USB stands for Universal Serial Bus. It is a type of connection that is used to connect devices like computers, printers, and external hard drives. USB ports can also be used to charge devices. However, the amount of power that a USB port can provide is limited. This can be a problem if you are trying to charge a device that requires more power, such as a laptop.
There are a few things that you can do to boost USB power. One option is to use a powered USB hub. A powered USB hub is a device that has its own power supply. This allows it to provide more power to connected devices. Another option is to use a USB charger. A USB charger is a device that is designed to charge devices. It can provide more power than a USB port on a computer.
