USB power adapter requirements

You’re vacationing in Italy, sitting on your hotel room’s motel floor, cell phone charger in hand, staring at the electrical outlet because you can’t remember the damn voltage requirements for that country. After a few minutes you decide, ‘the hell with it’ and plug it in.

That seemed like such a good idea at the time right?

But low and behold your charger, blow dryer or other electrical device blows out and now you’re left with a no mobile phone and a ‘low-flow’ Seinfeld shower head.

 

Complete Electrical Requirements by Country List

In the table below we’ll summarize the basic electrical requirements for most countries of the world. The voltages listed here are the most common reported to be in use at most residential or commercial sites in the country or area mentioned. So some electrical power systems in smaller cities might be prone to slight variations in voltage due to demand or other factors – like the fact that they have electricity at all.

Many 220 V countries have converted or are in the process of converting to the EU standard of 230 V. Generally though, this difference isn’t a big deal, as most appliances are designed to work with current a certain figure above or below the rated voltage.

The electric power frequency is shown in the number of hertz (Hz). Even if voltages are similar, a 60-Hz clock or tape recorder may not work on 50 Hz current – So pay attention to the frequency! All systems we’ve mentioned below use alternating current (AC). The plug types we’ve included display all types known to be in use in that country for general purposes. Not all areas of a country may use all types of plugs listed for that country, since there are sometimes regional differences based on the power system in a certain area. We’ve included a description for each electrical plug below.

Finally, only information that is likely to be relevant for travelers is included here. Take a look and leave a comment if you have any questions!
