BLUETTI AC180P vs EcoFlow DELTA Pro
Technical comparison · Home backup
Two home batteries of different size: BLUETTI AC180P (1.44 kWh, 16 kg) is carried by hand from room to room, EcoFlow DELTA Pro (3.6 kWh, 45 kg, wheeled) mostly stays where it is and delivers more. What decides it is how many watts you need at the same moment, 1800 or 3600 (manufacturer-declared values).

The differences that matter
- 1.44 kWh vs 3.6 kWh → a 1000 W load runs about an hour and a half on the first, three and a half hours on the second.
- 1800 W vs 3600 W continuous → two kitchen appliances together exceed the smaller unit's limit; the larger one carries them.
- 500 W vs 1600 W solar input → with full sun and matching panels, a full recharge takes about three hours against a little over two.
- UPS (20 ms) vs EPS (30 ms) → the second cuts power for an instant when the mains drops; a sensitive device may notice.
Which one to choose
Choose BLUETTI AC180P if…
you want a UPS-style backup for a desk or for moving between house and garage, with a router, a laptop and a small fridge that stay under 1800 W. With a 500 W solar input, charging is slow and a 1000 W load lasts an hour and a half at best; in return it works down to -20 °C and carries a five-year warranty.
Choose EcoFlow DELTA Pro if…
you need more than 1800 W at once, for example two kitchen appliances together, or you plan to connect up to 1600 W of panels; the battery is also expandable. The price is weight: 45 kg, wheels or not, is not something you load into a car every week; the switch to backup has a brief pause (30 ms) and the warranty is three years.
