From Montenegro to United States
When travelling from Montenegro to United States: None of your Montenegro plug types fit in United States. You will need a travel adapter. Voltage is different (230V → 120V). Check your charger label; if it doesn’t list 120V you’ll also need a voltage converter. Frequency differs (50Hz → 60Hz). Modern phone and laptop chargers are usually fine, but some clocks, motors, and appliances may behave incorrectly.

About electricity in United States
The United States uses 120V/60Hz with Type A and B sockets.
Grid & history
The US grid is a federation of three large interconnections (East, West, Texas) built up through the 20th century. The mix is shifting fast: gas dominates, coal is in decline, and wind and solar are now the largest sources of new capacity.
Availability
Very reliable in cities; rural areas and storm-prone regions (Gulf Coast, Florida, California fire season) vary.
Sockets & hotels
Two flat blades (Type A) for ungrounded outlets, grounded Type B in most modern buildings. Older properties may have only Type A.
Energy mix
Natural gas is the largest source; coal is in steep decline.
Practical tips
- Most US plugs are unpolarised Type A; modern grounded ones are Type B.
- Voltage is 120V. European 230V-only heaters and hair dryers do not work here without a converter.
