Company News >> How to tell the ac adapters quality
 The Shell

Pure PC material---High fireproof performance,high hardness,wear resistant,high temperature resistance,Welding effect high density, damage is reduced.

 

 


 

DC cable

 


Pure copper material---(below 65W adapters--0.5 full copper,above 65w adapter--0.75 full copper) Never reduce voltage.

 


 

Cooling


Using Standard Pure aluminum sheet for cooling---good heat-conducting property, make the adapter Low temperature, 

high quality MOS varactor

high cost meterial

 


 

Critical parts


Main Chip--Leadtrend/SLS/On Bright Technology(High efficiency,OVP,OCP,OTP)

MOS Varactor---full power, above 600V6A

Schottky--full power,full output power  

Capacitor---standard capacity,stable input,ac100-240v,worldwide use  transformer---standard, PQ model, full ouput power, low temperature, High efficiency

 


 

PCB


Half-wave panel---the circuit is not  breaked off easily,good fireproof performance, all components are SMT. Long service life and stable performance. Overrall efficiency more than 90%
