New Design Wall Mount 12V 1A Universal Power Adapter

Power adapter, also known as external power supply, is a voltage conversion device for small portable electronic devices and electronic appliances. It is commonly used in small electronic products such as mobile phones, LCD displays, and laptops.

Can I use the same laptop with the same power supply voltage and different output currents. The basic principle is that a power supply with a large nominal current can replace a power supply with a small nominal current. Some people may think that a power supply with a large nominal current will burn out the notebook. In fact, how much current depends on the load at the same voltage. When the notebook is operating at a high load, the current is higher. When the notebook enters standby, the current is lower. A power supply with a large nominal current has sufficient current margin.
