Power banks usually automatically adjust the output power, but whether the W number is automatically adjusted depends on the specific power bank design. Some advanced power banks are equipped with smart chips and voltage regulation technology, which can automatically match the optimal output power and voltage according to the needs of connected devices.
This intelligent regulation ensures that the device works in a safe and efficient charging state, avoiding overcharging or overheating. However, the technical level and functions of different brands of power banks may be different, so it is best to consult the product manual when purchasing a power bank to confirm whether it has the characteristics of automatic adjustment of W number.
Yes, within its own output power, can automatically change with the load. However, because the charging treasure is battery powered, mainly constant voltage output, the current changes in a certain range, so the output power is also changed.

Charging treasure is a rush ah, generally we use the charger is 800MA charging treasure current has 1A-2A, but 1A is fine, not too high on the battery is not good for the phone is not good 0
