I recently bought a vintage flip-digit radio alarm clock from ebay, because I plan to refurbish it and basically use it for the rest of my life. However I only realized that the device must be connected to mains when I had already bought the thing. I was assuming it would just work on 12V like most small electronic devices, but I guess because it's from the 70's I can't live in such luxury yet.
The alarm clock is rated for US mains, so 120V 60Hz, and requires only 8W of power. The ratings where I live (Europe) is 230V 50Hz, so I have a couple of questions that I would like to have answered. I searched the web but nothing could tell me the answer to my clock-specific questions.
- Can I just plug the thing in my 230V supply? Do you reckon it has an internal converter or is it really 120V only?
- I have found several cheap converters from US to EU power rated max. 100W, but they do not specify the frequency of the AC. Do you think these converters, which cost around $30, convert the frequency as well?
- Is it a problem if the frequencies don't match? Will my clock run 16.67% slower on the 50Hz AC?
- The clock is only 8W, so might the $30 adapter too imprecise (by lack of better words) when it outputs less than a tenth of its maximum power output?
- What do you recommend?
Thank you for your time and I'm looking forward to reading your responses.
