This disassembly is a single USB output QC3 from Shenzhen xinsibao Technology Co., Ltd 0 power adapter    
Single USB output socket. The logo below the socket indicates that this power supply supports QC3 0 fast charge.    
Foldable mains socket, easy to carry out  
   
From the identification of the power adapter, the maximum output power of this power supply is 18W    
Like most folding plug power supplies, the mains part uses power cord connection to increase reliability      
The front and back sides of the Power PCB are compact, neatly arranged, and the solder joints are full of luster.    
Protection circuit and EMI circuit of mains power input part.  
   
The primary side main capacitor uses three 400V 15 micro methods in parallel, and the brand is from ACON.    
The blue JEC y capacitor is mainly used to filter out high-frequency interference.  
   
The secondary side output filter uses a 16V 680 micro method solid-state capacitor    
Rectifier bridge model abs10.  
   
The power integrations inn2215k IC has a controller on the primary side and a power MOSFET on the primary side. The secondary side controller monitors the output voltage and current, feeds back the information to the primary according to the monitoring results, and carries out corresponding switching control, so as to achieve more accurate control of output voltage and current. It can provide a maximum output power of 22 W.      
Output terminal synchronous rectifier MOS, from new power, model ncep0114as.      
QC3. 0 intelligent identification IC, from eosmem, Taiwan Xiwei, model nt6008b.      
Use power-z to detect the mode supported by this power supply, which supports QC3 0 also supports QC2 0 agreement with apple.
