Works great for quick charging of phone.
This is a great charger, works really well and very fast as advertised.
The thing is, I never need to do that with my wall quick charger which is also by aukey, so I'm going to give the benefit of the doubt that's its most likely the phone or cables as aukey makes fantastic charging products... quick charge works great with my galaxy s6, s8+ etc.
Used for the charging of my S9+.
The charger is great.
It performed the same as the one it replaced, it fast charged my phone but would only slow charge my tablet.
When the phone is connected to a compatible fast charger - 'fast charging' notification comes on the phone screen - but with this charger - it only says ' charging' and it takes a long (usual) time to charge.
I have the Aukey quick charge wall charger for this phone and it works great and DOES quickcharge with my Galaxy s7 Edge.
Rapid charge Works 50% of the time the other times it was either slow charging or just cable charging.
It charges, just not fast.
