Voltage: Armenia uses 230 volts AC, 50 Hz frequency.
Plug Types: European standard Type C (two round pins) and Type F (two round pins with earth clips). Some older buildings may have Type D (three round pins in triangular pattern).
Adapters: Essential if your devices use different plugs (US Type A, UK Type G). Universal adapters work but dedicated European adapters more reliable. Available in pharmacies and electronics shops.
Power Supply: Generally reliable in main city areas. Occasional outages in outlying areas. Most hotels provide backup power or generators.
Charging: Hotels usually offer USB charging stations. Bring portable power bank for full days of sightseeing. Internet cafes often allow device charging.
Water & Climate Considerations: High altitude (1,430m) means thinner air and intense sun. Drink water frequently. Electronic devices may behave differently due to altitude and temperature changes.
