It sounds like a small thing.
You arrive in Lima after a ten-hour flight, you check into your hotel, you reach for your phone charger — and nothing fits.
Or you plug in your hairdryer and it lets out a loud pop, a curl of smoke, and dies forever.
Electrical problems are one of the most common and entirely preventable travel headaches. A little preparation before you leave home saves you from scrambling at an airport shop or spending your first morning in Cusco hunting for a hardware store while jet-lagged.
This guide covers everything you need to know about electricity in Peru: the outlet types, the voltage, adapters versus converters, surge protection, WiFi and internet access, SIM cards, charging on the road — and all the specific situations that arise when you’re trekking the Inca Trail or staying in a remote highland lodge.
At Machu Picchu Peru Travel, we help hundreds of travelers prepare for Peru every year. Electrical questions come up constantly — so we put together the most complete answer we know how to give.
Quick Answer: What You Need for Peru
Before diving into the details, here is the essential summary:
- Outlet types: Type A (two flat parallel prongs), Type B (two flat + one round ground), and Type C (two round prongs)
- Voltage: 220V (same as Europe, different from the US/Canada which use 110–120V)
- Frequency: 60 Hz
- Do US/Canadian travelers need an adapter? Usually no — Type A and B plugs fit directly. But pack a universal adapter to be safe.
- Do US/Canadian travelers need a converter? Only for non-dual-voltage appliances (some hairdryers, electric razors, certain chargers)
- Do European travelers need an adapter? Yes — Type C plugs fit some Peruvian outlets, but not all
- Surge protector recommended? Yes, especially outside Lima
If you remember only one thing: Peru runs on 220V. Check every device you plan to bring.
Peru Outlet Types Explained
Type A — The Most Common Outlet
Type A is the standard two-prong flat parallel outlet — exactly the same as you find throughout the United States, Canada, Mexico, and Japan.
This is the most widely available outlet type in Peru. Most hotels, hostels, restaurants, and public spaces have at least one Type A outlet accessible.
If you are traveling from the United States or Canada, your standard plugs will fit Type A outlets without any adapter at all.
Type B — The Three-Prong Option
Type B is the grounded three-prong outlet, again identical to the US standard: two flat parallel prongs plus a round grounding pin below them.
Type B outlets are found in many modern hotels, newer buildings, and upscale establishments across Peru. Any appliance with a standard US three-prong plug will fit these outlets directly.
Type C — The European-Style Outlet
Type C uses two round parallel prongs — the same plug used across most of Europe, South America, and much of Asia.
Type C outlets appear alongside Type A outlets in many Peruvian homes and older buildings. Some outlets in Peru are hybrid designs that accept both the flat Type A prongs and the round Type C prongs in the same socket — a practical response to Peru’s mixed electrical heritage.
If you are traveling from Europe, Australia, the UK, or another region with different plug types, you will need an adapter. Even if your device uses a Type C plug, the grounding and sizing standards can vary enough to cause fit issues.
The Practical Takeaway
Most travelers from North America (US and Canada) will find that their standard plugs fit Peruvian outlets without any adapter, since Type A and B are dominant.
Travelers from Europe need an adapter because while Type C outlets exist in Peru, they are not universal. You cannot rely on finding a compatible socket in every hotel room or hostel.
Travelers from the UK, Australia, South Africa, and other regions with different plug standards will definitely need a universal travel adapter.
Universal adapters — small devices that accept multiple plug types and include connectors for Type A, B, and C sockets — are the simplest solution for any traveler. They cost between $10 and $25 and eliminate all compatibility uncertainty. Buy one before you leave home.
Voltage in Peru: The Critical Factor
Peru Uses 220 Volts
This is the most important electrical fact to understand before traveling to Peru.
Peru’s electrical grid operates at 220 volts (V) — the same standard used across Europe, Australia, and most of South America.
The United States and Canada run on 110 to 120 volts — exactly half of Peru’s voltage.
This difference matters enormously. Plugging a device rated only for 110V into a 220V outlet can damage or destroy it — and in some cases cause sparks or even fire.
Dual-Voltage Devices: What’s Safe
The good news is that most modern personal electronics are dual-voltage — designed to work on both 110V and 220V.
This includes:
- Smartphones and their chargers
- Laptop computers and their chargers
- Tablets and e-readers
- Digital cameras and their chargers
- Bluetooth speakers (most modern ones)
- Electric toothbrushes (most modern ones)
- CPAP machines (most newer models)
To confirm whether your device is dual-voltage, look at the small print on the power brick or adapter. You will see something like:
Input: 100–240V, 50/60Hz
That means the device is compatible with any electrical system in the world. You may still need a plug adapter to fit the physical socket, but the voltage is handled automatically.
