Teach you to identify the quality of the charger

The so-called fast universal charge on the market, voltage 4~6V, current 0~700MA. High voltage and high current charging speed is of course fast, but too high current can cause the battery to drum, shorten the service life, and high current will generate large heat. If the temperature is too high, the battery will explode. This is the most serious safety hazard. In the first two years of the summer, there were several news that the temperature of the mobile phone battery exploded and injured people because of the high temperature. Everyone is interested to look for it. The safety issue is really not a joke. From this it can be concluded that the charger is not charging as fast as possible.

Since the news that the battery temperature is too high and exploded, many manufacturers have made changes in the power output, and increased the voltage limiting current limiting resistor, so that the voltage and current are controlled, the temperature will not be high, but the voltage is too low. The battery can't be fully charged. If it is charged once, it will be out of power for a long time, or the current high-capacity battery will be charged for 1-2 days. After a long time, the battery capacity will decrease, which will affect the service life. It is recommended to use chargers from large brand manufacturers, such as Hailutong, and Feifei. Recently, a new universal charger, Boao, and Bomeihui brand has appeared on the market. It is said that the manufacturer is Shenzhen Bonis Technology and the factory is in Putian. Boao's three-lamp charger and colorful charger I bought and tested it, the electrical performance is very good, in the standard range, and the flying hair retreat, Hailutong and other big brands do not distinguish. More cattle is to make a drop, 1 meter 5 times, completely OK, the shell is a little broken, 2 meters 5 times or no big problem. From the 4th floor, the shells are rotten, basically in the state of streaking. After picking up and powering up, there is no problem in electrical performance. Look carefully at the electronic parts and solder joints. The materials are solid. Ordinary universal versatile still says that it is falling, and it will fall off if it falls off the solder joint a little, and the whole machine will not work. The only regret is that Boao's colorful appearance is still old-fashioned egg-shaped, not very beautiful, and I look forward to a more beautiful appearance in the future. The price is also cheaper than the flying hair, Hailutong is cheaper, the price is very high, it is recommended to try it.
