Updated on

With world-famous beaches, legendary nightlife, and centuries of history and culture, it’s not hard to see why Thailand is one of the world’s top travel destinations.

But! The Thai power system is unique and you don’t want to risk your devices breaking due to an incompatible or low-quality power adapter, or a power surge that is not supported by a trusty fuse protector. Use this quick guide to learn the basics and ensure you can charge everything while you’re in Thailand! We’ll also cover some necessary additions to your packing list and common FAQs.

See our product selection criteria and guidelines here.

Which power outlets do they use in Thailand?

The four different types of electrical outlets are used in Thailand. Type A and B, which are the two outlet types found in the U.S., are both used there; the only difference between the two is that Type A sockets are ungrounded, while Type B has a round grounding plug. Type C sockets, which have two round holes and are commonly used in Europe, are also found in Thailand. Lastly, there are Type O outlets, which are used exclusively in Thailand.

They have two round holes and a third slightly larger grounding hole; even though these sockets don’t exist elsewhere, they’re compatible with any of the two-pronged European plug types.

The good news is the outlets that are most common in Thailand, both in Bangkok and throughout the country, are actually multi-type sockets that can accommodate each plug type. Unlike the U.S., and like most other countries – Thailand’s electrical grid uses a frequency of 50 Hz and a voltage of 220V.

What kind of power adapter do I need for Thailand?

A common question most travelers ask is, “What plug do I need for Thailand?” Because many of the electrical outlets found in Thailand are multi-type, you won’t always need an adapter. However, you may also encounter Type C or Type O sockets that can only accommodate the plug type with two round pins.

Your safest bet is to bring a Universal Adapter that will have you covered no matter what type of plug you encounter as you travel through Thailand.

This one is our favorite because it works in 100+ countries so you can use it on all your future travels. It also has a built-in fuse protector in case of a power surge AND it comes with a lifetime replacement guarantee. This helps us trust the quality and ours has never failed us in dozens of countries. Knowing it will be replaced if an issue occurs (so we don’t have to ever buy another power adapter) is a huge bonus for us!

Other Thailand Packing List Items

In addition to your US-to-Thailand power adapter, these items will help you pack with intention and expand the possibilities of your getaway. Also, check out our Thailand packing list for more inspiration and ideas.

  • 1. Neck Wallet / Passport Pouch

    Pickpocketing is unfortunately fairly common in crowded touristy areas, especially in Bangkok. To protect your valuables, keep them in a wallet around your neck instead of in your pocket or bag; they’ll be much less likely to be stolen this way since you won’t be flashing your wallet repeatedly or leaving it exposed in your back pocket. It also has RFID-blocking material to protect all the items it will keep organized (cash, credit cards, passports, travel documents, phones, etc.)

  • 2. Jet lag Relief

    Thailand is 11 hours ahead of the East Coast of the U.S., which means jet lag is almost inevitable. Not to mention the drastic time change! Bring some jet lag relief pills to help you cope with the time difference, or you might find yourself falling asleep before dinner. It will also help you become quickly acclimated on the return trip.

  • 3. Virtual Private Network (VPN)

    Thailand has suffered a growing number of data breaches and hacking in recent years. To protect yourself against cyberattacks (in the nation that tops ALL other SE Asian countries for phishing attacks) – you’ll need a VPN.

    A Virtual Private Network will protect you when joining random Wi-Fi networks at coffee shops, cafes, airports, and more. I even learned that your hotel or Airbnb is not safe when my credit card number was stolen on vacation.

    We use NordVPN because they are affordable and offer the fastest streaming with unlimited bandwidth. A VPN protects you with 1-click from losing your passwords, credit cards, and private identity. Also, it will free you up from popular websites that may be blocked or censored in Thailand. If you’re planning to stay connected (for work needs, free internet surfing, or to stream your favorite shows via Netflix, HBO, Hulu, or live TV) – a VPN is the best all-in-one solution.

  • 4. Lipstick-Sized Portable Charger

    You’ll probably use your phone frequently in Thailand to take photos, use maps, call a Grab, or just stay in touch with people at home. You’ll want to be absolutely sure the battery won’t die while you’re out, so bring a small portable charger to juice it up during the day. You can throw it in your backpack with any electronic and it will charge while you’re on-the-move!

  • 5. Windproof Travel Umbrella

    It rains in Thailand throughout the year but can be especially heavy during the rainy season from May to early November. During the rainy season, it often rains over 8 inches per month, so it’s best to be prepared with a reliable, compact travel umbrella that you can easily throw in your daypack. The one we recommend even comes with a zip case that keeps your other items dry when storing your wet umbrella.

  • 6. Travel Insurance for Thailand

    Thailand is not the kind of place to risk your coverage. As an unpredictable and unique destination, you’ll want to be protected in case of unforeseen circumstances. Not to mention, your domestic provider does not cover you overseas (including Medicare and Medicaid). Travel insurance will protect you for common travel issues like baggage loss, theft, flight delays, cancelations, medical transfers, and international hospital bills.

