Traveling Soon? Here’s How to Keep Your Devices Safe
Yes, you can charge your devices safely abroad. The key is knowing how voltage, plug types, and surge protection differ from country to country. Plugging into the wrong outlet without the right adapter can instantly fry your phone or laptop.
Voltage and Plug Differences by Region
Countries use different voltages and plug shapes. Most of North and South America use 110–120 volts, while Europe, Asia, and Africa use 220–240 volts. This means your devices might not always be compatible straight out of the box.
Here’s a quick overview:
| North America | 110–120V | Type A, B |
| Europe | 220–240V | Type C, E, F |
| UK & Ireland | 230V | Type G |
| Australia & New Zealand | 230V | Type I |
| Japan | 100V | Type A, B (same as US shape, lower voltage) |
If your charger label says “Input: 100–240V,” it’s dual-voltage, safe to use almost anywhere with just a plug adapter. If not, you’ll need a voltage converter to step the power up or down safely.
Choosing the Right Adapter and Converter
Adapters only change the plug shape, they don’t change voltage. That’s where travelers often make mistakes. Converters, however, transform the electrical current so your device receives the correct voltage.
For best results, choose a universal travel adapter with built-in surge protection. These compact tools work across multiple regions and protect against sudden voltage spikes, common in older hotels or rural areas.
Travel Tip: While you’re checking voltage or plug types, Eskimo eSIM lets you skip SIM cards and access local data plans instantly, no kiosks, no swaps, just seamless travel tech.
Avoiding Power Surges and Damage
Power surges are unpredictable and can happen even in well-developed regions. A small surge can permanently damage your charger or laptop. Here’s how to minimize the risk:
- Use a certified travel surge protector to absorb spikes.
- Avoid unbranded or uncertified adapters.
- Don’t plug high-wattage items (like hair dryers) into low-capacity converters.
- Charge devices when you’re present, not overnight.
- Unplug immediately if a converter overheats or emits odor.
If you’re unsure, buy a converter with automatic voltage detection, they adjust safely between 110V and 240V.
Practical Tips for Charging Devices Abroad
- Label your chargers to prevent mix-ups when sharing outlets.
- Carry a multi-port USB charger to reduce adapter clutter.
- Bring a backup adapter, as not all airports stock the right plug type.
- Check voltage charts before plugging in, a quick look prevents expensive mistakes.
A few minutes of preparation saves both your electronics and your peace of mind.

Eskimo’s fixed data plans come with 2-year validity and unlimited data rollover, no SIM swaps, no delays, just modern, reliable travel essentials that keep you ready from your first charge to your last upload. So you only pay for what you use.
FAQs
Do I need a voltage converter in Europe?
Only if your device isn’t dual-voltage. Most modern chargers already support 100–240V, so an adapter is usually enough.
Can power surges damage phones or laptops?
Yes. Even minor surges can shorten battery life or destroy charging circuits. Use a surge protector whenever possible.
Is a universal adapter really universal?
Not entirely. Check that it supports the plug types and amperage for your destination region.
Can I use my US hair dryer in the UK?
Only if it’s dual-voltage or used with a proper converter rated for 220–240V.
