How Does Electricity & Plugs Work in Argentina?
Last verified: 2025-06 · Americas
1The Quick Answer
Argentina uses a unique Type I plug (three flat pins in a triangle shape) at 220V/50Hz — most visitors need a specific adapter.
2What You Need to Know
Argentina's Type I plug is unique to Argentina, Uruguay, and a few other South American countries — it features three flat pins arranged in a triangle and is not the same as the Australian Type I or any European plug. The voltage is 220V at 50Hz, so devices designed for 110V (common in North America) will need a voltage converter unless they are dual-voltage (check the device label). Universal travel adapters with Type I compatibility are available at hardware stores (ferreterías) in Argentina and at most international airport shops. Many modern hotels provide universal sockets in bathrooms.
3Practical Tips
Practical Tips
- 1Buy a universal travel adapter that specifically lists 'Type I Argentina' support before you travel — not all universal adapters include it.
- 2Check your device chargers for '100–240V' input — most modern phones, laptops, and cameras are dual-voltage and only need the adapter, not a converter.
- 3If you forget an adapter, ferretería (hardware) stores in any Argentine town stock them cheaply.
Important Warning
Plugging a 110V-only device (some US hairdryers, older appliances) directly into an Argentine socket without a voltage converter will destroy the device and may cause a fire.
How does this compare?
Electricity & Plugs rules in nearby and similar countries:
Mexico uses Type A and B plugs at 127V/60Hz — identical to the USA and Canada, so North Americans need no adapter whatsoever.
Brazil uses Type N plugs (two round pins plus a grounding pin) as its national standard, but voltage varies by city — São Paulo and Rio are 127V while many other cities are 220V.
Canada uses Type A and Type B plugs (same as the USA) at 120V/60Hz — North American devices work perfectly; European and UK devices need an adapter and possibly a voltage converter.