    We use Faye because they are upgrading the entire industry. As the first all-digital provider, they handle everything from claims to reimbursements through their mobile app. They helped me contact my doctor while overseas and advised me to the nearest clinic through their 24/7 customer support. With plans to cancel your trip “for any reason,” they are the best provider we’ve worked with and we can’t recommend them enough!

  • 7. Quick-Dry Travel Towel

    A travel towel is a must-have for Thailand. You never know if your accommodation will have a towel (or if it will be up to your cleanliness standards), and this one is very compact. It’s thin but absorbent microfiber material dries 10x faster than cotton and is way more practical for hikes and beach days than a big, fluffy one.

  • 8. High-Quality Filtered Water Bottle

    The water system in Thailand is not considered potable or safe to drink. It is a humid environment and you will need to stay hydrated, so purchase a filtered water bottle to ensure you aren’t wasting all your money on plastic ones. Especially for excursions, in the countryside, and times when no other water sources will be available, this will be crucial.

    This Grayl bottle is our go-to because it’s a literal lifesaver that removes bacteria, pathogens, parasites, viruses, microplastics, pesticides, and more. It’s a little pricey but way cheaper than going to the hospital for E. coli or Hepatitis A.

  • 9. Hanging Toiletry Bag

    Bathrooms do not always come equipped with enough storage, and the ones in Thailand can range from luxurious to slightly unhygienic. This hanging toiletry bag creates a built-in shelf no matter where you roam. It has 4 giant pockets that can hold all of your toiletries, makeup, washcloths, medicine, etc., plus 3 external compartments for smaller items like jewelry.

    This one by Eco Sun puts all other toiletry bags to shame! It’s designed by travelers who know what jet-setters really need for long and short getaways. Even when you have plenty of countertop space, keeping everything organized is better than sprawling your products all over the hotel room. And it makes repacking a breeze. Just get it, you won’t regret it 🙂

  • 10. Activated Charcoal

    Thailand is not a place I would venture to without activated charcoal. I would almost anticipate a little adjustment period while your body adapts to the local cuisine and water supply. Traveler’s diarrhea is common, and anything from street food to gourmet meals (to ice in your soda!) could cause illness. These will detoxify pathogens from your system more quickly, so you’re in less distress and can get back on your feet fast!

  • 11. Female Urination Device

    This may sound odd but ladies, stay with me here! You never know if you’re going to have a clean bathroom to work with (or one stocked with toilet paper). When you’re adventuring off-the-beaten-path, keep this female urination device as a handy tool. It acts as a funnel, allowing you to pee standing up, which is really a privilege that shouldn’t be reserved for men! It has a sanitary case and you won’t regret having it in times of need.

  • 12. Waterproof Phone Pouch

    Whether you’re in Pattaya enjoying epic water sports or sitting poolside at a resort, you’ll need a waterproof phone pouch to protect your phone from the elements. You’ll be indulging in parasailing, diving, snorkeling, and boating, so don’t risk dropping your phone in the water. I always attach a flotation strap to ensure it’s buoyant, and the case will even allow you to film underwater videos!

  • 13. TSA-Approved Luggage Locks

    Sadly, we had really nice sunglasses stolen from our checked luggage. When your bags are out-of-sight for long durations, it will offer sincere peace of mind to attach a luggage lock. We bring a couple of sets for all suitcases, backpacks when exploring crowded areas prone to pickpockets, city lockers, hotel lockers, and more. These are TSA-approved so they’re perfect for flying around the world.

  • 14. Luggage Straps

    These are a small investment with a big pay-off – extending the life of your luggage and saving you lots of time! These secure your bags so they stay shut regardless of how roughly they are handled. This set is our favorite since it can withstand 700+ lbs of force tension and comes with a lifetime happiness guarantee.

    The brightly colored staps mean that no one else’s generic bag looks similar to mine, which is a huge time saver on busy travel days. I can spot my bag the moment it falls from the baggage claim carousel and get on with my day. You could also get creative to use this as a makeshift handle if anything breaks, tether multiple bags together when navigating busy areas, compress your carry-on bag so it fits in the overhead compartment (even if you’ve done some epic Thai shopping!), and more.

  • 15. Cooling Towels

    Thailand is brimming with heat and humidity, particularly in the monsoon season. To make outdoor activities more tolerable, use these cooling towels to beat the heat! These magical cloths are super lightweight and drop to nearly 30-degrees colder than the outside temperature. Simply add water and voila! You’ll have a frosty friend that can be rechilled over and over throughout the day. We never travel anywhere tropical or warm without these.

  • 16. Packing Cubes

    Packing cubes are extremely helpful for staying organized and for preventing your bag from exploding when you open it after it has been thrown around during a long trip. You’ll have a far easier time finding things when you need them and use one for pants, one for shirts, one for excursion essentials, and so on. It even comes with 2 bonus laundry bags, boo-yah! If you want to start small or have less to pack, get the 3-pack set.

