17 R5, will the left USB-A port provide enough power?
Alienware 17 R5
I have an Alienware 17 R5 i9 laptop. I need to connect my coolpad and an external hard disk to the left USB-A port at the same time so I need to buy an external USB hub. The problem is that I am unsure if I need a powered external USB hub so it uses a charger or an unpowered external USB hub so it doesn't use a charger?
The external hard disks that I am currently using are Transcend StoreJet 25H3 4TB and WD MyPassport Ultra 2TB. I am unsure how much voltage they require. The coolpad requires input 5V 1.5A.
If I want to connect both external hard disks at the same time to the external USB hub then I definitely need to use a powered external USB hub. If I want to connect only 1 external hard disk and the coolpad to the external USB hub then will an unpowered external USB hub be able to support both devices or it can't?
Later on in the future I am considering buying a 3.5 inch nas disk and I put it in a 3.5 inch case which uses a charger. If I connect the 3.5 inch case and the coolpad at the same time to the external USB hub then will an unpowered external USB hub be able to support both devices? It should be able to support them because the 3.5 inch case is getting power from the charger.
