Sony had a different charger model (with a different voltage down to tens of volts, or with a different connector) for nearly every single device released.
Want more than one power brick (one for the office and one for the home/vacation home)? Spend a lot of money for the convenience, or carry 2 kilos of chargers wherever you go.
Some devices eschewed power supplies altogether and used cradles. Lose the cradle and the device is unusable. Carry the cradle, and it becomes an extra 500g in your everyday carry.
If you were lucky, your device supported a barrel jack or another generic connector, but you had to carry around a universal power supply with adjustable voltage and polarity because they all used different configurations. Get something wrong, and your expensive device is fried.
I remember the early 2000s and the pre-USB charger era. I don't remember it fondly, because it was frankly stupid. Even the worst universal standard is better than no standard at all. And I say this having lived through the era of Micro USB dominance, an era that has killed the charging ports of many of my phones.