What’s the electricity and power supply like in Thailand

Dam in Thailand
A dam in Thailand

Compared to most of Southeast Asia, the electrical grid in Thailand is very well developed. The vast majority of the country has electricity, although some remote villages do not, but you’ll probably only end up there if you go trekking.

However, there’s a reasonable chance you’ll experience a power outage at some point, as they can occur in Bangkok, on the islands, and elsewhere. But unless it’s caused by a storm or planned maintenance, it probably won’t last long.

Something to be aware of is that electric water pumps are common in Thailand – that means that if the power’s out, the water will be off as well. Lastly, plugging in too many devices at once can easily cause the circuit breaker to trip, especially in older buildings.

Do I Need A Voltage Converter for Thailand?

Most of the devices you’ll likely bring to Thailand – like a phone, laptop, or tablet – can operate on a voltage up to 240V, meaning they don’t require a converter.

However, certain American appliances are only rated to 120V, including hairdryers, electric razors, and straightening irons. If you plan to bring any of these, you’ll need a US-to-Thailand voltage converter to use them safely. Trying to plug one of these devices straight into the wall will destroy it, and it could shock you or start a fire. I would avoid bringing these items altogether.

If you plan to go abroad frequently, you could also order a travel version of the devices you want to bring. These will either be rated to 240V or they’ll have a setting that allows you to switch the voltage.

Other FAQs about traveling in Thailand

  • 1. When to Travel to Thailand

    Travel to ThailandHigh season in Thailand runs from December to February, when the weather is slightly cooler and mostly dry. Popular destinations can get extremely crowded then, and prices go up, especially in southern Thailand. In most of the country, November is the ideal month to visit. The peak season crowds (and prices) haven’t yet arrived, the temperatures are nearly as cool as they’ll get, and the rainy season is ending. On the Gulf Coast, though, the best choice is probably March, when the rains and peak season will both be over. Be sure to check current Thailand travel advisories before you go.

    If at all possible, avoid northern Thailand between February and May, when the farmers burn their fields in preparation for the upcoming season, creating hazardous air quality.

  • 2. What is the weather like in Thailand?

    Thailand has a tropical climate, so the weather is mostly hot and humid year-round, and it doesn’t vary much throughout the country. Seasonal differences are also minimal, though the hottest month is generally April, while December to February are the coolest.

    Mae Hong Son in the northwest corner is the coolest part of the country in wintertime, but highs are still in the mid-80s and lows rarely dip below the mid-50s. Rainy season runs from May to October, except on the Gulf Coast, where it typically lasts from September to December. Most destinations see some rain year-round, though, especially in the south.

  • 3. What to do in Bangkok?

    Bangkok is the most-visited city in the world, and with good reason. You could go to a new temple every day for years, but some of the most interesting are Wat Arun, Wat Pho, and Wat Suthat. Don’t miss the Grand Palace, either. There are several museums worth a visit, including the Bangkok National Museum, the Museum of Contemporary Art, and the Bangkok Art and Culture Center. For shopping, browsing, or just people watching, check out both the markets like Chatuchak Weekend Market and Pak Klong Talad (the flower market) and the malls like Siam Paragon and CentralWorld.

  • 4. What to do in Thailand?

    BangkokMany of the top things to do in Thailand are available in most of the country’s popular destinations: visiting temples, browsing markets, taking a cooking class, and getting a massage, for starters. Some of Thailand’s top destinations include the history- and culture-packed Chiang Mai in the north, as well as nearby Chiang Rai, home of the famed White Temple and Blue Temple. For ruins a la Angkor Wat, head to Ayutthaya or Sukhothai.

    If you’re looking for a beach vacation, you can choose from dozens of islands. Do a retreat on Koh Samui, party on Koh Phi Phi, chill on Koh Lipe, or get away from the crowds on Koh Kood. No matter which islands you choose, diving and snorkeling will almost certainly be available. One thing to skip in Thailand?The wildlife attractions like elephant rides and tiger temples, which are, unfortunately, rarely ethical.

  • 5. How to get around in Thailand?

    ferry thailandThailand is very well-connected with many transportation options. To go directly between the north and south, flying is the most feasible, and domestic flights on airlines like Nok Air and AirAsia are usually inexpensive. Thailand also has an extensive rail network, and all but the cheapest classes are extremely comfortable. The second-class overnight train is especially popular for travelers going to and from Bangkok.

    Many companies run buses all around Thailand as well; they’re far less comfortable than the train (and not as safe), but they can be much cheaper and are often even faster. Various ferry companies connect the islands with the mainland, and boats running to the most popular islands are usually quite comfortable.

    Bangkok has a very sophisticated public transportation system, with easy-to-use underground and elevated trains connecting much of the city, as well as dozens of bus routes. Songthaews(public pick-up trucks) also operate in many areas, but you’ll have to ask a local to point you in the right direction. The city has a system of boat taxis as well, which can be very efficient since they avoid the traffic. Other big cities like Chiang Mai also have bus and songthaew systems, and the ride-sharing app Grab is now available in most major towns.
