BLUETTI AC180
The AC180 is a roughly one-kilowatt-hour, 120 V portable battery with 1,800 W continuous output and a documented UPS switching figure of 20 ms or less. Its slightly higher nominal capacity than the DELTA 2 comes with a heavier listed base-unit weight and no directly attached expansion capacity verified in this source record. It remains an older-model alternative to Elite 100 V2.

Is it right for your household?
Selected 120 V essentials with verified running and startup requirements.
Frequent trips upstairs or a lighter carrying requirement.
More fit considerations
Other situations to consider
- A one-unit plan where base capacity matters more than frequent carrying.
- Equipment whose transfer requirements you can verify and test safely.
Other reasons to choose a different setup
- A plan that depends on directly attached battery expansion.
- 240 V loads or a whole-home backup installation.

More nominal Wh does not mean more output watts
The AC180 record lists 1,152 Wh, compared with 1,024 Wh for the DELTA 2, while both list 1,800 W continuous AC output and 2,700 W surge. The Wh values describe nominal stored energy; the watt ratings describe output limits. That modest capacity difference does not promise a particular extra runtime, and the shared output ratings do not guarantee either unit can start a specific appliance. Account for conversion loss, reserve, temperature, battery condition, and cycling loads, and check the actual appliance requirements.
Plan for the unit's weight and footprint
The listed base-unit weight is 35.27 lb, compared with 27 lb for the DELTA 2. Consider who may need to move it, where it can be stored safely, and how cables reach the equipment. The weight comparison does not include packaging or separately carried charging gear. Confirm the current US model and handling instructions in the product page and manual.
Interpret the switching figure carefully
The cited manual lists UPS switching at 20 ms or less and instructs readers to test UPS behavior where data loss is a risk. This figure is not a guarantee that every refrigerator, computer, medical device, or motor will ride through a transfer. Check the connected device's tolerance and follow both manufacturers' instructions before relying on pass-through backup.
Expansion and charging need their own verification
No directly attached expansion capacity was verified in the US manual used for this record. Do not plan on add-on battery runtime unless current manufacturer documentation confirms a compatible configuration. The record lists up to 500 W solar input, which is an input ceiling; actual charging depends on compatible equipment, conditions, and available sunlight. Verify connector, voltage, current, and charging limits before assembling a setup.
Check voltage, loads, outlets, and warranty
This US record lists 120 V output, four AC outlets, and a five-year warranty. Listing titles and illustrations can disagree about outlet counts; confirm the actual US unit’s outlet configuration with the seller. Confirm the exact model, the number and type of connections your plan needs, the running and startup demand of each load, and current warranty terms. Do not treat a high-power mode or surge figure as permission to exceed the appliance or station's documented operating limits.
