ChargerLAB has published several teardown videos of Anker chargers in the past.
And today, we got another brand new Anker 100W GaN charger,
which is equipped with two USB-C ports and a USB-A port.
Let’s try to take it apart and check what’s inside.
The packaging continues the classic blue and white.
And the selling points, name, model and certification are on the back.
Open the box. Here’re the charger and manuals inside.
The charger continues the design of the Anker’s series 7,
with a black-gray shell with the top silver panel.
All of those three ports are blue.
It adopts fixed prongs.
And here are the specs info.
Model is A2145.
And here is the charging guide.
The charging power will be automatically distributed when you use different ports.
You can pause to take a look.
The size of this charger is about 56x66x31mm (2.2x2.6x1.22 inches).
So, the power density is about 0.83W/cm³.
And the weight is about 205g (7.23 oz).
And then, the three ports Anker charger is even smaller than single-port Apple 96W charger.
The ChargerLAB POWER-Z KT002 shows the USB-C1 can support QC2.0/3.0,
FCP, SCP, PE2.0, PD3.0 and PPS protocols.
It also supports four fixed PDOs of 5V3A, 9V3A, 15V3A, 20V5A, and a set of PPS.
And the USB-C2 is the same as USB-C1.
The USB-A supports QC2.0/3.0, FCP, SCP, PE2.0 protocols.
Ok. And the next step is to take it apart to see what’s inside.
Pry along the gap.
We can finally remove the top case.
We can see lots of silicone adhesives inside.
The PCBA module is covered with copper heat sinks.
The red and black wires are connected to the input prongs.
Let’s remove the heat sink on both sides.
The front and back components are covered with silicone adhesives for fixing and heat dissipation.
And then, let’s clean up the silicone adhesives.
Now, ChargerLAB found it adopts QR topology and has PFC circuit.
The secondary step-down circuit can adjust the output power of each port.
Then, let’s start from the input to introduce all components.
Firstly, the time-delay fuse is from Better Electronics.
3.15A 250V.
The first common mode choke is used to suppress EMI interference.
The safety X2 capacitor is from DGCX.
0.47μF.
The second common mode choke is slightly different from the first one.
And then, the bridge rectifier is from Pingwei, which can convert AC into pulsed DC.
8A 1000V.
The first film capacitor is 1.2μF 450V.
And the second one is from DGCX.
1μF 450V.
This is the toroidal-core inductor.
This charger is equipped with PFC circuit.
And the PFC controller is from ON Semiconductor,
which operates in the critical mode with enhanced high-efficiency.
The PFC GaN IC is from Navitas NV6136A,
which integrates the current sampling technology and driver.
It adopts QFN6*8 package and can support 2MHz switching frequency.
170mΩ, 10-30V.
The PFC boost rectifier is a fast recovery diode.
Here is the PFC boost inductor.
This electrolytic capacitor is from AiSHi and is used for PFC output filtering.
420V 120μF.
The primary controller is from Southchip SC3022D,
which is a high-frequency QR flyback controller.
It integrates X capacitor discharge and high-voltage startup.
It also provides an adaptive switching frequency fold-back to achieve higher efficiency
in the whole loading range.
The primary switch transistor is also from Navitas NV6136A,
same as the PFC GaN IC.
The transformer is tightly wound with insulating tape.
Here is the EL1018 optocoupler for the feedback of output voltage.
Two SMD Y capacitors are on the top and middle of the PCB, from Anshan KeiFat.
Two parallel synchronous rectifiers are from Vergiga, which adopts PDFN5060 package.
120V, 6.5mΩ.
The synchronous rectifier controller is marked with 903A and adopts SOT23-6 package.
Two solid capacitors are soldered vertically on the PCB for output filtering.
The first one is 680μF 25V.
And the other one is 470μF 25V.
Then, the pulsed DC will be sent to those secondary step-down PCBs, three in total.
Since both USB-C ports can support 100W, those two PCBs are identical.
The filter capacitor and inductor are on the front.
And the master control chip of two USB-C ports is from Ismartware SW3516H
and used for step-down control and protocol identification.
There’s a MOSFET for the USB-C port from AOS.
30V, 6.3mΩ.
Those two MOSFETs are used for synchronous rectification and step-down, marked with S4480.
The output VBUS MOSFET is from AOS and adopts DFN3x3 package.
30V, 5mΩ
Finally, the solid capacitor on the front is from Yongming NPT series.
220μF 25V.
And then, this is the secondary step-down PCB of the USB-A port.
The protocol chip is the same as USB-C port, from Ismartware.
Those two synchronous step-down MOSFETs are the same as USB-C ports.
And the solid capacitor is also the same as USB-C ports.
The USB-A socket is blue.
There’s a Chipsea MCU on the secondary side for power distribution,
overheating protection and PFC control.
It also integrates 12-bit ADC and LED driver.
The thermistor is used to detect the temperature of the transformer.
Well, that’s all for this Anker 100W charger.
It’s equipped with two USB-C ports and a USB-A port.
So, you can charge your phone, tablet and laptop at the same time.
Since it’s pretty small and can support up to 100W,
it takes many measures to control the temperature.
For example, it’s filled with silicone adhesives.
And there’re pure copper heat sinks on the front and back sides.
After taking it apart, ChargerLAB found it adopts Chipsea MCU to control the output power.
And most components are from some famous brands, like Navitas, Vergiga,
ON Semiconductor, Southchip, AiSHi, Ismartware, etc.
Ok. That’s all for today’s video.
