A:AnswerA couple things I noticed when I first started using mine that may help you.
1. I had a magnet on the back for my phone mount in the car. That would not let it charge.
2. I use the otter box defender case and it is quite thick. I have to adjust the placement of the phone on the charger and slightly press down until it makes the sound.
It took some playing with hope this helps
A:AnswerAny 2 amp micro USB car charger will work with this charging pad for your vehicle.
I have used it with my note 4 high speed charger in my vehicle with no issues.
A:AnswerYes, that is what I have and it's a dream come true if you hate plugging in cords all the time. The only draw back is, if your case is to thick you will need to remove it it first. I bought a case recommend for use with the charger.
A:AnswerNo, it will not. A Galaxy Note 3 and a Galaxy 5 require their back cover to be replaced with one that is compatible with the wireless chargers. I am not sure whether Samsung, or an OEM, offers a replacement back cover for the Galaxy Note 2.
A:AnswerYou need to use the high output fast charge wall adapter or it will only charge at the lower rate. The fast charge adapter does come with the complete version. I have seen some places that only sell the charge base without the fast adapter so be careful what you buy.
