I'm looking for a schematic for a power converter to convert 110V to 220V for a 1.5W Chinese shaver. I know I could buy an adapter or converter online or travel store but what's the fun in that. I like doing little projects on my own. Things I've come across though (schematics) are large heavy transformers for high powered loads. I'm needing something small and light if possible. The device power input is 220V 50Hz 1.5W. Any help would be greatly appreciated.
