For devices I have a work laptop, work phone, personal laptop, personal phone, headphones, usually a couple other small devices, and a mobile battery. I usually only heavily use my work laptop and personal phone. For phones and smaller stuff, I can charge them from the laptop while the laptop charges overnight so I don't typically wish for a second charger. If your laptop has decent battery life, charging at less than max speed is no big deal (I have two 16 inch MacBook Pros).
Additionally, I've converted most of my old favourite micro-usb devices like mouses to usb-c. A search for "usb-c 4.7kohm 5v female" will give you some options for replacing micro-usb with usb-c, with hobbyist soldering skills.
For a beard trimmer, I got an Enchen boost usb-c model for $10 for travel. It works well and even has ceramic blades but I had to add 4.7k resistors to work with a c-c cable[1].
[1] Cheap devices often omit some 4.7k resistors that tell a usb-c charger to output 5V, so it outputs nothing. This is why some devices work only with usb a to c cables, as usb-a outputs 5V by default. If you can manage to add the resistors to the correct pins or replace the connector with one that has them built-in, you can fix this problem. The difficulty of doing this varies a lot by device.
