It's great for use as a fan controller for laptop external fan cooling, especially.
Thumbs up, ibxoful.
last time i checked the voltage was way above it was rated,get to its rated voltage when under load, that again its still not a fix voltage, i don't think a fan loads the adapter enough to make it work on its rated voltage
