Will my Smartphone power setup work in Saint Martin?
For Saint Martin, verify the exact smartphone equipment instead of relying on a country-level assumption. For a Smartphone, the item connected to wall power is the phone wall charger. Saint Martin is listed at 230 V / 60 Hz; read the exact equipment label for charger INPUT voltage and supported charging protocol before connecting it.
Travelers arriving with 100–120 V-only equipment need a separate voltage decision. Plug shape alone does not settle that question for a Smartphone. Across different accommodations in Saint Martin, a tested smartphone power setup is easier to repeat.

Saint Martin power: C · E · 230 V · 60 Hz
See the Saint Martin power plug guide →Do I need a plug adapter for a Smartphone in Saint Martin?
The C · E outlet family answers plug fit for a smartphone, not whether it accepts 230 V. Saint Martin uses C · E. If the plug on the phone wall charger does not match, a correctly rated plug adapter can solve the physical connection only; it does not change 230 V.
