Plug shape, voltage, frequency — the four things that decide whether your gear works on this route.
What to pack for this route.
One adapter for the plug shape, one converter when voltage bands cross. That covers most of what you need.
A universal adapter covers this route plus 150+ other countries.
Bands differ (230V vs 100V). Hair dryers, curling irons, kettles need a converter — or a dual-voltage replacement.
