How Much Does It Cost to Charge an Anker SOLIX F3800?

Calculate the grid recharge cost for the 3,840Wh Anker SOLIX F3800 using current EIA electricity prices and a transparent efficiency assumption.

The SOLIX F3800 stores 3,840Wh nominally. A full grid recharge therefore draws more than 3.84kWh once charging losses are included.

What matters

  • Anker lists 3,840Wh nominal capacity for the F3800.
  • At 90% efficiency, a full refill uses about 4.27kWh from the wall.
  • State electricity rates create a larger percentage spread than small efficiency differences.
  • Daily or weekly cycling is better modeled with monthly and annual charging cost.

How to size it

  1. Convert 3,840Wh to 3.84kWh.
  2. Divide by charging efficiency.
  3. Multiply by cents/kWh converted to dollars.
  4. Scale by partial state-of-charge change when appropriate.
Worked sizing logic

At 18.16¢/kWh and 90% efficiency, a full nominal recharge costs about $0.77. Using EIA state averages, the same refill is roughly $0.52 in North Dakota and $1.96 in Hawaii.

Common buying mistakes

  • Assuming 3.84kWh at the battery equals 3.84kWh from the meter.
  • Ignoring time-of-use rates.
  • Using charge cost as a proxy for battery economics.
Verdict

Even a large F3800 is inexpensive to recharge from the grid; system economics are driven primarily by hardware, cycling and what backup energy replaces.

Use your actual tariff when possible

State averages are useful for comparison, but the best charging-cost estimate comes from your own cents-per-kWh rate, the percentage of battery being restored and a realistic charging-efficiency assumption.
