The website ChargerLAB today published a teardown of Apple's new 40W Dynamic Power Adapter with 60W Max, which has a key advantage over one of its other chargers.

Specifically, the teardown shows the new 40W to 60W charger is roughly the same size as Apple's 20W charger, despite its higher wattage for faster charging speeds. In other words, you are getting more power from a smaller charger, although the 40W to 60W model costs $39 in the U.S., while the 20W option costs $19.

To achieve this, the charger supports USB-C Power Delivery 3.2 with SPR AVS (Standard Power Range Adjustable Voltage Supply), according to ChargerLAB.

The teardown confirms the charger can approach its 60W limit, but this will only be in short bursts, due to the thermal limitations of its compact design.


In addition to the U.S., the 40W Dynamic Power Adapter with 60W Max is available to order in Canada, China, Japan, Mexico, Taiwan, and the Philippines. It appears to be the spiritual successor to Apple's discontinued 30W adapter, which is still included with the base-model 13-inch MacBook Air and the Apple Vision Pro for now.

iPhone 17, iPhone 17 Pro, and iPhone 17 Pro Max models can be charged up to 50% in 20 minutes with a compatible charger, including the 40W to 60W one.

Wait, so there are no other existing chargers that can do this, including ones with higher wattages? It requires this new power delivery spec?
The article does a poor job of explaining what this charger does and what makes it unique.

All chargers that support USB-PD can vary their power output according to what the device needs, up to a specific limit.

What this particular charger does it it allows the charger to go 20 watts over its charging limit to 60 watts if certain conditions are met (ie: it's not too hot), and it can only do it for a limited amount of time. It's sort of like the turbo mode on a CPU, it can boost to a higher clock speed for certain tasks but it usually can't sustain that maximum speed indefinitely.

So in effect with this version of the USB-PD standard you get the size of a 40 watt charger with the ability to boost to 60 watts for fast charging and similar scenarios.

I'll be interested to see how this compares to the Anker Nano II 715 that's rated a full 65w. If this new Apple charger is smaller and lighter I might make the jump.
 
I am guessing it’s kind of pointless to purchase this to use with any iPhone models that are older than the 17s? I already have a USB C charger that can output up to 60W but didn’t know if this one did something with the iOS to let it charge the phone faster…

This doesn't support PD 3.2, so The Anker will be circa 50% in 30 mins compared to 20 mins for this new charger.
