You use the maker's charger and cable. But high speed charging is possible with other maker products. For me the high speed charge was never needed. That is, I'll take the slow charge and the longer battery life span.
So i bought an used Samsung s8 .. the cable that had with it seems like it was not original and the charging is very slow. (5 hours for 100%), then i tried Motorola turbo power from my brother and it charges in 1 hour for 100% .. much better, but is there any risk by using this charger on the phone??
