USB-C chargers for travel: power, cables and mains compatibility

One USB-C charger can replace several travel chargers. It still needs the right input voltage, enough USB-C power and a cable that supports the device.

In brief

  • ✓Check INPUT 100–240 V and 50/60 Hz.
  • ✓Check the charger's USB Power Delivery wattage.
  • ✓Use a cable rated for the required power.

Mains input still comes first

A USB-C output does not prove worldwide input compatibility. Read the INPUT line on the charger. Many reputable laptop and phone chargers support 100–240 V, but this must be confirmed on the specific model.

USB Power Delivery

USB Power Delivery allows devices and chargers to negotiate voltage and current. The maximum capability of the standard does not mean every charger or cable supports that level.

A sensible travel setup

  • ✓One reputable multi-port charger with a wide INPUT range
  • ✓A country adapter that preserves earth if the charger requires it
  • ✓Correctly rated USB-C cables
  • ✓A small spare charger for essential devices
