Power adapter for Peru: plugs and voltage
What plug and voltage Peru uses, whether you need an adapter or a converter, and what to bring.

Do you need a power adapter for Peru?
It depends on the plugs you use at home. Where do you live?
Peru uses plug types A, C, and your plugs from the United States fit the main sockets, so you probably do not need a plug adapter. Sockets can vary, especially in older buildings, so check if you are unsure.
The voltage here is 220V, different from 120V at home. Check the label on each device. If it lists a range that includes 220V, such as 100-240V, a plug adapter is enough. If it does not, as with some hair dryers and curling irons, you would need a voltage converter, or leave it at home.
Electricity in Peru
- Plug types
- A, C
- Voltage
- 220V

- 60Hz
What the plugs look like
Type A: two flat parallel pins.
Type C: two round pins, often called the Europlug.
These are the main plug types. Sockets can vary between buildings, especially older ones. For the official list, see the IEC, World Plugs.
Good to know in Peru
Peru uses Type A (two flat parallel blades) and Type C (two round pins) plugs. Many Peruvian outlets are hybrid sockets that accept both. Here is the trap that damages equipment: US-shaped Type A plugs physically fit into many Peruvian sockets, so US travelers often need NO adapter: but the voltage is 220V, not the US standard of 120V. Plugging in a 120V-only device without a step-down converter will destroy it and may cause a fire or electrical shock. ALWAYS check your device's power label before plugging in. If the label says 'INPUT: 100–240V, 50/60Hz': it is dual-voltage and safe to use anywhere, just plug it in (or use a cheap Type C adapter if needed). If the label says 'INPUT: 120V only': you need a step-down voltage converter regardless of plug shape. Most modern phone chargers, laptop power bricks, and camera chargers are dual-voltage. Many US hair dryers, curling irons, and flat irons are 120V-only: either buy dual-voltage versions before travel or purchase a heavy-duty converter. Some upscale hotel bathrooms provide a 110V shaver outlet: check the label on the outlet before using it.
Adapter or converter?
An adapter only changes the shape of the plug so it fits the socket. A converter also changes the voltage. Most phone, tablet and laptop chargers handle different voltages on their own, so for those you only need an adapter. Check the label on each charger for a range such as 100-240V.
What to bring
One adapter with several USB ports can charge your phone, tablet and earbuds together. Check that the one you choose fits plug types A, C.

Common questions
What is the difference between an adapter and a converter?
An adapter only changes the shape of the plug so it fits the socket. A converter also changes the voltage. Most phone and laptop chargers handle different voltages themselves, so they only need an adapter.
How do I know if my device can handle the voltage?
Look at the small print on the charger or the back of the device. If it lists a range that includes the voltage in Peru, such as 100-240V, it will work with just a plug adapter. If it lists one number that does not match, you would need a converter.
Can I bring my hair dryer?
Hair dryers and other heating tools often work at only one voltage, so check the label first. If it does not cover the local voltage, using it can damage it or be unsafe. Many hotels have hair dryers, so it can be easier to leave yours at home.
Do I need one adapter per device?
No. One adapter with several USB ports can charge a phone, tablet and earbuds at once. Make sure it fits the plug type used where you are going.
