There was a time when USB power adapters were new, when mobile devices used various cables. If you go far enough back, every phone had a different wall wart and connector. The start answer is that we have a standard, so in most cases no dedicated adapter must be purchased.
Now virtually every device, with the exception of Iphone, uses USB C. Almost all phones can simply be plugged in using any USB plug, which are increasing available. No adapter is needed. While the PD standard is not absolutely uniform, even the MacBook has been able to run on any PD power supply.
I originally did think that it was useful to include a specialized adaptor for some devices, but I now believe the issues we had a few years ago with overcharging and over current have been solved in the device. Any charger that is not inherently defective appears to function well on any device that is not inherently defective. Devices like the Eero that use USB C but encourage use of a dedicated plug can assumed to be inherently defective.
The EU forcing standards for cell phones has been one of the best things that has happened to the industry. Of course Apple is still in the corner with its own Lightning standard, getting past the EU mandate with bundling an adapter, but before this went into effect, basically every phone had a completely different charging cable. Some phones used their own flat-edge connectors like Apple's 30 pin, some had round connectors, some used oddball USB variants, one phone I saw even used the audio jack with add
One suggests you get a copy of the OED, the z spelling is perfectly acceptable. In fact it is one of the things that anoys me about British spelling dictionaries they mark up correct spellings as wrong because it uses a z.

You can thank the European Union [europa.eu] for that standardization effort.
