Anker, known as America’s Leading USB Charging Brand, just released a new power bank with not 1, or 2, but 5 USB-C ports! Therefore, we had to get our hands on it and have a look inside.
Anker’s classic packaging.
1.jpeg
The power port comes with a cable and a cable belt.
2.jpeg
The front and back of the power bank is a simple design.
3.jpeg
4.jpeg
An blue PD port is embedded in an aluminium plate with and is equipped with four power IQ USB ports.
5.jpeg
6.jpeg
Built with an universal power plug to be the most versatile power bank.  
7.jpeg
A rectangular power port with rounded corners.
8.jpeg
The top cover is being held by an ultrasonic welding, which is easy to open.
9.jpeg
The front and back of the power circuit.
10.jpeg
11.jpeg
The main voltage protection circuits and EMI circuits.
12.jpeg
There are two independent circuits for the power supply; both are 400V68.
13.jpeg
2 transformers.
14.jpeg
There are two reflective circuits and two anti-interference parallel capacitor plates.
15.jpeg
16.jpeg
USB Type-C output consists two electrolytic capacitors filter; both are Acon 25V680 microfarads.
17.jpeg
USB interface output filter consists of 2 solid capacitors, 6.3V1000 microfarads.
18.jpeg
4 USB sockets and the magnetic connector.
19.jpeg
After disassembling the tube, you can see 2 primary PWM MOS and 2 USB synchronous rectifier controllers.
20.jpeg
A small aluminium plate is placed on top of the large cooling plate to dissipate the heat further.
21.jpeg
The primary MOS is from Jilin Sino-Microelectronics JCS7N65FB.
22.jpeg
A Taiwan Huang Yang GBJ410 is used as a bridge to link two primary circuits.
23.jpeg
There are 2 secondary PMWs on both sides.
24.jpeg
Smart identification USB charger ports cellwise-semi CW3002F.
25.jpeg
PD Output Controller, Weltrend WT6630P.
26.jpeg
There are two secondary synchronous rectifier controllers and siyin MPS MP6901.
27.jpeg
There is PD output synchronous rectification MOS, NCE Power Semiconductor NCE01H10.
28.jpeg
29.jpeg
The front and the back of USB charger port protection board.
30.jpeg
31.jpeg
An output protection microcontroller LGT8P22A.
32.jpeg
33.jpeg
The front and back of the USB Type-C daughterboard.
34.jpeg
35.jpeg
The USB Type-C Output Protection MOS and the NCE Power Semiconductor NCE30P15S.
36.jpeg
37.jpeg
Using the POWER-Z to examine the PD mode of the USB-type C interface, it shows that the maximum current list supported by the PD mode is consistent with the details provided.
38.jpeg
The POWER-Z shows that the  USB-type C doesn’t support fast charging.
