Samsung Galaxy Note 7 explosion caused a comprehensive recovery, so that the public once again concerned about the issue of mobile phone. Phone charging with USB charger and power cord cause fire even the battery explosion of the news, it is not uncommon. What is the most secure mobile phone point, what is the correct charging attitude?
First, Avoid calling and filling When the phone through the instantaneous current will be larger, the battery frequent charge and discharge, leading to long-term overload of lithium batteries, heat naturally increased. So we should be unplugged when the phone should be unplugged, even if the unfortunate explosion, it will not wounded pro.In addition, to develop the habit of carrying the right hand with the phone, because the left hand closer to the heart than the right hand, leakage when the left hand will increase the risk of casualties.
Second, Reduce computer charging,I believe we have tried to connect the phone to the computer charging. But in fact, even more harm than good, mobile phone standby but the computer continues to operate, the latter from time to time to read and write hard drives and USB port, this will USB power output caused by great fluctuations and reduce battery life.In addition, the USB charger specification under the fixed voltage of 5V, current 500mA, but with the mobile phone battery capacity increases, many phone usb charger current rating of 2,000mA or even more than 4,000mA, so the computer USB charging, charging time not only significantly extended, Computer USB interface will be a long time in the overload state, increased heat, the computer and mobile phone components damage.
Third, Avoid alternating use.Do not use the computer to charge.Basically, the use of high-current output of the USB charger and power cord for charging the electronic device, the problem is not large, but if the device needs more than the usb charger to provide and power cord, for example, to 1,000mA input phone,but connected to only 300 to 500mA USB charger and power cord , Then the charger will be overworked, the phone's internal protection lines, more opportunities for the current reading does not match the automatic cut off the power supply, resulting in mobile phone charge to 99% stop or broken.So it is important to choose a suitable USB charger and power cord for your phone.
The quality of the usb charger and power cord will affect the safety, if the metal part of the exposed, the current is not up to the phone has been leakage, the user contact at the same time under the foot, it will form a complete circuit led to electric shock, so if the wire is damaged, it must be replaced immediately.In addition, in the USB pin definition, DC-DC converter is responsible for power supply and data transmission purposes, if D + and D- short circuit,the phone will be determined to get AC mode Fast fork. As for how to choose a good usb charger and power cord, because most of the cable is not marked specifications, in addition to the price, the easiest way is to use rough to identify the thicker power cord wrapped in wire covered with insulating rubber and ground isolation network of high chances, Security is more secure!As for how to choose a good USB charger and power cord, because most of the wire is not marked specifications, in addition to the price, the easiest way is to user though to identify the thicker lines wrapped in wire covered with insulating rubber and ground isolation network of high chances, Security is more secure!
