Source-aware comparison

EcoFlow DELTA 2 vs BLUETTI AC180

A source-backed comparison with neutral, spec-derived verdicts. Unknown fields stay visible, and both stations use the same runtime assumptions.

Compare this pair for a real load

Scenario pages apply one source-backed device load to both stations before you inspect the full table.

Full-size refrigerator

Uses 500 W and 33% duty cycle for both stations.

EcoFlow DELTA 2

1,024 Wh, 1,800 W AC output.

Lifecycle status: Unknown. Confidence: Verified. Last verified: 2026-06-24.

BLUETTI AC180

1,152 Wh, 1,800 W AC output.

Lifecycle status: Unknown. Confidence: Verified. Last verified: 2026-06-24.

Capacity

Capacity: AC180 is higher by 128 Wh.

AC Output

AC output: both records are equal at 1,800 W.

Solar Input

Solar input: both records are equal at 500 W.

The 60 W runtime estimate assumes AC output, 85% conversion efficiency, and 10% battery reserve. It is a sanity check, not a lab-tested result. This label describes availability in the cited region only. It does not imply that another model is universally better, compatible, or an official replacement.

Which one, when?

These verdicts are computed only from tracked specs. They do not use price, affiliate status, ads, sponsorships, or untracked preferences.

Best for longer runtime margin

BLUETTI AC180 leads this tracked field: 1,152 Wh vs EcoFlow DELTA 2 at 1,024 Wh (+128 Wh).

Best for portability

EcoFlow DELTA 2 leads this tracked field: 12 kg vs BLUETTI AC180 at 16 kg (+4 kg).

Planning Watch-Outs

These checks explain where the comparison is strong and where it still needs better source coverage.

5 of 5 high-impact comparison fields are filled on both sides.
AC180 has the larger nominal battery capacity, but usable Wh still depends on reserve, efficiency, temperature, and battery age.
DELTA 2 is lighter in the tracked weight data, which matters if the station is moved often.
DELTA 2 has the higher tracked solar input, assuming compatible panels and charge-voltage limits.
