Bidirectional EV Charging: V2H vs V2L in Watts, kWh, and When It Beats a Home Battery

V2L, V2H, and V2G are not the same thing in practice. This guide turns marketing labels into real AC watts, realistic backup duration, and honest limits alongside whole-home storage.

Home Electricity Monitoring: Whole-Home CT Meters vs Circuit-Level, Accuracy, and What to Do With the Data

Before you buy labels like “AI insights,” decide what you are actually measuring. Compare whole-home monitoring on mains CTs to panel-level and plug-level approaches, and turn readings into kWh you can use for bills, backup, and solar.

How Many Watts Does a Box Fan Use? Sizes, speeds, and overnight kWh (2026)

A box fan is a small motor moving a big grille of air: tens of watts on low, often under ~100 W on high for a 20-inch. Here is how speed, filter hacks, and modified inverters change the numbers for bills and backup.

How Many Watts Does a Ceiling Fan Use? AC vs DC motors and light kits (2026)

Ceiling fans are low-watt air movers: many AC-motor models sit in the tens of watts on high; DC/EC motor fans often go lower with more speed steps. Add the light kit honestly—then kWh and inverter math are simple.

How Many Watts Does a Central Air Conditioner Use? Tonnage, LRA, and kWh (2026)

Central AC is often the largest summer kWh: outdoor compressor and fan plus an indoor air handler, not one sticker. Here is RLA and LRA in plain terms, why surge can dwarf running W, and how ballpark tables compare to your nameplate.

How Many Watts Does a Clothes Dryer Use? Electric, gas, and heat-pump (2026)

The dryer is often the heaviest laundry load on the panel: 240 V resistive heat on a standard electric unit, a small 120 V plug on many gas models, and a long lower-W heat-pump cycle. Nameplates, breakers, and minutes set kWh.
