Basically it gives you the necessary ports for your Macbook 12", although keep in mind that it cannot use the USB C as an charger passthrough

I can't recommend this. I have the MBP 15" 2017. Tried 2 USB headsets, one works and one doesn't. Also, One of my USB3 drives works OK and one doesn't. To me, it looks like it is not USB compliant with regards to power output? Not sure, but don't have time to investigate further... by the way, the Apple USB-C Digital AV Multiport Adapter and the standard Apple USB-C to USB Adapters both work fine with all 4 of these devices, no issues.

This is being used on a Macbook. I bought this thinking I could keep my power cord connected thru one USB-C and use the other USB-C to add an external item. The regular USB's work fine but the USB-C ports DO NOT work. Neither USB-C port will give power to my computer, neither usb-c port will recognize my usb-c SD card reader, and only one will give power to (but not allow me to access) my external hard drive. The card reader and external drive have no issues when connected directly to the usb-c drive on the computer. DO NOT WASTE your $$$$.

Thanks to all you reviewers who obviously bought this hub for the same reason I was ABOUT to buy one ... namely to keep my Macbook charging while simultaneously using USB-A and USB-C peripherals like storage or Ethernet. To Belkin, I admit the your video and description *is* accurate, but you really aught to spell out that this hub will NOT answer the need that so many of us apparently have! To all you posters; sorry you wasted your money on this device but thank you for your posts so others like me don't follow in your footsteps.

The hub does what the description states... allows you to use multiple USB A type and C type devices with an existing USB C type port. It does not have passthorugh charging, and will therefore not charge your latptop / macbook (nor does it state anywhere in the product description that it will). Based on the reviews I am seeing, people did not fully read the product description... As a simple USB hub allowing for USB 3.0 transfer speeds it works great. My portable Type C drives function as they should with this hub, and it can charge my Type C enabled smartphone. The only negative, is that it should come with a power adapter to allow for more current use across the USB ports, to support faster charging and power of larger / more power hunger USB devices such as full size 3.5in External Hard Drives.
