In the first two days it charged my Samsung S8+ as fast as its original Fast charge wall box that came with the phone, but on the third day it didn't

75+%.I disconnected the Anker wireless charger and connected my original fast charge wall box and the time estimate instantly changed from 1h & 39m to 59m ! to charge the rest of the battery from 42% -

Make sure you read the directions and use the correct wall plug or you might get less desirable results.

I was initially disappointed that the instructions indicated it would only work with a more powerful wall charger than the one I have for my phone

Perfect with the proper wall charger

Its much faster just to use the rapid wall charger with the supplied iphone cord.

Charging could be quicker,, I even bought the proper wall adaptor, but its not a fast charge by any means

Must buy a compatible wall plug to make it work.

Even with a rapid charger wall adapter its pretty slow to charge.

This ANKOR Brand worked as a generic fully compatible

I have a 4-port ANKER PD that also supports USB-A; the fast charge functionality does not appear to be working while connected there either

I need to adjust the position of my iPhone 11 several times before finding the position in which it can charge, which is annoying as you’re lying in the dark at night
