Fifty {Two} Shades of Grey - Week 22

As promised... more battery charger...
I just need to add at this point in time, that this was surprisingly difficult to photograph as they are really quite small.

The negative end of the charger for the AA and AAA batteries. When you look at the unit as a whole, the design really is quite ingenious. It is so compact yet can charge either 2 x 9 volt batteries or 4 x AA/AAA batteries at once. Or maybe I'm just showing my design-nerdiness just a little too much!!
