Is there a way to slow down these high power chargers? Sometimes I want a fast charge but mostly I want slow to getting hot. I realize overnight charging phones are smart enough to do this but otherwise seems to be impossible without having two different chargers.

I still keep a few 5 watt chargers around and use them for overnight charging whenever possible. I reserve the use of high power chargers for the odd occasion when I need the speed.

Earlier quoted context omitted.

I bet their telemetry shows that a lot of people grab a quick charge while in the shower or the like, and that 10mins is a good amount of time for that. Or put another way, past ten mins it’s just as likely the phone will be plugged in for hours or overnight and the charge speed is irrelevant.

Also, it may be to avoid overheating the phone. Otherwise you might expect to see a GAN charger where the body is a heat sink.

That should be on the phone to increase its own resistance and slow down the power intake.

This is very cool, I might actually get one to charge my laptop.

That being said...

I can't be the only person who consciously avoids fast-charging my phone. My whole apartment is full of wireless charging pads intentionally plugged into weak chargers (wireless charging avoids putting wear on the USB port). 60 watts can't possibly be healthy for a battery small enough to fit into a phone.

This is why I'm glad my phone has a cooling fan that can be set to come on during fast charging https://i.imgur.com/05lhMJA.jpeg

The pictures in the article are very nice and well done but I could not stop noticing the dirty yellow cable they used in some shots…

Didn't see that, but they do tend to look that way after some real-world usage.

Yeah its just a shame – the photos look so professional and clean otherwise.

Hopefully Apple releases a UK version of this adapter soon. The design looks very similar to my beloved Apple UK 20W charger [1]. I’d buy a 40-60W version in a heartbeat! [1] https://www.amazon.co.uk/Apple-20W-USB-C-Power-Adapter/dp/B0...

Similar design is a Ugreen Nexode 45 watt charger[0]. Folding prongs, May be ever so slightly larger. I just purchased one for an upcoming trip. 0: https://www.amazon.co.uk/UGREEN-Foldable-Charger-Support-Com...

My Apple 20W UK charger measures 49 × 45 × 30 mm, making it much smaller than this Ugreen one (50 x 50 x 42 mm).

I'm guessing an Apple 40-60W UK version might come in somewhere in between in size?

There's also the Anker Nano 45W, at 49 × 49 × 34 mm: https://www.amazon.co.uk/dp/B0DPR2VYQF

How do you manage that with magsafe/qi 2 chargers if you want to benefit from the greater efficiency and magnetic alignment? They’re all USB-C, and you can’t trivially buy USB-C chargers that are good for only 5W.

Meanwhile me with a 100 W charger for my OnePlus 13...
