3.Mobile phone charger

 

Mobile phone charger also known as: mobile power supply, charging treasure, are actually composed of a stable power supply (mainly a stabilized power supply, providing stable working voltage and sufficient current) plus necessary constant current, voltage limiting, time limit and other control circuits . This charger comes with the phone, and the original quality is good, so the charging current design is large, and the charging time is short.

 

Type of  phone charger

 

For the effect of direct charging, it also depends on the mobile phone. Because the charging control circuit is on the mobile phone, its cut-off voltage has a certain dispersion. I actually measured the same batch of mobile phones of the same model between 4.09V and 4.21V. That is to say, if 4.09V is cut off and not fully charged, it is not the optimal capacity, and it may be fuller when it is charged for a period of time. But do n’t forget that even mobile phones with trickle charging, just like the difference between the charging voltages of 4.09 and 4.21, the trickle charging current of mobile phones has a certain dispersion. If the charging current is large, it will become charging. Now, for 10 hours, the battery is also damaged. I have encountered many battery charging failures on mobile phones. There are also original batteries and branded batteries. If the battery is charged, causing leakage, etc., and the phone may be damaged, it is recommended that if you really want to recharge, you should control it within 2 hours and not exceed 8 hours.
