im having all this trouble because i have 6v 3,7w solar panel. i want to feed usb charger (5v), nimh charger (5,6v to charge 4nimh's) and lipo charger (4,2v) up to 500mA each(max even because this solar panel cant give to much more). not at the same time ofcourse. is it worth all this trouble find adjustable low drop converter or a step down buck converter would the job better? they dont have voltage drop right? and so what happens to current? small waste or big? thank you
