vivo fast charge and oppo flash charge are basically compatible, because they both use similar fast charge technology, namely VOOC (oppo) and FlashCharge (vivo) technology. This means that if you use an oppo flash charger that supports VOOC technology, it can be used to quickly charge a vivo phone that supports FlashCharge technology, and vice versa. However, in order to ensure the best charging effect and safety, it is recommended to use the original charger for charging. At the same time, it is also necessary to confirm whether the jack between the phone and the charger is compatible, because even if the fast charge technology is the same, the jack cannot be used when it is incompatible.
not in common use
oppo and vivo flash charging is not common,oppo and vivo flash charging technology is different, so it is not common. oppo mobile phone flash charging technology is VOOC flash charging,VOOC flash charging is OPPO independent research and development of fast charging technology, and applied for 18 patents, the fastest charging speed increased by more than 4 times, is the world's fastest and safest mobile phone charging technology. The flash charging technology of vivo mobile phone is dual-engine flash charging, and the dual-engine flash charging technology is a mobile phone fast charging technology, which is developed by vivo under the premise of compatible with the international mainstream fast charging protocol.
Because vivo fast charge and oppo flash charge both use VOOC (Voltage Open Loop Multi-step Constant Current Charging) technology, basically the same charging method, so the two chargers are compatible.
In addition, Huawei Super Fast Charge and OPPO Flash charge are also compatible, because they both use similar SuperCharge Protocol (SCP) technology.
It should be noted that although compatible, different brands of chargers will have an impact on the charging speed and safety of the device, so it is best to use the original charger.
Can not be compatible, can merge to try.
