A power adapter is sometimes referred to as an AC power adapter or an AC adapter. All of these names are correct, except for the charger. The function of a charger is different from the function of a power adapter. We will discuss this further in this article.
If you see any of these names on the Internet or on the sales materials for the product you are considering, there is a 90% chance that these materials refer to a power adapter.
What are the precautions for using the adapter?
What is the replacement principle of the adapter?
What is the purpose of a power adapter?
First, the mismatched interface must not be plugged without professional knowledge, otherwise it will be dangerous.
Second, why do you need the same voltage? In principle, this is also the case - insufficient voltage, insufficient driving load, the battery cannot be charged normally, and the popular point is insufficient supply
Third, why do you need such a current configuration? It involves the principle of the circuit. The power supply has internal resistance. The greater the internal resistance, the greater the loss. Therefore, the manufacturer will determine the no-load according to the position size when producing this adapter. The output voltage is within a certain range, and the current threshold corresponding to the voltage threshold is the nominal current value we see. The larger the nominal current value, the better the load capacity of the adapter. Therefore, choosing an adapter with a slightly higher current will not only not damage the battery, but will make charging faster.
1. The voltage is the same or similar. The nominal input voltage of your computer is 16V, and the rated output voltage of the adapter below is 20V, which is quite different. If you cannot replace it in this way, it may damage the computer.
2. The polarities of the plugs are the same. The polarity marked on your notebook is positive inside and negative outside. I really can't see what polarity is marked on the picture of the adapter. If you look carefully, if the symbol is different from the one marked on the notebook, it will definitely not work.
3. The rated output current of the power adapter cannot be less than the rated input current of the computer. The maximum input current marked on your computer is 3.36A, so when you buy a power adapter, you should buy one with an output current greater than or equal to 3.36A. Wasteful, and very bulky, generally a little larger than that, leaving some margin.
A power adapter is used to convert AC voltage to a single DC voltage for a computer. It runs as an external battery for the computer, so the size of the computer does not need to be as large.
Computers use many different DC voltages. One is provided by the power adapter and another is provided by the computer's own internal circuitry. These combine to provide the computer with what it needs. The power adapter acts as a battery, providing a specific amount of energy and voltage to the particular computer it is plugged into.
