Voltage & Frequency: Mexico operates on 125V, 60Hz electrical system. North American appliances work directly. European appliances require step-down transformer.
Plug Types: Mexico primarily uses two-prong flat parallel plugs (Type A) identical to US standard. Some establishments have three-prong grounded outlets (Type B).
Adapters & Converters: US travelers need no adapter. UK/EU/Australian travelers need Type A/B adapter. Step-down transformer required for 220V appliances. Dual-voltage devices (many modern electronics) work with just an adapter.
Availability: Adapters and converters available at airport, hotels, and electronics stores. Recommend bringing from home for compatibility and cost savings. USB power banks useful for charging devices on-the-go.
Safety: Mexican outlets generally safe but facilities older than North American standards. Use surge protectors for valuable electronics. Hotel staff can facilitate charging if adapters unavailable.
