Скачать или смотреть Can I Use a Charger With the Same Voltage but Different Amperage Rating?

⚜️ Chargers and power supplies come with different Voltage and Amperage ratings. But if you can't find the same, then choosing the right one is important. I'll look at a few of the parameters.

In Short:
For power supplies or chargers:
The voltage must match.
The amperage must match or exceed that required by the device.
The polarity of the connection must be correct.
The input line voltage (wall or “mains” power) must be supported, but is unrelated to compatibility with the device being charged or powered.
