Welcome to the Too Many Adapters resource page, a compilation of tips, advice, and resources gained from many years of working with and writing about travel technology. 

This page is, and will always be, a work in progress. We’ll be updating it all the time, but if there’s anything missing that you’d like to find out more about, just get in touch.

Before You Go

Consider Your Destination

Where you’re planning to go should help determine the gear you’ll travel with. Start with power. If you’re going somewhere that has different wall sockets to those at home, you’ll need a travel adapter. If the voltage is different, you may need a transformer as well.

If heavy rain is a possibility, waterproof luggage and dry sacks will prevent your gadgets from drowning. Cases and zipped bags help keep dust at bay — buy padded versions if you can, to soak up some of the inevitable bumps and knocks.

If crime is an issue, avoid brand name or expensive-looking gear, and keep everything out of sight in a plain backpack or similar as much as possible.


Traveling without insurance is risky. If you’re seriously injured, emergency evacuation and treatment can easily cost hundreds of thousands of dollars. When considering a policy, also take note of coverage for lost, stolen, or damaged electronics.

Many policies limit the amount they’ll pay on individual items to a few hundred dollars or less, so make sure you’re actually as covered as you think you are.

It’s sometimes possible to specify high-cost items (at extra cost), or pick up dedicated electronics insurance if you need it. Read the fine print!

If you’re planning to use your phone overseas, it’s usually much cheaper to buy a SIM card from a local company than roam with your plan from back home. For this to work, your phone needs to be unlocked. If you got it free or discounted with a contract from your cell company, it may not be.

You’ll also need to consider charging requirements and network support. It’s a good idea to make sure your smartphone is ready for your trip before you leave, as it’s usually harder to sort things out while you’re away.

Choosing the Right Gear

When choosing electronics to travel with, you’ll often end up juggling several competing factors. It’s important to keep the weight down, for instance, but the gear still needs to be durable to handle the knocks of the road.

Avoiding high-end, brand-name gadgets helps put off thieves and save money for the actual travel, but warranties and reliability matter, especially when you’re far from home.

You’ll always end up with a compromise of some sort, but it’s important to know what you’re actually compromising on.


Lugging around heavy bags and suitcases is one of the least enjoyable parts of the travel experience, so try to reduce weight as much as possible. Check out the total weight of anything you buy, including adapters and chargers. Cheap laptops are particularly bad in this regard: not only do they usually weigh a lot, but their chargers are often huge and heavy.

Remember that all of your electronics should travel in your day pack/carry-on luggage, and airline weight limits can be particularly severe.

Your gear will get a hard time when you travel, with dust, water, humidity, heat, cold, knocks, and drops all taking a toll. Avoid electronics that break easily. Check the reviews for anything you’re planning on buying, and if there are more than a few reports of early failure, look for something else.

Consider the rugged versions of things like phones and hard drives, and add your own protection in the form of padded cases and dry sacks.

Brand Names

In general, brand-name gear is a good thing. Warranties are more likely to be international in nature and honored at all. Problem-solving is easier — there are entire websites dedicated to iPhone problems, for example — and in some cases you’ll get a higher-quality product by buying from a known brand.

Don’t discount generic or less well-known gear entirely, however. Generic laptops use generic parts, something you’ll be very happy about when your laptop charger dies in a small town in the Philippines and the nearest Apple or Sony store is a plane ride away.

Prices also tend to be lower, which is always a good thing, and a plain black phone or laptop is less of a target for thieves than something with logos emblazoned all over it. 

We take these factors and more into account when choosing our recommendations for the best items for travelers across a range of categories.

Staying Connected

Staying connected to the online world has become increasingly important to travelers in recent years, and while it’s getting easier all the time, it’s still nowhere near as straightforward as back home.


Check online accommodation reviews to find whether a place has free Wi-Fi for guests, and whether it’s reliable. To speed up your internet connection, consider investing in a good Wi-Fi range extender to boost signal strength and, with a bit of software magic, even use multiple Wi-Fi networks at once.

If you’re using a network that only lets you connect a single device, don’t worry. There are ways to share your connection for free or cheap once you’ve got it. It’s also worth finding out whether the city you’re staying in has free Wi-Fi in downtown areas (an increasing number do), or whether public libraries, phone companies, or cafe chains offer something similar.

Calls, Texts, and Cell Data

As people become used to having mobile data on their smartphones and tablets at home, they increasingly expect the same thing when they travel. While a domestic trip rarely poses a problem, high international roaming charges and locked devices make things more difficult overseas. There are several options available, some cheaper and easier than others.

Check with your carrier to see if they offer free or discounted international roaming options. A small but growing number of cell companies include some form of global roaming in their existing plans, or make it available at a reasonable cost.

If they don’t, find out whether your phone has an unlocked SIM card slot. The chances of this vary by country and carrier — in most (but not all) cases, a discounted phone purchased with a fixed contract will be locked to the carrier you bought it from, and other SIM cards won’t work.

