Do you need an adapter?
The Iceland outlet situation
Iceland uses Type C (two round pins) and Type F (two round pins with side ground clips) outlets, at 230V / 50Hz. Both types accept each other — Iceland has a hybrid system. Standard European 2-pin plugs work directly. Type A/B (US-style flat pins) need an adapter.
Voltage is the bigger concern: 230V vs the US 120V will fry a non-dual-voltage device. Most modern electronics (laptop, phone, camera chargers) are dual voltage — they automatically accept 100–240V. Check the small print on the charger: if it says "Input: 100–240V", you're fine. If it says "120V", you need a step-down transformer.
FAQ
Do I need a power converter?
Probably not. Most modern devices are dual voltage. The only exception is older high-power appliances (hair dryers, curling irons from before 2000). If you bring a US hair dryer, it'll fry.
Is USB charging reliable in Iceland?
Yes — hotels, guesthouses, and most cafés have outlets you can use. USB ports are common in newer hotels but not universal. Bring a small power strip if you have multiple devices.
Campsite power?
Most organised campsites have electrical outlets at specific sites (often ISK 500–1,000 extra). Most don't include power at every tent pitch. Bring a power bank if you camp often.
