Can the BLUETTI AC180 Run a Chest Freezer?
Yes. With 1,152Wh of LiFePO4 battery capacity (979Wh usable after 85% AC inverter conversion) and a 1800W continuous / 2700W surge pure sine wave inverter, the BLUETTI AC180 should run a Chest Freezer / Deep Freezer (7–15 cu. ft.) for approximately 21.3 hrs on a single charge.
- Usable Watt-Hours: The BLUETTI AC180 holds 1152Wh, which yields about 979Wh of 120V AC power, assuming ~15% DC-to-AC inverter loss.
- Chest Freezer Duty Cycle: While active, a Chest Freezer pulls 120W (with a 550W startup spike). Over a multi-hour period, its 32% duty cycle averages ~38W per hour (plus ~8W inverter standby overhead).
- Tip: Chest freezers trap cold air at the bottom, making them 25% more energy-efficient than upright refrigerators. A 1,024Wh power station (like the EcoFlow DELTA 2 or Jackery 1000 v2) can keep a chest freezer frozen for 20+ hours continuously—or up to 48 hours if you cycle it on for 4 hours every 8 hours.
