Hello,

I bought a smartwatch and it does not have a charger. The capacity battery is 230mAh. In the manual, they wrote input parameter should be 5V = 500mA.
If I choose a charger with high output power (15W (5V/3A), (5V/2.4A), 20W, or 65W), will the watch's battery be damaged?
Does the charger with fast charging technology and Power Delivery damage the smartwatch?
Please see the attached image. (The first image is from the smartwatch manual and the last three are USB adaptors)
I don't know what USB charger/adaptor to buy.

Thanks in advance
