What devices use the most phantom load power?

Cable boxes, DVRs, entertainment centers, always-on chargers, and some smart home hubs are usually the biggest phantom load offenders. A single entertainment stack can waste $20 to $50 per year on standby energy alone.

Do smart plugs stop standby power?

Yes. Smart plugs and smart power strips can fully cut power to devices on a schedule or by app control, which stops standby energy use instead of just measuring it.

How much can you save by fixing vampire power?

Most homes can save about $80 to $150 per year by targeting the biggest phantom loads first. Homes with multiple entertainment centers, game consoles, cable boxes, and chargers can save even more.

Vampire Power FAQ

What is vampire power?

Vampire power is the electricity your devices use while they appear off but stay in standby mode. TVs, cable boxes, chargers, speakers, and consoles can all keep drawing power 24/7 unless you cut the outlet completely.

What uses the most phantom load power?

Entertainment centers, cable boxes, DVRs, chargers left plugged in, and always-on smart home hubs are the usual top offenders. They are the first places to audit if you want the fastest standby energy savings.

Do smart plugs actually stop standby power?

Yes. A smart plug or smart strip can fully cut power on a schedule or by command, which stops standby draw instead of only tracking it.

How much can vampire power cost each year?

Most homes waste about $80 to $150 per year, and homes with multiple entertainment stacks or older cable boxes can waste more. That is why a low-cost smart strip often pays for itself in a few months.
