Voltage Converter Guide

What is the proper voltage for your next travel destination?

The electric outlets overseas and in many other countries provide a higher voltage than standard N. American outlets.
View the map below to find the proper voltage for your next travel destination.

Dual or Single Voltage?

Your device will fall in one of three categories: dual voltage, 110-120V only or 220-240V only. If your appliances are not dual voltage, you’ll need a voltage converter or transformer to use them in a country with different voltage outlets. Don’t know if your device is single or dual voltage? There’s an easy way to find out!

  • If your device is dual voltage, you do not need a converter or a transformer. Just an adapter.
  • The most common dual voltage electronics include cell phones, iPhones, tablets, iPads, laptops chargers, camera battery chargers, CPAP machine adapters, and even PCs.
  • If your device is 120V (includes 110V or 125V) only, you will need a converter or transformer that will “step down” the voltage overseas to safely power your North American 110-120V device.
  • If your device is 220V (includes 230V or 240V) only, you will need a converter or transformer that will “step up” the voltage to power them in the 110-120V countries.

Figuring Out Your Device’s Required Wattage

After you determine your device voltage, the next step is figuring out the required wattage. Find your device’s power by looking at the label for a number followed by a W, mA or A. These stand for Watts, milliAmps, and Amps. If you see the watts, you can move to the next step. If you have mA or A, you’ll have to do a bit of math. Don’t worry; it’s easy.

Voltage Convertion Key
Watts = Voltage x Amps Example: 120V x 0.8A = 96W
Amps = milliAmps x / 1000 Example: 5mA x / 1000 = 0.005A

The Final Step: Choose the Right Converter/Transformer

You’ll want to look for a converter or transformer that provides just a bit more wattage than you need. Devices tend to surge up when they’re turned on, so that little bit of extra power required needs to come from somewhere.

Commonly Used Transformers & Converters

The best option for 96-watt devices is our Ceptics PU-151 Transformer. It’s designed to work with electronics with up to 150W of power. As a step-down transformer, it will convert the 220V found in abroad outlets to 110V for use with North American electronics rated less than 150W.

The Ceptics PU-200 200W Travel Voltage Converter works with products rated up to 200W. Both of these also features 4 USB ports to power your USB devices such as an iPhone, iPad, and other tablets or cell phones.

Safety First

Please note the higher the power requirement (watt), the larger and heavier transformer you’ll need. A typical 2000W transformer can weigh up to 15 pounds, making it less than ideal for travel. However, a 2000W voltage converter is much smaller and compact. 2000W converters are designed for purely resistive electricals without circuit boards, such as standard hair dryers.

Our voltage converter vs transformer guide goes over converter and transformer differences is greater detail. We recommend staying away from such high-powered small voltage converters all together. Choose a safer and more convenient option, by traveling with a dual voltage hair dryer instead.

Let's Recap

  • Determine your device’s voltage.
  • Figure out required wattage using the equations above.
  • Choose the right converter or transformer. We suggest Ceptics PU-151 for electronics up to 150W of power or Ceptics PU-200 for up to 200W of power.
