I use a Braun rechargeable toothbrush and a Panasonic razor which both use this induction chageing method and they have charged fine for over two years without any damage - BUT - I do it from a bathroom 12v razor box that chandlers supply. Perhaps they are a better option? The box buzzs when in use and gets warm after 12 hours or so I do unplug when charged.
I wonder if the power drawn by small rechargeable items is enough to kick a big inverter into life anyway?
