What it does
A thin, bus-powered hub that turns one USB-A port into four USB 3.0 ports for drives, mice and keyboards.
- Four USB 3.0 ports in a flat bar about 0.4 inch thick
- Plug and play with no driver or power adapter
- Built-in cable with a cable tie for tidy storage
- Sold in a 2 ft cable version and a shorter 0.75 ft version
- Works with flash drives, mice, keyboards and other low power devices
A cheap, simple way to add USB-A ports to a laptop or desktop for flash drives, keyboards, mice and the odd portable drive. It takes no power adapter, so it cannot charge devices and is limited to 900 mA shared across all four ports, which rules out several power-hungry devices at once.

Questions
Can the Anker 4-port USB 3.0 hub charge my phone?
No. Anker states this hub does not support charging. It is a data hub.
Does the Anker ultra slim hub need a power adapter?
No. It draws power from the computer's USB port. Anker recommends keeping total draw across all devices to 900 mA or less.
Does it work on a Mac?
Yes. Anker lists support for Mac OS X 10.6 to 10.12 or later, plus Windows and Linux.
Why does my wireless mouse lag when plugged into the hub?
Anker notes that 2.4 GHz wireless devices may not work well close to USB 3.0 devices. Moving the receiver to another port or away from the hub can help.
