I bought a fake Samsung battery charger on Taobao. Will it hurt the battery? And it can only be charged to %96.

Shanzhai charger can't guarantee the stability of current, and the materials and current used in Shanzhai mobile phone charger on the market are different from the original charger. Due to voltage and capacitance, it is likely to cause the explosion of the mobile phone. Non-original charger, lack of protection circuit, can not ensure the stability of current when charging, easy to burn out the battery, shorten the service life, and even have the danger of explosion. The original charger is equipped with a transformer, which can automatically adjust even if the voltage is unstable, which is safer. Be cautious when buying, don't pursue appearance, function and price excessively, and choose a legal distribution agency that values reputation and service.
