The oppowatch4pro can be charged using any standard USB-A charger, including phone chargers, computer USB ports, and power banks.

7.5w charging head power
The VOOC Watch flash charge used by OPPO Watch supports up to 7.5W charging power, and the charging time is also greatly shortened. The theoretical charging time is 75 minutes, and the power can be charged to 99% in about 40 minutes. 75 minutes should be the result of considering trickle charging, if it is only charged to 90% of the power use, the reduction in time will be more obvious.
The Oppowatch4pro can be charged using any standard USB charging head, such as the charging head of a smartphone, the USB port of a computer, etc. Simply connect the charging cable to the USB port on the charging head and plug the charging head into a power outlet to start charging. Please ensure that the charging head output voltage and current meet the requirements of Oppowatch4pro to avoid damage to the device or problems during charging.
