66W charger, if you see from other mobile phones whether your mobile phone product supports this fast charge protocol, if you do not support the use of this 66-watt high-speed charger will damage the mobile phone battery, the mobile phone charging process is also very hot, no explosion risk, so the choice of 66W charger must see whether the mobile phone product model supports fast charge function, I hope my answer helped you.
This is no problem as long as the charging protocol supports it, because its charging power is backward compatible.
