Ok, I live in China.
(Like my name doesn't give that one away)
And for a long while, I was limited as to what I could purchase because I always had to look at the company's homepage and try to search for the voltage, and wattage and all that other fun stuff when electronics are shipped from one country to another that are not battery operated but by power cord.
I never could have a Fairy Wand, or the Eroscillator, or even the Hitachi. And then trying to search for information on Lelo, Fun Factory, Je Joue and all the other wonderful rechargeable toys... I had to spend hours and hours searching to see if I could plug them into my wall, or if I had to just forget about buying the item.
A friend of mine sent a ticket to Customer Service asking if on the product page if it were possible to have the electrical information mentioned as there are a lot of us who order from EdenFantasys from around the globe.
The reply she received was, "they all can work in America."
Which unfortunately, didn't really help much until we read that quite a few of the recharging toys are universally power friendly.
However toys like the Eroscillator, the Hitachi cannot be used outside of North America without a transformer.
Not an adapter.
One of the issues of using an adapter is that the items/product/electric al thingie, will work but it adds so much strain to the motor. And as a result, making it wear out faster. So instead of a hair dryer lasting you for five years, or a life long sex toy, a hair dryer might last you less than a year of daily use, and a sex toy will last you a few years of frequent use, before the motor burns out.
Please note if you are travelling for a couple of weeks, usually an adaptor will be suitable for most types of electronics. Please pay special attention to your lap top/camera/phone information as many companies have gone the way of international plug ins.
