Spec deltas
Two sizes from Goal Zero's YETI lineup: Yeti 1000 (6th Gen) at 988Wh, Yeti 1500X at 1,516Wh. The $75 gap between them buys a fundamentally different tool. One you carry. One you place and leave. We'd buy the Yeti 1500X.
The Yeti 1500X holds 528Wh more than the Yeti 1000 (6th Gen) — about 9 hours on a fridge against 6 — a real but modest edge that shows up mainly on longer outages. For camping, tailgating, or keeping devices charged, both have the headroom, so price, weight, and longevity lead the decision instead.
Pick the Yeti 1500X if your primary use is remote workday or tailgate party. Go with the Yeti 1000 (6th Gen) if its specific strengths below line up better with your use. Most buyers stop at the sticker price and miss this: over a full lifespan the Yeti 1000 (6th Gen) works out to about $0.3/kWh against the Yeti 1500X's $1.48, a gap that compounds in the Yeti 1000 (6th Gen)'s favor the more you cycle it. Keep scrolling for the full breakdown. The scenario verdicts below hold a few surprises.

Weekend Camping
Two nights off-grid with essential comfort
Neither unit
Neither unit covers this scenario's 2,100Wh: the Yeti 1000 (6th Gen) comes up 1,260Wh short (about 40% covered), the Yeti 1500X 811Wh (61%). Treat this as partial cover — enough for the essentials in it, not the whole list.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
A CPAP is about 40W for eight hours, so both cover the night with room to spare and capacity decides nothing. Fan noise would — but Yeti 1000 (6th Gen) doesn't publish a figure, so there's nothing to hold it to. Buy on price, weight, and whether you can live with a fan you haven't heard.

Yeti 1500X
The Yeti 1000 (6th Gen) doesn't finish — 840Wh usable against the 910Wh this needs leaves it 70Wh short, about 93% of the scenario covered (its nameplate 988Wh actually clears this — the flat 15% conversion allowance is what tips it under). The Yeti 1500X covers it with 379Wh to spare.

Tailgate Party
Game day power for the crew
Yeti 1500X
Both handle game day; the Yeti 1500X keeps more in reserve (52% used vs 80%). Tailgating is a light load, though, so the number you'll feel is weight: 35.3 lbs for the Yeti 1000 (6th Gen) against 45.6 lbs for the Yeti 1500X, from the trunk to the setup spot.

See the full weight table and data sourcing on our methodology page →Class ranking (the star rating)
Each unit's star score is a category ranking, not customer reviews — no buyer opinions feed it. We score every station on size-independent quality (value, output, portability, endurance, ports, warranty, and more), then percentile-rank it against the other units in its capacity class, so a class-leading compact unit and a class-leading whole-home unit can both earn 5★. Here, Yeti 1000 (6th Gen) rates 4.6/5 (74th percentile of 20 Compact-class units), and Yeti 1500X rates 3.3/5 (1st percentile of 24 Everyday-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
Yeti 1000 (6th Gen): Fixed Capacity
The Yeti 1000 (6th Gen) is sealed at 988Wh — fine if that covers you, but it's the ceiling. By contrast the Yeti 1500X can add expansion batteries, so if your needs grow past 988Wh it has somewhere to go the Yeti 1000 (6th Gen) doesn't — though at this size expansion buys longer runtimes on the same loads, not a home-backup system.
Only the Yeti 1000 (6th Gen) Lists a UPS Mode
The Yeti 1000 (6th Gen) can sit between the wall and your gear and hand it to battery when the grid drops — rated ≤15ms — fine on paper for routers and most electronics; the fussiest PC power supplies sit right at this line. Worth it for a router, a desktop PC, or a CPAP. The Yeti 1500X's spec sheet lists no UPS mode, so anything plugged into it rides an outage only as far as your reaction time.
Warranty Comparison
The Yeti 1000 (6th Gen) is covered for 5 years against the Yeti 1500X's 2 years. An underrated factor if you're keeping this unit for years.
Battery Lifespan in Real Years
The Yeti 1000 (6th Gen) is rated for 4,000 cycles vs 500. In real life: at daily use, that's 11 vs 1.4 years. At weekend use (twice a week), it's 38 vs 5 years. One caution reading years across different sizes: a cycle is 988Wh on the Yeti 1000 (6th Gen) and 1,516Wh on the Yeti 1500X, so count lifetime energy — roughly 3,952 kWh against 758 kWh over the rated life. After hitting the cycle limit, the battery doesn't die — it drops to ~80% of original capacity, which is still very usable.

