That was the stated purpose for starting this thread! I ended up with the device I linked in my initial post. I've taken it on several trips already, and it's been super convenient. It's so nice to keep all the wall warts there they are (usually tucked behind night stands), and streamline my go bag. I do still have a bunch of cables I need to bring, but this device and a half dozen USB cables takes far less space than those cables and a half dozen wall warts. I was also able to ditch a power strip I used to carry, and I'm able to charge more devices at once than I used to.

I used to just bring a few chargers. One would charge my phone at night, and when I left a hotel room for the day I'd plug that charger into my tablet to have it ready for the evening. Now I can charge every device I own.

I'm very interested in using USB C to charge my XPS 13. So far, though, I haven't been able to charge it. The charger that came with my Nexus 5X can't do it, but that doesn't surprise me. I just don't know which of the chargers out there are capable, though, and that's yet another annoyance of USB C.
