A:AnswerYes it will. As long as it is the 8, 8+, or X. It uses the Qi charging technology and will charge any phone that uses that technology.
And NO, it is NOT just for Samsung devices.
A:AnswerDoesn’t support iPhone 8 for fast charging. It charges it fine but I’m not sure if any chargers currently fast charge it yet. At least none I wouldn’t trust with my phone
A:AnswerIt should work with your phone if it has the Qi charging capability. Check your owners manual and it will let you know if you have that feature. If you do not have it you can purchase a Qi adapter that sticks to the phone battery and it will work as well.
