USB has become more than a way of connecting devices to a computer with plug and play ease and high performance. It has also become the method of choice to power and charge a range of battery-powered devices from headsets to controllers to phones and tablets. Some of those phones and tablets have adopted proprietary mechanisms to draw more power than USB 2.0 was designed to allow - which has caused confusion about charging. That is being solved by the Battery Charging (BC 1.2) Standard - when both the device and the hub/charger is BC Standard compliant, it can charge at a faster rate (up to 1.5A) in a standard way. The Plugable USB2-HUB4BC is among the first of USB 2.0 hubs that does everything existing USB hubs do, plus has support for the Battery Charging Standard (BC 1.2). So it’s a no-compromise solution for both gaining extra USB ports, and for charging the newer generation of BC Standard compliant devices.USB Charging Battery charging over USB has become a standard practice but the actual charging behavior of different devices is often unpredictable and sometimes disappointing. The devices themselves decide how much current to draw and manufacturers haven’t settled on a single standard. We constantly test our products with as many different devices as possible and publish the results so it’s easy to determine the charging behavior to expect from your device on each of our USB products. These are the results for the devices we’ve tested on this charger so far.
