With the ever-increasing number of phones and tablets in my home. I've been contemplating changing some of the electrical fast charging charger 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.
