Recently, AENZR launched a 130W GaN charger.
Unlike most multi-port high-power chargers,
all those four output ports are USB-C.
And it didn’t have any USB-A ports.
It reduces the charger compatibility somewhat.
But you can say goodbye to the old USB-A port.
Let’s tear off the plastic film and introduce this charger to you.
The front of the box is printed with the “AENZR” and “130W GaN Fast Charge”.
Here is the charger.
The compatible devices are printed on the side.
All the features and specs info are on the back.
We’ll talk about it later.
Take it out.
Except for the charger itself, it also comes with a power extension cord.
First, let’s take a look at the charger.
It adopts black matte plastic with “AENZR” in the center.
All the specs info are printed on the side.
Model is AZ1130.
It supports input of 100-240V~50/60HZ 2A.
And the USB-C1/C2 can go up to 50W output, while the USB-C3/C4 can go up to 100W output.
If you charge four devices at the same time, the power will be divided into 20W, 20W, 30W, and 60W.
130W in total.
The input prongs can be folded.
All four USB-C ports are on the opposite side, with an indicator light on the bottom.
Then, let’s take a look at the power extension cord.
Its length is about 1.5m (4’ 11.1”).
The plug has a U-shaped slot and two clips on both sides to fix it.
You can flip the clip at the top to remove it from the charger.
Slide the plug into the input end.
It turns into a charging station and can be placed on your desktop.
The size of the charger is about 74 x 74 x 32 mm (2.91 x 2.91 x 1.26 inches).
Compared with the Apple 140W charger, the size is slightly smaller.
But it can charge up to four devices at once.
The weight of the charger is about 239g (8.43 oz).
The ChargerLAB POWER-Z KM002C shows the USB-C1 supports Apple2.4A,
Samsung 5V2A protocols, and QC3.0, QC5, AFC, SCP, PD3.0, PPS fast charging protocols.
And it also has five fixed PDOs of 5V3A, 9V3A, 12V3A, 15V3A, 20V2.5A, and a set of PPS.
The USB-C2 can support the same protocols as the USB-C1.
And the PDO info is also the same.
Then, the KM002C shows the USB-C3 supports QC3.0, QC5, AFC, FCP, SCP, PD3.0, and PPS fast charging protocols.
It also has five fixed PDOs of 5V3A, 9V3A, 12V3A, 15V3A, 20V5A, and a set of PPS.
The supported protocols and PDO info of the USB-C4 are the same as the USB-C3.
The USB-C1 port of most multi-port chargers can output the peak power.
But this charger is the opposite.
So, please check it carefully before using it.
Next, let’s go ahead and take it apart to see how it can support four USB-C ports at the same time.
Start from the bottom cover.
Use the spudger to pry along the gap and remove it.
Then, the internal module can be easily taken out.
The entire module is wrapped with brass heat sink for heat dissipation.
Cut off the red and black wires and disconnect them from input prongs.
Then, remove the brass heat sink on the front and back side.
We found the internal components are filled with silicone adhesives for heat dissipation and fixing.
Two black Mylar sheets are inserted into the PCB’s slot to insulate the primary and secondary sides.
ChargerLAB found this charger has the PFC circuit.
And the LLC topology of the switching power supply can output a fixed voltage.
Then, the fixed voltage will be rectified by the synchronous rectification circuit.
The time-delay fuse is from Better Electronics. 5A 250V.
The green common mode choke can suppress the EMI interference.
The X2 safety capacitor is 0.47μF.
And the second common mode choke is larger than the first one and is wrapped with tape for insulation.
Two bridge rectifiers are sholdered on a small vertical PCB.
They’re connected in parallel to form the half bridge circuit and can share the heat evenly.
The output filter inductor is under the second common mode choke.
And the red film capacitor is from TQCAP. 1μF 450V.
This is the 2-in-1 primary controller from MPS HR1211,
which integrates multi-mode PFC controller and current mode LLC controller.
It integrates bootstrap diode, and the specs info can be configurable.
This GaN IC is from Navitas and is used for PFC boost.
It adopts QFN 6 x 8 package and the heat dissipation performance has been improved.
650V, 125mΩ.
Those two current sampling resistors are connected in parallel
and are used to detect the current of the PFC boost GaN IC.
The resistance is 100mΩ.
The PFC boost inductor is tightly wrapped with tape for insulation.
The PFC boost rectifier is from Global Power and adopts DFN 5 x 6 package.
And the maximum operating temperature is 175℃ (347°F).
650V, 4A.
The electrolytic capacitor for high-voltage filtering is from Chn Cap.
82μF 450V.
And the solid capacitor that powers the primary controller is also from Chn Cap.
35V 100μF.
Those two LLC MOSFETs are from Lonten and adopt PDFN 8 x 8 package.
They can form the half bridge circuit. 700V 180mΩ.
The resonant capacitor is 0.022μF 630V.
And here is the LLC resonant inductor.
And then, the LLC transformer is tightly wound with tape.
The low-voltage side is connected to the synchronous rectification PCB through two black wires.
The white optocoupler is used for output voltage feedback.
The SMD Y capacitor is from TRX.
The LLC synchronous rectifier controller is from MPS.
It integrates two controllers,
which are used for synchronous rectification of two secondary coils, respectively.
Those two synchronous rectifiers are from Hunteck and adopt DFN 5 x 6 package.
65V, 3.8mΩ.
Those two solid capacitors are connected in parallel and also from Chn Cap.
25V 680μF.
There’re four secondary buck PCBs, corresponding to four USB-C outputs.
Since the maximum output power is 50W and 100W.
So, there’re two types of output PCB.
This is the 100W output PCB.
The protocol chip is from Ismartware, used for step-down control and protocol identification.
And two buck MOSFETs are from Ruichips and adopt PDFN3333 package.
40V, 5.5mΩ.
The solid capacitor for output filtering is also from Chn Cap.
25V 220μF.
Then, this is the 50W output PCB.
The protocol chip is also from Ismartware but in a different model.
It integrates a 3.5A synchronous rectification buck converter
and supports various charging protocols.
This solid capacitor is the same as the one on the 100W output PCB.
The USB-C connector is from KRCONN.
Finally, the 32-bit MCU with M0 core is from Chipsea,
which is responsible for the automatic power distribution of each USB-C port.
Its maximum operating frequency is 24MHz, and it adopts QFN20 package.
Well, that’s all components of this AENZR 130W GaN charger with four USB-C ports.
After taking it apart, we found it adopts LLC topology
and integrates four independent output PCBs to support four USB-C ports.
If you’re really fed up with the old USB-A ports and want to move into a new era of USB-C,
you might consider this charger, but make sure all your devices support USB-C.
OK. That’s all for today’s video.
