45 watt super fast charging for note 9

[DJays]

can anyone tell me is it supportable for charging galaxy note 9 with 45watt super fast charger and does it affect battery life?

Note 9 doesn't support 45w charger. It doesn't affect the battery life because it will revert back to 18w even if you used the 45w charger. That being said, even if Note 9 supported 45w, I wouldn't recommend it because it doesn't give a huge boost in charging speed.

oh i see , thanks for your response , means that note 9 maximum is just 18watt even i used 25watt charger will be the same also?

[Jeremiah9534]

Yeah that's correct.

[DJays]

[Jeremiah9534]

Yeah only 15w. My mistake

Samsung Note9 is not able to fast chage with Adaptive Fast Charger and the  service man outside told fast charge chip is not working.

However it's able to "fast charge" with Samsung 25W & 45W adapter. Is it safe to use high power chargers?

I see it's gettting hot. Till what temparature Is  safe to use for Note9  charging ?

 How can i know what voltage and current it's using for charging (Ampere app already used)
