We have reviewed and teared down many high-output USB-C Power Delivery wall chargers over the last couple months. Today we will look at an Anker 18W USB-C charger that designed to charge smaller devices like smartphones.

I. Appearance

All white body design. This version is China plug and physically compatible with US plug. The prongs are foldable.

There is a round LED indicator. It will illuminated blue light when plugged in.

Specifications printed on the side.
PowerPort PD 1
Input: 100-240V~ 1.1A 50-60Hz
Output: 5V3A 9V2A

With ChargerLAB POWER-Z FL001 UPM, we got the same result from Power Delivery PDOs(Power Data Struectures) and it’s Power Delivery 2.0 protocol.

II. Teardown

We open the charger from the front panel. The panel is clipped into the body, unlike the ultrasonic welding we usually see in this type of product.

The transparent plastic for the LED indicator.

We open the other side of the body. Now we can see the main PCB.

The USB-C socket is welded on a small daughter board. There is also a USB-C controller. Two polymer capacitors next to the daughter board.

The remove the PCB from the shell. White thermal glues between components can be seen on the input side of the circuits.

Three electrolytic capacitors from Acon. Two larger ones are 400V 15μF. The smaller one is 50V 10μF for secondary filtering.

Close-up of USB-C socket and LED indicator. Again, white glues where used to help with thermals.

From the side of PCB, there is a slow-blow fuse, a common mode inductor and a Class-Y capacitor.

3.15A 250V slow-blow fuse to protect device from voltage spike.

Close-up of the USB-C daughter board. In additional the the controller, there is also a MOS for output.

The controller is from Cypress, model CYPD3175. It’s also certified for PD 3.0, although this Anker charger is only labeled as PD 2.0.

The output MOS. B09 P03 EKE1334.

The LED indicator is secured on another daughter board. Black foam is used to prevent light leaks.

Secondary filtering capacitor, 16V 470μF.

The back of the PCB.

Rectifier bridge for input. FT15SM.

PI Power IC INN3265C. It also integrated the features of switch and secondary rectification controller.

AON 4262 MOS.

All the components of the charger.

This wall charger is very well made. The highly integrated PI controller reduce the number of additional components required for the system, so the PCB looks much cleaner and it made such a compact design possible. The 18W output is exactly what you need to fast charge most current smartphones that support Power Delivery protocol.


  1. Has anybody verified that this actually an authentic Anker charger?

    I own at least a dozen recent model Anker chargers (USB A and C) and have never seen one that lacks holes on the fold-out prongs. I don’t have this particular model to compare to, but the casing finishes and the logo seem off too, especially when compared against the stock images from Anker’s website: https://www.anker.com/products/variant/anker-18w-power-delivery-usb-c-charger/A2019121

    • This model is for Chinese market. The main difference between China and US two prongs plug is there are holes on the latter one. Google “China Plug”, you will understand.

      Anker send us this unit for review, so this has to be authentic.
      The products we review and teardown on this website are often from different market, sometimes we even have prototype or engineering samples, so they may slightly vary from the one you get from retail.

      We will have teardown on fake Apple chargers in the future, so you can see the how terrible a “real fake” product can be.
