XiaoMi’s 65W charger adapter looks like their 45W version, but just slightly larger.

The end of the cable where it connects to the body of the charger is reinforced to ensure durability. Next to it is a XiaoMi logo as you can see.

The cable is Type-C.

Manufactured by Tianmi, the charger supports output voltages of 5V, 9V,12V,15V,20V; with a maximum output power of 65W.

A comparison of the size differences between 45W and 65W power adapter.

The case of the adapter is assembled with ultrasonic welding. After opening the case, you can see there’s a layer of glue between the circuit board and case. However, after removing the glue, the circuit board is still firmly in placed.

The back cover of the charger is double layered, held together by ultrasonic welding. 

There is a small hole next to the cable. We were abled to put pressure on this spot to take a part the case.

You can use a tiny screwdriver to push the case open.

The entire charger is protected and held together by a metal shield.

We removed the metal shield.

The front and the back of the circuit board feature a interesting layout for cooling.

The main power supply protection and EMI circuit.

The main circuit board is protected by a separate metal shield.  

The main capacitor’s brand is the Taiwan Jinshan ELITE 420V120 micro method.

The rectifier bridge and the main switch share one heat sink.

The transformer parameters.

The blue anti-interference capacitor.

The output filters two electrolytic capacitors in parallel

The Type-C cable is connected by the three-core.

The LITEON Guang Bao rectifier bridge KBP208GL 2A800V.

The Toshiba K3569 Main Switch.

LITEON Guang Bao Schottky rectifier diode G40120CTW.

We used the POWER-Z to test the fast charge mode, but it doesn’t seem to support all the mainstream fast charge modes.

For the ones that it did support with PD charging mode, we found that the results are pretty true to the specifications listed on the package.
