USB Hubs for iOS real device farms

Support
1

Hello everybody! Thanks for taking the time to read!

Ive bought and returned 7 powered USB hubs on Amazon now. I finally found one that supports my 5 iphone 8’s but within 36 hours the USB gets disconnected by the mac due to excessive power draw. Note: This has a 120W power adapter. Iphone 8’s run to 12W but mine are fully charged doing nothing and have brightness at zero.

Im really hoping someone has some insights or ideas to help resolve the problem because everything works fine when its plugged in again. I am looking to increase my testing capacity but I just cant seem to figure this out. Maybe the answer is a different hub…What are you using on your 5-10 phone farms? Or maybe its a usb switch or some sort to schedule an unplug of some sort?

Thank you all so much in advance!

Check for example 16 Port USB 3.2 Gen 1 Rack Mount Hub w/Surge Protection and DIN Rail

In general, only look for industrial solutions - they have better reliability characteristics and wider acceptable temperature ranges

Also consider a proper cooling solution in the lab as this equipment produces lots of heat.

Just bought one. Will report back. Thanks. I think it might be worthwhile for there to be guide somewhere on here about this topic. Im sure it would save Amazon probably $50k in returns lmfao

I use InLine® USB 3.2 Gen.1 7 Port Hub Aluminium Case with 2.5A Power Supply black |Hubs | Input / Output | Products | inline-info.com with iPhone11 and Nokias Android phones.
Now use 4 hubs with 25 phones.
