About Standby Power Aggregator

Standby power formula

Daily kWh = Σ (standby W × quantity × 24 h) ÷ 1,000. Annual cost = daily kWh × 365 × your $/kWh rate. Modern devices draw watts even when screens are off—chargers, converters, and instant-on TVs are common culprits.

Cut phantom load

Smart strips and switched outlets can eliminate most always-on draw. Pair this audit with Smart Thermostat Savings for HVAC waste and LED Savings ROI for lighting upgrades.

Frequently asked questions

Q: Is standby worth fixing? A: One charger is pennies; a dozen devices add up to real money. Q: How accurate are defaults? A: Override watts with a plug meter for best results. Q: vs. Vampire Power Cost? A: Same math—this tool aggregates a whole-home list in one view.
