My wife and I recently went on a 7 week holiday around Europe. Although we each took a massive backpack, we wanted to travel fairly lightly. I took a single universal power brick. This little unit was all I needed to charge my various gadgets.
It has a hefty USB-C PD (Power Delivery) port for rapid charging of my phone and laptop. Two other USB-C ports for my other gadgets. And a couple of legacy USB-A ports which were redundant. The pass through was useful for using the same socket as the hotel's TV / lamp / coffee maker.
Wherever we were in the world, I was 100% confident that I would be able to buy a replacement charger if I needed it. USB-C cables are everywhere too. What are the chances that I could find the exact charger needed for a GameBoy Colour? Or the puck for last year's Pixel watch? Or the weird barrel jack for an HP laptop?

Laptop A Chuwi MiniBook. Small, light, decent battery.
eReader A no-name eInk device. I read a lot on holiday.
Watch A cheap but capable smartwatch. No magnetic charging dongle - just shove the cable into the body.
Toothbrush Again, a cheap and unbranded device. And, again, no charging dock - the bottom has a protected USB socket.
