[Material evaluation] Apple MagSafe external battery evaluation: will magnetic suction be the development direction of mobile phone accessories?

portable source I believe you are not unfamiliar, especially for users who have used a mobile phone for two or three years, they will basically take a mobile power supply with them when they go out. Relatively speaking, the price of most mobile power sources on the market is basically within 200 yuan, which is also considered to be friendly to the people.

MagSafe external battery

However, there is an exception. On July 14, 2021, Apple released a "mobile power" with a price of 749 yuan, officially called MagSafe external battery. The high price and strange charging form also caused quite a stir at that time, and the online evaluation of this product was mixed. I have used this product for more than half a year, so today I would like to share with you my real experience of this product.

1. This is not really "mobile power"

First, let's talk about the definition of this product. We also mentioned that the official name of this product is MagSafe external battery. In combination with my own experience, it is not really a "mobile power supply" in the true sense, but more like the second backup battery of the iPhone, so we cannot use it as a "mobile power supply", The phone is only used when the power is off. Instead, the MagSafe external battery is magnetically attached to the back of the iPhone when you go out.

In fact, this positioning is somewhat similar to the "Smart Battery Case" launched by Apple for each generation of iPhone products. The difference is that thanks to the addition of the iPhone 12 series and subsequent models MagSafe, the MagSafe external battery is magnetically attached to the phone, which saves a lot of money for users who buy new iPhones every year.

2. The capacity of MagSafe external battery is not large

When talking about such products, battery capacity is naturally a core element. The magnetic suction surface of MagSafe external battery is printed with model: A2384, input: 5-9V3A, capacity: 1460mAh, energy: 11.13Wh, battery pack voltage: 7.62V. In combination with the official announcement that MagSafe external battery has a built-in double string lithium ion battery pack, which means that the total capacity of MagSafe external battery is about 2920mAh. Considering the loss caused by normal energy conversion, The MagSafe external battery is difficult to recharge the power of models other than mini.

3.113g is not suitable for daily carrying

In terms of weight, after our test, this MagSafe external battery weighs 113g, which is relatively light compared with the general mobile power supply. However, considering that the mobile power supply can hold a cable in the bag, and the MagSafe external battery can only be held in the hand all the time, this weight is not very friendly.

Take the iPhone 13 Pro I am using personally as an example. The bare machine weighs 203g. Even if I don't stick a film and wear a protective case, the weight of the MagSafe external battery is 316g. Unless I have mastered the "Kirin Arm", the MagSafe external battery is not suitable for daily carrying.

4. It is almost difficult to find substitutes of the same level in the market

Although we talked about some shortcomings of this product, it is still difficult to find a product that can surpass, or even replace, MagSafe's external battery. Here I also summarized several major pain points of the same type of "magnetic charging treasure" on the market at present: poor magnetic performance; No power display function; The wireless charging function needs to be activated manually; Large size, unable to fit perfectly with iPhone; Severe fever. These are precisely the advantages of MagSafe external battery.

However, for ordinary users, I still do not recommend that you buy MagSafe external batteries at the original price. If you really want to try it, you can look at the "Magnetic Power Bank" launched by a third party.

First of all, the price of most of the "magnetic charging treasure" on the market is about 100 yuan. Compared with the price of 749 yuan of MagSafe external battery, it is more user-friendly. In addition, although I have mentioned several pain points of the third party "magnetic charging bank", these pain points can be compensated with a budget of 600 yuan. Finally, for MagSafe external batteries such as "Huaqiang North 7-piece Set" and "Huaqiang North University Gift Bag", I hope you must stay away from them. In particular, such products with built-in batteries still have many potential safety hazards.

Don't buy the so-called "Huaqiang North products"

5. Will magnetic suction be the development direction of mobile phone accessories?

After talking about the products, I finally talked about Apple's MagSafe Magnet Ecology, a new technology released with the iPhone 12 series. In a nutshell, a circle of magnet is built in the back of the phone, which has reached the ability of magnetizing the product on the back of the iPhone.

This technology was originally designed to help the MagSafe charger (mobile version) accurately locate the wireless charging coil on the back of the iPhone. With the MagSafe magnet on the iPhone 12, 13 and 14, many friends have also developed a new way to play the magnet. Such as "magnetic card bag", "magnetic mobile phone bracket", "magnetic airbag" and even "magnetic cloud deck".

OPPO Find X3 supporting magnetic suction wireless charging

From my own experience, magnetic suction is definitely a "hard to use" function. More than that, at the OPPO Future Science and Technology Conference I attended earlier, I also saw that OPPO is also studying products that support the magnetic suction function. So for now, I am very optimistic about the future development direction of "magnetic suction".
