Charge and Sync Almost Anything
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 huge range of portable battery-powered devices like cell phones, tablets, USB battery packs, handheld game consoles, e-readers, cameras, smartwatches, fitness trackers, bicycle lights, and many more. Some of those mobile devices have adopted proprietary mechanisms to draw more power than USB was originally designed to allow which has caused confusion about charging but is now being solved by the USB-IF (USB Implementers Forum) Battery Charging (BC) standard.
The Plugable USB 2.0 4-Port Hub (USB2-HUB4BC) does everything existing USB hubs do, plus has support for the Battery Charging standard. So it’s a no-compromise solution for both gaining extra USB ports, and for charging the newer generation of BC standard compliant devices. When a compliant device is attached it can charge at a faster rate (up to 1.5A vs 500mA of a standard port).
USB Battery Charging
Since the hub conforms to the USB Battery Charging specification, nearly any modern device will charge when connected. If the hub is connected to a host computer, you can also transfer photos or other files on the device to your computer.
Incompatible devices include early generation iPads and iPhones that don't use the Lightning connector, some older Android phones, and some of the larger Windows tablets. All of these devices require proprietary signaling and need a special charger.
USB 2.0 Connectivity
For basic USB connectivity, this hub works well with most devices. USB 2.0 has been the standard for device connections for quite a few years, so there are generally no surprises with a USB 2.0 hub.
Even USB 3.0 devices work on this hub because of backward compatibility. However, they will be limited to the USB 2.0 maximum of 480Mbps.
The hub body measures 2.5in x 1.5in x 0.75in, plus the external power adapter.
The power adapter is not required for basic, low current, non-charging USB connectivity (up to 100mA per port), but we recommend using it for most situations.
The hub pairs well with a Raspberry Pi because of its diminutive size. In the snake-eating-tail configuration, this hub can provide 3 extra ports, and simultaneously power the Pi.

USB Port Types
This is the standard USB connection that most computers offered prior to the introduction of USB Type-C (USB-C). Even after the introduction of USB Type-C, this is still quite common.
It can provide data transfer rates up to the USB 3.1 Gen 2 (10 gbps) specification depending on the host and device, but does not directly support video in the way that USB-C Alternate Mode does. This limitation makes DisplayLink USB graphics adapters and docking stations ideal on systems that do not have USB-C, or in instances where more displays are needed beyond available video outputs of a PC.
This type of connection comes in a couple different styles depending on whether USB 3.0 and higher transfer rates are supported (bottom graphic). Usually this type of connection is used to plug into USB devices that do not have a fixed cable connected, such as USB docking stations, USB hubs, printers, and others.
One of the first connectors for charging a smartphone, wireless game controller (such as the Sixaxis and DualShock 3), and other small devices such as external hard drives. Not commonly used today, but is still used in some cases. Most devices using USB Mini B are using USB 2.0, though a USB 3.0 variant does exist. This specification also added USB On-The-Go (OTG) functionality, though it is more commonly implemented with Micro USB.
A smaller connector that serves many of the same uses as the Mini B connector, with added optional features such as Mobile High-Definition Link (MHL) to allow devices like smartphones to output video to larger displays without requiring a dedicated port for video output.
The larger variant of USB-B is most commonly used for external hard drives for higher 5Gbps transfer rates.
USB-C, Thunderbolt™ 3, and Thunderbolt™ 4
The most recent USB connection, USB Type-C (USB-C), represents a major change in what USB can do. The connector is smaller, can be connected in two orientations, is able to carry substantially more power and data, and can directly carry video signals of multiple types (HDMI, DisplayPort, etc.) Intel has also adapted the USB-C connector for use with Thunderbolt 3 and Thunderbolt 4.
It is important to note that while all Thunderbolt 3 and Thunderbolt 4 connections are USB-C, not all USB-C connections can be used with Thunderbolt 3 or Thunderbolt 4 devices.

Self-Powered vs Bus-Powered USB Devices
While all USB ports provide some amount of power for attached devices, the available power may not be enough for certain high-current devices such as USB hubs or external hard drives. High-current devices usually come with their own power adapter, making them self-powered, in contrast to a bus-powered device that draws all of its power from the host computer's USB interface. Bus-powered devices can cause issues if they need more power than is available from the host machine.
Many of our devices that include power adapters, especially USB hubs, will function in either self-powered or bus-powered mode. However, even though the device may function, each additional device attached to the host computer reduces the total available bus power. If the power runs out, any USB device attached to the computer may suddenly disconnect. If this were to happen to a USB storage device, such an event could result in permanent data loss.
If a device comes with a power adapter, we recommend that the adapter stay connected at all times, otherwise the device may not function as designed.
Self-powered USB device - A device that takes all of its power from an external power supply
Bus-powered USB device - A device that takes all of its power from the host computer's USB interface.
I accidentally connected a 12V power supply instead of the included 5V power supply and damaged my hub. My devices attached to the hub may have also been damaged. What can I do?
Can the hub charge iPods/iPads and other smartphones?
Apple device charging behavior varies according to both the size of the device and whether it has a “Lightning” or “30 pin” connector.
Newer Apple devices with the “Lightning” connector, when attached to the BC 1.2 Standard compliant Flip-Up ports without a host computer, can charge at up to 1.5 Amps.
Older “30 pin” iPads will only charge when the iPad is turned off. When turned on, these older iPads will report “Not Charging”. 30 pin iPods, iPads or iPhones will charge only at the standard 500mA rate.
My External hard drives disconnect randomly or when I sleep/wake my Mac causing an improper drive eject error message.
Hard Drive Updates:
- Check for and update external hard drive firmware if available.
- For Intel based Macs, perform an SMC and PRAM/NVRAM reset SMC.:
- Perform an SMC reset: https://support.apple.com/en-us/HT201295
- Perform an NVRAM/PRAM reset: https://support.apple.com/en-us/HT204063
- Disable Power Nap on Mac (in power settings, disable for when connected to AC power and battery if the customer uses the hub while also on battery power).
- If possible, test the USB hub and hard drives with a Windows PC to see if the issue persists there as well.

Do Plugable products support the Apple SuperDrive?
Unfortunately Plugable products do not support the Apple SuperDrive.
The Apple SuperDrive has stringent power requirements that can only be met by directly connecting the SuperDrive to your host laptop. As a result at this time Apple recommends only using their USB-C adapter cables. You can find more information on that here -→ How to connect the Apple USB SuperDrive
If you have purchased a Plugable product to use with your Apple SuperDrive, and would like some additional assistance please do not hesitate to reach out. You can do so by emailing firstname.lastname@example.org, or going to Plugable.com/Support.
