Recently Anker launched its second-generation GaN charger, which is called “Nano II” series.
There are three sizes of 30W, 45W and 65W
and have brand new design, smaller size. The top silver-gray area is the mark of “Nano
II” series, very recognizable. This 65W charger also launched PI’s latest
PowiGaN chip, InnoSwitch4-CZ series, you know, a strong alliance.
Firstly, let’s compare the Apple 61W to this charger.
To be honest, it seems like the products from two different eras.
Let’s take a caliper to measure its size.
Length, width and thickness will be 36, 41 and 44mm.
The weight is 107g. So, we can know the power density is about
0.98W/cm³, very close to one. And the number is very impressive.
Even it’s the GaN charger, and can be that small, and adopts foldable pins, pretty nice.
And then, let’s test the protocol of the charger.
There are four fixed voltage gears: 5V / 9V / 15V / 20V and 5-21V PPS.
And can fast charge some mobile phones that have PPS protocol.
After reviewing this charger, let’s do our job, tear it down.
This time, Mr. Hammer will have a lady, Miss. Spudger.
Use a spudger and a sledgehammer to insert the gap little by little.
Then pry it to open. We can see there are lots of thermal glue
inside, which is very troublesome for our teardown.
Seem like it doesn’t work. So, the only thing we can do is to clean up
the thermal glue and pull it out with pliers. Take out the entire PCB module.
OMG, there are still so many thermal glues. Just continue to clean up and tear it down.
After cleaning up, we can finally see something. Ok, let’s see what’s inside.
Firstly, look at the small board for input. There are three components on this side.
The first one is a fuse, covered by a heat-shrinkable protection tube.
The middle is the safety X capacitor. The last one is the common mode choke.
There are two SMD rectifier bridges on the back, which can reduce the thickness and just
spread the heat. Secondly, we can see its connection board,
which is used to connect input and output boards.
There are four electrolytic capacitors for high-voltage filters.
And then, let’s see the back side. Here is the PI’s latest PowiGaN chip InnoSwitch4-CZ
master chip. It integrates a PWM controller, a synchronous
rectifier controller, and a primary switch MOS tube.
The PI’s ClampZero chip is next to it, which integrates high-voltage switch tube and controller.
Let’s take a look at its electrolytic capacitor for high-voltage filter.
We can see four capacitors totally, Two of them are covered with an insulating
tube for protection. Finally, let’s look at the small board of
output. The two solid capacitors here are also protected
by insulating tube. A synchronized rectifier MOS tube is on the
back, comes from Alpha & Omega AON6220. A Schottky diode is attached next to it.
The protocol chip comes from Weltrend WT6636F. There is also an Alpha & Omega output VBUS
switch tube next to the USB-C port. Finally, let’s take a look at the USB-C
female. There is a black rubber ring on the outside
of the USB-C female for protection After removing it, we can see a separate layer
of steel tube is added to the outside for reinforcement, which can effectively prevent
shedding and provide longer service life.
So, for this Anker Nano II GaN charger, the most impressive thing is the internal thermal
glue of the charger, which can effectively improve the stability and heat dissipation.
This charger used PI INN4075C+CPZ1062M for the first time, which can be more efficient and reduce
temperature. And that’s the reason why it will be so small. So, do you think the Anker
Nano II GaN charger 65W is small enough or not?
Ok, that’s all our teardown. And that’s all components for this charger. If you like
