Check the actual nameplate of your American 120 Volt gadgets he brings with him.
Some SMPS cover the whole range e.g. 90 - 270 Volts 50/60 Hz.
If not you need a 240 - 120 stepdown transformer, if it is small chargers etc. probably 30 VA will do.
A lot of travel adaptors only change pin positions and don't change voltage.

The bottom symbole is a flat pin, I used the I symbol to visualise it.
