Please tell me how to buy a laptop adapter separately

pu1. It's the voltage. You don't have to pay much attention to your laptop. If you choose a high current, you can charge it quickly, but you may not be able to use the battery for a long time. The charge might be unstable. If possible, I recommend buying the same current value (A)

OK

pu2. First of all, voltage (V) and current (A) are important. In the case of Adapta, it's Free Volta these days, so it's probably right. It's just that the current is important, and you have to choose one that's more than the current value

OK

pu3. There's something important, but it might not fit in the terminal. Each laptop has a different size. We need to check that out, too
