Goal Zero Yeti 700 vs BLUETTI AC70

A starter comparison that keeps unknown fields visible and uses the same runtime assumptions for both stations.

Goal Zero Yeti 700

677 Wh, 600 W AC output.

Confidence: verified. Last verified: 2026-06-24.

BLUETTI AC70

768 Wh, 1,000 W AC output.

Confidence: verified. Last verified: 2026-06-24.

Capacity

Capacity: AC70 is higher by 90.63 Wh.

AC Output

AC output: AC70 is higher by 400 W.

Solar Input

Solar input: AC70 is higher by 300 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.

Runtime Examples

Same assumptions on both sides: AC output, 85% efficiency, 10% reserve, healthy battery, and steady load.

Example load	Yeti 700	AC70
60 W AC essentials	8h 38m	9h 48m
120 W AC small appliance	4h 19m	4h 54m
700 W AC kitchen or tool load	above AC rating	50m

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.
AC70 has the larger nominal battery capacity, but usable Wh still depends on reserve, efficiency, temperature, and battery age.
Yeti 700 is lighter in the tracked weight data, which matters if the station is moved often.
AC70 has the higher tracked solar input, assuming compatible panels and charge-voltage limits.
