Works as either plug adaptor or transformer. Pretty much all-in-one device. Can adapt to/from all major plug configurations.
Generally, you do not need a transformer if your device has a transformer plug with it - but not always the case. I fried a Plantronics Bluetooth earpiece twice by just using a plug adaptor.
Good advice to have an all-in-one device. But this particular one says not for use with battery chargers. We travel with a small converter, bought many years ago from Sharper Image, that has all the plugs you'll need plus a converter that works for batteries, blow dryers, heating pads, etc. Try Magellan's, Travel Smith or another device at Brookstone.
