At the beginning of this month, we released the teardown of Anker “Nano II” series
(65W). There are so many people who wants to see the teardown of other models.
So, today, we bring the teardown of 45W. Let’s go.
Firstly, the box is still the same as 65W, you know, Anker style.
Turn it back. We can see the model is A2664, made in China and some basic information herein.
It supports 5V, 9V, 15V and 20V fixed PDOs. And two PPS PDOs of 3.3-16V3A and 3.3-21V2.25A.
The maximum output is 45W.
The manufacturer is Anker Innovation. Take out the charger from the box. There isn’t
a cable in it, just a charger. The overall shape is like a square.
Just like 65W, there is a small silver area in here.
And overall color is black, adopts foldable pins.
The specifications at the bottom are basically the same as the label on the box.
The entire “Nano II” series uses the same design language
When putting them together, it looks like a brother
Let’s use the caliper to measure the size. Length is 35mm (1.38 inches). Width is 37mm (1.46 inches),
and height is 41mm (1.61 inches). Weight is 69g (2.43 oz).
Compare it with Apple 30W, 61W.
We can see it’s obviously much smaller than those two.
Use ChargerLAB POWER-Z KT002 to test the USB-C port
It supports Apple 2.4A, Samsung 5V2A, DCP, QC2.0/3.0, PD3.0, PPS fast charging protocol.
In addition, there are four fixed and two PPS PDOs, same as the
specification on the box. OK, next step is obviously the teardown.
With the previous teardown experience of 65W We can still use the previous method,
use our spudger and sledgehammer to work together, Pry it.
The thermal glue inside is not as much as 65W,
But still needs to be cleaned up.
Firstly, pull it out with pliers.
Remove the four screws and the AC foldable pins.
The structure is not the same as 65W. The entire PCB module is welded together by
four small boards. Among them, the transformer occupies a small
board. Two larger electrolytic capacitors are covered
with an insulating cover for insulation protection. Remove it while cleaning it up.
Now we have split four small boards. The first is the small input board.
There is an SMD rectifier bridge, which can reduce thickness.
Because the components on the other side have just been removed
So it’s empty right now. Let’s look at the components directly.
This fuse is also protected by a heat shrink tube.
Two electrolytic capacitors for high-voltage filter are behind it.
The second one is the small connecting board. This side is the master control chip of PI,
model is INN3379C, which adopts PowiGaN technology. It also integrates built-in PWM controller,
GaN power tube, synchronous rectifier controller, etc. On the back is a Y capacitor.
The other side of this area is the master control chip.
This area adopts exposed copper to help the master control chip to dissipate heat.
Only one transformer is connected to the other connecting board.
The last is the small output board. Here are two small solid capacitors from the
Yongming NPX series. The synchronous rectifier tube is next to it.
And protocol chip and VBUS switch tube are on the back.
The protocol chip adopts Weltrend WT6636F,
which has PD3.0 certification and supports PPS fast charging.
The output VBUS switch tube comes from Alpha & Omega Semiconductor.
Model is AONR66406. The USB-C receptacle port is soldered in hollow of PCB.
OK, that’s all for our today’s teardown.
Compare to 65W charger, it’s smaller and we can see all components are smaller as well.
So, you can choose the one which most satisfies your needs. If you like this video, please
