MagSafe chargers that stick with magnets, a problem that isn't very safe. What are the benefits of wireless ...

MagSafe is not safe.

I didn't say this because I came up with a good phrase, but when I touched it, I felt that way. The common new function "MagSafe" of the iPhone 12 series is to put a magnet on the back of the main body to attach charging pads and accessories to each other. I was excited when it was announced.

The MagSafe charger is newly released to take advantage of this new feature. Unlike conventional wireless chargers, the power of magnets makes it possible to charge the sweet spot with a snap. Moreover, it realizes a maximum power supply of 15W, which is a high output for wireless charging.

Can it be charged wirelessly well, and how does the magnet snap? When I touched my heart with expectations, I could see the good points and bad points of this guy. It's wireless, but it's wired.

Reliable magnet power

Looks like this when connected to the iPhone 12 Pro. The MagSafe charger has a magnet on the outside that snaps onto the back of your iPhone. Judging from the response of the magnetic force, it seems that a magnet with the same radius is installed on the back of the iPhone. When you move around the sweet spot, you can feel the resistance as if the same poles were brought closer to each other.

This is about thin. Even if you play with your smartphone while charging, it will not get in the way as much as the Lightning terminal. You can change the direction of the charger by changing the direction of the charger.

It is a magnetic force that is worrisome, but it is quite powerful. As you can see, the charger floats and sticks together. At first, I held the iPhone with one hand, but with one hand, it was pulled by the charger and the iPhone tilted. So powerful.

Also, the magnetic force felt like iPhone 12 Pro> iPhone 12. It is unclear whether this difference is due to the difference in surface treatment or whether it is differentiated in terms of hardware. Does it make sense to differentiate?

It has a lot of resistance to swinging, and even if you lift or pendulum the iPhone together with the charger, this is the case. It came off when I pulled it with recoil, but it shouldn't be a problem unless I try to force it. Don't imitate good boys or gadget lovers!

If it is a MagSafe compatible case, you can charge it through the case. The case itself also has a magnet, so even if you bite the case, the magnetic force will not drop. It feels a little stronger.

What's more, the iPhone recognizes the mounting of the case itself with this case and mystery technology! Like the gif above, you'll see your own effects when you attach the case to your iPhone. Is this related to charging through the charger?

The advantages of using the MagSafe charger in real life are "almost no wireless charging (15W power supply)", "charging terminal does not get in the way (iPhone can be used while charging)", and "other gadgets are also wireless". Being able to charge "etc.

In particular, when playing games and distributing while charging, the handling has become overwhelmingly better than the conventional Lightning terminal charging style. Whether or not the power supply can be supplied at 15W depends on the work. Only the iPhone 12 series can benefit from the magnetic force, so those who are considering the iPhone 12 are wondering whether to buy it as a set.

The strong magnetic force becomes a ghost ...

Now let's talk about the negative aspects of MagSafe. The strong magnetic force can carry the entire iPhone if the cable is caught. A common problem with wired charging is safety. Not Safe.

Next, the bent terminals of the charger and cable are scary. Bending loads, such as the Lightning cable connected to your iPhone, can be applied to the base of the charger. As the magnetic force is strong, the force applied is also large. Wasn't the merit of wireless a liberation from this kind of thing?

Even if the cable is on top, it will bend like this. Why not lift the charger instead of the cable? You can still remove it, but you need a lot of power. Moreover, it is difficult to grasp because it is thin. Let's lift the iPhone obediently.

Also, Apple's claim is that it "sticks to the perfect position with magnetic force", but it's not as perfect as you might think. At first, I thought that if I removed the sweet spot, the resistance of the magnet would lead me to the correct position, but it wasn't. Adsorption to the sweet spot works only when it arrives near the correct position.

In other words, just because it's MagSafe doesn't mean it's OK to put it casually. If it sticks to the top or bottom of the back, you'll need to manually remove the charger and then reapply it near the sweet spot with the Apple logo.

If you think about it, MagSafe on the MacBook is a terminal, so there was no way to shift the position. Even if it bears the same MagSafe name, the parts other than the magnetic force seem to be quite different in terms of design and usability. Expecting the ease of use of MagSage, disappointment is inevitable ...

And this is the biggest point of overturning.

You need to use both hands to remove it from the charger. Since the magnetic force is strong, it can not be removed just by lifting the iPhone → Remove it with both hands → This is the same operation as the Lightning cable ...? I met the door of truth.

I think the solution is to fix the charger tightly. Or just hang the charger and charge it in the air ... After all, when using the MagSage charger alone, there is a high possibility that the advantage of the wireless charger, "quickly put it down and quickly collect it," cannot be realized. Too strong magnetic force grabs the iPhone as if it were wired.

How to master the romance of magnets

What a gadget for making wireless charging comfortable would be similar to a wired charging style. It's good until it's charged. Adsorption to sweet spots, high-speed power supply of 15W, support for other gadgets, etc. The problem is when removing it. If you come up with a smart solution, please share it ...!

Rather, what I'm looking forward to from MagSafe right now is the full range of MagSafe-compatible accessories. Currently, cases and wallets are appearing, but they should come out one after another from third parties. It seems that magnets have a romantic function and are worthwhile.

Research on how to use MagSafe will continue to progress. The response of the charger was not good, but the strength of the magnetic force was more than expected, and messing around with the smartphone while charging is really good. … Is there a good theory that this is no longer a wireless charger, but a wired charger that is easy to remove?

By the way, it just stuck to the iPhone 11 Pro. It looks like it will come off soon. It won't lead you to the sweet spot, but you can enjoy 12 feelings ...?
