Galaxy Z Fold8 Ultra Desk Hub × Elecdov Qi2.2: The Best Foldable Mate Is Almost Ready
Quick answer: Elecdov W103S and CE19S already fast-charge your Galaxy S26 / iPhone 17 Pro / Pixel 10 at 25W Qi2.2 and your earbuds at 5W. Galaxy Z Fold8 Ultra (5000mAh, 20W Qi2.2 wireless, bottom-offset coil, no built-in magnets) is not yet in the Elecdov certified charging list as of August 2026—but R&D is in the final validation round. Bookmark this URL; we flip the status box the day the test passes.
W103S / CE19S current firmware = centred MPP25 for S26 / iPhone 17 / Pixel 10 + 5W buds.
Galaxy Z Fold8 Ultra = bottom-shifted Qi2.2 coil, 20W max wireless (not 25W), needs WPC Qi2.2.1 magnetic case (Belkin MSB023-class).
→ R&D stage: Last-pass offset-coupling + Ecooler thermal + FOD 0.3g + WPC IOP. No ETA, notification-only.
1. Why Galaxy Z Fold8 Ultra Breaks the “One Desk Hub Fits All” Myth
Samsung’s Galaxy Z Fold8 Ultra (July 22 2026, SM-F976x) ships a 5000mAh silicon-carbon cell, 45W wired, 20W Qi2.2 wireless, and no internal MagSafe-style magnets.[5,7](@ref) Because the foldable is wider and the coil sits toward the bottom half (not centre), Samsung itself tells users to align the bottom coil with the pad centre.[1](@ref) To hit MPP25 you also need a WPC-certified Qi2.2.1 magnetic case (e.g. Belkin Sheerforce MSB023, QI-27513, Aug 5 2026).
For a desk hub this matters: a charger tuned for centred iPhone/S26 alignment can suffer 5–8mm vertical coil mismatch on Fold8 Ultra, dropping power or triggering FOD retries. That is exactly the boundary Elecdov’s firmware team is closing.

3. W103S vs CE19S – Desk Hub Fit for Fold Owners
W103S – The travel + desk foldable essential ($49.49)
- Unfolds to 70×132×6.35mm, 324g, USB-C PD in, 25W phone + 2.5W watch + 5W buds.[3](@ref)
- Ecooler active fan holds <40°C surface at 25W—important when Fold8 Ultra dual-cell heat spreads wide.
- Coil array physically wide enough for offset Fold coil; only the MPP25 negotiation table is pending.
CE19S – The nightstand command center ($30.28)
- Carbon-fibre housing, dimmable clock, upright phone view, 15W phone + 5W buds + 2.5W watch.[9](@ref)
- Ideal for desk aesthetics buyers who also run S26/iPhone 17 as primary.
- Shares the same pending Fold8 Ultra unlock path as W103S.
4. R&D Update: The Five Gates Before Fold8 Ultra Unlock
- Offset coupling – vertical coil shift ±7mm at 20W, no power drop (>70% efficiency).
- MPP25 handshake – emulate Belkin MSB023 (QI-27513) case profile, lock 20W sustained on Fold8 Ultra.
- Thermal log – 5000mAh dual-cell charge curve on W103S Ecooler fan curve, surface ≤40°C.
- FOD 0.3g – 9-grid metal sheet test, fold hinge debris edge-case included.
- WPC IOP – cross-test with iPhone 17 + S26 + Fold8 Ultra on same puck, no protocol clash.
No hardware revision for current W103S / CE19S owners. Unlock ships as MCU firmware flash + recommended case list (Belkin MSB023-class or equivalent WPC Qi2.2.1 shell).
