As I said before, it really depends what exact Amp ratings you are comparing... If a charger is rated lower that a phone's charging circuit, it will certainly underperform, and will charge slowly. But if your charger's rating matches or exceeds the charging current required by phone, then it makes no difference.

I personally don't have an OG stock charger, so I don't have any experience using a charger rated specifically at 1.2A. I only have USB chargers rated at 700mA, 850mA, 1A and 2A. Plus, an assortment of other power supplies rated anywhere from 2A to 30A. Of course, I do see a faster charging when going from 700mA charger to 1A, and then to 2A, because the first two are under-rated compared to the phone's specs. However, once I go with 2A or the higher rated power sources, there's no difference at all.

Hope that explains it.
Optimus G F180S, VDT V23 (KK 4.4.2)
Galaxy S5, rooted stock 4.4.2
Venue 8, rooted stock 4.4.2

To whom it may concern: STOP nagging about pressing the freakin' Thanks button!!! It is rude, stupid, and annoying as hell. I am not an idiot who needs a huge in-my-face reminder to press it, and I will press it when I feel thankful, not because you asked for it!
