If you're looking for a spare quick-charger, go ahead and pull the trigger on this wall charger from Aukey, currently on sale at Amazon for just $15.
This one's among the official accessories licensed by Qualcomm. And it's basically just a solid wall charger at a great price that very much looks and feels like it could have come from one of the smartphone manufacturers themselves. The black plastic matte finish is nicely done, the official Qualcomm Quick Charge 2.0 logo is prominently displayed, and, well, that's it.
Output is rated at 5 volts at 2 amps, 9 volts at 2 amps, and 12 volts at 1.5 amps.
Like every other quick-charge wall charger we've seen, it's not small. But you really can't beat the sale price of $14.99.
