United States of America to Singapore
The United States of America to Singapore route is electrically incompatible. Different plug types and 110V voltage difference.
Need an Adapter?
Yes! Yes, you need a Type A/B to Type G adapter
Need a Voltage Converter?
Yes — 230V can damage single-voltage United States of America devices
🔍 Why This Route Matters
United States of America and Singapore represent two distinct electrical worlds. Here's what you need to know before you go. Type A/B (United States of America) and Type G (Singapore) are fundamentally different plug shapes. More critically, United States of America's 120V power won't match Singapore's 230V system. That's a 110 volt gap that matters. National dish: http://commons.wikimedia.org/wiki/Special:FilePath/Empty%20Singapore-Malaysia%20Causeway.jpg. Getting it right means one less thing to worry about when you land.
Side-by-Side Comparison ⚡
🎯 What Locals Know (That Tourists Don't)
- ✦Uses 12H time format (e.g., 11:00 PM)
- ✦Temperature measured in Celsius (°C)
- ✦Electrical system uses 230V at 50Hz with Type G plugs
- ✦Tap water safety: drinkable
- ✦Check if your hotel has universal outlets in rooms (increasingly common in newer properties)
- ✦When in doubt, look for "INPUT: 100-240V" on your device. That means it's safe without a converter.
What You Need for This Trip 🧳
Plug Adapter
RequiredUnited States of America's Type A/B plugs won't fit Singapore's Type G outlets.
Voltage Converter
May Be RequiredSingapore uses 230V vs United States of America's 120V. Most modern electronics handle this automatically.
Airport & Arrival Tip
SIN is your first stop, and potentially your first charging opportunity. Look for dedicated device charging kiosks in the arrivals hall (some require payment, others are free). Some airports have vending machines with travel essentials including adapters. Worth checking before heading to stores. Many ride-share drivers have USB chargers available. Don't hesitate to ask. Check into your hotel/Airbnb first before exploring. Test your adapters and charge devices fully.
Packing Advice
Pack both a plug adapter (Type A/B to Type G) AND a voltage converter (120V to 230V). You'll need both. Look for adapters with surge protection. Cheap ones can fail and damage devices. High-capacity power banks (20,000+ mAh) are worth the weight if you're a heavy device user. Label your cables with colored tape or tags. Hotels have lost luggage full of identical black cables. Hair dryers are heavy and voltage-sensitive. Hotels in Singapore almost always provide them. One adapter per person is cutting it close. Bring at least two in case one fails.
Seasonal Considerations
Time of year matters for power planning in Singapore, especially if you're visiting during temperature extremes. **Summer travel:** Peak tourist season = crowded outlets at cafes and attractions. Charge at off-hours. **Winter travel:** Shorter days mean more screen-on time for navigation and entertainment. Plan accordingly. **Rainy season:** High humidity can cause corrosion on plug contacts. Pack electronics in waterproof pouches. **Holiday season:** Festive season shopping requires full phone battery for photos, maps, and payment apps. Seasonal extremes (hot summers, cold winters) impact battery performance more than most travelers expect.
