Power plugs and plug adapters bridge equipment to outlets it was not born to fit: international travel adapters that let laptops and chargers work abroad, universal plug adapters for equipment arriving with foreign plugs, and the replacement and conversion plugs that put the right connector on the right cord. For traveling staff and internationally sourced equipment, they are the small part the whole trip depends on.
Know what an adapter does and does not do: it changes the plug shape, not the voltage - the device's own power supply must accept the destination voltage, which nearly all modern IT power bricks do but plenty of other equipment does not. Check the adapter covers the destination countries' outlet types, and prefer grounded adapters for grounded equipment. For frequent travelers, issuing a standard adapter kit beats airport purchases every time.
