USB wall wart...
A number of products, such as the Applie iPad, come with a device that plugs into a standard 120-Vac outlet and outputs 5-Vdc through a USB connector. During my several visits to Fry's here locally during December, there was a bin of these units on sale for about $5 each. A need for an extra unit arose this past weekend and after seeing a price of $13 for one at the local supermarket, I decided to return to Fry's.
I managed to do that today, and found that the bin was gone and the least expensive charger available was a NuGiant charger for about $10. What is unusual about the unit is that it doesn't actually plug into an outlet so much as slip over a three-prong plug that, in turn, plugs into an outlet. It's actually a pretty clever design that provides functionality without impacting the availability of outlet receptacles.
Whether it will stand up to a lot of day-to-day handling is another issue, but one I don't expect to have to worry about all that much once I get it installed where it's needed.
Cheers...
