Hello everyone! Welcome back to ChargerLAB. Today, we gonna tear down
another Anker 65W charger. The Latest Anker PowerPort III 2-Port 65W Charger.
From the packaging, we can instantly find it’s Anker’s product.
It contains the charger, manual, and certification.
Let’s take a look at the charger directly. The Latest Anker PowerPort III
series has a new black body. The output side’s cover is silver gray.
Anker has launched four chargers this year.
Including the 30W, 45W, 65W of Anker Nano II, and they all have single USB-C.
But this one has two USB-C ports.
If you haven’t seen the teardown of 45W and 65W of Anker Nano II,
you can click the upper right concern to see it directly.
OK, let’s see the design of this charger.
There is an Anker logo. It adopts foldable pins, easy to carry.
There are two USB-C ports can be used. It can support up to 65W when using single port,
and will intelligently distribute the power when using dual port.
Let’s see the specification of the product.
Model is A2666. When using single port,
both USB-C1/C2 can support up to 65W PD fast charging and 52W PPS fast charging.
When using dual port, Maximum output of USB-C 1 is 45W
Maximum output of USB-C 2 is 20W The total output power is still 65W.
Designed by Anker Innovation Technology.
The size of the charger is about 53.5*52*28.8 mm (2.11*2.05*1.13 inches).
The weight of the charger is about 137g (4.83 oz).
Compared with Apple’s 61W charger. This one is more compact.
Compare with previous Anker PowerPort III 2-Port 60W. The new one is also much smaller and more portable.
Let’s use ChargerLABPOWER-Z KT002 to test the USB-C 1 port. It supports Apple 2.4A, Samsung 5V2A, DCP,
QC2.0/3.0, AFC, FCP, SCP, PE2.0, PD3.0, PPS and other protocols.
It also shows four fixed PDOs: 5V3A, 9V3A, 15V3A, 20V3.25A, and one PPS PDO.
We also tested the other USB-C port, which is the same result.
When two devices need to charge at the same time. The maximum power displayed by the USB-C 1 is 45W.
The maximum power displayed by the USB-C 2 is 20W. You can use it to charge the mobile phone
and the laptop at the same time. Suitable for business trips or traveling.
OK, after seeing the design and the performance, Let’s tear it down right now.
After cutting the cover of the input side. We found there are lots of thermally
conductive adhesives inside. PCB module cannot be taken out.
So, we can only continue to cut the shell.
After taking out the internal PCB module.
We really need to clean those thermally conductive adhesives firstly.
OK, That’s it. Let’s see the overall
layout of the PCB, which is quite compact.
The front side has some plug-in components.
It adopts four small PCB to save space. The front side is divided into high-voltage part
and low-voltage part. It can be seen those
two parts are relatively close. So, there is an insulation board in the middle.
On the back, we can see the two main chips and some diodes.
After our analysis, This charger is developed
based on the combination of ACF switching power supply and step-down circuit.
The current comes in from the AC. And then go through the fuse,
common mode chock and safety capacitor. Then, rectify the current by rectifier bridge,
filter the current by capacitor and step-down by transformer.
And rectify and filter it again. Use the second step-down to finally output.
There are two rectifier bridges on the side. High-voltage alternating current is transformed
into high-voltage direct current through the rectifier bridge.
Then, use the high-voltage electrolytic capacitor for filtering.
The four electrolytic capacitors adopt Yongming’s small-sized KCX series.
Two of them are placed on motherboard.
The other two are arranged horizontally on the side PCB.
Three are 400V 33μF, and one is 400V 22μF.
There is also an inductor with an outer insulating tube between the capacitors, used for filtering.
After filtering, the high-voltage direct current will come to the transformer to step-down.
And that’s all components on the front.
The controller is on the back of the PCB.
The master control chip adopts PI InnoSwitch4 series, model is INN4075C.
This is the latest highly integrated chip with built-in GaN from PI.
It is applied to active clamp flyback architecture and can achieve the 0V switch of the main switch
tube and reduce the temperature rise.
PI official data showed,
If this chip is used with PI’s own ClampZero active clamp chip,
it can recover leakage inductance energy and be up to 95% conversion efficiency.
You know, most of the GaN charger’s efficiency on the market is generally between 92%-93%.
So, the high efficiency means the charger can be smaller.
This is PI’s ClampZero chip. Model is CPZ1062M.
It can form the ACF architecture with the master control chip.
After the current is stepped down, it must be rectified again.
The synchronous rectifier chip is integrated into the PI’s master control chip.
The synchronous rectification MOS tube should be behind this small PCB.
Take it down and let’s see.
YES, it comes from AOS.
Two solid capacitors are used for low-voltage filtering, connected in parallel.
The specifications for both are 25V 470μF.
After rectification and filtering,
the current can be used to charge. If it’s a single-port charger,
It can be directly matched with the protocol chip to charge.
But here is the dual-port charger. So we need secondary step-down circuit.
To remove those two secondary step-down circuits, They have the same layout and consists of a buck chip
with two MOS tube and an inductor.
The buck chip comes from ismartware SW3516H
and has built-in step-down controller.
It is used to control two MOS tubes
to achieve secondary step-down and can recognize different protocols.
So, it’s the first choice for multi-port fast-charging products.
Finally, Two outputs need to be coordinated
Only in this way, the power can be intelligently distributed.
So, there is an MCU on the back of the motherboard.
And the output strategy can be customized.
So, that’s all for the teardown of Anker PowerPort III 2-Port 65W Charger.
It adopts the brand-new design
of Anker PowerPort III series. And it also keeps the small size,
folding pins, dual USB-C and multi-protocol. Let the user experience move forward.
The charger adopts the power chip from PI. The efficiency of ACF architecture can reach 95%,
which is the guarantee for the small size. If you wanna buy this charger, it’ll need some
time to see it on amazon. Once there is an update, I’ll put it in the description of the video.
