The Shell


Others bad quality

ABS material---NON-fireproof,poor hardness,Easy to be weared and scratched,cheap,low temperature resistance,easy to be damaged

 

our high quality

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


 

DC cable


Others bad quality

not pure copper material--- easy to be oxidizable, always reduce voltage,high heat,easy to be burned.

 

our high quality

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


 

Cooling


Others bad quality

using sheet metal for cooling---poor heat-conducting  property;

bad quality MOS varactor---easy to blow up. make many problems. 

the material is cheaper quadruple than ours.

 

our high quality

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

high quality MOS varactor

high cost meterial

 

our original quality

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

high quality MOS varactor,      

high cost meterial

with Conductive epoxy---(1.fixing the components; 2.helping the components cooling; 3.the components are not easy to damage when drop off,high stability ;4.coupled with Shielding aluminum shell,Electromagnetic interference shielding)


 

Critical parts


Others bad quality

No filter,only X capacitor---NON Conduction-interference,high radiation, low electric capacity, poor pressure-resistant , 

used MOS varactor---500V5A,easy to blow up.
schottky---using small power to replace the big power(below 25W) 

transformer---bad quality magnetic core,high heat, non full power, small output capacity, poor filtering,high interference 

Main Chip---old design 3842 technology

 

Our high quality

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

 

Our original quality

Main Chip---Leadtrend/SLS/On Bright Technology(High efficiency,OVP,OCP,OTP,Constant voltage,Constant current, SCP,self-locking function--when the voltage rise Accidently,it will be locked by itself,then the adapter no output,make sure the adapter not damage the device)
MOS Varactor---FUJI(Japan) 

Schottky--ST(USA) 

Capacitor---High frequency low resistance,the whole adapter full output power,high efficiency,low power consumption.when the input voltage higher 300V,the power will be cut off automatic.  

transformer---TDK(JAPAN),shielding function, small radiation,small electromagnetic interference , full ouput power, low temperature, High efficiency


 

PCB


Others bad quality

paperboard PCB---flammable, the circuit is breaked off easily,Overall Efficiency lower70%. Low efficiency,non pro-environment ,no OCP OVP OTP function.

 

Our high quality

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%
