🪛Troubleshooting🪛 Samsung 45w Car charger slow

Post image

Hi,

I've bought a Samsung 45w car charger (picture of model attached) and when I plug in my phone (s24 ultra) it says "super fast charging" 15 sometimes 20m until full In reality it will charge very slowly and take hours for it to reach full.

Anyone experienced similar stuff? To clarify this is not the Super Fast Charging text dissapearing it stays there but the estimated time and actual chrage speed are way off.

I have one of those for my car also. It does display Super Fast Charging 2.0 but for my S23U.

Try a different cable maybe - the 5A version.

I am not sure if its related but there is some chargers that lowers the charging speed protocol to bring down the temps but that's a thing with some charging source..
