BLUETTI AC180
At about 35.27 pounds, it is substantially heavier than newer 1kWh models. It has only one USB-C port.
Head-to-head
BLUETTI AC180 vs EcoFlow DELTA 3: DELTA carries lighter and expands, AC180 starts with more reserve
The short answer
Choose DELTA 3 for a lighter carry, expansion and faster transfer. The AC180 gives more built-in energy when it stays beside the load.
Before you choose
The reasoning and the trade-offs
A common load makes the reserve easier to compare
For a steady 300W load, BLUETTI AC180 models to about 3.1 hours and EcoFlow DELTA 3 to 2.7 hours.
What this is based on
Hours = nominal Wh × 0.8 / 300W. Inputs 1152Wh and 1024Wh. 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
EcoFlow DELTA 3
One 500W solar input cannot make use of the Plus model 1000W two-input setup.

Winner by situation
Start with what you need it to do
Run a fixed load for a little longer
The AC180 adds 128Wh, but DELTA 3 cuts 7.67 pounds. For a 300W desk setup, the modeled gain is around 20 minutes, not several more hours.

- Depends
Carry the station regularly
DELTA 3 weighs 27.6 lb against 35.27 lb for AC180. That saves 7.67 lb on every lift, with about 20 fewer modeled minutes at a steady 300W load.

The battery needs to cover a steady 300W load
The shared planning case gives 3.1 hours from BLUETTI AC180 and 2.7 from EcoFlow DELTA 3. Measure actual wattage before choosing a required overnight reserve.

What matters in practice
The differences that matter
A common load makes the reserve easier to compare
For a steady 300W load, BLUETTI AC180 models to about 3.1 hours and EcoFlow DELTA 3 to 2.7 hours.
How we reached this conclusion
Hours = nominal Wh × 0.8 / 300W. Inputs 1152Wh and 1024Wh. 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
BLUETTI AC180 stores about 32.7 nominal watt-hours per pound, compared with 37.1 for EcoFlow DELTA 3.
How we reached this conclusion
Nominal energy divided by published weight: 1152 / 35.27 and 1024 / 27.6. This compares stored energy per lifting weight, not measured efficiency or handle comfort.
The lighter station gives up only one ninth of capacity
DELTA 3 removes about 22% of the AC180 weight while giving up about 11% of its nominal battery capacity.
How we reached this conclusion
(35.27 - 27.6) / 35.27 × 100 = 21.7%. (1152 - 1024) / 1152 × 100 = 11.1%.
Choice A
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
Choice B
EcoFlow, DELTA 3
DELTA 3
The expandable DELTA 3 for buyers who do not need the Plus model extra solar input. The battery and inverter are the same size, so the simpler charging setup can be entirely sufficient.
- Best matched use
- Home essentials and camping loads with a moderate solar array.
Checked facts
- 1024Wh battery and 1800W rated AC output.
- About 27.6 lb.
- One 500W solar input with an 11V to 60V range.
- Two 100W USB-C ports and six AC outlets.

Meaningful differences
What changes the fit
| What changes | BLUETTI AC180 | EcoFlow DELTA 3 | Why it matters |
|---|---|---|---|
| Nominal battery energy | 1152 Wh | 1024 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 | 35.27 lb | 27.6 lb | Wheels help on flat ground. A trunk, step or shelf still requires a lift. |
| Maximum solar input | 500 W | 500 W | The panel voltage, current and per-port limits must also fit. |
| Dedicated battery expansion | Fixed base capacity | Supported with compatible equipment | Charging from an external source is different from integrated battery expansion. |
| Published transfer limit | 20 ms | 10 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 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.
If you choose EcoFlow DELTA 3
- USB-C is limited to 100W per port rather than 140W.
What matters in practice
How to make the call
Capacity and portability pull in different directions
The AC180 adds 128Wh, but DELTA 3 cuts 7.67 pounds. For a 300W desk setup, the modeled gain is around 20 minutes, not several more hours.
Transfer time is a separate requirement
The published 20ms versus 10ms limits favor DELTA 3 for equipment with a short hold-up time. Neither figure is a promise that every computer will stay running.
Solar wattage does not split this pair
Both list 500W maximum solar input. Panel voltage, current, connector and cold-weather open-circuit voltage must still match the exact input.
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.
