From what I have read, there is more to it than just the amps of the charger. The Qualcomm Snapdragon 800's Quick Charge spec calls for both the device (phone) and the charger to be compatible; and to some extent, the cable. To clarify, using the stock LG G2 charger with a standard micro USB cable will sometimes result in "Slow Charge".
What I'm looking for, and guessing that the OP is too, is what SPECIFIC chargers have some of you gotten that might not only charge fast but also "Quick Charge"? The BB Playbook chargers sound promising -- as they are dedicated chargers, and not a power cube + USB cable which seems to be the norm these days. Is it the Playbook "Rapid Charger" or a replacement Playbook charger? TIA.
