Does this cable provide power to the host device (phone) or the slave device (peripheral)

Sorry the one I received did not work and currently having an issue since they charged me for shipping on the free shipping ad.

The cable provides power only to the peripheral. The reason is that the OTG host protocol requires it.Otherwise, the host device will provide power to the peripheral. The host device always runs off its own battery/power.

Didn't work on Samsung s4 however tried on nvidia shield tablet and it did charge tablet and powered up 2tb external hard drive, just charge $19.99 for shipping

Gets power from switched device. I purchased a universal power supply but it made no difference in my case.

The cable that comes out of the device is a USB terminal that can be connected to an included USB wall plug or another USB power source. Not worth the money.

It has a rj45 cable (network cable) that goes from the controller to the device. No power is needed.

No. The cable is only made to increase the power to a device by using two usb port to provide power to one device.

It does not provide power to any device. It is powered but does not provide power (other than through the USB ports)

Not sure. I used one end to connect to an ac adapter and the other to transfer data, but it didn't work, it didn't generate enough power. So, I'm thinking depending on the device, probably not. Hope this helps

I just use this cable to charge my stuff. I'm sorry I can't deliver any further information. Thanks.

This cable is capable of charging the tablet, while the USB port is in use. The catch is the tablet won't allow it, unless you root the tablet and install a kernel modified to allow charging while in host mode.

I do not know the proper answer, but I presume the answer involves factors of power load and data throughput. Peripheral USB devices that have their own power source should result in more devices being workable. Likewise, more devices of low power draw can be supported than those that require higher power from the host device. As for data bandwidth, it stands to reason that more devices will have to share the maximum data transfer of the host device port. Even though I can't provide a definite answer, perhaps this will help identify issues to research further.

Both, power adapter and via a USB connected to PC or laptop. Its the same type of USB as most smart phones use. I use the same cable that my Google nexus 5 uses.

No, I draws its power from the mother board. You may be thinking of USB hubs, which often require external power. Hope this helps.

I use a PC, but it does support data transfer as well as charging. I have had the cable only a short time, but it is working just fine.

The cable itself is about 6 inches from the hub to the single usb connector. As far as power it will supply power to plug-ins but if it is a power hungry device it may require an AC-powered usb hub.

No this cable is not meant for that function. It's meant for phones with OTG capability. The male micro plugs into your phone for data transfer; the larger female USB interfaces to devices that a normal PC interfaces to like keyboards, drives etc; the female micro accepts POWER for those devices IF required. No data transfer via that path. But look - for $10 or so you could always buy one and see what happens I guess. But I'd bet my hat it won't work. Regards, Steve

Physically speaking yes, but not sure of electrically. The cable is a USB OTG cable, enabling the device like a phone or tablet to behave as a host, connecting to things like a keyboard. For example, I use it with my Nexus 7 and a USB keyboard. This is necessary since a tablet is normally considered a storage peripheral when connected to a computer host. Now if you connect the adapter to a charger, you need a special USB cable, which may or may not work per USB OTG. I would rather go with a regular micro USB cable.

It includes a micro-usb cord that powers the device from your computer and transmits data from the built in USB hub. You can buy the extra power adapter, but it is not necessary.
