Physical fit
A plug adapter changes the connection shape. It does not change voltage or frequency.
TRAVEL ELECTRICAL CHECK
Three checks.
One clear answer.
Wondering if a travel adapter (plug adapter) is enough—or if your device needs a voltage converter? Enter the rating printed on your device. We compare voltage, frequency, and plug shape separately.

KNOW THE DIFFERENCE
An adapter is not a converter.
Electrical pressure
Your device’s complete input range must cover the local nominal supply. A mismatch can damage equipment or create a hazard.
Alternating current rate
50 Hz and 60 Hz are not interchangeable for every device. A transformer does not normally change frequency.
When is a travel adapter enough?
A travel adapter, also called a plug adapter, helps when your plug does not fit the destination socket. It can be enough only if your device’s stated voltage and frequency cover the local supply. If either electrical rating does not match, a plug adapter cannot make the device safe to use; check the manufacturer before considering a voltage converter or transformer.
What does 100–240V · 50/60Hz mean?
It means the manufacturer rated that device or power supply for inputs from 100 through 240 volts and for both common mains frequencies. You may still need a plug adapter.
Voltage-conversion equipment
If voltage does not match, an appropriate converter or transformer would have to supply the voltage your device requires and handle its actual power. Heating appliances, motors, timing-sensitive and electronically controlled equipment need particular care. This checker does not recommend converter capacity.
SOURCES / METHODOLOGY
Conservative by design.
Country supply records are compiled from the World Standards country table, which references IEC World Plugs conventions. Plug/socket systems standardized by national standards are catalogued in IEC/TR 60083. Adapter and dual-voltage explanations are cross-checked against Electrical Safety First guidance.
- Country voltage, frequency and socket table
- IEC/TR 60083 — national plug and socket systems
- Electrical Safety First — using electricals overseas
For destinations with multiple published voltages or frequencies, a safe verdict requires the device to cover every listed value. Socket letters are compared exactly; listed socket types are not assumed to accept one another.
Limit: This tool compares the ratings you enter with published nominal supply information. It cannot inspect your device, adapter, outlet, grounding, wiring, or local installation. Check the manufacturer’s instructions and local requirements when uncertain.
