Ive read a bunch of threads on this, but Im still confused. I own an LG Nitro (around 1800 mAh battery). The stock ac charger is 1.2 amps. I want to buy a car charger but am unsure about how many amps the phone will use (Ive seen 2.1 and 1 amp chargers). So, what is the max number of amps that the phone will charge with, and is there any danger with charging the phone with a high-amp charger?
