Question 1

My external hard drive is a 4 tb . I want to use this to pulg my hard drive and my wireless headphones that use a usb Transmitter. Will this work ?

Accepted Answer

Please note that since the hub is not powered via an external adapter it draws all its power from the computer's USB port. Therefore the current cannot exceed 0.9 Amps among all the ports. To ensure a stable connection, we would suggest not using this hub with high power consumption devices such as large-capacity hard drives. For a stable connection, avoid connecting devices that exceed a total of 900 mA. Devices are usually rated as follows:
Mouse 100 mA
USB Flash Drive 100 mA
Camera 300 mA
Keyboard 500 mA
External Hard Drive 900 mA

Question 2

Can this be used with 2.0

Accepted Answer

Simple answer: yes. More detailed answer: If you plug this hub into a USB 2.0 port on your PC it will function just fine as a USB 2.0 hub (not USB 3.0). If you plug this into a USB 3.0 port on your PC you can plug both USB 3.0 and USB 2.0 devices in and they will work correctly (USB 3.0 devices will work as 3.0 devices at the higher USB 3.0 speed; USB 2.0 devices will work as 2.0 devices at the lower USB 2.0 speed). Considering the price, size, and quality of this hub, I'd recommend buying this over a USB 2.0 hub even if you only intend to use it with USB 2.0 ports and devices -- it's only a few dollars more.

Question 3

Does the cheap model that doesn't come with external power source have a USB plug for adding wall power?

Accepted Answer

For those who might be unaware, some USB devices require a powered USB hub. So it's not that this hub doesn't require external power, but that it doesn't offer it as an option and therefore supports fewer devices.

Question 4

Does it work well with apple charging cables, does it charge fast?

Accepted Answer

It charges my devices just fine. It's just not a fast charger. I can have my android watch, fitbit, and logitech gaming headset charging at the same time and they all charge just fine though.
