Absolutely does what it claims - this cable can make a big difference when charging certain Android devices,
Verified Purchase(What is this?)

I've read a few reviews here which say this cable is snake-oil. I'm here to rebuke those claims!
I recently purchased a 2A ThinCharger (ASIN B008A5DC6G) but found that it would only charge my Motorola RAZR i (XT890) at the slower USB (500mA) rate. You can tell this because the device shows "Charging (USB)" in the battery settings. I tried a variety of USB cables with this charger but they all resulted in the same slow charging. I had heard previously that shorting certain pins on the USB cable would force the device to use the higher speed charging mode, but I didn't want to fiddle around with that and so ordered this cable instead.
I can categorically confirm that when I use this special cable my RAZR i charges much faster and the battery settings show "Charging (AC)". So it does make a difference, although presumably this only applies to those devices which were previously charging at the slower USB rate.
For me then this cable does everything it promises.
