With the ever-increasing number of phones and tablets in my home. I've been contemplating changing some of the electrical fast charging chargers with USB ports. My concern in light of some of the news stories I've read is about exploding from using incorrect charging adapters. Do most USB AC adapter wall chargers play nice with phones and tablets? What specifications should one be aware of when looking at the OEM charger as compared to one incorporated into a wall outlet? Thank you.

I think the first critical specifications are volt & ampere for output DC.
For example, my quick charger supports either 5V 2A or 9V 2A.

The 2nd important specifications are Volt & Hz for input AC.
My quick charger supports 100~240V 50 or 60Hz.
