When you bring your own electric device in the USA, you’ll need an adaptor and a converter. In the US most of the plugs have two flat blades, even if nowadays you can find also plugs with a further round pin, the one for the grounding. It is important to remember that wall sockets in US houses provide 110 Volts and 60 Hz of power. Just big electric appliance such as dryers or stoves use sockets with 220V. Most of the electric devices (notebooks, tablets…) have charger that can be used from 100V to 240V, so you won’t need to buy a converter. (How to check if your device can be used in the US? You should find this “input: 110 - 240v / 50 - 60Hz” written on it.) Please note that the charge time may be longer. If you plan to stay in the US for a period of time, it may be more convenient to buy some new electric devices (e.g. hairdryer or electric razor), that can be found for a value price in a lot of stores.
