Choosing the Right USB Charger

A USB charger transfers an amount of electrical current from a power supply or battery to a device that requires it to function. These devices are commonly mobile phones, computers and other portable devices. USB technology, originally developed for computer peripherals like mice and keyboards, now serves as the primary method of supplying energy to smartphones, tablets and other mobile devices. Choosing the right charger helps ensure that your device charges quickly and safely.

When choosing a usb charger, consider the maximum current the device needs to charge at its peak performance. The maximum current is typically specified by the manufacturer of the device. You can determine the correct maximum current for your device by checking the user manual or contacting the manufacturer. The maximum current may also vary between different ports on a usb charger. For example, a four port charger may have a higher total current than a two port charger.

Choosing the right usb charger for your devices ensures that you get the most out of your investment. Choosing the incorrect USB charger could damage your device and lead to overheating or fire. This is especially true for older USB 2.0 chargers that don't support USB PD (USB Power Delivery) technology.

USB charging works by creating a low voltage output from AC power. This is converted to a safe level by an internal circuit. The smart chips in the charger then communicate with each USB port, for example a tablet, to determine what its maximum current level is. The port then begins to charge the device, delivering its optimum current.

One of the reasons that some USB chargers are slower than others is because they share their current among multiple connected loads. If a single port is used to charge a laptop and two mobile phones, the overall charging rate will be reduced because the charger can't deliver enough current to all devices simultaneously.

The USB 1.1 specification was designed to address these issues. In addition to adding more uniformity, it supports USB PD (USB Power Delivery) protocol, which allows for a much higher amount of power to be delivered over long distances. This is necessary because most mobile devices require the greatest amount of power when they are docked, and this can be difficult to provide over long distances with standard USB connectors.

When shopping for a usb charger, look for USB-IF certification and a Connected Equipment Warranty (CEW). This will ensure that your charger meets the standards set by the Universal Serial Bus Implementers Forum to help reduce risk of overheating or fire. In addition, the CEW label provides assurance that your charger is compatible with your smartphone, tablet or other device. It is important to check your manufacturer's website for the latest compatibility information. The GE 2 USB | 1 AC Outlet In-Wall Charging Receptacle is an excellent option for your home or office. It provides the convenience of a dual outlet and two USB charging ports that eliminate clutter on desks, nightstands or other surfaces.
