Hi guys, welcome back to today's video.
If you have been subscribing to our channel for a long time,
you will notice that we have made several videos for the Anker GaNPrime series.
And today, we got a 65W GaN power strip, also from GaNPrime series.
So let's go ahead and check its internal structure.
This time, Anker changed its packaging from black to white.
Flip to the back.
A few selling points of Anker are printed on the top.
And some specs info are printed on the side.
Tear off the sealing strip and open the box.
It contains the power strip and some documents.
The power strip adopts a white round design and has a built-in power cord.
The plug can be plugged into the outlet on the top, which is convenient for carrying around.
There is a hidden slot under the rubber sleeve.
So, the power cord can be stored around the power strip.
Two USB-Cs, one USB-A, and the AC outlet are on the top.
The plastic sheets inside the USB ports are all Anker blue.
Another AC outlet is on the bottom.
Unwrap the power cord around it to see the specs info.
Model is A9125.
For the AC part, rated current and power can be up to 10A and 2500W, respectively.
The USB module can support input of 100-240V~50/60Hz 2A.
The USB-A can support up to 12W, while the USB-C can support up to 65W.
You can pause here to take a look.
The size of the power strip is about 113 x 55 x 47mm (4.45 x 2.17 x 1.85 inches).
The power cord length (including the plug) is about 88cm (34.65 inches).
And the weight is about 330.5g (11.66 oz).
Connect it to the ChargerLAB POWER-Z KM002C.
It shows the USB-C1 supports QC3.0, PD3.0, PPS, Apple 2.4A, Samsung 5V2A protocols.
And it also supports four fixed PDOs of 5V3A, 9V3A, 15V3A, 20V3.25A, and a set of PPS.
Switching to USB-C2.
We can see the protocols and PDO info of those two ports are exactly the same.
So you can use any USB-C port to get the maximum power.
And the USB-A port supports Apple 2.4A and Samsung 5V2A protocols.
Next, we gonna take it apart to check its internal components and structure.
Use the spudger to pry along the gap and remove the plastic cover.
There're two screws to fix the panel.
Unscrew these screws.
And remove the top cover.
As you can see, the rubber sleeve and top cover are joined together.
The AC module is on the left. And the USB module is on the right.
Remove the remaining screws.
And take out the internal module.
The AC module is insulated with plastic shell.
And there is a piece of white foam attached to the inner frame under the USB module for buffering.
And the AC module is connected to the USB module by wires to provide power.
The USB module is filled with silicone adhesives, which can insulated from the brass heat sink by Mylar sheet.
Remove the heat sink.
These silicone adhesives can enhance heat dissipation,
as well as fix internal components to reduce falling damage.
Clean up the USB module.
First, let's introduce the USB module.
It's composed of multiple small PCBs, making the size even smaller.
The primary and secondary PCBs from the top and bottom are independent and insulated by a plastic bracket in the middle.
And there are two small PCBs on top of the module for output.
ChargerLAB found it adopts a QR flyback topology.
And the secondary synchronous rectifier also adopts GaN technology
to achieve the "full-GaN" design.
There're two independent synchronous buck circuits for output.
So, you can use either of the USB-C ports to get the maximum 65W.
Next, we will take apart the PCBA module to introduce all components.
The fuse, safety X2 capacitor, and common mode choke are on the back.
The time-delay fuse is insulated with heat-shrinkable tube.
3.15A 250V.
And the safety X2 capacitor is from DGCX. 0.15μF.
The common mode choke is wound with magnet and insulated wires.
And there are two diodes under it.
Two Pingwei bridge rectifiers are on the front of this small input PCB.
They form a half-bridge circuit to dissipate the heat evenly, used to rectify AC into pulsed DC.
3A 1000V.
Moving on to the primary PCB of USB module.
Four electrolytic capacitors are from Yongming.
Three of them are 33μF 400V.
The remaining one is 22μF 400V.
So 121μF in total.
And the differential mode choke is wound with an I-shaped magnetic core and is insulated with a heat-shrinkable tube.
This primary controller is actually a GaN IC from Southchip and adopts QFN6 x 8 package.
The tiny capacitor that powers the primary controller is from AiSHi.
50V 10μF.
Here is the transformer.
Next, this SMD Y capacitor is on a small output PCB, from TRX.
An optocoupler is below it, used for output voltage feedback.
Then, we have the secondary buck PCB for output.
Those two slots next to the USB-A correspond to two small PCBs of USB-C.
The buck converter, synchronous rectifier controller, and overcurrent protection chip are on the back.
The synchronous rectifier controller is from Southchip.
And it supports turn-on detection and fast turn-off.
The synchronous rectifier is actually a GaN power transistor from Innoscience.
It features low gate charge and ultra-low on resistance.
150V 7mΩ.
These two solid capacitors for output filtering are from Yongming NPT series.
They're connected in parallel. 560μF 25V.
And those two small output PCBs are exactly the same.
The buck MOSFET, USB-C connector, and output filter capacitor are on the front.
The buck inductor and charging chip are on the back.
This is a highly integrated multi-protocol charging chip from Ismartware,
used for buck output.
Those two buck MOSFETs are from AOS and adopt DFN3 x 3 package.
30V 4.1mΩ.
And the buck inductor is insulated with heat-shrinkable tube.
The solid capacitor for output filtering is from Yongming NPT series
and is insulated with heat-resistant tape.
220μF 25V.
The output VBUS MOSFET is the same model as the buck MOSFET but with different functions.
A Y capacitor is connected between two USB-C connectors.
The USB-C connector is Anker blue.
Back to USB-A.
The synchronous buck converter for USB-A is from Toll Microelectronic and integrates MOSFET.
It supports 30V input, and up to 3.5A output.
This is the solid capacitor for input filtering.
220μF 25V.
Another solid capacitor for output filtering is here.
220μF 10V.
The buck inductor for USB-A is also insulated with heat-shrinkable tube.
This current limiting IC of the USB-A is from CellWise.
It's used for automatic identification and short-circuit protection.
The USB-A connector is also in Anker blue.
Finally, the 32-bit high-performance MCU is from Eastsoft,
which integrates an M0 core and ADC.
It's used for internal temperature detection & protection and adopts QFN32 package.
It's also used to distribute the power of each port automatically.
Well, that's all components of this Anker 65W GaN power strip from GaNPrime series.
The mini design and impressive way to store the power cord can improve desktop utilization.
After taking it apart, we found the internal layout is pretty compact.
And the mini design is achieved by six tightly stacked PCBs.
Also, the "full-GaN" design gives it a high switching frequency for better performance.
OK. That's all for today's video.
Feel free to click the corners to check the teardown of other GaNPrime products.
