USB-C splitter for tethered photography

I am a professional photographer using Capture One for iPad and Fuji cameras.

On long shooting days the battery dies on the iPad before the shoot is over.

I need to connect an external battery to the iPad while at the same time staying connected to my camera via USB-C cable. I guess I need some sort of splitter? Not sure if a standard usb-c splitter would carry data and a charge simultaneously.

Shooting wireless is not an option. Too slow.

iPad Air 2, iPadOS 15

Thanks for the reply, Rick! So basically you just use a USB hub, right? How is the configuration of the setup? You have your tether cable from your camera + a power source connected to the USB hub & then you connect the USB-C cable of the hub to the iPad?


Not just "any" USB hub.


The USB-C hub must support USB-C pass-though power - to which you must connect a USB-C Power Adapter that itself supports USB PD (Power Delivery) via the power port.


The hub will have a USB-C host port that is connected to the iPad - this connection often being provisioned using a captive USB-C pigtail connection. Other USB devices are connected to the remaining USB Type A and USB-C ports of the hub.

You are very welcome.


While there are many suitable USB-C hubs available for iPad, when choosing, always check that the specifications explicitly list compatibility with your iPad Pro.


The suggested Kingston Nucleum hub is:

a) known to be fully supported by iPadOS.

b) is reliable.

c) is readily available in many countries.

Assuming your iPad has a USB-C port, you might consider a compatible USB-C hub that incorporates a USB PD pass-through input with which to connect your USB-C Power Adapter or USB-C Power Bank.


Perhaps consider Kingston, Anker, Hyperdrive and Satechi - although there are many others from which to choose. A Google Search for USB-C Hubs compatible with iPad will find a number of articles and recommendations. 


Speaking of personal experience, the Kingston Nucleum has proven itself to be particularly flexible for connection of high power USB storage devices - featuring twin USB3.1 Type-A, downstream USB-C and SD/microSD card slots, HDMI, plus a power pass-through USB-C port that can accept +45W from a suitable USB power source.
