What’s in the box?
Black Plugable 10-Port USB Hub, 2.5A Power Adapter with 70″ power cord, 40″ USB A to mini-B cable for connecting to PC.
Can the hub charge iPods/iPads and other smartphones?
It does not have special support for Apple proprietary charging, beyond the 500mA rate which is standard for USB 2.0. This means iPads will only trickle charge, and only when the iPad is turned off (if turned on, the iPad will report “Not Charging”). For iPods, iPhones, and other devices, it will charge only at the standard 500mA rate.
Can devices be charged without a PC attached (or when the PC is off)?
No. USB 2.0 requires device-host negotiation, before the full 500mA can be supplied. Without negotiation, the hub can and does supply some current (< 100mA), but it is not enough to charge most high-power devices.
Can the hub support 10 devices which use or charge at the full 500mA rate?
No. The hub comes with a 2.5 Amp AC adapter, which assumes a typical mix of high and low power USB devices will be used, consuming 250mA average. So for scenarios where the devices are known to need or use the maximum 500mA each (for example, wanting a charging station for 10 iPods), only 5 devices can be charged at the maximum rate.
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). This takes power from one USB port and shares it with all the devices that are connected. With many devices attached, this will likely not be enough for all attached devices, causing the first few devices to work and the rest of the devices to be disconnected from the host OS (and unfortunately, which ones will fail are unpredictable based on order of device start up). 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?
There are two versions of the hub available:
- On eusbhubs, they sell the USB hub with a power adapter with swappable prongs for UK- or EU-style electrical outlets.
In both cases, the switching power adapter with our 10 port hub supports inputs of 100-240V ~ 50/60 Hz 0.5A. Output to the hub is 5V 2.5A through a Center Positive coaxial barrel connector with OD-3.5mm and ID-1.3mm. You will not need a power converter as long as the input is within the given ranges.
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 firstname.lastname@example.org 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.
