Distinguish between good and bad

 

Why do shanzhai goods often have accidents? Shanzhai phone charger cost is low, the quality is no guarantee that material appearance, for example, the appearance of the authentic chargers plastic using the native plastic, high hardness, and fake goods to use recycled plastic, material price is only about half that of the former, and resistance is much less than the former In addition, fake goods also has the problem of serious cut corners

 

The material of the exterior work shell is very important

 

Mobile charger appearance of choose and buy must better, not have burrs, insert must be smooth, convenient metal contact to thick homogeneous elastic, the charger plug have difficulty will be very easy to damage Then there is the shell to resist flame retardant, not rigid flame retardant plastic, the charger will be hot baked soft and even fire

Cell phone charger shell must be resistant to flame retardancy

 

And there are a lot of shanzhai mobile phone charger, although the appearance and quality goods looks about the same, but the internal structure is different Due to churn out fake charger often occur between the conductive parts breakdown of the insulation is current problems, to produce fire accident getting an electric shock Not only that, but bad cell phone charger after the completion of the automatic power, not only damage the battery life, still exist explosion hazard
