Voltage: 220V, 50Hz AC standard throughout France. North American 110V/120V devices require step-down converter for continued operation. UK 230V devices compatible (minor voltage variance handled by voltage regulators in modern electronics).
Plug Types: France exclusively uses Type E (French) and Type C (Europlug) standards. Type E features two round holes with grounding pin. Type C (Europlug) has two round holes without grounding. Adapters required for US, UK, Australian, and other plugs not matching European standards.
Adapter Recommendations: Portable dual-voltage universal adapters handle multiple plug types. Purchase before travel or at airport (limited selection). Hotels may lend adapters (request at front desk). Electronics shops in city sell adapters though prices higher than pre-travel purchase.
Phone & Device Charging: Most modern smartphones, tablets, and laptops include automatic voltage conversion (check device charger for 100-240V marking). USB charging ports increasingly common in hotels. Portable battery packs provide backup charging. Bring USB-C and Lightning cables as multiple charging standards common.
Power Outlets in Accommodations: Budget hotels may offer limited outlets. Bring power strips with multiple sockets for convenience. Apartments/Airbnb typically have more outlets than hotel rooms. Bathroom outlets usually limited (designed for razors only).
Grounding & Safety: Modern outlets grounded. Older buildings may have ungrounded outlets. Ungrounded adapter use not recommended for high-power devices. Check outlet condition before plugging in expensive electronics.
