Ecosystem and mutual compatibility have always been the skate of Apple's branded devices. Therefore, buying an iPhone, you could be sure that it can be charged by the power adapter for the iPad and vice versa. Of course, this is the smaller of the advantages of Apple's techniques, but very indicative, since recently it has been treated in Cupertino after the sleeves even to such little things as mutual compatibility of accessories. But if the use of different connectors in different devices can still be understood, the incompatibility of power supplies is, in my opinion, too.
Samsung and Microsoft will also remove the headphones from the smartphone box: in charge of charging?
Confusion with Apple power units began at the end of last year. The company has released several devices at once, which turned out to be unable to work with some of its branded adapters.
What charging is supported by Magsafe
The first such gadget was the magnetic charger Magsafe. Immediately after the release it turned out that it was able to charge the iPhone 12 on the power of 15 W only when using a 20-watt power adapter. But if you connect other memory to it, then power and, accordingly, charging speed will fall. This applies to both Apple's branded memory and third-party:
- Apple 30 W Power Supplies USB-C - 15 W Magsafe
- Apple 20 W Power Supplies USB-C - 15 W Magsafe
- Apple 18 W USB-C power supply - 13 W Magsafe
- Apple 96 W USB-C power supply - 10 W Magsafe
- Power supply Anker 30 W USB-C - 7.5-10 W Magsafe
- AUKEY 65 W USB-C power supply - 8-9 W Magsafe
- Google Pixel USB-C - 7.5-8 W Magsafe
- Power supply Galaxy Note 20 USB-C Ultra Charger - 6-7 W Magsafe
Apple told about the problems that Magsafe charging
It was then it turned out that the dual charging of Magsafe Duo also experiences compatibility issues. True, she has a little 20-watt memory, which is used with the original version of Magsafe. To squeeze from Magsafe DUO maximum, you will need to use power adapters from 27 W. That's just a 29-watt charger, which Apple supplied with MacBook 12 "and the first generations of MacBook Air Retina, is not suitable. But the 30-watt block is suitable. In general, some sur.
Why Apple Charger charges slowly
So what is the reason? It turns out that the incompatibility of different power adapters with different Apple devices influenced several factors at once. As John Gruber explained, the Daring Fireball journalist and the long-time researcher Apple, some of the company's branded charges, first, do not support the USB-C PD protocol, and, secondly, they do not support all power supply profiles.
USB-C PD is a Power Delivery protocol that provides fast charging.
Power supply profiles are options output power supply power supply unit for charging devices.
Here are the profiles of the 29-watt Apple power adapter:
- 14,5V x 2a = 29 W
- 5.2V x 2,4a = 12.48 W
So that he could pump Magsafe Duo, he needs a 9V x 3A profile = 27 W, but the 29-watt block does not support it, because it was released for a very long time, and during development this moment was not thought out. But 30-watt - supports. He generally has a spectrum of available power supply profiles noticeably wider and universal:
- 20V x 1,5A = 30 W
- 15V x 2a = 30 W
- 9V x 3A = 27 W
- 5V x 3A = 15 W
What is happening? A 20-watt power supply is used for conventional MAGSAFE, since it corresponds to the desired power supply profile, providing the necessary output power. Magsafe Duo, since it simultaneously charges two devices, the profile must be different, so the 20-watt adapter does not fit it, since it is physically not able to give 27 W. It seems everything is logical, but not very nice, given that users who own Magsafe and Magsafe Duo will have to buy different charging.
Buy Universal Baseus Charco
However, this problem is solved by buying a universal charger sufficient power and with PD support. For example, Baseus has an excellent 65 W solution, which supports all the necessary power profiles. Yes, such a memory is worthwhile - as many as 2 thousand rubles. But, buying it, you get, first, a universal adapter, which will suit all your devices, including a laptop, and, secondly, it will be more compact than Apple's branded charging.
Charging for homepod mini
By the way, there was also a third device from among half-compatible. This is homepod mini. Few know that the mini version of the smart apple column, unlike the original, allows you to connect and disconnect the cable and, accordingly, the power adapter. Included with HomePod Mini, a 20-watt power supply is supplied, but he didn't work from 18-watt at first, which is strange, because Apple devices usually support the charges of any power, they are simply charged from them slower.
Lightning cables from all iPhone are no longer suitable for old charms
Subsequently, Apple has released an update for homepod mini, and he began working with 18-watts memory, but in general the sediment remained. But then it was trite in software compatibility, and not in power profiles, which cannot be added postfactum. Why, in this case, it was impossible to implement the support of a less powerful power supply unit, especially since it is compatible with the column, it is strongly incomprehensible. Another thing is that last year the ecosystem in principle gave a failure, making incompatible a number of devices and accessories.
