Planning assumptions for the AC path. Battery reserve is charge left unused; idle draw is the station’s own consumption. Other tools on this site can start from different defaults. Actual losses depend on the station and load. Charging during use is not included.

What does more capacity give you?
One set of assumptions. One time scale. The marker shows your target.
Local model checks remain open. Use the calculated energy target, then compare the source-region capacity references in the full runtime chart. No Nigerian SKU has yet passed the model and photograph checks.
What should I check before buying?
- Normal and starting power, including peak duration. An average alone cannot prove compatibility.
- Your local voltage, frequency, outlet, cable and exact model version.
- Actual consumption varies with temperature, battery condition and load. Test critical equipment on the exact setup.
Not sure about the wattage?
A measurement often tells you more than the maximum rating on a label.

Runtime and connection compatibility are two separate questions.
