What types of chargers are there?丨MSH
The best dock type chargers are easy to carry and use, and have always been popular with users. However, there are many brands of dock type chargers on the market, and the quality is uneven, so you should pay more attention when purchasing. The following items should be paid attention to when purchasing: (1) Weight. Generally speaking, the heavier the charger, the more electronic components the charger uses, and to a certain extent, the better the quality of the charger. This method is the most intuitive and more effective. When purchasing, it is best to take a few more chargers of different brands and models, and weigh them with your hands. Once they are compared, the pros and cons are easy to compare. (2) Function. The function of the socket charger mainly depends on the IC (smart chip) it uses. At present, the IC has developed to the third generation. After the improvement of the first two generations of ICs, the functions of the socket chargers manufactured with the third-generation ICs are relatively complete. However, due to the fierce market competition, many manufacturers often use the second-generation ICs with lower cost to manufacture the socket-type chargers and impersonate them. Products manufactured by third-generation ICs are sold. Therefore, first of all, it is necessary to understand the difference between the functions of the three generations of ICs before and after. If it is a cradle charger using the second-generation IC, you need to plug the cradle charger into the socket every time you charge, and wait until the self-test is completed before placing the battery on the charger's socket for charging, otherwise it will be charged. If there is an error that the charger is inaccurate in judging the battery level, it cannot be charged normally. Therefore, when purchasing, it is very intuitive to use a battery with insufficient power to check that the IC used in the cradle charger to be purchased belongs to which generation of products. (3) Pins. Dock chargers are generally divided into two-phase fixed pins and two-phase/three-phase variable pins. When purchasing, it is best to choose two-phase/three-phase variable pins, which will be much more convenient in future use. In addition, you should try to pull the pins of the base charger when purchasing. If it is easy to pull out the pins, do not buy such products. (4) heat generation. When the cradle charger is working, the internal transformer will generate a certain amount of heat. Generally speaking, the better the quality of the transformer, the lower the heat generated. As long as the temperature generated by the charger during the working process is lower than 30 °C, that is, it is slightly hot when touched by hand and not hot, it can be regarded as meeting the standard. Therefore, when purchasing, you should choose several different cradle chargers, let them all work for a few minutes, and then feel the heat. You should choose a product with a relatively low temperature. (5) Production process and raw materials. If conditions permit, you can also disassemble the base charger and directly check its circuit board manufacturing process, spare parts quality and welding process for quality identification.
In addition, the solder joints on the circuit boards of general high-quality chargers are uniform in size, and there will not be a large piece of solder attached to the soldering places, and the components such as transformers, capacitors, and triodes used are relatively large and large. The quality of the components is good, the life of the base charger is not only long, but also the performance is more stable.
