Galaxy Watch Ultra 2 × Elecdov Qi2: The Best Travel Charging Mate Is Almost Here
Quick answer: Elecdov W103S and W98S already fast-charge your Galaxy S26 / iPhone 17 / Pixel 10 at 25W Qi2 and your earbuds at 5W. Galaxy Watch Ultra 2 (800mAh, WPC 10W high-frequency, launched July 2026) is not yet in the certified charging list—but Elecdov R&D is in the final testing phase for Ultra 2 compatibility. Bookmark this page; we will ship the unlock the moment lab validation passes.
W103S / W98S watch zone = Qi2 2.5W (certified for Galaxy Watch 8 / Ultra 1 / 7 / 6…).
Galaxy Watch Ultra 2 = WPC 10W high-frequency (not Qi2 MPP). Current pucks will not negotiate 10W with Ultra 2.
→ R&D stage: Final coil-match + Ecooler thermal + FOD safety pass. No ETA yet, notification-only.
1. Why Galaxy Watch Ultra 2 Changes the Charging Math
Samsung’s Galaxy Watch Ultra 2 (announced 22 July 2026, SM-L715x) ships with an 800 mAh silicon-carbon cell—36% larger than Ultra 1—and keeps the same WPC-based 10W high-frequency wireless charging (5V/2A) profile. It is not a Qi2 MPP device; the watch coil exemption means no magnetic 2.5W Qi2 handshake, it expects 10W WPC negotiation.
For travelers this means: a 3-in-1 Qi2 phone/buds/watch dock must run two different wireless protocols at once—25W Qi2.2 on the phone side, 10W WPC on the watch side. That is exactly the boundary Elecdov’s firmware team is crossing right now.

3. W103S vs CE19S – Travel Fit for Ultra 2 Owners
W103S – The carry-on essential ($49.90)
- Folds to 2.76 × 0.25 × 5.20 in, 324g, one USB-C PD brick powers all zones.
- Ecooler active fan cuts coil temp up to 15°C—keeps 25W phone output stable in hot airports.
- Watch puck physically ready; only the negotiation table for 10W WPC is pending.
CE19S – The hotel nightstand command center ($34.50)
- Built-in dimmable clock, upright phone view, 2.5W watch zone.
- Ideal for 4+ night stays; pair with W103S in laptop bag for daytime.
- Same pending Ultra 2 unlock as W103S.
4. R&D Update: Last-Mile Validation Explained
Elecdov’s Samsung charging team confirmed the Ultra 2 track is in Stage 4 / 5:
- Coil geometry rematch – align WPC 10W flux with existing puck array.
- Power negotiation – emulate Samsung EP-OL715 puck handshake at 5V/2A.
- Thermal log – run Ecooler fan curve against 800mAh charge curve (0–100%).
- FOD & over-voltage guard – ensure no false trip when Ultra 2 + phone + buds stack.
- Certification re-run – WPC lab sign-off before public firmware push.
No hardware revision needed for current W103S / CE19S owners. Update ships as puck firmware + controller MCU flash (or optional Ultra 2 puck swap for early adopters).
