[sdiy] In my quest for battery powered equipment...

[The Peasant]

The quality of these can vary a lot, so you should be careful. The outputs are 
rarely pure sine waves, and can be full of harmonics, so you may need lots of 
DC filtering. I would recommend a higher quality type for better stability and 
less harmonics.

Take care,
Doug
