Is this cable designed to supply power to usb devices?

No it wont. USB host will provide power to bridge to convert USB signal to eSATA signal. It is a USB device to eSATA host, not the other way around. Meaning it allows to use a eSATA device in USB port of your computer

No. I had to make one. I only use mine for a laptop. Not sure how much draw it has if you run it at capacity. Could blow a fuse or worse... Usually 400w and lower inverters come with those cables depending on your needs.

NO! Only for communication between an APC UPS and a computer via USB. This is not the cable you are looking for. Hope this helps!

They don't have to be. The two black connectors are power and data, the white connector is power only. The purpose of this cable is to power a device that exceeds the limit for a single USB 2 port. Note that USB 3 ports have more power and shouldn't need a Y cable. It is possible to plug the white plug into a separate USB power adapter. This is chancy because it is possible for the power to feed back into the device the black plug is attached to and damage it. For some devices this is the only way to solve a power issue.

Yes rather well, but need to keep in mind high powered USB devices will need external power. Adapter is meant more for storage or external wired keyboard/mouse

No. The extra USB connection is to provide more power to one device than a single connection allows. Some hard drives need more power and that's what this cable is for.

No. The sole purpose of the USB port is to provide a power source for other portable devices.

If you want only usb cable, yes. It is not AC powered, though. I use one to supplement an AC powered 4-port USB hub.

No. It is not intended for that purpose. It is intended to charge electronics that charge through usb. Laptops require a higher input to charge them that usb can give

I'm donating it so it's packed away right now. I seem to recall a cable that had a standard A connector on it. Whatever it was, it didn't meet my needs, and I bought a 2 port front panel USB 3 unit.

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

No this cable is not capable of charging your device it only provides secondary power to your USB device that is connected

It is only for devices with a micro USB port. The USB on the wire is exclusively for power supply.

I don't think so I tried running a couple of devices directly off the cable and it actually would fail, it works great connected to a powered usb hub

Yes. Keep in mind though that you'll probably need to use two USB cable spots to power the device. It's unusual but works fine.

Not really. It only charge USB devices iPad, phones etc. Computer needs much higher voltage.
