Hi, guys. Welcome back to today's video.
As we all know, ChargerLAB has taken apart lots of laptop power adapters from some well-known brands.
But today, we got our hands on this fake HP 65W power adapter.
And we decided to take it apart and see if it could match the quality of adapters from other mainstream manufacturers,
such as MSI.
It's wrapped with a built-in USB-C cable.
Firstly, tear off all plastic films.
It adopts a classic HP laptop power adapter design with a matte and glossy surface.
And the nameplate is attached to the back.
Model is TPN-DA13.
It can support input of 100-240V~50/60Hz 1.6A.
The USB-C output can be up to 20V3A, which is 60W.
And the USB-A can provide 5V1A.
It has passed multiple certifications.
It also says the manufacturer is Delta.
But I don't think so.
So we will test the adapter to see its actual specs info.
The detachable three-prong design can protect the user from electric shock.
A USB-A port is next to the USB-C output cable.
There is a slot at the junction to fix and protect the output cable.
And there is a hasp to arrange the cable.
The woven cable also adopts the same white and black design as the original one.
The size of the adapter is about 97.8 x 54 x 21.5mm (3.85 x 2.13 x 0.85 inches).
The length of the USB-C cable is about 1.71m (5' 7.32").
Connect it to the ChargerLAB POWER-Z KM002C.
It shows the adapter supports PD3.0, PPS, and QC5 protocols.
And it also supports five fixed PDOs of 5V3A, 9V3A, 12V3A, 15V3A, 20V3.35A, and a set of PPS.
And the USB-A port doesn't support any fast-charging protocol.
That means the nameplate is correct, at least in the output part.
Next, let's take it apart and check out the internal components.
As always, use a spudger to pry along this side of the gap and open it up.
Only one of the three black wires is insulated with tape.
Continue to open the other side.
Cut off those output wires and take out the PCBA module.
We can see it's insulated with some yellow tapes.
Tear them all off.
There's a gray thermal pad on the back of the PCBA for heat dissipation.
The fuse, safety X2 capacitor, common mode choke and filter capacitor are on the front of the PCBA.
Flip to the back.
The rectifier, controller and optocoupler on the back.
ChargerLAB found it adopts QR flyback topology.
After the synchronous rectification, it can output a wide range of voltage controlled by the protocol chip.
The input fuse is from CONQUER MST series. 3.15A 250V.
The safety X2 capacitor next to it is from CARLI. 0.1μF.
And these two common mode chokes are insulated with flat copper wires.
The bridge rectifier is from World Industrial.
It can quickly dissipate the heat and adopts LSB package.
This is a big filter electrolytic capacitor. 82μF 400V.
The primary PWM controller of the high-frequency QR flyback topology is from ON Semiconductor.
And the GaN FET next to it is from XINGUAN and adopts DFN8x8 package. 650V 230mΩ.
This huge transformer is insulated with tape.
And the blue Y capacitor is from JNC.
This optocoupler is used for output voltage feedback.
The synchronous rectifier is from JieJie Micro and adopts PDFN5*6-8L package.
100V 9.2mΩ.
Those two filter solid capacitors connected in parallel are from HYNCDZ.
680μF 25V.
The protocol chip is from Canyon, which is actually a highly integrated USB PD fast-charging controller.
And the VBUS MOSFET below it is from AOS, which adopts DFN3*3 package. 30V 4.1mΩ.
The synchronous buck chip is actually a DC to DC converter from EUTECH,
which can operate in CC(constant current)/CV(constant voltage) mode.
It is used for USB-A output and adopts SOP-8 (EP) package.
And this small solid capacitor for output filtering is from PolyCap RN series.330μF 6.3V.
Well, that's all components of this fake HP 65W power adapter.
After taking it apart, we found the internal heat dissipation measures
were obviously not as good as the original MSI power adapter we took apart before.
And some components are from unfamiliar manufacturers.
But it's also not as bad as we thought before the teardown.
So, we do not recommend buying these fake products if you have enough budget.
OK. That's all for today's video.