Single-Voltage Devices: What to Check
Some appliances — particularly those that generate heat — are often rated for only one voltage standard.
Common single-voltage items include:
- Hairdryers (the most frequent victim of voltage mismatches)
- Hair straighteners and curling irons (older models)
- Electric shavers (older models)
- Travel kettles (if bought in a 110V country)
- Some power tools
If the label on your device says Input: 110V or Input: 120V only — do not plug it into a Peruvian outlet without a voltage converter.
What Happens If You Plug In the Wrong Voltage
At best, the device simply won’t work. At worst, the motor or heating element burns out instantly, sometimes accompanied by a loud pop, smoke, or sparks.
Hairdryers are the classic example. A 110V hairdryer plugged into a 220V outlet in Peru will attempt to draw twice the power it was designed for. The result is usually immediate and permanent failure — and a very bad smell.
The fix is simple: either buy a dual-voltage hairdryer before your trip (they exist and are not expensive), or bring a voltage converter.
Adapters vs. Converters: Understanding the Difference
This is one of the most commonly confused topics in travel electricity.
What an Adapter Does
An adapter only changes the physical shape of the plug.
It allows your plug to fit into a foreign socket. It does nothing to change the electricity passing through it. The voltage coming out of a Peruvian outlet is still 220V whether you use an adapter or not.
Use an adapter when:
- Your plug is physically incompatible with the outlet
- Your device is already rated for 220V (dual-voltage)
What a Converter Does
A converter (also called a voltage converter or transformer) changes the electrical voltage itself — converting 220V from the Peruvian outlet down to 110V before it reaches your device.
Use a converter when:
- Your device is rated for 110V only
- You need to use a US hairdryer, single-voltage shaver, or similar appliance in Peru
Two-in-One Devices
The most practical solution for most travelers is a combination adapter/converter — a single unit that handles both the physical plug compatibility and the voltage conversion.
These are widely available online and at travel stores before you leave home. A quality combination device typically costs $20–$40 and handles everything in one compact unit.
Buy this before your trip, not at the airport — airport travel accessories are significantly overpriced and the selection is limited.
USB Ports and Modern Charging
One important note: most travelers today charge the majority of their devices via USB rather than direct outlet plug.
Modern USB-A and USB-C charging bricks are almost universally dual-voltage. If you are primarily charging a phone, laptop (via USB-C), wireless earbuds, and a smartwatch — you may only need a plug adapter, not a voltage converter at all.
The only situation where a converter is truly essential is when you want to use a 110V appliance (like a hairdryer or flat iron) that connects directly to the wall.
Surge Protection in Peru: Why It Matters
Power Fluctuations Are Real
Peru’s electrical infrastructure is reliable in Lima and in major hotel chains across the country — but less consistent in the Andes, smaller towns, and more remote areas.
Power outages and electrical surges occur with enough frequency that protecting your devices with a surge protector is genuinely worth doing.
An electrical surge happens when voltage spikes suddenly above the normal level. This can occur when power is restored after an outage, during storms, or due to local grid instability. A surge can damage sensitive electronics — particularly laptops, cameras, and phones — even in an instant.
Lima: Generally Stable
Lima’s electrical supply is among the most reliable in South America. The major districts of Miraflores, San Isidro, Barranco, and the historic center have consistent power with infrequent outages.
Most upscale hotels in Lima have backup generators that activate within seconds of any power interruption. You may not even notice a brief outage in these establishments.
That said, Lima does experience occasional grid fluctuations, particularly during peak summer heat when air conditioning demand strains the system. A surge protector travel adapter adds a layer of protection that costs almost nothing and potentially saves an expensive device.
Cusco: More Variable
Cusco sits at 3,400 meters in the Andes — a fundamentally different electrical environment from coastal Lima.
The city’s power supply is generally reliable for most of the year, but the wet season (November through March) brings heavier rains, lightning storms, and occasional grid disruptions. Power outages in the Cusco region during heavy rain are not uncommon, and when power returns after an outage, surges are possible.
Most good hotels in Cusco have generators, but budget accommodation and older buildings may not.
At Machu Picchu Peru Travel, we always recommend that clients traveling to Cusco pack a surge-protected adapter. Given that most travelers carry a smartphone, a laptop, and a camera — representing hundreds or thousands of dollars in electronics — the cost of protection is trivial compared to the risk.
Remote Areas and the Inca Trail
The further you travel from major cities, the more variable the electrical situation becomes.
