and found a AC adapter with multiple voltages and with a compatible connector, my question is: for a 7 port USB hub what would be the recommended voltage?

Check the info on the USB hub, wrong voltage will fry the usb hub.

All pc usb hubs without their own power supply are 5V only(if it just has a usb plug that plugs into pc). If it has it's own power input/adapter, a barrel plug for example, it MAY? be 12V. Is there a label on the hub at all?
if it has 2 usb plugs, one can be plugged into a cell phone charger, and the other to usb.

You need Amperage not voltage probably, so a 2A 5V supply should do it.

It has no label, but it has an adapter where I can plug an AC adapter. It's a cheap hub that I found in a Mexican flea market... But has worked pretty good so far!

I have a 7-port hub that came with a power adapter, it's rated at 5V - 4A.
