Obvioulsy check the device, I will return to that in a moment. However the reason I said I disagreed was because that's not what I read your previous post as actually saying. To me, your previous post is actually saying that "for high value items, get a converter (regardless)".

I know you say in the next sentence to check the spec, but if this is your meaning I don't understand the 'high value items' bit in the sentence before. Even if the item is easily replaced and unimportant, do NOT go plugging it in without checking specs. Hence, the only logical meaning I could take from your post was an advocation of using voltage converters on high value items regardless of whether they were necessary based upon spec. And it was this I was disagreeing with.

I also would not recommend googling specs but rather checking the spec on the device itself. Some items are manufactured under largely the same codes (sometimes exactly the same) with voltage specific power supplies in different markets. Or in some cases, with both voltage specific and also multi-voltage power supplies on different versions under the same code produced at different times, or to keep flexibility of market.
So, if just searching for an XYZ-123 it may not necessarily be the same XYZ-123 that you have that they are talking about. However the label on the device should say with regard to your specific one.
Indeed, even in the same country, I've seen same devices sold with both 110V and also 110-230V supplies on different instances. (And the other way too).
