A:Answer What kind of phone do you have? I'm assuming it allows for wireless charging. Make sure you position your phone's wireless charging component directly aligned with the one inside the sanitizer. Also, if you're charging while sanitizing, I've read that your phone could move while inside. Try it again but pay attention to where your phone is after sanitization. And also just try using it without sanitizing and see if it charges. Honestly, this things doesn't sanitize. My wife tested it in her lab and the bacteria levels on the phone didn't go down after sanitizing. Returning it.
