1, can be charged normally, the voltage and current required for mobile phone charging is generally automatically controlled by the internal circuit of the mobile phone, that is, the mobile phone itself decides.
2, the basic original standard or regular brand of fast charger will have a built-in smart chip, its biggest role is to automatically identify the voltage and current required by the phone, and then adjust their own intelligent, to provide a suitable and safe current charging for the phone.
3, when the fast charger recognizes that your phone does not support fast charging, it will automatically charge the phone in accordance with the ordinary charging mode, and will not blindly charge.
I bet you can charge a cell phone. When the 66-watt charger charges the ordinary mobile phone, the fast charge protocol he executes should be the lowest of the kind of protocol, that is, the power management chip in your mobile phone is executed by the protocol, even if it is to charge your fast charge mobile phone, he is not always 66 watts state, when charging the fast charge mobile phone, there are generally three states, one is the highest power state. Then a steady state, and finally, a trickle-charge state. Hope to help you!
