Goal Zero Yeti 300 is a ultraportable / carry model best suited to camper. It supplies 350 W of continuous AC output. Its current tracked price is $349.95; there is not enough tracked history for a verdict. BatteryRank scores it 71 out of 100 within its size class.
Capacity truth

What it can run
Same sourced device assumptions used by our calculators, applied to this model's usable AC energy. Actual runtime varies with load, temperature, and standby draw.
| Device | Estimated runtime | Sourced assumption |
|---|---|---|
| CPAP (humidifier off) | about 3.2 nights | 9 W · |
| CPAP (heated humidifier on) | about 0.5 nights | 56 W · |
| Refrigerator (full-size) | about 3.6 hours | 180 W × 35% duty cycle · |
| Wi-Fi router + modem | about 13 hours | 18 W · |
| Laptop (65W charger) | about 7.0 hours | 65 W × 50% duty cycle · |
| Phone (one full charge) | about 11 full charges | 20 W · |

How this score is computed
The BatteryRank score is computed from sourced data with a published formula — ranked by data, not lab testing. Seven sub-scores blend into a 0–100 composite, grouped into four buyer pillars. Price is deliberately not a scoring input: prices move daily, so value intelligence lives in the price section above, judged against this model's own history.
| Pillar | Built from |
|---|---|
| Power | Capacity & expansion + Output & versatility |
| Trust | Trust & reliability + Durability & longevity |
| Charging | Charging & solar |
| Livability | Portability + Quiet / livability |
Scores are cohort-relative — each model is ranked against others in its size class. Missing inputs renormalize out rather than scoring zero (a model is never penalized for a spec nobody in its class publishes), and any figure resting on a documented estimate is tagged est.

How many full charge-and-drain cycles before the battery drops to its rated threshold (shown alongside — brands rate to different thresholds, so never compare bare cycle counts).
The type of battery cell. LiFePO4 (LFP) cells last far more cycles and are more thermally stable than older lithium-ion (NMC) cells.
The battery's nameplate energy capacity — the headline number on the box. Battery-side usable and AC-delivered capacity are shown separately.
The remaining-capacity level the cycle rating is measured to. 3,000 cycles to 80% is a stronger battery than 3,000 cycles to 70% — always read the two numbers together.

- How much does the Goal Zero Yeti 300 weigh?
- 6.2 kg (13.7 lb), manufacturer-claimed, without accessories.
- What are the dimensions of the Goal Zero Yeti 300?
- 288 × 196 × 172 mm (11.3 × 7.7 × 6.8 in), length × width × height, manufacturer-claimed.
- How much capacity does the Goal Zero Yeti 300 deliver through an AC outlet?
- About 227 Wh of the rated 296.96 Wh reaches an AC outlet from a full charge — an estimate after our published 15% inverter-loss constant (marked est. on this page).
- How many watts can the Goal Zero Yeti 300 output?
- 350 W continuous AC output and 600 W surge output, manufacturer-claimed. Appliance startup demand must stay within the relevant limit.
- How much solar input can the Goal Zero Yeti 300 accept?
