There are many models of power adapters. How do you choose a power adapter? There are several principles for replacement.
1. The voltage is the same or similar. The nominal input voltage on your computer is 16V, and the rated output voltage of the following adapter is 20V, which is quite different and cannot be replaced in this way, which may damage the computer.
2. The plugs have the same polarity. The polarity of the symbol on your notebook is negative inside and outside. I can’t really see the polarity of the label on the adapter. You can see if the symbol is not the same as the one on the notebook.
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, then you should buy the output current greater than or equal to 3.36A when you purchase the power adapter, the bigger the better, but the larger the output current, the higher the rated power, too big. Waste, and very cumbersome, generally slightly larger than the line, leaving some margin.
