The short answer
Phantom load is the 5-10% of your bill consumed by electronics in standby mode 24/7. The biggest offenders: cable box (25-40W), gaming console in instant-on (15-30W), networked printer (5-15W), surround receiver (10-30W). A $25 smart power strip eliminates 80% of phantom load on dependent outlets without behavioural change.
Phantom load — also called vampire load or standby power — is the electricity that idle electronics consume 24 hours a day. The Department of Energy estimates phantom load is 5-10% of a typical US residential bill, with high-end smart-home setups running closer to 15%. The biggest offenders are cable boxes (25-40W continuous), gaming consoles in instant-on mode (15-30W), networked printers (5-15W), and surround sound receivers (10-30W).
The top phantom-load offenders
Cable / satellite box: 25-40W continuous. The biggest single phantom-load device in most US homes. Annual cost: $40-65 per box.
Gaming consoles in instant-on / quick-resume: 15-30W continuous. PlayStation 5 and Xbox Series X both default to "rest mode" or "instant on". Annual cost: $25-50 per console.
Networked printer: 5-15W continuous if Wi-Fi is enabled. Annual cost: $8-25 per printer. Surround receiver / stereo: 10-30W continuous if "auto-on" or HDMI-pass-through is enabled. Annual cost: $15-50.
- Cable box: 25-40W → $40-65/yr
- Gaming console (instant-on): 15-30W → $25-50/yr
- Networked printer: 5-15W → $8-25/yr
- Surround receiver: 10-30W → $15-50/yr
- Digital displays + chargers + everything else: 1-3W each
Smart strips eliminate 80% of phantom load
A smart power strip ($20-40) has a "master" outlet and 4-6 "dependent" outlets. When the master device powers down (TV turns off), the strip cuts power to the dependent outlets.
Wire it like this: TV plugs into master outlet. Cable box, sound bar, gaming console plug into dependent outlets. Wi-Fi router and DVR plug into "always-on" outlets.
For home offices: monitor as master, computer / printer / desk lamp as dependents. The home-energy-monitor-emporia-sense guide covers tools to measure phantom load directly.
Gaming console settings — quick win
PlayStation 5: Settings → System → Power Saving → set short window then disable "Stay Connected to the Internet" if you do not need remote download.
Xbox Series X / S: Settings → General → Power Mode → switch from 'Standby' to 'Energy Saver'. Boot time goes from 6 seconds to 45 seconds, but standby draw drops from 25W to under 1W.
Annual savings per console: $20-40. Configuration time: 30 seconds per console. Top phantom-load ROI in any household with gaming hardware.
Recap
Bottom line
Phantom load is the silent compounder of every US household electric bill. The Department of Energy estimates 5 to 10 percent of a typical residential bill goes to electronics in standby mode 24/7. On a $163/month bill that is $8 to $16 per month — $96 to $192 per year — for stuff that is not even being used.
The fix is mechanical: smart power strips on entertainment center clusters, energy-saver mode on gaming consoles, and unplug rarely-used chargers. For households with multiple gaming consoles, cable boxes, and networked devices, the savings can reach $100 to $250 per year for under $100 of one-time hardware investment.
