Which Countries Use 110V Power? (2026 Global Voltage Guide)

Countries using 110V–130V power are primarily concentrated in North America, parts of South America, and specific regions in Asia.

Here is a breakdown of the regions and countries using this voltage standard:

1. North America

This is the core region for the 110V–120V standard.

• United States

• Canada

• Mexico

2. Central America & The Caribbean

Most countries in this region follow the North American standard due to historical trade and infrastructure links.

• Costa Rica, Panama, Guatemala, Honduras, El Salvador, Nicaragua.

• The Bahamas, Cuba, Dominican Republic, Jamaica, Puerto Rico.

3. South America (Selected Countries)

South America is a “mixed” continent; you must be careful here as standards vary by country.

• Colombia, Ecuador, Venezuela: Primarily 110V–120V.

• Brazil: A unique case. Major cities like Rio de Janeiro and São Paulo use 110V/127V, while the capital (Brasilia) and northern regions often use 220V.

• Suriname and Guyana.

4. Asia

• Japan: Uses 100V (the lowest in the world). It also has a split frequency: 50Hz in the East (Tokyo) and 60Hz in the West (Osaka).

• Taiwan: Uses 110V.

Quick Reference Table for Business Strategy

If you are exporting high-power equipment like Portable Power Stations or Solar Security Systems, pay close attention to these technical specs:

 Pro Tips for Manufacturers

• Input Tolerance: Most “110V” devices are designed to handle a range, typically 100V to 130V.

• The 50Hz vs. 60Hz Trap: While many modern switching power supplies handle both, heavy-duty motors (like those in AC units or large pumps) are sensitive to frequency. Selling a 50Hz motor in the USA (60Hz) will cause it to run too fast and potentially overheat.

• Global Compatibility: If you are targeting these markets via your independent site, ensure your product listings explicitly state “US Standard 110V/60Hz” to avoid high return rates from customers in 220V regions.
