These energy saver gizmos are great for combating "vampire energy" wastage all the wall wart style chargers we all use.
Have you ever noticed how warm they get even when your phone/tablet/computer/pencil sharpener/whatever isn't plugged in? That's "energy" being wasted warming the iron core of the transformer. Nowadays we have so many of these power supplies that it really adds up on your energy bill.
Smart surge protectors can tell when those transformers are really doing work (like charging your phone) and when they're just being vampires. They shut off the offending plugs until the demand is actually needed again.
