I have some USB-C MagSafe adaptors, but
- they're not designed for high power (needed for a laptop)
- they won't work for data (so you still need a dock)
- they have to be unplugged when you need to use the port for something else (or you lose one port)
- I'm a bit wary of plugging them into something expensive (I've seen some odd failures when using them that could be power related)
A proper MagSafe power adaptor would be nice. I'd personally rather have separate power and then 3-4 USBs (with a majority of As! 95% of my devices need A, and I've stopped plugging the rest in to the laptop).
Interesting story: I connected an AWatch charge cable to a hire car via USB C (hub plus A cable). The cable was faulty and caused the car's infotainment system to fail repeatedly, then shutdown completely (I still had basic driving capability, but I lost all navigation, fuel range etc). Obviously, the charger was shorting out internally (bare wires). I'd assumed the power supply would be protected, of course, or the hub would detect the overload! Luckily, I didn't cause a fire, and all started working again when I removed the cable. It makes me cautious with power
