In Spain this summer, we bought an 800w inverter, not the most expensive pure sine wave type (whatever they are) to charge the batteries on our electric bikes; perfect!
As there was plenty of power available, I could not resist charging my little electric toothbrush. Big mistake! Apparently the shape of the sine wave does matter, well it did to my toothbrush, it destroyed it. ( later I read in the small print that this could happen)
