Devices and assumptions
| Device | Qty | Hours a day | Running | Starting | Source |
|---|---|---|---|---|---|
| Mini fridge/cooler | 1 | On the whole time | 75 W | 500 W | ENERGY STAR data + Champion chart · cycles about 37% of the time calculated |
| String lights / LED camp lights | 1 | 4 | 125 W | No extra | Champion wattage chart |
| Phone or laptop charger | 1 | 2 | 60 W | No extra | Champion wattage chart |
Together: 260 W running, about 685 W while the largest motor starts, and 1,288 Wh a day. Over the 48-hour goal that is 2,577 Wh at the outlet calculated.
- The mini fridge uses the median ENERGY STAR compact-refrigerator figure; electric coolers vary widely.
- Camp lights use the Champion chart midpoint for string lights.

What would change this answer
- Your own device watts: the label on the device beats any typical figure. Enter it in the calculator.
- Inverter idle draw: most makers don't publish it, so hours here leave it out. Small loads feel this most.
- Cold: below a maker's temperature range a station may stop discharging or charging.
- Solar: with 100 W of panels, the DELTA Pro 3 refills from empty in about 55 h of good sun calculated.
Our take
The fridge is most of the energy on a camping weekend. If you use a 12 V compressor cooler from the car port instead of an AC mini fridge, you skip the inverter and need less battery.
