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 17.8 nights | 9 W · |
| CPAP (heated humidifier on) | about 2.9 nights | 56 W · |
| Refrigerator (full-size) | about 20 hours | 180 W × 35% duty cycle · |
| Wi-Fi router + modem | about 71 hours | 18 W · |
| Laptop (65W charger) | about 39 hours | 65 W × 50% duty cycle · |
| Phone (one full charge) | about 63 full charges | 20 W · |
Who it fits
Mechanical matches against this model's own sourced specs — never invented sentiment, never a guess on a spec we don't have.
1279 Wh AC-delivered (est.) → multiple CPAP nights per charge
2000 W inverter, 1279 Wh AC-delivered (est.) → runs a fridge through an outage

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.

Energy available from the battery before output-conversion losses. AC-delivered capacity is shown separately in Capacity Truth.
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.

What reviewers & owners report
Named outlets and marketplaces, each rating credited where it was published.
Brand reputation: Heritage US brand (Bluffdale UT). New 6th-gen switched to LiFePO4 (older Yeti X line was NMC). BBB A+ (not accredited) - best-rated of the majors; Trustpilot 4.2 but thin (76). Premium price vs LFP rivals is the recurring critique.
