This wireless charger is not compatible with the iPhone6/ 6s/ 7 or the Apple Watch.
We recommend using a QC (5V/2A) power adapter. When using a standard Apple power adapter (5V/1A) or a computer USB port to power the wireless charger, it is possible the power will be insufficient to charge your phone properly.

1. Why is the charger heating up when charging?
It is normal for the receiving coil or plate to heat up during the wireless charging process. We use a zinc alloy for better heat dissipation.
2. Why is my phone not charging when placed on the charging pad?
First, please ensure your phone is Qi wireless-charging compatible. Second, please make sure the phone is aligned with the center of the charging pad. Please remove phone cases thicker than 4mm. If you have any question about compatibility or alignment, please let us know so we can help you.
3. Why is the charging speed slow?
First, please make sure that the phone is properly aligned with the center of the charging pad. If your phone supports fast charging, it requires a QC 2.0 or QC 3.0 AC adapter (not included) for fast charge mode. Reducing the phone’s background applications may improve the charging speed.
4. Will it charge through a thick or rubber phone case?
The ESR Wireless Charger is compatible with most phone cases. However, phone cases thicker than 4mm (like OtterBox) may affect wireless charging.
