01 · Load manifest
Average draw applies each sourced duty cycle; energy is average draw × quantity × daily hours × scenario days.
| Device | Quantity | Hours / day | Average draw | Scenario energy | Source |

02 · Reading the plan
Half of this day is not consumption at all. Of 1,256 Wh, some 630 Wh is transfer — three drone charges at 390 Wh and two camera batteries at 240 Wh, energy moving sideways out of one cell and into another — while the remaining 626 Wh is the laptop doing actual work. That distinction is what makes this plan behave oddly: transfer is counted in charges and work is counted in hours, and only one of the two grows with how long you stay out.
Planning around the laptop and being surprised by the batteries. The laptop is the single heaviest line and it is also the one device on the plan, so it gets the attention. But a drone charge is 130 Wh, an hour of the laptop under sustained load is 104 Wh, and a fourth flight therefore costs more than an extra hour at the keyboard. On most manifests one line dominates and the rest is noise; here the flying and the editing cost roughly the same per unit, and you have to count both.
Every figure here is measured going into a charger, not arriving in a cell. A pack that accepts 130 Wh through its charger has stored less than 130 Wh, the difference is heat in the charger and heat in the pack, and no manufacturer publishes it — so these numbers are right about what the station spends and silent about what you get back. The second gap is the calendar: this manifest bills three charges every day because the sizing model works in days, when a drone battery is a per-flight cost. The two-day total is a shooting schedule we invented, not a duration anyone can promise you.

Solar balance
On EcoFlow DELTA Pro Ultra X, the configured 200 W array harvests 560 Wh/day.
The remaining deficit is 918 Wh/day, for about 13.4 days of modeled runtime.
