If your laptop charging cord is lost, damaged or not functioning as it used to, it’s time to get a replacement. Finding the right laptop charger for you begins with identifying the charging interface you need. The charging interface is the plug that fits into the charging port of your computer. Different brands and models will use different interfaces.
For the greatest versatility, you can choose a universal laptop charger, which includes multiple interface connections in one package. However, “universal” can be a misnomer because there are some computers, like MacBooks and Microsoft Surface laptops, that use interfaces not always included in the universal sets. For a Microsoft laptop charger or an Apple MacBook charger, be sure to look for those brands specifically when shopping.
A laptop charger also works in tandem with an adapter. The adapter is the hub on the power chord that converts the voltage that is coming out of the socket into what is suitable for the laptop. Adapters may be sold with a charger, or separately.
