BLUETTI AC180: the specifications, checked and calculated
The largest battery of the three. Below is every published figure for the BLUETTI AC180, each one linked to its source, plus runtime calculated from those figures with the arithmetic shown.
Specifications
| Battery capacity | 1,152 Wh |
| Chemistry | LiFePO4 |
| AC inverter | 1,800 W continuous, 2,700 W surge |
| Cycle life | 3,500+ cycles |
| Recharge | 0–80% in ~45 min; full in ~2 h (Turbo, 1440 W input) |
| Max solar input | 500 W |
| Weight | 37 lb (17 kg) |
| Dimensions | 340 × 247 × 317 mm (13.4 × 9.7 × 12.5 in) |
| Outlets | 4× AC (1800W total), USB-C, USB-A, 12V DC, wireless charging pad — 11 total |
| Warranty | 5 years |
What 1,152 Wh actually runs
Rated capacity is not usable capacity — the inverter takes a cut converting DC to AC. We work from ~979 Wh usable and divide by the real draw:
| Load | Draw | Calculated runtime |
|---|---|---|
| Full-size refrigerator (modern, Energy Star) | 150 W × 33% duty | 15 h |
| CPAP, no humidifier or heated hose | 30 W | 22 h |
| CPAP with humidifier + heated hose | 90 W | 9.3 h |
| Wi-Fi router + cable modem | 20 W | 28 h |
| Laptop (charging) | 60 W | 13 h |
| Box fan | 75 W | 11 h |
| Space heater (high setting) | 1500 W | 39 min |
These are calculated, not measured. Real results vary with temperature, battery age, and how hard the inverter is working. Treat them as a planning baseline, not a guarantee.
Details the spec sheet buries
- "Power Lifting Mode" is BLUETTI's equivalent of X-Boost: it reaches 2,700 W for resistive heating loads only (heaters, kettles, hair dryers). It will not start a motor rated above 1,800 W.
Where the manufacturer contradicts itself
BLUETTI's own AC180 page lists the weight two different ways: the spec card says 35.3 lb, while the product description says "weighs only 37lbs / 17kg". We quote the heavier figure, because 37 lb / 17 kg is the one given with a matching metric conversion. If you are buying on portability, assume the higher number.
How it compares to the others we cover
| Unit | Capacity | Output | Weight | Cycle life |
|---|---|---|---|---|
| BLUETTI AC180 (this page) | 1,152 Wh | 1,800 W | 37 lb | 3,500+ cycles |
| Jackery Explorer 1000 v2 | 1,070 Wh | 1,500 W | 24 lb | 4,000 cycles to 70%+ capacity |
| EcoFlow DELTA 2 | 1,024 Wh | 1,800 W | 27 lb | 4,000 cycles to 80%+ capacity |

Will it run a full-size refrigerator?
Yes. A modern full-size fridge draws about 150 W while the compressor is running, and the compressor runs roughly a third of the time. Against ~979 Wh of usable capacity that calculates to about 15 h. Starting surge is the other half of the question: the 2,700 W surge rating covers a standard domestic fridge comfortably.
Can I recharge it from solar during an outage?
Yes — it accepts up to 500 W of solar input. In good sun that is roughly 3.1 hours to refill from empty, allowing for real-world panel losses. Note that "good sun" is doing a lot of work in that sentence: panel output falls sharply with cloud, angle and heat.
Will it run a space heater or an air conditioner?
A 1,500 W space heater is right at the edge of the 1,800 W inverter, and it would flatten the battery in well under an hour. Resistive heating is the worst possible use of stored battery capacity. A window air conditioner is more realistic on paper, but the compressor surge is the deciding factor.
How current are these figures?
Every specification on this page was checked against the manufacturer's own documentation on 2026-07-29, and the sources are linked at the foot of the page so you can confirm them yourself. Manufacturers revise specs quietly and retailers copy old figures for years, so if you spot a discrepancy between this page and the source we cited, tell us and we will correct and re-date it.
