The Galaxy Z Fold 8 and Z Fold 8 Ultra now support 45W wired charging, up from a rather meager 25W in the previous generation. How to fast charge the Galaxy Z Fold 8Robert Triggs / Android AuthorityTo optimally fast-charge the Galaxy Z Fold 8 series at 45W, you need a charger with USB PD PPS support that can supply 15V at 3A. If anything, picking the right charger now, with up to 21V PPS support, will ensure it’s futureproof for whatever gadgets you buy next. Likewise, several of Anker’s newer Prime chargers support Samsung’s required PPS profile, though it’s worth checking the specifications before buying, as support varies by model. The Galaxy Z Fold 8’s faster charging is finally worth taking advantage of.
