Voltage & Frequency: 110 volts, 60 Hz (same as USA and Canada).
Plug Types: Type A plugs (two flat parallel pins) standard, matching USA outlets. Type B (with grounding pin) also common in modern buildings.
Adapters Needed: If arriving from Europe, UK, Australia, or Asia, bring adapters. USA and Canadian devices work directly without adapters. Dual voltage devices (common for phones, laptops, camera chargers) work fine.
Power Reliability: Generally reliable in Santo Domingo with occasional outages, especially during storms. Hotels and major establishments have backup generators. Water pressure sometimes affected by power outages.
What to Bring: Surge protector for multiple devices (voltage fluctuations possible). Phone chargers are most essential. Laptop power adapter if not dual voltage. Flashlight/headlamp useful during occasional outages.
Purchasing Locally: Electronics shops throughout Santo Domingo sell adapters, chargers, and power strips at reasonable prices. However, hotel front desk can often provide adapters for guest use.
