How long will a Jackery 2000 run a refrigerator?

A Jackery 2000 (assumed to be a 2,000Wh model) can power a standard refrigerator for approximately 10–18 hours, depending on the fridge’s energy draw. Most household refrigerators consume 100–200W when running, but cycle on/off to maintain temperature. For example, a 150W fridge running 50% of the time would deplete the 2,000Wh battery in ~13 hours. Actual runtime varies with ambient temperature, insulation quality, and door openings.

What factors affect runtime?

Fridge wattage, battery efficiency, and usage patterns dictate runtime. A 120W fridge with a 90% efficient inverter draws ~133W (120 ÷ 0.9), reducing total runtime to ~15 hours. Pro Tip: Use a Kill-A-Watt meter to measure your fridge’s actual consumption.

Refrigerators don’t run continuously—they cycle compressors to maintain temperature. If your fridge operates 60% of the time (e.g., in hot climates), a 2,000Wh battery lasts ~10 hours (2,000Wh ÷ [150W × 0.6]). Transitionally, battery chemistry also matters: lithium-ion handles deeper discharges than lead-acid. But what if you’re opening the door frequently? Expect 20–30% shorter runtime due to thermal loss. For example, a 12V camping fridge drawing 75W could run ~26 hours on a Jackery 2000.

How does ambient temperature impact performance?

Heat increases compressor cycles, while cold reduces battery efficiency. Lithium batteries lose ~15% capacity at 0°C.

In a 30°C environment, fridge compressors work harder, increasing runtime drain by 25–40%. Conversely, using the Jackery in freezing conditions forces its BMS to divert power to self-warming circuits. Practically speaking, a fridge in a shaded 20°C garage might achieve 18 hours, while the same setup in direct sun drops to 12 hours. Pro Tip: Pre-chill the fridge before switching to battery power—this reduces initial compressor load.
