Hi, guys. Today, we will tear down the Oneplus Warp Charge 65W power adapter,
which is firstly appeared on the OnePlus 8T, and then the OnePlus 9 Pro.
Except for the 65W Warp Charge, it also supports PD and PPS fast charging to
be compatible with more devices.
This 6.5A cable is required if you wanna charge your Oneplus phone.
Ok, let's start today's video.
We can see it adopts, yeap, common flame-retardant PC, and white shell.
The surface adopts glossy design, and the corners are rounded.
which is quite simple.
The "Warp Charge 65" is printed here.
There are some specifications printed here.
Model is WC065A11JH.
And it supports input of 100-240V~50/60HZ 1.8A and output of 5V3A, 10V6.5A.
65W MAX.
The USB-C port is not in the center.
Then, let's see the size.
The length of the charger is 56mm (2.2 inches). Width is 55mm (2.17 inches).
Thickness is 32mm (1.26 inches). The weight is about 118g (4.16 oz).
Compared with Apple 61W charger, this one is much smaller.
Use ChargerLAB POWER-Z KT002 to test the USB-C port.
We can see it supports Samsung 5V2A, DCP, and QC2.0, QC3.0, PD3.0, PPS protocol.
And it also shows it has five fixed PDOs of 5V3A, 9V3A, 12V3A, 15V3A, 20V2.25A,
and one PPS PDO of 3.3-16V 3A.
Next, let's test its compatibility.
Since it comes with 45W PD, and PDO is also complete.
So you can charge your iPhone or Android phone, including tablets and laptops.
But 45W might not be enough for some high-performance laptops.
Ok, let's go ahead and tear it down.
Remove the shell, and the fixed pins are connected to PCB through wire, and fixed by glue.
There're lots of thermal adhesives between the components on the front.
The transformer is covered with a heat sink,
and there is a plate to isolate the primary and secondary circuits.
Turn it back. We can see there are insulating plates and heat sinks on the back of the PCB.
This is the insulation plate.
The components on the secondary side
are covered with thermal adhesives to enhance heat dissipation.
After cleaning up, we can see the secondary synchronous rectifier controllers and MOSFET.
ChargerLAB found this OnePlus charger uses switching power supply for output.
And then, the protocol chip controls the output voltage through the optocoupler.
Then, let's start from the input to introduce every single components.
There are fuses, X capacitors, common mode chokes, and rectifier bridge on the right side of the PCB.
And those two Y capacitors are placed between the primary and secondary sides.
Here are I-shaped inductor and three electrolytic capacitors.
This heat sink is used to dissipate heat for the high-voltage MOSFET.
The specification of the fuse is 3.15A 250V.
The surge suppression resistor is in the shrinkable heat tube,
used to suppress surge current.
The common mode chokes are used to filter out EMI interference.
The Safety X capacitor comes from STE Electronics.
This is the rectifier bridge.
I-shaped inductor is in the shrinkable heat tube.
Those two brown electrolytic capacitors come from AiSHi,
400V 18μF.
The larger black capacitor also comes from AiSHi,
400V 47μF.
The thermal resistance temperature for both of them is 115℃ (239 ℉).
The power supply capacitor of master control chip is 100V 10μF.
The master control chip is ON Semiconductor NCP1342,
which is a high-frequency primary PWM controller
with built-in active discharge capacitor and multiple protection functions.
Then, let's remove the heat sink and clean up the thermal adhesives.
The primary switch MOSFET comes from STMicroelectronics STF13N65M2
and adopts TO220FP package.
650V, 0.43Ω.
This is the transformer.
The optocoupler, Everlight EL1019,
is placed between the primary and secondary circuits to regulate output voltage.
The small PCB of USB-C port is welded vertically,
and three solid capacitors on the left side
are isolated by a black plastic plate to the transformer.
There are two blue Y capacitors for anti-interference,
which are connected in series to increase the withstand voltage.
The secondary synchronous rectifier controller comes from ON Semiconductor NCP4306,
which supports up to 1MHz switching frequency,
multiple working modes, and GaN synchronous rectifiers.
And the secondary synchronous rectification MOSFET comes from AOS Semiconductor.
The Schottky diodes, PS10100LT,
are connected in parallel with synchronous rectifiers to improve efficiency.
There are solid capacitors.
This one is 25V 680μF.
And those two are 25V 560μF.
The output VBUS switch MOSFET on the small PCB,
and the USB-C port has a red rubber seal ring.
The protocol chip and current detection resistor are on the other side.
Finally, the output VBUS switch MOSFET adopts AOS AON7400A.
Well, that's all components of this Oneplus charger.
It works perfectly with the Oneplus charger.
And it also can charge iPhone, Android devices, tablets, and laptops.
So, you can even just bring one charger when you go out.
If you lost your charger or wanna buy a spare,
the retail price of this charger is $34.99, which is available on Oneplus official website.
I'll put the link in the description. Feel free to check it out.