You can ask your carrier to unlock the phone if necessary (some will, some won’t), or use a warranty-voiding third-party service to do so. To avoid such problems entirely, buy an unlocked smartphone to start with.

Once you have an unlocked phone, buy a local prepaid SIM card at your destination, and use it for the duration of your stay. Prices for the card and a reasonable monthly call, text, and data package generally range from $10-50 depending on where you are.

If you’re only spending a few days in each country, it may be worth considering an international SIM or rented Mi-Fi device (see below) instead.

Mi-Fi (Mobile Hotspots)

For those who can’t use local SIM cards, or don’t want to deal with the hassle of buying them, Mi-Fi mobile hotspots are another option. These pocket-sized gadgets typically let you wirelessly connect five or more devices to them, and share cellular data among them all. Many companies offer a rental service for Mi-Fi hotspots, spanning one or more countries.

We’ve reviewed various rental Mi-Fi devices in the past, and typically found them a useful, albeit expensive, choice. Depending on the company, your trip duration, budget, and data requirements, they may or may not be an affordable option. Always check the fine print carefully.

If you’d prefer to own a Mi-Fi device, these can be purchased with their own data plan, unlocked for use with local SIM cards, or in some cases, both. If you travel regularly and need to get several devices online, these options are worth considering.

Security and Backup

Security isn’t a sexy topic, but it’s an important one when you travel. You’re often less secure both physically and electronically when you travel, and the consequences of an attack can be expensive, dangerous, and hard to recover from.

Public Wi-Fi

You’re more likely to use public Wi-Fi when you travel, especially if you don’t have access to cellular data. Airports and train stations, cafes and bars, hotels, and guesthouses all often provide access to their customers. This is very convenient for travelers, but comes at a cost: security.

It’s frighteningly easy to find programs that will automatically scan a wireless network and grab usernames, passwords, and other useful details as they pass by.

With hundreds or thousands of people having access to most public networks, it only takes one malicious individual to cause real problems. There are several ways to reduce the risk of using public networks, but the simplest and most comprehensive is to use a VPN to automatically encrypt everything that you send and receive.

Resources: VPN providers worth considering include ProtonVPN, ExpressVPN, and TunnelBear

Public Computers

If public Wi-Fi is a big security risk, public computers are an even bigger one. It’s easy for an attacker to install what’s known as key logging software onto these computers, which capture sensitive information as it’s typed in and then send it off for later use.

Combine that with the usual mixture of viruses, malware, and other dubious software often found on such computers, and they’re just a disaster waiting to happen.

We recommend against using public computers (including those in internet cafes, hostels, and hotel business centers) unless you absolutely have no other choice. While some machines have good security measures in place, many don’t, and it’s hard for most people to tell the difference.

If you really must use them, avoid logging on to internet banking or similar services, and change the passwords on the other accounts you use (from a secure computer!) as soon as possible.

Two-Factor Authentication

Before you travel, make sure to enable two-factor authentication (2FA) for as many online services as possible. This combines something you know (like a password) and something you have (an SMS message, fingerprint scanner, or special app) to create single-use passwords.

Even if your account information is stolen, nobody else can use it to log in as long as you have 2FA set up. Since SMS-based systems can be a problem for travelers, check out options like the Authy app instead.

Physical Security

When you’re in unfamiliar surroundings and potentially carrying more valuables than usual, theft is a real risk. There’s plenty you can do to reduce the chances of being a victim, however.

Start by avoiding the use of electronics on the street or other public places. Keep your phone and other gadgets in a bag or pocket until you’re somewhere less visible, and don’t put them on the table in restaurants and cafes.

Opt for plain, somewhat-worn day packs to carry your gear around, rather than flashy, brand-name luggage, and keep the zips locked where possible. There are plenty of other travel security options, too, including alarms and trackers for when the worst happens.

As always, if you do find yourself face to face with someone set on stealing your equipment or money despite your best efforts, give it to them. Possessions are replaceable, a life is not.


We talk a lot about backup on this site, and with good reason. It’s very easy to set up a system that works for you, yet backups are often ignored until it’s too late and those irreplaceable travel memories have been lost.

Our basic rule with data of any sort is “if it’s only stored in one place, it’s something you don’t mind losing” … and sadly, we know far too many people who have done exactly that after a travel mishap.

Start by remembering to copy photos off camera SD cards every day or two. If you’re traveling with a laptop, buy an external hard drive and use Time Machine (macOS) or File History (Windows) to automatically back up everything that matters to that drive.

If you’ve don’t travel with a laptop, you can use a combination of an SD card reader and a wireless hard drive to do the same thing from a tablet or phone.

It’s important to keep a backup ‘in the cloud’ as well — there’s not much point having a copy of everything on an external drive if it gets stolen, lost or damaged at the same time as your main device. We reviewed several tools for making automatic cloud backups, and Backblaze came out on top for most people.

Don’t forget to upload photos taken on phones and tablets to a cloud service as well. Services like Google Photos and Apple iCloud can be set to automatically do so whenever they’re connected to Wi-Fi.
