Yes, but not up to 40w charging speed. Because the oppo reno3pro supports up to 30w fast charge, charging with 40w and the same fast charge protocol can only be charged by 30w at most.
reno3pro is equipped with 30w fast charge, the mobile phone has no voltage change, using direct charge mode, charging speed is still very fast, about 55 minutes can be fully charged, charging efficiency is relatively high, so it is best to use the original charger to charge.
