I'm impressed at the ignorance of some celebrating this as if a 5W charger was 'old'.
A 5W charger simply outputs 1A of current. a 10W gives 2A and you get the idea... V x I = P, good ol' basics.
Is not 'old', it's simply a different tool.
Small batteries like in headphones, watches, older phones, and many devices simply cannot take the 2A/10W fed into them, and the increased current ends up creating a lot of heat.
Plus if your device it's somehow damaged and there is a short, since the charger can deliver the current, it'll just give it, potentially extending the damage.
Some ppl already said it, fast charging kills your battery faster.
Higher currents will tend to kill a battery faster. Not for big devices obviously like laptops or iPads, but that's precisely my point: each device has its optimum charging current.
My previous phone was an iPhone 7+ and I had to change the batt because it kept on crashing due to the throttling that took place because the batt was so degraded and couldn't deliver enough power (nor get charged properly).
All because I was running gigs (events) like a maniac on 2A chargers as couldn't be without my phone too long, or needed to use it as a hotspot for internet.
I tend to charge my current phone (i13ProMax) with a 2A (10W) charger when I'm low and need quick juice. But ideally try to use a 1A charger so it might be slow, but I don't kill my batt in the process.
Got an iPad Pro and I use the original 3A charger (15W) -- but if I plug that into my iPhone, then yes... still awake, but at what cost? xD
A bit unrelated, but Raspberry Pi's are a bit hungry and need 5V@2.4A min, 3A to be safe and run extra stuff.
The NVidia Jetson family is quite power hungry and needs 3A min.
A toy car of my nephew had a step-down transformer on the USB plug itself, from 5V to 4.2V @ 0.5A, that's a 2W charger... appropriate for a tiny battery (charges full like in 10 minutes).
Each device with its own charger/PSU. Specially if there is no power delivery limitation/control or 'Smart charging' capabilities.
I'll miss them and will even try to get my hands on a couple more, as they are tiny and can come handy for certain low-power applications.
