Battery Recharge Cost by State

Estimate battery recharge cost by state. The formula is recharge cost = battery capacity (kWh) × electricity price per kWh. Electricity prices vary widely by state, so recharge cost does too.

Why it varies by state: A 13.5 kWh home battery costs about 3× more to recharge in Hawaii than in Idaho because electricity rates differ. Select a state to see estimates for portable, backup, and home battery sizes.

Rates come from EIA data. All figures are build-generated and deterministic.

Standard Battery Size Examples

We use three common battery capacities for estimates:

  • 1 kWh portable battery — power banks, small backup
  • 5 kWh backup battery — partial home backup
  • 13.5 kWh home battery — whole-home backup (e.g. Tesla Powerwall)
