Hi, welcome back to our channel.
Today, our protagonist is a power strip made by Anker.
It’s a UK power strip with 18W USB-C.
It continues the blue and white of Anker style.
There are some product features and other information on the back.
Open the box.
We can see it adopts the traditional shape. And the plastic shell is matte.
Here is the grey power button.
And there’re two indicator lights next to it.
The “Surge Protection” is printed here, which means it can support this function.
The AC pins are UK standard.
And one USB-C and two USB-A are on the other side and adopt Anker blue.
Here is the product info. Model is A9136.
It supports input of 250V~ 50/60HZ 13A.
Output of USB-C is 18W.
Output of USB-A is 12W.
Surge protection is 6kV.
Voltage protection level is 1.5kV.
Maximum operating voltage is 255Vac.
It has passed the UKCA and CE certification.
The specs of power cord is 3G1.5mm², 300/500V.
The plug integrates fuse and also adopts the UK standard.
The power cord length is about 2 m (6’ 6.74”).
And the length of socket is about 32cm (1'0.6'').
Width is 6.2cm (2.44 inches).
Thickness is 2.7cm (1.06 inches).
Weight is 596.8g (1.32 lb).
Use ChargerLAB POWER-Z KT002 to test the USB ports.
Both USB-A can support Apple 2.4A, Samsung 5V2A, DCP protocols.
And USB-C supports Apple 2.4A, Samsung 5V2A, DCP protocols.
and QC2.0/3.0, AFC, FCP, PE2.0, PD3.0 fast charging protocols.
The PDO of USB-C is 5V3A and 9V2A.
Then, let’s use the 18W USB-C to charge some devices.
Next, let’s tear it down.
Remove the screws and open the bottom shell.
The left input joint is fixed by two screws.
Three AC sockets adopt three copper strips
to connect the live, neutral, and ground wire, respectively.
The PCB of USB ports is also fixed by screws.
Remove the right PCB.
There’re apparent gaps between front components.
And the bridge rectifier, master control chip,
and synchronous rectifier are on the PCB’s back.
The specs of time-delay fuse is 2A 250V.
The common mode choke is used to filter out EMI interference.
The NTC thermistor is used to suppress inrush current.
Three electrolytic capacitors come from Aishi.
400V 15μF.
The transformer comes from Huntkey.
Two solid capacitors come from APAQ.
16V 330μF.
The other electrolytic capacitor is also from Aishi.
400V 15μF.
And the other transformer is also from Huntkey.
The third solid capacitor is 6.3V 1000μF.
This is the first non-MCU and QC5 certified protocol chip.
Model is Ismartware SW2303.
It has high integration and can support USB-C and USB-A.
This is the output VBUS MOSFET. And this is the RABS210 bridge rectifier.
The master control chip comes from On-Bright OB2631U.
It integrates PWM controller and MOSFET.
It is also optimized for high-performance,
low power consumption switching power supply.
The secondary synchronous rectifier adopts On-Bright OB2004Ax.
It integrates MOSFET and supports output of 3-12V.
The master control chip of USB-A circuit adopts Chipown PN8386.
It consists of a Low Standby-Power Quasi-Resonant (QR) Primary-Side controller
and a 650V avalanche-rugged smart power VDMOSFET,
specifically designed for high-performance AC/DC chargers.
This is the synchronous rectifier from Chipown PN8306H.
It integrates MOSFET and can support DCM and QR working modes.
It also provides under-voltage protection, over-voltage clamping.
This is automatic identification IC of dual USB.
Model is Semihigh UC2634.
Finally, let’s solder the wires back.
And everything has been restored.
So, after taking it apart. We found taht the USB-C and USB-A adopt two
independent circuits, which ensure the USB-C can fully output.
The USB-C circuit adopts On-Bright components and Ismartware protocol chip.
And the USB-A circuit adopts Chipown components.
Both circuits adopt the Aishi capacitor. So, the overall quality is pretty nice.
Okay, that’s all for today’s teardown video.
