The Anker Nano 20W PD charger can be described as a mini. It integrates 20W power into the ultra-small body. Compared with Apple's original 5W charger, the power density is 4 times that of it, taking into account the charging speed and charging of mobile phones. Small size, easy to use.

The USB-C port supports Apple 2.4A, QC2.0, QC3.0, and PD3.0 protocols, and has two sets of voltage levels of 5V3A and 9V2.22A. This charger uses a switching power supply with a wide range of output and a secondary protocol chip Typical architecture for controlling the output voltage.

The AC-DC part of the charger is composed of PI highly integrated main control chip INN3265C and UBIQ secondary synchronous rectification MOS, and uses Cypress USB PD fast charging protocol chip CYPD3175 to control the output voltage.

Anker uses Apple's 18W charger from the same factory Chip, in addition, the charger adopts a structure design similar to "sandwich biscuits".

The components such as electrolytic capacitors and transformers are arranged between the input and output boards. The components are fixed with glue, which not only effectively compresses the volume of the charger, but also makes the interior more stable.

Capacitors and transformers are protected with insulating tubes and wrapped with tape. The ultra-small body of Anker Nano 20W PD charger is created by the combination of highly integrated fast charging solution and ingenious design.
