Ordered one too. Im curious, are you able to get the 25 percent increase off of a 2.1 amp charger? Most USB phone chargers, auto USB ports and backup batteries are just 1 amp. I personally switched all my chargers out to be 2.1 amp and I have a backup battery with 2 usb ports. One is a phone port that is 1 amp and the other is a 2.1 amp port for tablets. I hope this doesn't require some new 3 amp charger to get the speedy charge.
This car charger is nice because it is 2.1 per port
