The key check
Vehicle and vessel outlets follow their operator's equipment, not automatically the destination country's grid. Check the posted outlet rating and operator rules.
| Item | What to read |
|---|---|
| Device | AC INPUT voltage, frequency, current and earth requirement |
| Adapter | Input/output plug variants, earth path and AC rating |
| Property | Exact socket, supplied voltage and condition |
What changes the answer
Onboard power may be generated, converted or limited by the operator. A country voltage chart therefore cannot describe every ship cabin, train seat or aircraft outlet. Use the posted socket rating and operator instructions, particularly for high-load devices or medical equipment.
Decision table for this question
| Situation | Meaning | Next step |
|---|---|---|
| Ship cabin outlet | A country chart may not describe ship generation | Read the operator's cabin power label |
| Train-seat outlet | Power and load limit can differ by train | Check the operator's posted rules |
| Aircraft seat outlet | Use may be restricted or unavailable | Ask the airline, especially for medical equipment |
Use this before plugging in
- Find the AC INPUT label on the exact appliance or power brick. Write down the stated voltage and frequency range.
- Confirm the actual destination outlet voltage and socket variant; a country reference cannot tell you what a particular room has.
- Trace the physical plug and protective earth through each adapter. Read the lowest AC current rating in the chain.
- If a condition is missing or the maker excludes the appliance, leave the setup unconnected and seek a rated alternative.
Common shortcut to avoid
A familiar plug shape or a broad USB wattage claim is not a substitute for AC voltage, grounding and load checks. The distinctions in the table above are screening data; they do not certify a particular hotel outlet or product.
