1. Separate the purpose
If you want to use it at home or in the office, just sell it and buy a home. If you want to use it in a car, buy a car. If you want to use it on a plane, you can use it with an airplane head on the basis of the car. NS. At home, in the car, in the airplane, if you want to take care of it, buy a two-in-one or three-in-one. But if you don’t want to have multiple weights in your computer bag, you can put one at home, one in the car, one in the office, so that you don’t need to bring it with you, plug it in and out, it’s more convenient, and it can be used by people around you. .
2, distinguish voltage and current
Look at which brand the original laptop is. The label on the back of the original charger says how much V and how much A. For example, the original charger is 18.5V 3.5A, which means you must buy a 18.5V output. But if it is 18.5V, it’s best not to. Although it can be charged, it can be charged under special circumstances. Over time, it will damage the battery and laptop. In other words, the voltage must be accurate.
3, the same plug
The connector of the charger is probably round or square, or porous, so that you can know it in your heart, so that you will not buy the wrong one or even be fooled. The polarity of the symbol on your notebook is positive and negative. If the symbol is different from the one on the notebook, it will definitely not work.
4. 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 must buy an output current greater than or equal to 3.36A. The larger the better, the larger the output current, the greater the rated power. It's wasteful and bulky, usually slightly larger than that, leave some margin.