In small Andean towns, power outages may be routine rather than exceptional. Some rural guesthouses operate on solar power or micro-hydroelectric systems that produce lower-than-standard voltages.
On the Inca Trail and other multi-day treks, there is no grid electricity at all. The campsite facilities are solar-powered at best, and charging your devices requires planning before you depart.
Charging Your Devices on the Inca Trail and in Remote Areas
This is one of the most practical questions we receive at Machu Picchu Peru Travel, and it deserves a thorough answer.
The Inca Trail: No Reliable Charging on Route
The classic 4-day Inca Trail passes through terrain that has no electrical grid access at campsites. Your guide and porter team will have lighting and cooking equipment powered by gas and batteries — not grid electricity.
Some operators provide limited solar charging for clients’ devices. Ask your operator specifically about this before departure — it varies significantly between companies.
The practical solution for most trekkers is to bring sufficient battery capacity to last the full four days without relying on any charging.
Recommended approach:
- Charge all devices fully the night before departure
- Bring a high-capacity power bank (20,000 mAh or larger for four days)
- Keep your power bank warm at night — battery capacity drops significantly in cold temperatures
- Minimize screen-on time and lower your phone’s brightness to extend battery life
- Put your phone in airplane mode when not needed to conserve battery dramatically
- Bring spare batteries for any devices (headlamp, GPS, etc.) that use them
Power Banks: The Essential Trekking Accessory
A high-quality power bank is the single most important charging accessory for anyone trekking in Peru.
What to look for:
- Capacity: 20,000 mAh is sufficient to charge a smartphone approximately 4–5 times. For a 4-day trek with photos, maps, and music, this is a realistic minimum.
- Multiple outputs: Choose a power bank with USB-A and USB-C ports to charge different devices simultaneously.
- Weight: Power banks add weight to your daypack. A 20,000 mAh unit typically weighs 400–500 grams — worth it for the convenience.
- Temperature rating: Standard power banks work at temperatures down to about 0°C. The Inca Trail can drop to -5°C or lower at higher camps. Store your power bank inside your sleeping bag at night to prevent cold-related capacity loss.
- Airline approval: Most airlines permit power banks up to 100Wh (approximately 27,000 mAh at 3.7V) in carry-on luggage. Power banks are not permitted in checked luggage. Check your specific airline’s current rules.
The Short Inca Trail and Train Options
For travelers using the 2-day Inca Trail or arriving at Machu Picchu by train, charging is much more manageable.
Aguas Calientes (the town at the base of Machu Picchu) has reliable electricity and hotels with standard outlets and good WiFi. Most hotels will let you charge devices during the day even outside of your room hours if you ask.
Salkantay Trek Charging
The Salkantay Trek passes through a mix of remote camping areas and small mountain lodges. In the lodge-based version of the trek (staying in warm accommodations each night rather than tents), some charging is available at each stop. In the camping version, similar power bank strategy to the Inca Trail applies.
WiFi and Internet Access in Peru
Staying connected is a priority for most modern travelers, and Peru’s internet infrastructure — while uneven across the country — is genuinely good in major tourist areas.
WiFi in Lima
Lima has excellent WiFi coverage across hotels, restaurants, cafés, and many public spaces.
The Miraflores and Barranco districts, which host most international visitors, have particularly reliable and fast internet. Cafés in these areas typically offer free WiFi with speeds sufficient for video calls and streaming. The major hotel chains in Lima have strong, hotel-wide WiFi networks.
For serious remote work, Lima’s coworking spaces offer high-speed dedicated connections and professional environments.
WiFi in Cusco
Cusco has good WiFi coverage in its main tourist areas — the Plaza de Armas, San Blas neighborhood, and the main streets around them.
Hotel WiFi quality in Cusco varies significantly between properties. Top-tier hotels have reliable high-speed connections. Budget accommodation can be patchy, particularly in older buildings where the physical infrastructure limits bandwidth.
Speeds in Cusco are generally lower than Lima — sufficient for email, messaging, and social media, but sometimes unreliable for video streaming or video calls.
WiFi in the Sacred Valley and Remote Areas
WiFi availability drops significantly outside major cities.
Most hotels and lodges in the Sacred Valley (Ollantaytambo, Urubamba, Pisac) offer WiFi, but speeds can be limited. Some luxury properties have invested in satellite internet and offer surprisingly good connections. Budget accommodation may have intermittent service.
Once you’re in truly remote areas — trekking routes, rural villages, Inca Trail campsites — there is generally no WiFi at all.
Mobile Data: The Best Backup Solution
For reliable connectivity throughout your Peru trip, a local SIM card with a data plan is the most practical and cost-effective solution.
