Compatibility - Charger provided with the MacBook Pro 13" M3 chip

Thanks for your comments. It might be worthwhile reading my post again. Firstly, the new MagSafe Charger for the iPhone needs to be plugged into USB C charger. Now the new MacBook comes with a USB C charger. The question is, does the USB C charger provided with the new MacBook Pro provide the optimal charging protocol to use with the new MagSafe charger. This is a worthwhile question since it is useful to be able to use the USB C charger for different devices; negating the need to buy another charger. That would also be good for the planet and Apples environmental claims.

Comment:

1) Previous versions of Apple's 61W USB‑C Power Adapter do not have the required protocol as the new protocol were not developed when the original 61W USB-C Power adapter was related a number of years ago.

2) Apple has omitted the technical information of the charging protocols provided by the one they supply with the new silicon MacBook Pro on their website. Hence the important thoughts and questions.

Important thoughts and questions:

So, in the interest of the environment and integration of Apple products, the question remains: -

Does the charger provided with the new silicon MacBook Pro 13" (M3 chip) produce the optimal charging protocol ("9V/2.22A or 9V/2.56A and higher") required for the new MagSafe Charger?

Notes from webpage:

"Like we said, Apple uses 9V and 2.2A for its MagSafe Charger to get to 20W. You can only get this combination in USB PD 3.0 20W or higher wattage adapters — and Apple is not alone in providing that combination. A higher wattage alone won't work."

"When the MagSafe Charger negotiates for power it specifically looks for the 9V x 2.22A supply, which is only present in 20W PD 3.0 adapters — and only some with a greater power potential, given that it specifically needs that 9V x 2.22A supply. This is why it defaults to the 5V x 2A supply when using the 18W adapter, and will do the same with most — but not all — existing 60W USB-C power adapters."

"If you purchase a MagSafe Charger, be aware of the power adapter you use with it. Purchasing the Apple 20W adapter with the demanded specs for the full 15W charging from quality manufacturers will get you the desired results. Be sure to follow Apple's recommendations though, as 20W with USB PD 3.0 is the minimum in order to charge with MagSafe at full efficiency."

"any USB-PD 3.0 one with equivalent specs will do to get that faster charging speed, and a lesser one, won't.

USB PD is a specification for handling higher power on USB and allows a range of devices to charge quickly over a USB connection. It facilitates negotiation between two devices so they can determine how much power can be pulled from the charger. Power Delivery offers multiple power profiles from 5V to 20V, including a crucial 2.22 amp power profile."

Hi Halliday, I very much appreciate your comment..

Point of clarification:

You state that it fulfils the specification. This is incorrect. You have formed an inference.

Apple has not provided the specifications of the charger provided with the new silicon MacBook Pro. Apple could simply detail the specs and then it would be sorted.

Important thoughts and questions:

Apple is the biggest company in the world.

Why so secretive on this?

They could simply provide the specifications?

We don't need to be wasting our time and energy trying to sort this out because Apple has deliberately omitted this rather basic and very useful information.

Apple's has caused such questions to be asked that otherwise would be entirely unnecessary.

The question remains unanswered.
