If you get a wireless charger get the Samsung Fast wireless charger. It is built to work with your phone for better charging. That is the only charger i use. I put it on the fast wireless charger before i hop in the shower in the morning and its all charged up and ready to go in a little over an hour. The Samsung Fast Wireless Charger has a fan built in that kicks on when its fast wireless charging. The Fan does not run if it you only have the phone set to normal wireless charging speed. With that being said be sure to turn on Fast Wireless Charging in Settings under Battery.
