Anker's AC adapter is disassembled into pieces, and even with a cobblestone mixed AC adapter, the 'good product' is like this
It is difficult to estimate the quality of AC adapters that charge electronic devices from the appearance, and in order to distinguish between good and inferior products, it is necessary to disassemble and check the contents. It is reported that by disassembling the AC adapter 'PowerPort PD 1 ' that can charge 18W quickly even in a compact size, we were able to confirm the popularity of Anker by offering high quality products at a modest price.
Anker PowerPort PD 1 USB-C Wall Charger Teardown | ChargerLAB
Ben, who has made numerous product disassembly reports on the Charger Lab, disassembled the 'PowerPort PD 1' with a simple design of a white body and a blue LED indicator.
When measured with a tester before disassembly, it was confirmed that it can be charged correctly with 18W of 9.00V × 2.0A and 'USB PD 2.0' standard.
When the front panel is removed, the panel is fixed with claws instead of ultrasonic welding, which is often used in this type of product.

If you remove the connector on the back and the cover on the side, the inside will be exposed.
Equipped with 400V 15μF and 50V 10μF ACON electrolytic capacitors.
A Type-C USB port and a daughter board for LED indicators are mounted around the transformer that occupies most of the interior.
The blue Y capacitor is firmly fixed with a hot bond.

Type-C daughter board
The controller is Cypress's 'CYPD3175'. CYPD3175 itself has been certified as USB PD3.0, but PowerPort PD 1 is treated as USB PD2.0 certification.

By using an advanced PI controller to reduce the number of parts, we have realized a compact design despite being able to quickly charge a smartphone with an output of 18 W, 'PowerPort PD 1 is very well made.' Ben appreciates it.
