The Find X6 Pro will feature 100W SuperVOOC, which would be a new record for an Oppo flagship, while the standard Find X6 would handle up to 80W rates

Basic wired 5V/2A charging and 5V-11V/7.3A, which is equivalent to up to 80W SuperVOOC, are supported by the Oppo Find X6 with model number PGFM110. The phone will theoretically work with the 100W VCB8JACH/VCB8JBCH adapter.
Only the flagship is eligible for the 100W tariffs. The PGEM110 phone, which is purported to be the Pro, will support the 11V/9.1A charging mode and include the same SuperVOOC adaptor as the standard model.
There is no information on the battery capacity of these phones. We must wait and see if the Find X6 will follow the Find X5 flagships of last year, which had the same charging rates but different sizes.
