Outlets or plugs: which to choose when traveling so you don't run out of battery

You have your tickets, passport, first-day outfit, and even your flight playlist ready. But there's one question many people leave until the end: Will I be able to charge my devices as soon as I arrive? 🔋 Because yes, you can survive without unpacking your suitcase on the first day, but arriving with your phone at 2% and discovering that the hotel's outlet looks nothing like yours... that really spoils the start of any trip.

The good news is that understanding this topic isn't as complicated as it seems. You just need to be clear on three things: the plug type, the voltage, and the frequency. With that sorted, you avoid buying extra accessories, damaging a device by plugging it in incorrectly, or ending up frantically paying for an improvised adapter at your destination. ✈️

🔌 First things first: an adapter is not the same as a converter

Here's the most common confusion. An adapter only changes the shape of the plug so your charger can fit into the wall socket in the country you're visiting. It does not change the voltage of the power. In contrast, a voltage converter does transform the current so that a device designed for 110V can work in a place where the grid operates at 220V, or vice versa. A universal adapter provides physical compatibility, but does not replace a voltage converter.

So, what do most travelers need? Actually, much less than they think. Most modern phone, computer, tablet, camera, or watch chargers say something like "Input: 100-240V, 50/60Hz" on the label. When you see that, you can breathe a sigh of relief: it means that charger is multi-voltage and, in most cases, you only need a plug adapter.

What should you be careful with? Devices that generate heat or use a motor: hairdryers, hair straighteners, old shavers, small fans, or some electric toothbrushes. In these cases, just "fitting in" isn't enough. If the device doesn't support the local voltage, you could burn it out in seconds. And if it also operates at a different frequency, it might perform strangely or work under strain.

🌍 If you're departing from Colombia, this quick map will save you

From Colombia, here's what you need to know

In Colombia, we use Type A and B plugs, with a voltage of 110V-120V and a frequency of 60Hz.

This means that if you travel to countries with the same system, you normally don't need an adapter to charge your phone, computer, or tablet.

1. No adapter needed 🟢

Countries where you can plug in as you do in Colombia

If you travel to destinations like the United States, Canada, Mexico, or Japan, in many cases you don't need an adapter, because they use plugs that are the same as or compatible with those in Colombia.

What does this mean?
You can plug in most of your chargers without a problem: phone, computer, tablet, camera, or smartwatch.

Short note:
Even if the plug is compatible, it's always worth checking the voltage if you're plugging in more delicate or heat-generating devices.

Suggested countries on the map:
Colombia, United States, Canada, Mexico, Japan

Small technical reference:
Types A and B

2. Adapter needed 🟡

Countries where the plug changes

In much of Europe, the United Kingdom, Australia, and several Asian countries, you do need an adapter, because the plug has a different shape.

What does this mean?
Your phone and computer chargers will normally work fine, but they won't directly fit into the wall socket.

This applies, for example, to:
Spain, France, Germany, Italy, United Kingdom, Ireland, Australia, New Zealand, China, South Korea, Hong Kong

Small technical reference:
Types C, E, F, G, I, and others depending on the country

3. Watch out for voltage 🔴

Here you must check carefully before plugging in

Many countries outside of America use voltages of 220V to 240V, while in Colombia we work with 110V-120V.

What does this mean?
Most modern chargers do work because they accept different voltages. But hairdryers, straighteners, curling irons, and other heat-generating devices can easily get damaged if they are not designed for that voltage.

Always check your device's label:

• If it says 100-240V, you're usually good.
• If it doesn't say that, it's better not to plug it in.

Destinations where this point matters a lot:
Europe, United Kingdom, Australia, China, South Korea, Southeast Asia, Hong Kong

Highlighted phrase:
The greatest risk is usually not with the phone charger, but with the hairdryer and straightener.

4. Special cases 🟣

Destinations where it's worth checking twice

There are countries that don't easily fit into a single rule, and it's worth checking them before traveling.

Brazil

Uses different plugs and the voltage also changes depending on the city or region. In some places you'll find 127V and in others 220V.

Japan

Although it uses plugs compatible with Colombia, it operates at 100V, so it's worth checking sensitive or heat-generating devices.

India / South Africa

Have less common plugs, so a basic universal adapter may not always be enough.

If your destination falls into this category, don't improvise: check before plugging in.

Cell phones, computers, tablets, and cameras usually work without issues if their charger says 100-240V.

Hairdryers, straighteners, curling irons, and other heat-generating devices can be easily damaged in countries with different voltages than Colombia.

If in doubt, it's better not to plug them in.

🛒 So, which plug or adapter should you buy?

If you're taking a one-off trip to a single country, you can just buy the specific adapter. But if you're someone who plans routes with friends, has layovers, or seizes every opportunity to cross borders, a universal adapter is really worth it. The best models today usually cover A, C, G, and I, come with USB or USB-C ports, and add protections like a fuse or safety shutters. Among the most recommended brands by specialized media are options from Epicka, Ceptics, BESTEK, Anker, and TESSAN, though note: not all cover India or South Africa.

Here's an important piece of advice: don't buy the first one you see just because it "works for everything." In the United Kingdom, for example, authorities have issued safety alerts about unsafe adapters due to risk of electric shock. It's also recommended to look for recognized brands and visible certifications on chargers and electrical accessories. In short: better to buy well once than risk your phone, computer, or, worse, your safety.

And where to buy them in Colombia?

Before you travel, in Colombia, you do have easy options. At Conecty, you can find universal adapters on our website or through our WhatsApp line, so you can resolve that detail before taking off. However, it's important to remember that an adapter does not convert voltage; it only allows you to plug your devices into wall sockets with a different shape.

⚠️ Be very careful with charging at public USB ports

It might seem practical to plug your cable directly into a public USB port at the airport, hotel lobby, or train station, but it's not always the safest. The CISA, the cybersecurity agency of the U.S. government, recommends not charging your device in a public USB port without a data blocker, because these ports can be manipulated to expose device information. The safest option remains using your own charger connected to a traditional outlet, or a reliable power bank.

📱 It's not all about the plug: you also need connection as soon as you land

Being able to charge your devices is key, yes. But something equally important is having internet as soon as you arrive. Because as soon as you land, you need to check your accommodation reservation, request transportation, notify that you arrived safely, or locate yourself on the map without relying on airport Wi-Fi.

That's why, in addition to checking what adapter you need for your destination, it's worth leaving Colombia with your connectivity sorted. With Conecty's international eSIM, you can arrive connected from the very first moment, without looking for physical chips, without queues, and without starting your trip rushing after a Wi-Fi network.

Because ultimately, being prepared for travel isn't just about knowing what plug to use, but ensuring your phone truly responds when you need it most. ✨
