Your original vivo charger is designed to work with your phone and deliver the fastest charging speed it supports.
A charger from another brand can still charge your phone, but it may take longer to reach the same battery level.
Fast-charging technologies vary by brand. A charger designed for another brand’s fast-charging system may be unable to activate vivo FlashCharge, even if it fits your phone and advertises a high wattage. When FlashCharge is unavailable, your phone charges at a standard speed.
If you notice that your phone charges more slowly after switching chargers, try using the original vivo charger and charging cable that came with your phone. This combination is designed to support FlashCharge on your device.
