An increasing number of devices rely on USB chargers (Universal Serial Bus) to draw power. Cell phones, tablets and game console controllers all connect and charge via USB connections. While it is likely that you have a collection of cables and USB plugs in a drawer, grabbing the closest charger might not be your best option. A group of electronics manufacturers introduced the technology in a bid to replace standards, including PS/2, Parallel and DB9 Serial connections. Today, there are various USB variants in use, which means that you first need to ensure that you choose the right standard from a selection that includes USB-A, USB-B, USB Type-C™, and both micro and mini versions. Furthermore, some USB chargers offer faster charging, thanks to a higher voltage or thicker lead, and some act as a hub, providing charging and connection for multiple devices.
Several factors determine how quickly a device will charge. Ensure that your USB wall charger delivers enough amps to charge at the fastest rate possible. iPhones and iPads® need 1 amp and 2.4 amps respectively, while Android phones use up to 1.6 amps. If you charge multiple devices through a single charger, add the amps for each device, then pick USB adapters that offer over and above that total. For example, if you charge two Android devices, any charger rated above 3.2 amps will provide the fastest charging times possible. Consider a charger that gives you flexibility of use, as well. For example, portable AC power cords for laptops are fitting for frequent travelers, such as students or busy employees.
Other factors determine charge time. High-voltage chargers pass more electricity through to connected batteries, which reduces total charge time. The standard for most devices is 5 volts, but higher voltage models are available. Choose a cable that matches your length requirements. Short cables of 1ft or 2ft are suitable for desktop use. USB car chargers are 2ft to 3ft in length, and 6ft-long wires offer optimal use on nightstands and in hard-to-reach areas. Even the thickness of the USB charger cable matters, especially in wires that are longer than 6ft. Thick USB cables charge faster so users can save time and enjoy a full battery.
The proliferation of smartphones and tablets indicates that a typical person might need to charge three or four devices at once, due to current usage patterns. Using a separate charger for each device means taking up valuable outlet space. With a USB lead, you can connect to a desktop or laptop and draw power via your computer power adapter cable. USB ports can only pass 500 milliamps of power at a time, and wall outlets can pass 2 Amps. With a multi-port charging station, you can charge four or more devices using a single USB wall charger, and enjoy faster charge times.
