Too good to be true. Actually, the advertised function of these devices is a bit hard to tie down. The fact is, most electronic devices already have a voltage "stabiliser" built in to their design. e.g. In the power supply that regulates the main battery to 5 and 12 volts required by most of the peripheral electronics. The individual components that are responsible for the stabilisation are dirt cheap.
The advertised stabilisers have 2 leads... I wonder what's in the fancy box?

- I always thought that understanding preceded wisdom.
Yeah, my thought was that there was already voltage regulation being taken care of internally by the alternator. I know that some older vehicles have separate voltage regulators, like the 1989 Taurus I used to own...
