Plan Portable Power for a Weekend Camping Trip
Turn a camping equipment list into an energy plan while keeping refrigeration, connection routes, and solar assumptions honest.

Start with the trip window
Use the actual trip duration and enter active hours within that window. For a fridge, a measured 24-hour energy value is usually more useful than assuming it draws its label wattage continuously. Add lighting, phones, cameras, fans, and pumps as separate rows.
Check both energy and output. A compressor start can be important even when daily energy looks modest. DC connection voltage and current limits also matter; a matching watt figure does not guarantee a suitable connector.
Treat solar as a possible energy input, not guaranteed replacement energy. Cloud, shade, orientation, heat, charge taper, and campsite rules can alter the result. Keep enough reserve for the plan even if charging underperforms.
Separate continuous and occasional loads
Cooling often runs across the whole trip but cycles with temperature and thermostat behavior. Lights, cameras, phones, pumps, and cooking accessories may run briefly. Enter each separately so the result shows what dominates the energy budget and which route adds conversion overhead.
For a 48-hour trip, a measured 24-hour fridge energy figure is scaled by two. Do not also multiply that value by 48 hours or apply a duty cycle—the daily reading has already captured time and cycling. If you only know on-cycle watts, use operating watts, total active hours, and a defensible cycling fraction instead.
Record quantity carefully. Charging two phones is not always twice a charger’s maximum rating; use energy or average readings that describe the actual sessions where possible. Likewise, a light advertised by “equivalent” brightness should be entered using its electrical input watts, not the incandescent-equivalent number.
Choose routes before choosing capacity
An AC appliance keeps its normal adapter but requires the station’s inverter. Compatible direct DC or USB operation may reduce conversion and idle overhead, yet it introduces connection constraints. Confirm voltage, current, polarity, protocol, shared limits, and cable suitability. A plug that fits is not sufficient evidence.
If AC is used only occasionally, set AC-enabled time to the period the inverter will actually be on. Do not set it shorter than the declared AC use. The estimate adds idle draw separately so a small AC load left enabled for an entire weekend is not treated as free.
Make three versions of the trip
Create a baseline plan for expected use, a low-energy plan containing only essential loads, and a no-solar plan. These are scenarios, not confidence intervals. They reveal decisions you control if the trip lasts longer or charging is poor.
When solar is considered, run it through the separate solar estimator. Its “equivalent steady-input hours” are not elapsed clock time. The daily view uses an editable peak-sun-hours assumption and subtracts a 24-hour concurrent load; it does not fetch weather or approve an electrical connection.
Before departure, compare the selected station’s continuous output, startup information, and port details with the actual equipment. Capacity alone is not a compatibility result, and an expansion battery does not automatically increase inverter output.
