Quick Installation Guide

Q: is this power with a 120V adapter.

A: Yes, there is charging port on this mini-hub and it does require you to plug into a 120v outlet.

Q: Is there a USB Hub that allows you to charge the iPad while you use the devices that are needed to complete your tasks that the iPad is used for?

A: I can plug this one into an outlet with the transformer provided and can charge my IPad, IPhone etc.

Q: Can this hub work as USB extender for small laptop accessories when not plugged into wall power? Or only with the juice? Thanks

A: The power source is not necessary for full functionality, only for heavy wattage devices such as external hard drives. It is bus-powered and therefore will work once connected to the computer.

Q: Excuse me, what is the cable measure?

A: The cable length is just under 2 feet (23.6 in or 60 cm).

Q: Is this USB Hub compatible with both Windows 10 and Windows 8.1

A: Yes, this device will be able to work on both Windows 10 and Windows 8.1.

Q: Will this work on a Nintendo switch?

A: Yes, it will work with Nintendo Switch.

Q: Would it work to plug in 2 of these together to basically make a 7 port hub without having to plug into an outlet as well?

A: I have not tried it, but I know you would need 2 A/C sockets to plug each one in. Could you plug each one into a separate USB port on the computer? You would lose two and gain 6.

Q: How long is the cable?

A: short-maybe 3ms

Great USB Hub
Compact and great USB hub for anyone needing additional ports. External power ensures no loss of connections. Transferring data between multiple sources now a snap. Mounted next to my computer with nylon straps to keep unit from sliding around.

Excellent small powered hub
I own four of these powered hubs (three in use, one spare). The housing is made of aluminum, and is nicely crafted. They work flawlessly on my two apple computers. I have the iMacs on short platforms to elevate each iMac slightly above desk level; one USB hub is mounted to each platform with heavy duty double stick tape. This makes it far easier for me to insert/remove frequently used USB flash drives, USB chargers, etc. at the front of the computer (versus reaching around to the rear of the computer). The USB hubs are low profile in thickness, and have three USB ports to the front, one port on one end, and the power port at the opposite end where the supplied wall wart power unit is connected. Great USB hub.

Perfect for external fan pads!
Works perfect for my setup, I really needed an externally powered usb type 3 so I could plug in my laptop fan pad without drawing juice from my laptops power supply. I have my external hardrive connected with usb 3.0 and my keyboard/numpad hooked up as well hooked up as well. The sleek profile was also far superior than many others on the market, you could tell they did not sacrifice function for form when they designed it.
