It's nice that USB may become a standard for charging things.
I have two of these, that cost under $5 each:

I use them to charge my iPod touch and my bicycle GPS.
It might be significant to note that the standard iPod or iPhone chargers only put out five watts. The iPad wants more juice, so its charger puts out ten watts. These outlet chargers also put out ten watts, so they are iPad compatible, which is nice (and probably a developing trend).
