As Apple’s official partner brand, Belkin’s new products have always kept up with Apple’s pace.
It’s the same thing after apple launched their MagSafe charger.
The teardown product we bring to you today is the cheapest one in Belkin’s magnetic wireless charger stand.
The official price is $29.99.
Let’s see what it looks like.
The box is not small, and there is some information on it, Let’s see.
In addition to the brand logo and product picture, the compatible device models are marked here.
Only the iPhone12 series are supported at this moment.
And the same models are printed on the side of the box.
Here are some product features on the back, such as wirelessly charges up to 7.5W,
charge in landscape or portrait mode, etc.
Then, let’s open the box.
Except for the product, there is also a thick stack of manuals, and the power supply is not included.
The product’s shell adopts plastic with simple design.
The backside comes with a USB-C cable, which is very long, up to 2 meters.
And it’s also very thick and strong, pretty nice.
And the maximum power of 7.5W is compatible with any PD charger.
The bottom is covered with a rubber pad, which is stable when placed on the desktop.
Take a closer look at the specification here.
Made in Vietnam.
Model is WIB003 and the input supports 5V2A, 9V2A, 12V1.5A.
Its output is 7.5W, and the product has passed CE, EAC, KC, NOM, NYCE and other certifications.
Put the iPhone 12 on it, and it can be attached to the charging pad.
Using ChargerLAB POWER-Z KM001C to test the output power.
It’s about 7.7W.
After the phone is attached to it, the phone can be rotated freely.
Landscape or portrait mode is gonna be OK.
It’s very convenient to reply messages when watching TV.
Next, we gonna tear it down.
Start from the bottom rubber pad.
Tear it off.
There is an iron plate inside with six screws for fixing.
After taking it apart, nothing was found inside.
It seems that all the components are placed in the charging module.
Take apart the shell of the charging board.
There is a magnetic ring composed of 18 small magnets and a wireless charging coil inside.
There is a thermistor in the middle, which is used for detecting the temperature.
Turn it back.
The other side is the PCB, where all the components are placed.
Let’s see what these are.
The controller of the USB-C port comes from Hynetek HUSB238, used for control of input voltage.
This is a USB PD power chip, which has passed USB-IF and PD3.0 certification.
Its rated power can be up to 100W and withstand voltage is 30V.
But the power consumption is very low.
Here is the step-down converter that comes from MPS MP2229, with built-in MOS tube and fewer components.
The function of the step-down circuit is to adjust the corresponding voltage according
to the demand of the wireless charger.
This one can support Apple’s wireless charging of fixed-frequency and voltage-regulated.
Here is an alloy inductor.
The control chip of wireless charging transmitter comes from NuVolta NU1509,
which integrated ARM-M0 core and high-precision FOD algorithm.
It also has built-in fast charging protocol and supports comprehensive protection.
It can be equipped with NuVolta NU1009A, which integrated full-bridge MOS tube in power stage,
used for wireless charging.
It also has built-in switching regulator and LDO to power the master control IC and complete protection function.
This is a special thin film capacitor from Kyet, used for wireless charging.
Its specification is 0.4 μF, 100 V.
The thermistor solder joints are fixed in here by injection molding.
In this case, it won’t be easy to fall off.
There are two LED indicators on edge to show different colors.
The wireless charging coil is wound with Litz wire, which can effectively reduce high-frequency loss.
So that’s all for the teardown of this Belkin magnetic wireless charger stand.
It has a very simple design.
And there is just an iron plate at the bottom for stable support.
It can support up to 7.5W wireless charging and very suitable for home and office.
