I tend to shy away from Kickstarters, purely because there is no guarantee that you’ll get the goods after you fund them. But this one might be worth a look.
The DoBox is an all-in-one device, but it does a lot. Here’s a picture of what i suspect is their latest prototype:

It gives you an ethernet jack, 2 USB ports, HDMI, microUSB (for charging). You can use those ports to move data to/from your iOS devices and to charge your iOS devices. Lay your Apple Watch on top of the box to charge it without a cable (direct induction).
According to the video, you can use the USB port to attach a mouse and keyboard, use them on your iOS device. I’d love to see that firsthand. Sounds like a perfect travel device.
Lots of possibilities here. Jump to the KickStarter page and watch the video to get a sense of the DoBox in action. I’ll be getting one, will let you know how it works out.
I don’t know, sounds risky and seems to be claiming to do a lot more than what’s possible with a price tag of $149.
Hubs like this are increasingly commonplace.
Had I a need for this, I’d expect Other World Computing to have already made something like it.
With a delivery date of May 2017 (and these projects tend to miss ship dates by months if not years), I have a feeling that it will provide utility that will already be available from other devices.
I like their little dig at Apple on the page and they are spot on.
