Devices and assumptions
| Device | Qty | Hours a day | Running | Starting | Source |
|---|---|---|---|---|---|
| Freezer | 1 | On the whole time | 300 W | 750 W | ENERGY STAR data + Champion chart · cycles about 8% of the time calculated |
Together: 300 W running, about 750 W while the largest motor starts, and 597 Wh a day. Over the 48-hour goal that is 1,195 Wh at the outlet calculated.
- Freezer energy is the median of the ENERGY STAR chest-freezer listings (a small sample).
- Starting watts are the midpoint of the Champion chart range for a freezer.

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.
Our take
Chest freezers use little energy per day once cold, so two days is within reach of mid-size stations. The ENERGY STAR chest-freezer sample is small, so treat the daily energy as a rough guide and check the EnergyGuide label on your own freezer.
