A:AnswerYes it's compatible with samsung galaxy note 9. My wifes phone is galaxy note9. .and its also compatible with my new phone note10+ .I would recommend it.
A:AnswerI charge my Iphone with it and have for 6 months. It is a great product. It does not get very hot which makes it very safe for a phone. When a charger gets hot it means the battery can break down and swell up. This is the reason I bought this charger is for the safety of it. Out of the box, this does not have a fast charger, but if you upgrade the charger it will be a fast charger. The only issue with fast chargers is that they put more wear and tear on your phone's battery. It's best to charge them at a normal speed.
A:AnswerPops,
That's correct, you lay a compatible phone on the pad and it charges. The newer Samsung and iPhones will work with it. I am using it with the iPhone 11 Pro Max.
I hope this helps.
