The best-supported fast-charger choices for the Galaxy Z Fold8 Ultra and Galaxy Z Fold8 are Samsung’s 45 W and 25 W USB-C adapters, respectively. Samsung specifies different charging capabilities for the two phones, so the standard Fold8’s 25 W example should not be treated as the Ultra’s maximum-speed option. For wireless charging, Samsung lists its Wireless Charger Duo for both models, but does not establish a generation-specific maximum rate for that accessory in the available product information.
This guide focuses on those documented options rather than ranking 15 unverified third-party chargers. Samsung’s published charging figures provide a useful basis for choosing an adapter, while current prices, inventory, and model-by-model third-party compatibility are not established here.
Which charger should you choose?
| Phone or use | Best-supported option | What Samsung’s figures mean |
|---|---|---|
| Galaxy Z Fold8 Ultra, fastest documented wired option | Samsung 45 W USB-C Power Adapter and a 3 A USB-C cable | Samsung specifies up to 45 W wired charging and estimates up to 63% in around 30 minutes under its internal lab conditions. [Samsung Support US; Samsung launch announcement] |
| Standard Galaxy Z Fold8, documented wired example | Samsung 25 W USB-C Power Adapter and a 3 A USB-C cable | Samsung estimates up to 55% in around 30 minutes in its internal lab conditions. This is the standard Fold8 example, not the Ultra’s maximum-speed choice. [Samsung launch announcement] |
| Either model, charging without plugging in | Samsung Wireless Charger Duo | Samsung lists the Duo as a wireless charging option for both phones. The available product information does not establish an exact generation-specific maximum rate for this charger. [Samsung Support US; Samsung Support US] |
| Replacing a cable | 3 A USB-C charging cable | Samsung specifies a 3 A USB-C cable with the adapters in its timed estimates and recommends using the supplied cable with a compatible adapter. [Samsung launch announcement; Samsung Support US] |
Samsung says its adapters are sold separately and recommends Samsung-approved chargers and cables. Prices and current stock are not established here. [Samsung Support US; Samsung launch announcement]
What charging speeds do the two phones support?

Samsung Wireless Charger Duo: for shared wireless charging
Samsung lists the Wireless Charger Duo as a wireless option for both phones. It can suit a desk or bedside setup where placing a phone on a pad is more convenient than connecting a cable. The available product information does not verify a specific Duo generation’s maximum charging rate for either phone, so do not infer that its rate necessarily matches the phone’s maximum wireless specification. [Samsung Support US; Samsung Support US]
For the Ultra, placement matters: Samsung says its wireless charging coil is toward the bottom of the device. Align the phone carefully on the pad rather than assuming the center of the phone will line up with the charging area. [Samsung Support US]

3 A USB-C cable: the documented cable condition
Samsung’s charging estimates specify a 3 A USB-C cable alongside the adapter. Samsung support recommends using the supplied cable with a compatible Samsung adapter. If replacing it, check the cable’s specifications and approval rather than assuming every USB-C cable performs identically. [Samsung launch announcement; Samsung Support US]
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.How to pick without overbuying
- For a Fold8 Ultra and wired speed: choose Samsung’s 45 W USB-C Power Adapter and a 3 A USB-C cable.
- For a standard Fold8 and wired charging: Samsung’s 25 W adapter is the wattage used in its published timed estimate.
- For either phone on a wireless pad: Samsung lists the Wireless Charger Duo; verify the exact accessory’s specifications before expecting a particular rate.
- When replacing a cable: follow Samsung’s 3 A cable condition and support guidance.
Samsung support pages say both phones support Super Fast Charging 2.0 and list 25 W, 45 W, 50 W Duo, and 60 W adapters among compatible adapter options. These listings do not establish that every option delivers the same rate to both phones. Match the adapter to the model-specific charging figure above. [Samsung Support US; Samsung Support US]
