There are many models of power adapters, how people should choose a power adapter, replacement there are several principles, on the line.


1. Divided into clear use
Want to sell a home and office use to buy a home, want to use the car, buy a car, want to use the aircraft on the basis of the car with an aircraft head can be. Home, car, airplane, both want to take into account, buy a two-in-one, or three in one. However, if you do not want more weight in the computer bag, you can put one at home, put one in the car, put one in the office, so you do not have to bring to, plugged in and out, more convenient, but also to the people around you.


2. Clearly distinguish between voltage, current
Look at the original laptop is which brand, the original charger written on the back of the label how much V, how much A, such as the original charger is 18.5V 3.5A That means you must buy the output of 18.5V. But if it is 18.5V Z good not to, although it can be charged, special circumstances emergency can be charged, over time will cause damage to the battery and laptop. That means the voltage should be accurate.




3. The same plug
Charger connector is probably round or square, or multi-hole, as long as they clearly understand in their own mind, they will not buy the wrong, or even be cheated. The polarity marked on your laptop symbol is inside positive and outside negative, if the symbol is different from the one marked on the laptop, it will definitely not work.


4. The rated output current of the power adapter can not be less than the rated input current of the computer.
Your computer is marked on the Z large input current is 3.36A, then you should buy a power adapter when the output current is greater than or equal to 3.36A, the greater the better, but the greater the output current means the greater the rated power, too large then too wasteful, and very bulky, generally slightly greater than the line, leaving some margin.