Peru has three main mobile operators: Claro, Movistar, and Entel. All three offer prepaid tourist SIM cards with data plans available at airports, phone stores, and supermarkets throughout the country.
Current typical packages (verify at time of purchase as prices change):
- Claro and Entel both offer 30-day tourist plans with several gigabytes of data for approximately $10–$20 USD
- Coverage is excellent in Lima and Cusco and in most towns along the main tourist routes
- Coverage is limited or absent on remote trekking routes, in the Amazon, and in high mountain areas
Steps to get a local SIM:
- Bring an unlocked phone — confirm this with your carrier before departure
- Purchase a SIM at the airport arrivals hall in Lima (Claro, Entel, and Movistar all have airport kiosks)
- Choose a prepaid plan that matches your expected data usage
- Activate on arrival and top up as needed at supermarkets and phone stores throughout Peru
If you prefer not to deal with a local SIM, international roaming packages from your home carrier are an alternative — though typically more expensive for the same data volume.
WhatsApp: The Communication Standard in Peru
One practical note for communicating with local services in Peru: WhatsApp is the standard communication tool for hotels, restaurants, tour operators, and guides throughout the country.
Text messages and phone calls are less commonly used for business communication in Peru. If you are contacting a local restaurant for a reservation, confirming a guide booking, or communicating with your hotel about early check-in, WhatsApp is the most effective channel.
Having a local SIM or international data roaming enables WhatsApp communication and makes every logistics interaction in Peru significantly easier.
Device-Specific Guidance for Peru
Smartphones
Modern smartphones are universally dual-voltage and will charge safely from any Peruvian outlet with the correct plug adapter.
Specific recommendations:
- Download offline maps before arrival (Google Maps, Maps.me, or Gaia GPS for trekking)
- Download your translation app (Google Translate with Spanish downloaded offline)
- Screenshot your hotel addresses, confirmation numbers, and tour booking details — internet is not always available when you need it most
- Enable airplane mode in the mountains to preserve battery and use saved offline content
Cameras and Photography Equipment
Camera chargers (both DSLRs and mirrorless systems) are almost always dual-voltage. Verify the label, but expect compatibility.
Practical tips for photographers in Peru:
- Bring extra batteries rather than relying on in-the-field charging
- Cold temperatures at altitude reduce battery life significantly — keep spare batteries in a chest pocket or sleeping bag
- A power bank with USB-C output can charge many modern camera batteries via USB
- Memory cards are available in Lima and Cusco but may be overpriced — bring sufficient storage from home
Laptops
All modern laptop chargers are dual-voltage. Verify the brick label but expect a range of 100–240V.
A laptop is useful for extended Peru trips but adds weight. For shorter trips, a tablet or smartphone with a keyboard case may be a lighter alternative.
CPAP and Medical Equipment
If you use a CPAP machine for sleep apnea, the good news is that most modern CPAP devices are dual-voltage. Verify your specific machine before departure.
The more significant concern at altitude is that standard CPAP pressure settings may need adjustment, as the lower air density at Cusco’s 3,400m elevation affects how the machine delivers air. Consult your sleep specialist before traveling to high-altitude Peru destinations.
Also note: altitude itself disrupts sleep patterns. Many travelers experience fragmented sleep in Cusco during the first few nights regardless of CPAP use.
Electric Shavers
Older electric shavers may be single-voltage (110V only). Modern shavers — especially from major brands like Braun, Philips, and Panasonic — are almost universally dual-voltage.
Check the input label. If it shows 110V only, either use a converter or consider switching to a manual razor for the duration of your trip.
Hairdryers and Styling Tools
This is where most electrical problems occur in Peru.
The safest solutions:
- Buy a dual-voltage travel hairdryer before your trip. These are compact, lightweight, and designed specifically for international travel. Brands like Conair, Remington, and BaByliss offer good options at $20–$40.
- Use your hotel’s hairdryer. Most hotels in Peru — from budget to luxury — provide hairdryers in the bathroom. These are local appliances rated for 220V and will work perfectly. Ask the front desk if one is not visible in your room.
- Bring a converter. If you must use your existing 110V hairdryer, a voltage converter rated for high-wattage appliances (hairdryers typically draw 1000–2000W) will protect it.
Where to Buy Adapters and Converters in Peru
If you arrive without the right adapter or converter, here is where to find them.
Lima Airport (Jorge Chávez International)
The arrivals hall of Lima’s international airport has several retail shops that carry basic travel accessories including adapters. Expect to pay more than you would at home — airport prices throughout the world are elevated, and Lima is no exception.
That said, if you have nothing and need something urgently, the airport shops will solve the immediate problem.
