What the AI looks for in Power Converters

Check the device label first
If the device reads 100-240V, no converter is needed, only a plug adapter. Most phone, laptop and camera chargers are dual voltage.
Wattage headroom
Rate the converter at 2-3x the device's wattage for motors, compressors and pumps. About 1.5x is enough for resistive loads. Startup surge on motor loads exceeds their running watts.
Transformer vs solid-state
Use solid-state 'travel' converters only for simple heating appliances. Electronics and motors need a true transformer. Solid-state converters output a chopped waveform that can damage electronics.
Frequency
Voltage converters do not change between 50 Hz and 60 Hz. Clocks, turntables and some motors run at the wrong speed or overheat on the other frequency.
Grounding
Choose a converter with a grounded three-prong output if the appliance has a ground pin. It preserves the appliance's shock protection.

Brands that matter

  • LiteFuze: Step-up and step-down transformers across many wattage sizes.
  • Simran: Long-running maker of household voltage transformers.

What to avoid

  • Running hair dryers or other high-wattage heating appliances through small travel converters for long periods
  • Converters rated exactly at the appliance's wattage
  • Using a converter on a device that is already dual voltage

Questions

Is a plug adapter a voltage converter?

No. A plug adapter only changes the plug shape and does not change the voltage.
