Hi, guys. Welcome back to today's video.
Not long ago, we posted the teardown video of mophie wireless charger, you can click the corner to check that.
And today, we're going to take apart another product from mophie -
the 45W powerstation pro power bank.
The power bank adopts a woolen design and feels quite good.
The sticker printed with specs info is on the bottom.
Model is PS-PRO-45W-20K-A.
It can support input up to 20V2.25A, which is 45W.
The USB-C1 and C2 can provide up to 45W output, respectively.
And when using two ports at the same time, the power can be divided into 25W and 20W.
The rated capacity is 10400mAh.
And the manufacturer is zagg.
These two USB-C ports are also marked with power info in detail.
And the one on the left is the input port.
The mophie logo and power button are on this side.
There are four LED indicators to show the remaining power.
The size of this power bank is about 197 x 68 x 23mm (7.76 x 2.68 x 0.91 inches).
And the weight is about 397g (14 oz).
Connect it to the ChargerLAB POWER-Z KM002C.
It shows the USB-C1 supports PD3.0, Apple 2.4A and Samsung 5V2A protocols.
And it also supports four fixed PDOs of 5V3A, 9V3A, 15V3A, and 20V2.25A.
The supported protocols and PDOs of USB-C2 are just like USB-C1, but 20V2.25A is missing.
After the brief introduction, let's take it apart and check out the internal components.
Firstly, tear off the woolen material.
Then, remove all the fixing screws below it.
Open the case, we can see six 18650 batteries and the PCBA module.
And they are connected by these two wires.
The battery cell voltage sampling wires are fixed with heat-resistant tape.
And the nickel sheets at the end are insulated with barley papers.
This thermistor is also fixed by heat-resistant tape.
Remove the fixing screws and take them out.
And this is the connector for those sampling wires.
This foam is used to prevent the indicators from leaking light.
The high-capacity lithium battery is from CHAM and supports 1.5C discharge.
3.6V 3350mAh.
There is foam at the end of the battery pack for buffer and insulation.
The synchronous buck-boost chip, toroidal core inductors, solid capacitor, and protocol chip are on the front of the PCBA.
And the battery protection chip and MCU are on the back.
ChargerLAB found it adopts a buck-boost circuit for charging and discharging the battery,
and a buck circuit for fast-charging output.
This chip is from Powlicon, which is a bidirectional synchronous buck-boost converter with two built-in MOSFETs.
40V 9mΩ each.
And these two MOSFETs that work with it are from kwansemi and adopt PDFN3333 package.
40V 7mΩ.
The buck-boost toroidal core inductor is insulated by a heat-shrinkable tubing.
And those two solid capacitors are used for output filtering.
220μF 35V.
The protocol chip is from Chipsea Tech, which is a USB-C controller that supports PD3.0
and suitable for multiple fields.
This VBUS MOSFET is also from kwansemi and adopts PDFN3333 package.
30V 10mΩ.
The synchronous buck converter for the buck circuit is from iSmartWare.
It can support multiple charging protocols.
The buck toroidal core inductor is insulated by a heat-shrinkable tubing.
And here is a black filter capacitor.
220μF 35V.
Flip to the back.
The MCU used for overall control is from Eastsoft,
which is a 32-bit high-performance, low-power MCU with an M0 core.
And it adopts QFN32 package.
These are the four LED indicators.
The protection chip is from CellWise,
which is a lithium battery protection chip with built-in high-precision detection circuit and delay circuit.
And those three battery protection MOSFETs are from kwansemi.
This 5mΩ current sensing resistor adopts2512 package.
This battery protection chip is also from CellWise,
which provides voltage, current, open wire and temperature protections.
Well, that's all components of this mophie 45W powerstation pro power bank.
The rectangular design with the premium woolen texture makes it fits in your laptop bag easily for a long trip.
And with two USB-C ports and up to 45W output,
you can charge your laptop and phone at the same time.
OK, that's all for today's video.
