Query: Good if all you want to do is transfer photos...

This is a cheap cable, which only performs cheaply. It will not power any device nor charge it. I have tried it with many different devices, connected to many different USB and power sources. It will transfer data however, but only if your device has it's own external power. Bear in mind though, that that is even iffy. I used this on a WD external hard drive, and whenever I did data transfers that were larger than 2 GBs or included more than 30-ish files, the cable wouldn't work and my hard drive would "eject" from my computer.If all you need this cable to do is transfer a few files quickly and without power, feel free to go for it. Otherwise, look for something else.
