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 ChargingBattery 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.
For hubs, "Hosted" means the hub is attached to a host computer that is powered on. "Unhosted" means just the opposite, that the hub isn't attached to a host computer, or that the host computer is turned off. This doesn't apply to stand-alone chargers that only plug in to a wall outlet.
The "Estimated Charging Time" column is the minimum amount of time that the device would take to charge if it was fully drained. This is just an estimate! We provided this to give a general idea of the expected charge time. If this column is blank for a device, that means that the device indicated that it wasn't charging. In this case, even if the device is drawing power, it will likely either "tread water" keeping the battery at a constant level, or slowly lose ground.
Is the AC power adapter required?
When the hub’s power adapter is not connected, the hub is capable of running purely from bus power (from the host PC). When a hub reports itself as bus powered to the OS, the OS looks in the USB descriptors for every attached device, sees how much power the device reports that it needs reserved for it, and pops up a error (and possibly disables devices) if the total amount of power requested exceeds what a bus-powered hub in theory can count on pulling, which is 500mA for USB 2.0/1.1. We recommend always using the power adapter for best results.
Does the power supply switch for different regions or is it tied to US voltage and frequency?
The switching power adapter with our 4 port hub supports inputs of 100-240V ~ 50/60 Hz 0.5A. Output is 5V 2.5A and comes with a US standard plug. You will not need a power converter as long as the input is within the given ranges. You might need a plug adapter for different regions which is not included.
What does the blue light mean?
The blue light indicates that the hub is receiving power. To test the AC power supply, connect the hub to only the AC adapter and nothing else. The blue light should be on, if it’s not there’s something wrong — contact us at email@example.com for assistance.
Is there a way to turn off the blue LED bar on the hub?
No, the LED indicates that the device is powered.
