Travel Power Compatibility Checker
Enter your device specs and the destination voltage to see whether a simple plug adapter will do or if you need a heavy-duty converter and frequency caution.
Examples
- Spanish hair dryer 1,400 W rated 220–240 V heading to Japan at 100 V, plug mismatch, 30 % margin ⇒ Power prep: add plug adapter; converter capacity 1,820.00 W; frequency compatible (50 Hz)
- Laptop 65 W rated 100–240 V with matching plug in Canada (120 V, 60 Hz) ⇒ Power prep: plug matches destination; converter not required (0.00 W); frequency compatible (60 Hz)
FAQ
How do I know if my device is dual voltage?
Check the rating label—if it lists a voltage range like 100–240 V, it will operate on both low and high mains supplies.
What size converter should I buy for motorised devices?
Use a margin of at least 50 % above the wattage because startup surges can briefly double the draw.
Does frequency really matter for travel gadgets?
Most switch-mode supplies handle 50/60 Hz, but single-speed motors and clocks may run slow or overheat when frequency is off.
Additional Information
- Converter capacity multiplies the device wattage by the safety margin so resistive loads have breathing room.
- Frequency compatibility compares destination Hertz with the min/max range on your charger or appliance.
- Plug adapter guidance assumes Type A/B sockets by default—toggle the flag when your plug already matches.
