Hello everyone. Welcome back to ChargerLAB.
In July, we tore down the apple official battery pack.
If you haven't seen it, you can click the corner to check it out.
Today, we find a very special "fake" MagSafe battery pack.
Let's see what's the difference between this one and the official version.
The packaging is almost the same as Apple's style.
We can see the product name, Apple logo,
MagSafe mark are all the same.
The front side is the product.
As for the back and two sides, I have to say the design is almost the same.
But compare with the genuine product. We can see this one is whiter
And the fake one is slightly darker.
And here is the back side.
Open the box.
It contains the product and the instruction manual.
Product name is Magnet wireless battery pack.
Then, let's see the product.
Em, I have to admit it really looks pretty good.
The outer shell is white, Apple logo is in the middle, and it also adopts rounded corners.
The contact part is gray. The magnetic ring is white.
Compared with Apple's battery pack,
Well, it's pretty hard to distinguish the fake from the back if we do not know in advance.
But for the contact side, the fake one is obviously darker than the genuine one.
And the surface touches worse than the genuine one.
You can feel a layer of oil, and it might be sticky after long time of use.
And it's also easier to leave the scratches.
You can even scrape off the surface coating directly with your nails.
Then, we can see the metal ring of Lightning port is very rough compared with genuine one.
And that's all for the appearance.
Then, its length is about 96mm (3.78 inches).
Width is about 64mm (2.52 inches). And thickness is about 12mm (0.47 inches).
And the weight is about 104g (3.67 oz). The genuine one
is about 114g (4.02 oz). The difference is about 10g (0.35 oz).
Try to charge iPhone 12 mini. Yep, it can trigger the pop-up animation
and "ding" sound. But it cannot be
successfully charged every single time. And it cannot display the battery level.
After many tests, we found it just shows up the battery level
at the beginning of charging. And disappeared later on.
But the genuine product will always display the battery level.
Try to charge this fake product with Apple 30W charger.
Power is about 6.5W.
Even when charging two devices at the same time, the power is the same.
The fake product cannot be fixed on the phone tightly.
But the genuine product can be attracted more tightly, and it is not easy to loosen.
Ok, that's the introduction of this fake MagSafe battery pack.
Let's see what's the difference inside.
Remove the front cover firstly. It just uses double-sided tape to fix it.
That's crazy.
The magnets and coils are attached to the plastic shell.
And the plastic shell is fixed by four screws.
Remove the screws and separate the coil.
Well, there is another wire in here. The other end is soldered on the PCB.
It should be used as a sensitive switch. It can activate the battery pack to turn
on wireless charging when the phone is attached to it.
Continue to remove the PCB of master control chip.
And separate the shell and battery.
The inside of this fake product looks very crude.
And let’s take a look at the battery, which is the 5000mAh lithium polymer battery.
It seems to have larger capacity compared to genuine product.
Rated voltage is 3.85V.
Then, Let's see the PCB of master control chip.
The All-in-one protection chip, which comes from Xysemi, is in the right corner.
And here is the master control chip, which is Injoinic IP5306.
It integrates boost converter, charging management, battery level indicator.
Only one inductor is needed to buck and boost.
This red one is the CBB resonant capacitor. From KYET.
And two MOSFETs are below, used to drive coil.
There are two single-chip microcomputers on the back.
This one is used for wireless charging control. And the other one is used for sensing and control.
Here is the protocol chip for Lightning port.
By the way, here are two solder joints reserved for thermistors.
Well, that would be the teardown for this "fake" MagSafe battery pack.
Compared with Apple MagSafe battery pack.
I have to say, $99 might not be expensive. Because we can almost say,
this "fake" battery pack is electronic waste. And safety should always be our bottom line.
