Worked example · Two days

Weekend camping: fridge, lights and laptop

A two-day camping energy budget for a compressor fridge, camp lighting and three hours of laptop use each day.

3 device types20% extra energy marginWithout recharging

Quick answer

Battery target for 2 days

2,655Wh

Stated battery capacity, including a 20% extra energy margin on demand and 80% usable energy.

Adjust this example

The example consumes about 885Wh per day. Two battery-only days exceed the 1kWh- and 2kWh-class stations, while the documented 3kWh- and 4kWh-class candidates can cover the full conservative target.

Energy per day: 885 Wh
Power check: 113 / 210 W
Solar target: 300 W

Solar is a separate estimate. The battery target is calculated without intermediate recharging.

Shortlist first

Stations to compare first

We check both battery size and whether the station can handle the load. Solar compatibility is still a separate check.

4 of 19 meet the target

First models that meet both the battery and power target, then the longest calculated coverage. No ranking on price or portability.

Total for one day885 Wh

Useful tip 1

Pre-cooling is stored energy

Cool the fridge and contents before departure where possible. Warm contents on arrival can keep the compressor running much longer.

Useful tip 2

Measure shade at the campsite

Four and a half peak-sun hours is an input, not a promise. Trees, panel angle and clouds can make the real day much weaker.

Calculation detailsSee the assumptions behind this answer

The fridge’s 45W compressor is represented by a 50% daily duty cycle
Camp lights total 25W for six hours
Laptop averages 65W for three hours
Solar planning uses a 75% yield rather than panel nameplate output

How the battery target is formed

885 Wh per day × 2 days × 1.2 ÷ 0.8 ≈ 2,655 Wh

The daily consumption above is rounded for display. The calculation uses unrounded values. The factor is 1 + the extra energy margin, added to demand rather than kept as battery charge; the 80% usable-energy allowance is a separate factor.
