There are generally three items on the label of the power adapter that need to be paid attention to. The following power adapter manufacturers will introduce you in detail:
1. The model of the adapter. For example, the model of this adapter is XVE-120100. It tells us a few information about its manufacturer, wattage, etc. The beginning of XVE is generally ##Company code, 120100 means that the adapter is 12W, 050200 is 10W.
2. The INPUT of the adapter is generally 100-240V~50-60Hz in China, which means that the adapter can work normally under the voltage of 100V-240V.
3. OUTPUT of the adapter. Two numbers can quickly calculate the wattage of the adapter. For example, for this adapter, voltage 12V*current 1A=12W (power), indicating that the power supply is a 12W adapter.
The power adapter of most notebook computers can be suitable for 100～240V alternating current (50/60Hz). Basically, most notebook computers have an external power supply, and use a power cord to connect to the host, which can reduce the size and weight of the host. Only a few models have the power supply built in the host.
