Travel Power Adapters: Which One Do You Actually Need?
Quick answer
Most modern electronics, including phone, laptop and camera chargers, are dual voltage and only need a plug adapter to physically fit a foreign outlet — not a voltage converter. Check the fine print on your charger for the accepted voltage range, then buy an adapter that matches your destination's specific plug type, or a well-reviewed universal adapter that covers everything on your itinerary.

Adapter versus converter: the distinction that actually matters
These two terms get mixed up constantly, but they solve different problems:
- Plug adapter: changes the physical shape of the plug so it fits a foreign socket. It does nothing to the electricity itself.
- Voltage converter: actually steps voltage up or down, needed only for devices that aren't dual voltage.
Plugging a device into an adapter alone is fine as long as the device itself can handle the local voltage. Using only an adapter on a device that isn't dual voltage can damage the device or, in rare cases, create a safety hazard.
How to check if your device is dual voltage
Look at the small print on the charger brick or the device itself, usually near the input specifications. It will list something like an input range covering both roughly 100-120V and 220-240V. If you see a range like that, the device is dual voltage and only needs a plug adapter abroad. If it lists a single voltage, you'll need a proper converter, not just an adapter.
| Device | Usually dual voltage? |
|---|---|
| Phone and tablet chargers | Yes, almost always |
| Laptop chargers | Yes, almost always |
| Camera battery chargers | Usually, but check the label |
| Hair dryers and straighteners | Often not — check carefully |
| Electric shavers | Varies by model |
Plug types: it's about shape, not electricity
Plug types are labeled by letter (for example Type A, C, G, I) and the type used varies by country, and occasionally by region within a country. There's no shortcut here beyond checking your specific destination before you pack, since assuming a neighboring country uses the same plug is a common mistake.
Choosing between a single adapter and a universal one
If you're visiting one country, a simple, inexpensive adapter matched to that plug type is all you need. If your trip spans multiple countries with different plug standards, a universal adapter is more convenient, but check the specific product's listed coverage against every country on your itinerary rather than assuming "universal" means every plug type without exception.
Packing and using adapters safely
- Pack your adapter in your carry-on, not checked luggage, in case you need it during a layover.
- Avoid stacking multiple adapters or cheap multi-plug extensions on a single outlet, which can overload it.
- If you're traveling with a device that needs a genuine voltage converter, buy one rated for the device's wattage, not just its voltage.
- Hotel rooms sometimes have a mix of local and international-style sockets built in near the desk or bedside — check before assuming you need an adapter for every outlet in the room.
What about USB and USB-C charging?
If you're charging primarily through a USB wall adapter or a USB-C laptop charger, the same dual-voltage logic applies: check the input rating printed on the charger. Many travelers now carry one multi-port USB charging block plus a single plug adapter, rather than several individual device chargers, which also saves outlet space in hotel rooms with limited sockets.
Once you've packed, don't forget the flight itself
A good adapter is a small detail, but it's the kind of thing that's easy to forget while focusing on bigger trip logistics like flights and accommodation. Compare fares early so you have time to sort out the smaller packing details before departure day. Browse popular routes on ScanFlyGo →
Frequently asked questions
What is the difference between a travel adapter and a voltage converter?
An adapter only changes the plug shape; a voltage converter changes the actual voltage, which is only needed for devices that aren't dual voltage.
Do I need a voltage converter for my phone charger?
Almost never, since phone and laptop chargers are nearly all dual voltage. Check the input voltage range printed on the charger to confirm.
How do I know which plug type a country uses?
Plug types are labeled by letter and vary by country and sometimes by region, so look up your specific destination rather than assuming.
Can I use one universal adapter for every country?
A good universal adapter covers most plug types, but confirm it explicitly lists every plug type on your itinerary before relying on it alone.
The bottom line
Most trips only need a plug adapter, not a voltage converter — the label on your charger will tell you which one you actually need. Sort the small stuff early and put your attention where it counts: compare flights on ScanFlyGo for your next trip.
