Some devices quietly sip power in the background, while others only come alive when you use them. Meet the energy vampires hiding around your home – from standby drainers to full-on daywalkers.
Standby Drainers
The classic vampires – seemingly “off”, but still quietly sipping electricity in the background.
TVs
Standby mode keeps them ready for the remote, updates and smart features.
Games consoles
Similar to TVs, can be put into standby mode for instant-on or background updates.
Desktop PC and monitors
Sleep mode still consumes electricity, particularly with several peripherals connected.
Printers
Especially WiFi printers that remain connected and waiting for jobs.
Chargers
Usually a tiny amount individually, but they’re commonly left plugged in permanently.
The Watchers
These aren’t really hiding what they’re doing – they’re designed to stay powered up so they’re ready whenever you need them.
Smart speakers
Alexa, Google Nest and similar devices are effectively always listening and connected.
Streaming devices with voice control
Stay partially powered so they can hear commands, update and wake up instantly.
WiFi routers, extenders and mesh systems
Technically not usually “off”, but they’re classic always-on household energy users.
Smart devices
Cameras, thermostats and hubs stay connected around the clock, constantly using a little power.
Video doorbells
Motion sensors, cameras and WiFi keep them working even when nobody’s at the door.
The Daywalkers
These aren’t usually draining much when they’re switched off, but when they spring into action they can demand a lot of power in a short space of time.
Kettles
Most basic kettles use virtually nothing once switched off, but smart kettles and models with keep-warm modes can keep drawing power in the background. Plus, the drain in use is a secret killer.
Microwaves
That glowing clock needs power 24/7.
Electric showers
They use no meaningful power while off, but demand a huge amount once the water starts flowing.
Hairdryers & straighteners
High heat means high power, even if they’re only switched on for a few minutes.
Air fryers
Powerful heating elements make them energy-hungry while cooking, though usually for a shorter time.
