✓ Dual-Voltage Devices (Safe with just a plug adapter)
Most modern electronics (Laptops, iPhones, iPads, Camera battery chargers, electric toothbrushes) are dual-voltage. Look for a label that says: INPUT: 100-240V ~ 50/60Hz. These adjust automatically to international voltage.
✕ Single-Voltage Heating Appliances (Hazardous!)
High-wattage heating appliances (Hair dryers, curling irons, electric kettles, blenders) often only support 110-120V. Plugging a 120V hair dryer into 230V without a heavy-duty step-down voltage converter can cause a fire or blow a fuse.
About this tool
How to use it
- Select your home country where your electrical appliances and electronic chargers were purchased.
- Choose your travel destination country to view local socket types, voltage levels, and frequency.
- Review the instant compatibility status to determine if you need a physical plug adapter or a voltage transformer.
- Consult the dual-voltage checklist to verify whether your laptop, phone, or hair dryer is safe to plug in.
Why it matters
Plugging an incompatible electrical appliance into a foreign wall socket can fry sensitive electronics, trigger power surges, or ruin high-wattage heating elements. Knowing your destination's plug types (Type A through N) and voltage ensures safe international travel.
When to use it
Use this reference before packing for international trips, vacations, study-abroad programs, or business travel.
Common questions
What is the difference between an adapter and a voltage converter?
A plug adapter only reshapes the physical prongs so they fit into foreign wall sockets. A voltage converter (or transformer) actively steps electrical voltage up or down (e.g. from 230V down to 120V).
How can I tell if my phone or laptop is dual-voltage?
Inspect the fine print printed on your power brick or charger. If it reads 'INPUT: 100-240V 50/60Hz', it is dual-voltage and works worldwide with just a physical plug adapter.
Can I use an American 120V hair dryer in Europe (230V)?
Only if the hair dryer features a physical dual-voltage switch (120V / 240V). Standard single-voltage 120V hair dryers will overheat and break immediately if connected to 230V outlets.
Which countries use 100V-120V power?
North America (USA, Canada, Mexico), Japan (100V), parts of the Caribbean, and parts of South America operate on 100-127V. Most of Europe, Asia, Africa, and Australia operate on 220-240V.
