Apple releases 70W power adapter for 15-inch MacBook Air

Apple unveils new 70W USB-C charger

On June 6, 2023, Apple held the WWDC23 Developers Conference and released hardware such as the MacBook Air 15". At the same time, Apple also launched a 70W USB-C PD charger for the MacBook Air 15" as an accessory purchased at its own expense.

Information about Apple's 70W USB-C charger from the China Quality Certification Center database: Apple 70W USB-C Charger Model A2743. Input specification 100-240V ~ 50-60Hz 1.8A Output specification 5V3A / 9V3A / 15V3A / 20.6V3.4A, PPS voltage subset not included.

At present, the Apple 70W USB-C charger has been sold on the official website of Apple China, priced at 399 yuan.

Why upgrade to a 70W charger?

The test found that the peak charging speed of the MacBook Air 13" (2022 M2) model has exceeded 70W+, and the standard 35W charger is difficult to provide it?fast charging.?

Record 0%-100% charging situation, MacBook Air also exceeds the upper limit of 67W Apple charger, peak power and continuous power exceed the upper limit of 67W charger, so it is reasonable for Apple to update the 70W charger for better Suitable for thin and light portable computers like MacBook Air M2.

70W charger shrinks in size?

After scaling the newly launched 70 this time, it can be seen that the newly launched 70W charger is smaller than the 67W charger, between the 67W charger and the 30W charger. It is speculated that the size of the 70W charger is about 64 *64*28.6mm, volume 117cm3, power density about 0.6W/cm3. Of course, the above are all speculations.

Let’s take a look at the data of other Apple chargers. The power density of the 30W charger is 0.39W/cm3, the power density of the 67W charger is 0.43W/cm3, the power density of the 96W charger is 0.52W/cm3, and the power density of the 140W charger is 0.67 W/cm3. It can be seen that the power density of the new 70W charger is close to 140W, which is a big leap in the middle power end.

GaN gallium nitride charging head has higher power density?

(Gallium nitride is an inorganic substance with the chemical formula GaN, which is a compound of nitrogen and gallium. It is a semiconductor with a direct energy gap.)

When it comes to charging density, gallium nitride GaN comes to mind. Gallium Nitride charger is the smallest and most powerful type of charging. It can be really small and powerful.

On the left is the latest 70W power head of Macbook Pro, and on the right are two Yogee gallium nitride charging heads, 100W and 65W respectively,

Apple 70W 64*64*28.6mm, volume 113cm3, power density about 0.6W/cm3

Yogee 100W 71*46.6*25.3mm, volume 84cm3, power density about 1.2W/cm3

Yogee 65W 61.7*36*24mm, volume 53cm3, power density is also about 1.2W/cm3

It can be seen that the power density value of the Yogee charging head is quite beautiful, and the small body has big energy!

Yogee's new product GaN adapter

The output power range of Yogee GaN charging head is 100W: 5V3A, 9V3A, 12V3A, 15V3A, 20V5A and also includes PPS: 3.3-21V5A. 65W: 5V3A, 9V3A, 12V3A, 15V3A, 20V3.25A. Compared with Apple's 70W power range: 5V3A / 9V3A / 15V3A / 20.6V3.4A, these three charging heads have a minimum output power of 15W, so they can be used for both computers and mobile phones.

In addition, Yogee's gallium nitride charging head series output power not only has 65W and 100W, but also has 35W, 45W smaller chargers. At the same time, in addition to the single Type-C port output, there are also different output port combinations to choose from, supporting single charging and multiple charging. There are a variety of dopamine colors to choose from, and the price is very affordable!

With the continuous development of science and technology, the pursuit of faster, stronger and more convenient charging products is endless, just like the development of computer size and computing power 30 years ago. Smaller size and higher power in the charging field Accommodating and more convenient charging methods, these are all positive to our life. Nowadays, people's life is inseparable from electronic devices, so it is very necessary to use an easy-to-use and convenient charging product! Let's look forward to more and more good new products and new technologies in the future.
