We've lost the original transformer for our Christmas lights, will there be any problems with running on a differently rated transformer? Lights are LEDs and both lights and transformer are rated at 1 amp.

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. (An earlier, relavent post:

I've lost the charging dock and AC adapter for the Logitech MX Revolution mouse. There's no way to charge this mouse without the dock.

Moving a desktop computer internationally - we're moving from Korea (220 V) to Canada (110V). Is it as simple as removing the power "section" of the desktop and replacing it with 110 V at a computer repair place in Canada? Are internal components individually responsive to a particular voltage?

Just returned from fabulous 2 week holiday in New York. I Brought back Epson Artisan 800 All-in-One Printer from Staples costing $230. Unfortunately, I cannot use it in U.K., unless I plug voltage converter/transformer products. Has anyone else bought this set over there with more success?
Any advice \ information appreciated.
Please specify me What exact voltage converter product to buy & where to buy it from USA online store. Thanks. [more inside]

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 recently lost the power adapter for my olde tyme Creative Nomad Zen NX. I'd like to just drive down to RadioShack and get a replacement, but I'm not sure what I need. The Nomad wants 5V, but it looks like RadioShack's adapters skip from 4.5V to 6V. Will I kill my player if I use one of those options?

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?

I have an older travel trailer that I am turning into a guest house. The trailer runs on 110/120 volts and the main powercord has an oversized end plug with angled blades and cylindrical grounding plug. Kind of like the powerplug on an oven. How do I go about converting this to work with the existing 220/240 breaker? Is it complicated / unwise to do this myself? My electrical experience is limited to installing new light fixtures and electrical outlets.
