This device does not require any power. It only requires power though the USB-C Power Delivery port when more than one high-powered device are simultaneously connected to the hub. The USB-C Power Delivery port chargers the laptop.

Two or more high-powered devices such as an external hard drives, iPhones, iPads, tablets, and other devices connected to the hub WITHOUT the USB-C Power Delivery port plugged is the reason.
High-powered devices require more power to make them run. You must connect a USB-C power cable from a wall power adapter to the USB-C Power Delivery port.

No it does not, this is for a safety precaution. SAFETY IS OUR #1 PRIORITY. It charges your Macbook Pro at a quick rate depending on the number and type of devices connected to the hub.
If Power Adapter is 87W, the MacBook Pro will get 60W from charger and the hub will get 11W from MacBook Pro, which results that the MacBook Pro get 49W.

Yes, but if high-powered device(s) are connected, the USB-C cable must be plugged into the USB-C port to provide power to those devices.

Yes. Use the USB C Power Delivery port on the hub.

No. You can not charge a device through the USB-C charge port. It only provides power TO THE HUB AND LAPTOP. Thus calling it "Power Delivery" to the hub and laptop.

No. The USB-C port only provides power to the Hub and to charge the laptop.

0.9A (0.9amp) or 900Mah

It actually is charging. You may see a the battery icon "Not Charging" but because of the power requirement for an iPad, it doesn't recognize the power going from the hub. Charge it for 1 hour you will see your big green battery icon getting filled and percentage higher than before. ​
Note: The Hub's USB 3.0 ports outputs 900 Mah (0.9amps). Because of the sheer compact size of the hub, the USB 3.0 ports will not output at times a full 0.9AMP. Some devices such as an iPad will charge noticeably slower, since it has a big battery. Since it is not directly connected to a power source such as a wall outlet, it will charger slower. ​
Note 2: Fast charging on IPADs happen from 20% to 80%, thus from 80% to 100% will be charged regular. Our hub does not have a fast charge since fast charge requires a 29W power adapter which is much higher than the 12W power adapter that came with your iPAD.

Both SD and Micro SD card size can read and write is 2TB.


Most laptops. Yet the charge function will depend on the laptop and power adapter. As we produce these hubs, there will be a few with compatibility issues.


Yes it works with both Macbook Pro touch bar and non-touchbar.

Yes. Please use the top USB-C port (indicated by the lightning sign) since the secondary USB-C port is just for data.

No. It draws power from the Macbook Pro.

THE SECONDARY USB-C PORT IS DATA TRANSFER ONLY. It will not charge your Macbook Pro. It will not charge your devices. It will not output video. Please use the top USB-C TB3 compatible port for those functions.


Both SD and Micro SD card size can read and write up to 2TB.

You can run ONE monitor at up to 5K@60Hz or you can run TWO monitors up to 4K@60Hz (a separate adapter will need to be plugged in with 2 video-out ports).

No. ONLY FOR for the new Macbook Pro with USB-C ports because of the 2 plug design.

HDMI Issues

Different Video Cables / HDMI Connection can cause issues. Keep in mind different types of video cables. We can confirm that our Type-C Adapters are only compatible with the HDMI to HDMI connection with a 1.4 or higher HDMI cable. DVI, VGA, and other additional video connections require a different adapter and will not work with our CharJenPro USB C Hub Adapters.

Most of our Type-C adapters do not work with PC computers. The HDMI feature may be supported if your laptop supports DisplayPort over USB-C with Alternative Mode

Flaky connection can be caused by the connection or the HDMI cable. Also, please try to adjust the on your computer settings to ‘never’. On a Mac: Please go to System Preferences > then select Energy Saver. https://support.apple.com/en-us/HT202824 By adjusting the "Computer Sleep" to never, it should resolve the flakiness in your HDMI connection. The Display Sleep shouldn't affect the Hub in any way.
