Anker Quick Charge 3.0 (and QC 2.0) Car Charger
Sadly the Galaxy S7 and Galaxy S7 Edge doesn't do Quick Charge 3.0, although the processor inside is capable of delivering those blazing fast recharging speeds. QC 3.0 recharges a phone from 0-80% in 30 minutes, but could harm the life of the battery in the long run. This could be why Samsung stuck to Quick Charge 2.0, as it's very fast, effective, and preserves the life of the battery by slowing to regular speeds after a certain point.
Ankers tiny little car charger offers both Quick Charge 2.0 or is future-proof and has Quick Charge 3.0 as well. Meaning those who get the LG G5, HTC One M10, or some other tablet later in the year, can most likely enjoy fast charging on the Galaxy S7, and any other device later in the year, or in 2017.
It's small, fast, effective, and cheap.
