After lot of thought, I bought the Sony CP-AD2 charger for my Sony Xperia ZR phone. The biggest worry was the 2.1 Ampere rating of the charger and it’s compatibility, as the default in-box charger was of 1.5 Ampere.
Fortunately, the 2.1 Ampere charger worked very well. In fact, it the phone charges to 100% in about 66% of the time it would normally take with the 1.5 Ampere charger.
