On July 14, Apple suddenly launched the first official mobile power supply: MagSafe external battery. The mobile power supply, which costs 749 yuan, has many different settings from the existing products on the market. It can even be said that Apple is using the idea of smart products to do mobile power.
Specifications:
749 yuan, 11.13Wh capacity (equivalent to 2460mAh under 3.8V), Lightning interface;
Up to 9V 3A 27W input, up to 15W wireless output (when connected to the power supply), and 5W wireless output for independent operation;
The iPhone 12 series is universal. The width and rounded corner of the MagSafe external battery are close to the iPhone 12 mini, and the weight is not announced;
The charging head and cable are not included in the package.
MagSafe external battery has many special points. Apple is worthy of you
The independent wireless output is 5W. After the battery is connected to a 20W charging head, it can output 15W MagSafe. It is equivalent to the MagSafe charger function (the latter costs 329 yuan). If you cheat yourself, you will feel more comfortable;
IPhone can charge MagSafe external battery wirelessly. Everyone stands up, and the iPhone can finally be charged wirelessly in reverse (it is required that the iPhone's power exceeds 80% and is connected to the power supply, which is mainly used in the case of wired connection between CarPlay and the computer). The output power is unknown;
When charging the iPhone and MagSafe external batteries together, the MagSafe external battery will wait until the iPhone's power exceeds 80% before charging itself;
If the iPhone power exceeds 80%, when the MagSafe battery overheats, it will automatically stop charging, and automatically resume charging after cooling;
In iOS 14.7 or above systems, you can view the power of MagSafe external battery on the desktop plug-in ↑;
Unable to charge iPhone wirelessly. Because both the battery and the mobile phone are connected to the Lightning interface, there is no charging cable for dual ended Lightning (it is useful to use a dual ended Lightning cable to guide data);
The capacity of MagSafe external battery is only 11.13Wh/7.62V, which is about 2460mAh at 3.8V, less than 1/3 of the common 10000mAh mobile power supply (38.5Wh, 3.85V). The iPhone 12 mini with a capacity slightly greater than 8.57Wh/2227mAh battery, while the iPhone 12/12 Pro is 10.75Wh/2815mAh, and the iPhone 12 Pro Max is 14.13Wh/3687mAh.
Its capacity is not enough to enable iPhone 12 and above models to complete a 0-100% charge at a time, including the loss of step-down and wireless charging, which is one of the reasons why mainstream mobile power is starting at 10000mAh today.
Apple has not announced the weight. Since the capacity of lithium battery is proportional to its weight, it is expected that MagSafe external battery will be lighter than 5000mAh mobile power supply, which is generally 150g or less. After all, too heavy is not convenient to carry, and the magnetic suction is not reliable (if it is heavier than the mobile phone, the mobile phone is not attracted to the mobile power, but the mobile phone is attracted to the mobile power).
When MagSafe's external battery works independently, it only has an environmentally friendly 5W output. However, MagSafe can always be sucked on the mobile phone for charging. More importantly, heat control should be considered. Considering that the MagSafe charger costs 329 yuan, the "cost performance" of MagSafe external battery is relatively high
