Main trade-off
EcoFlow DELTA 3 Plus
The 1,800W continuous inverter is lower than C1000 Gen 2 despite a similar 1kWh battery. X-Boost does not change that normal output limit.
Head-to-head
EcoFlow DELTA 3 Plus vs BLUETTI AC180: DELTA carries lighter, AC180 holds more energy beside a fixed load
The short answer
Choose DELTA 3 Plus for easier lifting and a two-input solar setup. AC180 suits longer use from the base battery beside a fixed appliance.
Before you choose
The reasoning and the trade-offs
A common load makes the reserve easier to compare
For a steady 300W load, EcoFlow DELTA 3 Plus models to about 2.7 hours and BLUETTI AC180 to 3.1 hours.
What this is based on
Hours = nominal Wh × 0.8 / 300W. Inputs 1024Wh and 1152Wh. The 80% factor is a shared planning allowance for unusable energy and conversion losses, not a measured efficiency. Idle draw, temperature and the real load change runtime.
Main trade-off
BLUETTI AC180
At about 35.27 pounds, it is substantially heavier than newer 1kWh models. It has only one USB-C port.

What matters in practice
The differences that matter
A common load makes the reserve easier to compare
For a steady 300W load, EcoFlow DELTA 3 Plus models to about 2.7 hours and BLUETTI AC180 to 3.1 hours.
How we reached this conclusion
Hours = nominal Wh × 0.8 / 300W. Inputs 1024Wh and 1152Wh. The 80% factor is a shared planning allowance for unusable energy and conversion losses, not a measured efficiency. Idle draw, temperature and the real load change runtime.
What you gain for each pound carried
EcoFlow DELTA 3 Plus stores about 37.1 nominal watt-hours per pound, compared with 32.7 for BLUETTI AC180.
How we reached this conclusion
Nominal energy divided by published weight: 1024 / 27.6 and 1152 / 35.27. This compares stored energy per lifting weight, not measured efficiency or handle comfort.
Twice the solar ceiling in a lighter cabinet
DELTA 3 Plus doubles the maximum combined solar intake while reducing carry weight by about 22% versus AC180.
How we reached this conclusion
1000 / 500 = 2. (35.27 - 27.6) / 35.27 × 100 = 21.7%. Reaching the DELTA total requires two compatible inputs.
Choice A
EcoFlow, DELTA 3 Plus
DELTA 3 Plus
A 1,024Wh station that puts fast solar recovery and high-power USB-C ahead of headline battery size. Two 500W solar inputs can feed separate panel strings.
- Best matched use
- Daily solar use and laptop-heavy backup
Checked facts
- 1,024Wh LFP battery and 1,800W rated AC output
- About 27.6 lb with two 140W USB-C ports and sub-10ms transfer
- Two 500W solar inputs with 11–60V windows and supported expansion to roughly 5kWh
Choice B
BLUETTI, AC180
AC180
A 1,152Wh station with four US AC outlets, a wireless charging pad and a 1,800W inverter. Its extra battery reserve comes with a notably heavier carry.
- Best matched use
- Stationary weekend power with four AC plugs
Checked facts
- 1,152Wh LFP battery and 1,800W rated AC output under stated temperature limits
- About 35.27 lb with four 120V outlets, 100W USB-C and a 15W wireless pad
- 500W solar input, 12–60V at up to 10A, and a 1,440W Turbo AC charging mode
Meaningful differences
What changes the fit
| What changes | EcoFlow DELTA 3 Plus | BLUETTI AC180 | Why it matters |
|---|---|---|---|
| Nominal battery energy | 1024 Wh | 1152 Wh | Stored energy determines the starting runtime budget. |
| Continuous AC output | 1800 W | 1800 W | This is the sustained rating used for load screening, separate from surge and boost modes. |
| Lifting weight | 27.6 lb | 35.27 lb | Wheels help on flat ground. A trunk, step or shelf still requires a lift. |
| Maximum solar input | 1000 W | 500 W | The panel voltage, current and per-port limits must also fit. |
| Dedicated battery expansion | Supported with compatible equipment | Fixed base capacity | Charging from an external source is different from integrated battery expansion. |
| Published transfer limit | 10 ms | 20 ms | Verify the exact connected device. A short transfer specification does not guarantee uninterrupted operation for every load. |
What you give up
Every choice has a cost
If you choose EcoFlow DELTA 3 Plus
- The IP65 rating covers the battery pack, not permission to operate the entire station in rain. Expansion batteries and alternator hardware are separate.
If you choose BLUETTI AC180
- BLUETTI limits continuous output to 1,500W in 86–104°F ambient temperatures. The 2,700W lifting mode is not a general continuous rating.
What matters in practice
How to make the call
The solar difference is larger than the battery difference
DELTA 3 Plus can accept 1,000W across two inputs versus 500W for AC180. AC180 has only 128Wh more battery capacity, so solar layout can matter more off grid.
A lighter carry comes with less stored energy
DELTA weighs 27.6 pounds against 35.27. The AC180 capacity gain is about 20 modeled minutes at 300W, which makes the carry penalty easy to judge.
Both stop at the same rated load
Each has 1,800W continuous output. Choose by runtime, charging and handling once your appliance fits that rating, rather than comparing boost-mode headlines.
What this comparison cannot tell you
- Runtime figures are planning estimates from published capacity, not hands-on discharge tests.
- Do not connect a station to home wiring without approved transfer equipment and qualified installation. A battery station is not a medical continuity guarantee.
