USB chargers have been a staple of smaller electronic devices for years, from MP3 players to smartphones, but laptops have traditionally required bulkier power cables to get the job done. USB connections just didn't have the power to charge larger devices, like laptops. But USB-C changed that. If your laptop has a USB-C port, you can almost certainly charge it with it.
Some laptops come with USB-C ports that don't charge. This is most common on laptops that come with their own proprietary charger — although a number of laptops can be charged, either way, only the propriety charger tends to power up a laptop more quickly. Now, the charger used in a general laptop is 60W, 90W and 150W. We need to select the appropriate USB C laptop charger according to the actual situation.
