I'm trying to set up several micro USB charging stations in my house and car, and I'm realizing that I retain very little from 9th-grade Intro To Electronics. Set me straight on how current works? [more inside]
Recently I found a good deal on a direct drive DJ turntable which was manufactured for the japanese market. I know japanese consumer electronics run on 100V while US runs on 120V. I have heard conflicting things on whether this would be an issue. It seems like the turntable would likely run but I have heard some reports that this difference in voltage might eventually damage it. Is a power adaptor a permanent solution to this problem? Is a power adaptor even necessary?
This is the appliance in question. I'm aware that Tokyo's electrical system is 100 volts at 50 Hz, but I'm not sure how that applies to this rope light kit, which is rated for (according to the instructions) 120V, 60Hz, and 100 mA. Does the low current/wattage (12 watts) mean it will work anyway, due to some transformer inside, or is it just not going to be compatible?
I'm moving into a new (to me) NYC apartment, and I need to buy two window-unit air conditioners. The super said that the power there is 110 volts, but the ACs I want are 115 volts. Is that a problem? [more inside]
It's generally advised to leave as much behind as possible when moving abroad, but my wife's employer is paying to have a decent amount of our household stuff transported from the US to the UK. And why would we want to waste money buying duplicate items if it isn't necessary and we probably won't be staying more than a couple years? So I'm trying to figure out which of our electronics and appliances might be made to work overseas. I am aware of the voltage difference and the line/mains frequency difference between the US and the UK and I'm considering buying one or two good-quality step-down voltage converters for things that aren't universal voltage compatible. But I have some questions that my Google research has not cleared up. [more inside]

I just returned (to the US) from a trip to Korea, where I was given a really nice gift: a fancy Cuckoo Induction Heating Korean rice cooker just like this one.

I'm setting up my "off the grid" solar lighting system in my home, and I'd like to connect the battery to some LED lights. It's a 12 volt DC battery - Do my lights have to be 12 volt also? If they're LED bulbs, they'll have a transformer inside; will that allow me to use them, or do I have to have a voltage converter or something? I've got some edison-style LED bulbs around the house for 85-265 volts. Thanks in advance for any help. pictures and web links that can explain things simply are helpful.

Can I damage my laptop by using a power adapter that has a slightly higher wattage than the original adapter? The original adapter was 65W, and the aftermarket one is 70W. The voltage is switchable. My original adapter had a voltage of 18.5V, this one says that if I need 18.5V, I should choose 18V. Any chance of damaging the computer by using this one? [more inside]

I have a Electric shaver, Electric kettle and a Sandwich maker that uses 230V. They have round type pins in the plug. I would like to use them in USA. So I need to find a 110V to 230V voltage converter that also supports round pin plugs. I found this worldwide adapter plug in Amazon, and it seems like the idel thing I'm looking for except for the fact that it doesn't convert voltages. So if I can find something similar to this which converts from 110V to 230 v and vise versa it would be great. If it's not possible at least a one that converts from 110v to 230v. Please recommand me any converter that you are satsfied with and show me a place to buy. Thanks in advance.
I just picked up a 1000W step-down converter (220V-110V) to power a receiver after a 750W exploded in a blaze of glory when I turned it on one morning. I'd very much like to avoid this kind of thing again. So my question is, is it relatively safe to keep step-down converters turned on at all times? If so, will it constantly be using 1000W of power even when the receiver is turned off? I've heard differing opinions but found no definitive answer on the interwebs. Related, is it true that you should always have something plugged into the converter when it is turned on?