Lima City: Electronics and Hardware Stores
In Lima, the best places to buy adapters, converters, and power accessories are:
Electronics stores: Stores like Hiraoka, Oeschle, and Ripley in Lima’s Miraflores and San Isidro districts carry a range of travel accessories at fair prices.
Ferreterías (hardware stores): These local hardware stores, found on virtually every commercial street in Lima, sell basic adapters at very low prices. Ask for a “adaptador de enchufe” or “convertidor de voltaje”. Quality varies, but for a short-term solution they work fine.
Shopping malls: Malls like Larcomar in Miraflores and Jockey Plaza in Surco have electronics sections and international accessory shops.
Cusco City
In Cusco, electronics and travel accessories are available in:
- The electronics stores on Avenida El Sol and surrounding streets
- Ferreterías throughout the city center
- Some shops in the San Pedro market area
Quality in Cusco shops can be inconsistent. If you can solve the problem before leaving Lima, do so there.
What to Avoid
Avoid buying cheap no-name adapters or converters from street vendors. These products are often not properly grounded, may not handle the stated voltage, and in some cases can be genuinely dangerous. Spend a few more soles and buy from a proper electronics or hardware store.

Tips from Our Team at Machu Picchu Peru Travel
After years of helping travelers prepare for Peru, our team at Machu Picchu Peru Travel has a few hard-earned recommendations:
Buy your adapter before you leave home. The selection is better, the prices are lower, and you’ll have time to test it with your devices before you need it. A $15 universal adapter from an electronics shop near you is better than a $40 airport option bought in a panic.
Do the voltage check two weeks before departure. Go through every electronic item you plan to bring. Look at every power brick. Write down anything that says 110V only. Solve those problems before packing.
A power bank is not optional for trekkers. Whether you’re doing the Inca Trail, the Salkantay Trek, or a day hike to Rainbow Mountain, not having sufficient battery is a genuine problem — cameras, navigation apps, and communication all depend on charged devices. We build power bank reminders into our pre-departure preparation checklist for every trekking client.
WhatsApp before you land. Make sure you can access WhatsApp before you arrive in Peru. It is the primary communication tool for every hotel, restaurant, guide, and driver you will interact with. If your home plan doesn’t support data roaming cheaply, get a local SIM at Lima airport as your first stop after customs.
Protect your laptop with a surge protector strip. If you’re traveling with a laptop for work or photography editing, a compact surge-protected power strip lets you charge multiple devices safely from a single outlet — particularly useful in rooms where outlets are scarce.
Frequently Asked Questions
Do I need a voltage converter for my iPhone in Peru? No. iPhone chargers are dual-voltage (100–240V). You may need a plug adapter if your charger has a US plug and you encounter Type C outlets, but no voltage conversion is required.
Can I use my electric razor in Peru? Most modern electric razors are dual-voltage. Check the label on the charger or the razor itself. If it says 100–240V, you need only an adapter. If it says 110V only, use a converter.
My hotel says it has 110V outlets. Is this possible? Some upscale international hotels in Lima and Cusco install 110V outlets in rooms specifically for guests from North America. These are typically labeled and placed alongside standard 220V outlets. Always verify which outlet is which before plugging in — and when in doubt, check with the front desk.
Is it safe to leave my phone charging overnight in Peru? Yes, with appropriate precautions. Use your original manufacturer charger or a quality aftermarket one. A surge-protected adapter adds an extra layer of protection. Don’t leave charging devices on a bed or soft surface overnight.
Can I charge my power bank on the Inca Trail? There is no reliable charging available at Inca Trail campsites. Some trekking operators provide limited solar charging, but you cannot depend on it. Arrive at the trailhead with all devices and power banks fully charged.
What if I forget my adapter? Pick one up at Jorge Chávez International Airport in Lima upon arrival. They are available at electronics and travel shops in the arrivals hall. Alternatively, most hardware stores (ferreterías) near any hotel in Lima or Cusco carry basic adapters at very reasonable prices.
Final Thoughts
Peru’s electrical system is simple once you understand its two key facts: three outlet types (mostly A and B, some C) and 220V power.
For most travelers from the United States and Canada, the main precaution is checking appliances for voltage compatibility — particularly hairdryers and styling tools. A universal adapter and a power bank round out the preparation.
For European and other travelers, add a physical adapter to the list.
For trekkers on the Inca Trail or other multi-day routes, power bank capacity becomes the central consideration. Plan ahead, charge fully, and keep your devices warm at altitude.
None of this is complicated. A few minutes of preparation at home eliminates every electrical problem you might otherwise encounter on the road.
