Understanding USB Devices

Technology manufacturers understand that making device-specific chargers is unsustainable and their solution has been to create more USB-chargeable products. Thanks to USB connectors, people no longer have to carry chargers everywhere they go. Smartphone owners can plug their device into a friend’s computer, or any product that has a USB port.

Within the USB network, there is always a host and a device. If the user plugs a phone into a laptop, the laptop is the host and the phone is the device. The host always delivers power to the device, but data can flow in both directions. When a smartphone is plugged into a laptop, the phone can send photos to the computer, but the computer can also send data – like music or apps – to the phone. Whether or not information can be transferred depends on the port. A standard downstream port — the type found on most laptops — delivers power and allows for an exchange of data, but a dedicated charging port only allows for charging. An AC wall plug with a USB port is an example of the latter.

Some ports deliver power faster than others. Many people report that their smartphone charges much quicker when it’s plugged into a laptop, than when it is plugged into a wall charger. The difference in charging speeds is due to the fact that not all ports are created equal. In fact, there are three main USB port types commonly found in devices. USB 1.0 and 2.0 sockets have four pins that carry a 5-volt power supply. USB 3.0 sockets have an additional 5 pins, and can deliver nearly twice as much power. The emergence of the stronger USB 3.0 has caused some people to worry about overpowering their devices. Smartphone owners who received a USB 1.0 or 2.0 wall charger are concerned that by plugging their device into a 3.0 port, they will cause an over surge. But you can plug any USB device and any USB cable into any USB port, without an issue.
