[Android Central Question]

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??

There shouldn't be any problems. The various quick charging protocols "talk" with the phone to check compatibility when you plug it in. If it's not compatible with the phone to do the turbo charging, the charger will default to traditional charging. This won't damage the phone, but may be slower than a fully compatible charger.
