We've posted several videos about chargers and power banks from Anker GaNPrime series.
And today, we got our hands on a three ports 65W GaN charger from GaNPrime series.
It adopts industry's first all-GaN technology to improve performance massively.
So let's see how it can achieve this.
The package continues GaNPrime series design.
And some specs info are printed on the side.
Tear off the sealing strip and open the box.
Just like the 140W and 120W,
It also comes with some documents and a rubber pad,
which can fix the charger on the wall outlet more tightly.
And it won't fall off even if we shake it.
The ANKER and GaNPrime are printed on the black matte surface.
And two USB-C and a USB-A ports are on this silver panel.
And then, let's take a look at the specs info.
Model is A2668.
It can support input of 100-240V 50/60HZ 1.8A,
and the output can be up to 65W.
It also has passed different certifications.
You can pause to take a look.
The size of the charger is about 66 x 29 x 38mm (2.60 x 1.14 x 1.50 inches).
So, the power density is about 0.88W/cm³.
Compared with Apple 61W charger, the size is almost half of it.
And the weight is about 123g (4.34 oz).
ChargerLAB POWER-Z KM002C shows the USB-C1 supports FCP, SCP,
AFC, QC3.0+, QC4+, PD3.0, PPS, Apple2.4A and Samsung 5V2A protocols.
And it also supports four fixed PDOs of 5V3A, 9V3A, 15V3A, and 20V3.25A, and a set of PPS.
Switch to the USB-C2.
The protocols and PDO info of those two ports are exactly the same.
So, you can choose any USB-C port to get the maximum power.
As for the USB-A port, it supports FCP, SCP, AFC, and QC3+ protocols.
Next, let's go ahead and take it apart to see how did Anker achieve all-GaN technology.
As always, use the spudger to pry along the gap.
You can find lots of pink silicone adhesives inside, which is good for consumers, but not for the teardown.
So we have to use the cutting machine to cut it off.
After taking out the PCB module, we found the entire module is covered with pink silicone adhesives,
just like other Anker chargers.
Some white plastic tapes are pasted inside the shell.
Clean off all silicone adhesives.
The black and white wires are connected to the input PCB.
All plug-in components are on the front.
And the transformer is in the middle.
A GaN IC, optocoupler, and SMD Y capacitor are soldered on the back.
ChargerLAB found it adopts a QR flyback topology.
And the secondary synchronous rectifier also adopts GaN technology.
The input fuse is from Better Electronics for input overcurrent protection.
5A 250V.
And the common mode choke is wound with magnet and insulated wires.
The safety X2 capacitor is from DGCX.
0.15μF.
This SMD bridge rectifier can convert AC into pulsed DC.
Those five filter capacitors are from Yongming. 22μF 400V.
110μF in total.
And the I-shaped differential mode choke is insulated with a heat-shrinkable tube.
The master controller is actually a GaN IC from Southchip and adopts QFN6 x 8 package.
It can save more space with built-in driver.
Here is the transformer, tightly wrapped with tape.
And these two SMD Y capacitors are from HolyStone.
They're connected in series to improve withstand voltage.
The optocoupler is used for output voltage feedback.
And a blue Y capacitor is soldered to the edge of the PCB.
Remove most of the components on the front.
So, we can take a closer look at the synchronous rectification controller.
It can drive the GaN synchronous rectifier directly and comes from Southchip.
It also supports turn-on detection and fast turn-off.
The synchronous rectifier is from Innoscience, which is a GaN power transistor.
150V 7mΩ.
Those two solid capacitors for output filtering are from Yongming NPT series.
470μF 25V.
The 32-bit MCU with built-in M0 core is from Eastsoft and adopts QFN32 package.
It features high performance & low power and can be used for internal temperature detection and protection.
Here is the small PCB for USB-C1 port.
The buck inductor, filter capacitor, and some MOSFETs are on the front.
While the protocol chip, MOSFETs, and current sense amplifier are on the back.
The protocol chip is from Ismartware, which integrates a 7A synchronous buck converter.
The buck MOSFET is from AOS and adopts DFN3 x 3 package.
40V 5mΩ.
And the current sense amplifier is from SG Micro, used for output current sampling.
Another same AOS buck MOSFET is on the front. AONR66406
This is a 4.7μH alloy buck inductor.
The solid capacitor for output filtering is from Yongming and is insulated with heat-resistant tape.
The output VBUS MOSFET is also from AOS.
The plastic sheet inside the USB-C connector is Anker blue.
Moving to another PCB of USB-C2.
The filter capacitor, buck inductor, and some resistances are on the front.
The protocol chip, USB-C connector, and VBUS MOSFET are on the back.
The protocol chip from Ismartware is the same as the USB-C1.
But this one is for USB-C2 and USB-A output.
Those Two buck MOSFETs are also from AOS.
Another 4.7μH alloy buck inductor is here.
The solid capacitor is also from Yongming. 470μF 25V.
Those two current sense amplifiers are also from SG Micro, same as the USB-C1.
This VBUS MOSFET is also from AOS, used for USB-C2.
Finally, here is the USB-A connector, which is also in Anker blue.
No component on the back.
Well, that's all components of this Anker three ports 65W GaN charger.
After taking it apart, we found the internal components are filled with silicone adhesives,
making the charger more durable.
And except for the GaN IC on the primary side,
it also integrates GaN synchronous rectifier to achieve an all-GaN design.
OK. That's all for today's video.
