You’ve heard it: “Unplug stuff when you’re not using it.” Annoying… but not wrong. The trick is to be strategic, not obsessive.
What’s “vampire power”?
Also called phantom load or standby power, it’s the electricity devices sip while “off” or idle—anything with a clock, status light, remote readiness, or sleep mode.
Usual suspects
-
Cable box/DVR: 20–30 W
-
Game console (rest mode): 10–15 W
-
Desktop (sleep): 5–21 W
-
Microwave (clock): 3–7 W
-
Phone/laptop chargers (plugged in, not charging): 0.1–1 W
Does it really add up?
For a typical home, standby is ~5–10% of usage—often $50–$150/year. In gadget-heavy homes, it can be more.
What not to unplug
Leave always-on essentials alone: fridge, modem/router, smoke/CO alarms, security systems, medical devices, smart-home hubs (if you rely on automations).
The lazy, high-impact plan
-
Put entertainment centers on a smart strip
The TV stays “control,” and the strip cuts power to peripherals (soundbar, console, streaming box) when the TV turns off. One click = whole stack asleep. -
Kill “rarely used + high draw” gear
Think treadmill screen, stereo in the guest room, spare printer, garage beer fridge (add a smart plug/timer if you must keep it). -
Tame consoles & PCs in settings
-
Consoles: disable “instant-on,” enable energy saver.
-
PCs/Macs: shorten sleep timers; disable “wake for network access” if you don’t need it.
-
-
Use smart plugs/timers
Lamps, fans, space heaters, holiday lights—schedule OFF overnight or when you’re away. Bonus: phone control. -
Unplug chargers
Trivial per charger, but easy habit + less outlet clutter/heat.
Want proof? Measure it.
Grab a plug-in energy monitor (Kill A Watt–style). Check in-use vs. standby for each device. You’ll quickly see which vampires deserve a stake through the heart (and which aren’t worth chasing).
