With the development of science and technology, everyone will use a series of electronic products such as mobile phones and notebooks, which need to be recharged. The problem is, the output voltage of the power adapter is the same but the current is different. Can this be used? For this problem, the basic principle is that the high current SMPS adapter can replace the low current output SMPS adapter. Some people may often walk into some misconceptions that excessive current will damage the equipment because they think the current is too large. However, in fact, this understanding is incorrect. In fact, the output of current depends on the load when the voltage is the same, that is, the normal working condition of electronic equipment. When our equipment operates at high load, the current will be larger, while the current will be smaller when the equipment is in standby. The switching power supply adapter with large current output has enough current, which will not cause overheating or low output voltage after replacing the small current switching power supply. On the contrary, there will be a considerable risk to replace the large current with small current.
However, some cases are OK. For example, some people use a 56W switching power supply instead of a 72W switching power supply. The reason is that there is a certain margin in the design of the common switching power supply adapter, and the load power is less than the power of the power supply. Therefore, this replacement is feasible in the general market. However, it is recommended that you use a switching power supply adapter with the same matching power, And now there are more and more regular manufacturers of switching power adapters. If your switching power adapter is damaged, you can buy matching products in many places. Of course, you must choose a regular manufacturer when purchasing.
