alright
If you can't mix it, the phone is not afraid of being charged.
Because even if you use 20\/18W fast charge, the actual output power is not always maintained at the maximum. There will always be a time when this curve drops to 5W... After the phone is charged to 80%, the voltage will also be reduced to 5V. It's the same voltage and current, and if you change the charger output, it hurts the battery
So, does mixing different power chargers hurt the battery? Not hurt ！！！！ With high-power (here refers to > 20W) charger in the end has no effect on the battery? No!! Use it when you need it. If you really want to protect the battery, use fast charge during the day when you are anxious to charge, use 5V1A when you are not anxious to charge at night, don't think so much.
Remember to turn on \"Optimize Battery charging\".
