Does the charger receiver work with my phone that is of a metal back cover?
Yes, the device works well with the phone that is of a metal back cover, but please put the charger receiver on the back of the metal cover, do not install it inside your phone, if not it will stop the phone to receive signal. There might be a minor electromagnetic interference to apply the wireless charging receiver with the metal cover together, the best and simple solution is to put a paper that is 0.007-0.01inches between the metal cover and the wireless charger receiver. The paper separates the metal cover and the wireless charger reciever to eliminate operating frequency.

What should I pay attention to?
1. With 5V/1A higher output, it gives the fastest wireless charge that you can get on the market, but not as fast as QC2.0 or QC3.0 [Normally it takes around 5 hours for full charged]. But some of our customers said the wireless charger receiver worked slow. Since they used a normal wall charger that is lower than 5V 2000mAh output. We suggest to use a wall charger that is of 5V/2A output or a QC3.0 Charger, and pls be sure your wireless charger supports fast charge.
2.The ribbon is a little bit weak. Pls DO NOT FOLD the ribbon, and do not install an uninstall FREQUENTLY.
3. Pls hold the housing of the connector of the wireless charger to pull the USB connector out from your phone when unplugging, if not, the connector would be damaged.
4. If you need fast charge, pls don't play your phone during charging.

These USB Type C smart phones that don't have wireless charge built-in work perfect with the charger receiver:
Xiaomi Mi5/Mi5 Pro, LG G5/V20/Nexus 5X, HTC M10/10, OnePlus 3, Nokia N1, ZUK Z1, Huawei P9/Mate 9/Nexus 6P, Google Pixel XL 5.5" ONLY, NOT 5.0" and more.
