My old laptop blew the motherboard after 3 years of great use (Acer Aspire 5670). I just bought a new laptop (Acer Extensa 5630Z). Can I use the power charger/AC Adapter from my old on my new without doing damage? The new one is rated 19V 3.43A. The old one is 19V 4.4A. (plugs are the same). Long live the hive mind!

Like most mefites, I have far too many gadgets, and the wall warts to match. I suspect most of them could be replaced with a single USB charger - is this something that already exists? [more inside]

Electricity: I'm wiring up a new dishwasher with the power cord from the old dishwasher. Just to make things interesting, the power cord has absolutely no indication of which side is positive and which side is negative. Is this because it's AC and it doesn't matter? I'm in the US on 110.

TransformerFilter: I've just relocated to the US and have a rechargeable drill that uses a 17V DC transformer. I need to replace the transformer, since the one I have runs on 240V power (and has the UK prongs). The problem here is that I can't find a suitable replacement at the likely suspect places: hardware stores, Radio Shack...

I know that the voltage must match precisely and that the amperage must be at least as high as the noted amperage, and that the polarity must also match. So where can I go to find a good transformer? I'm in NYC, but I prefer to shop online.
