Will this LED rope light kit work in Tokyo, Japan?

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?

Too many volts?

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]

Bringing our US electrical devices to the UK / also NTSC-PAL question

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]

Is my new (aftermarket) power adapter safe for my laptop?

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]

Can I use a 220v device in the UK?

Can I use a lightbox purchased online from the US, which includes an international voltage adaptor for 220v, in the UK? I think the UK mains voltage is 240v and have no idea whether I have to be bang on 240v or if 220v is good enough. [more inside]

Is it safe to keep a step-down converter turned on at all times?

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?
