This is second wireless charger i have got from idoo both chargers are smart chargers even with my note 4 they did not over heat my phone i have been using the first one i purchased from them to charger my note 7 as it was one bad ones that could have had battery blow it never overloaded the phone it was always cool i have purchased a samsung smart charger and makes my phone warm

Because of how well my idoo charger has done i purchased this one i have my new phone and it does a fantastic job i can leave the phone on charger after it is charged and it does not feel warm at all

Charging port broke on my phone so i got this and a wireless charger

Works perfectly my husbands phone was having problems charging with the charger inserted into the phone
