when I bought my s7 edge I purchased 3 power banks in different mAh for on the go.... all of them terrible. yes they "charged" my phone, in about 5 hours... I couldn't use the phone meanwhile because the battery would drain faster than it can charge. I shelled out the extra couple of bucks for this one and as the other reviewers stated this DOES fast charge as if you where using the wall charger. you can also use your samsung fast charge cord with it if you need a longer reach (yes it comes with a cord about 6-8 inches long). this charger got me through disney world! yes it's on the heavier side (about a pound) but it's worth it.