Analyst note
The Yeti 1000 (6th Gen) is sealed at 988Wh, which is fine if that covers you. The Yeti 1500X starts at 1,516Wh and can grow beyond it with Goal Zero expansion batteries — though at this size expansion means longer runtimes on the same loads, not a path to home backup. More hours, not more house.
The Bottom Line
The full picture comes down to this. The Yeti 1500X edges ahead on our overall analysis, but the margin is narrow enough that your specific use case should drive the decision. Review the scenario verdicts above — if the Yeti 1000 (6th Gen) wins in the scenarios that match your life, it's the right choice regardless of aggregate scores.
If neither the Yeti 1000 (6th Gen) nor the Yeti 1500X feels like the right fit, your power needs probably sit outside what these two target. Use our comparison tool above to explore alternatives that better match your specific wattage and runtime requirements. Prices on portable power stations fluctuate frequently. Both Goal Zero discount regularly, so check the current price before committing. Prime Day and Black Friday pricing typically drops 20-30%.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
How does the 528Wh capacity difference actually affect daily use?
The Yeti 1500X's 1,516Wh battery keeps a mini-fridge running for roughly 9 hours vs the Yeti 1000 (6th Gen)'s 6 hours. What specs don't mention: runtime drops 20-30% in cold weather (below 32°F/0°C) as battery chemistry slows down. The Yeti 1500X's extra capacity provides a critical cold-weather buffer. For occasional phone and laptop charging, both are overkill. This gap only matters for sustained, multi-appliance use.
Can I actually carry the Yeti 1500X, or is the Yeti 1000 (6th Gen) the only portable option?
Neither is "portable" in any hiking sense. The Yeti 1000 (6th Gen) (35.3 lbs) and the Yeti 1500X (45.6 lbs) are both appliances you place and leave. The 10.3-lb difference matters when loading into a vehicle or moving between rooms, but that's about it. If true portability is your priority, look at units under 20 lbs in a different class entirely.
How fast can each unit recharge from solar panels in real conditions?
On paper, the Yeti 1000 (6th Gen) accepts 900W vs the Yeti 1500X's 600W of solar input. What the spec sheet won't tell you: solar panels typically deliver only 60-80% of their rated output due to panel angle, cloud cover, and temperature. In realistic conditions, expect full recharge in about 1.6 hours for the Yeti 1000 (6th Gen) and 3.6 hours for the Yeti 1500X. That gap widens on cloudy days, when the Yeti 1000 (6th Gen)'s higher input ceiling captures more of whatever sunlight is available. One more thing: summer gives you ~7 productive solar hours per day. Winter drops to ~4. If solar is your primary recharge method, the Yeti 1000 (6th Gen)'s advantage is substantial.
"4,000 vs 500 cycles" — what does that actually mean for me?
In real years: the Yeti 1000 (6th Gen) (4,000 cycles) lasts 11.0 years at daily use, 38 years at weekend use (twice a week), or 167 years at twice-monthly camping trips. The Yeti 1500X (500 cycles): 1.4 years daily, 5 years weekends, or 21 years twice-monthly. What most people miss: hitting the cycle limit doesn't kill your battery. Capacity drops to about 80%. Your 988Wh unit becomes a ~790Wh unit. Still very usable. For weekend users, both batteries will outlast the warranty by years.
Can I use the Yeti 1000 (6th Gen) as a home UPS to protect my electronics during blackouts?
Yes. The Yeti 1000 (6th Gen) has UPS mode that keeps your devices running through power transitions. Plug in your desktop PC, router, NAS, or CPAP machine and it switches to battery seamlessly when the grid drops. The Yeti 1500X does not have this feature. Without UPS, a blackout means: your PC reboots (potentially corrupting unsaved work), your NAS may corrupt its drive array, your CPAP alarms and wakes you up, and your security cameras go dark until you manually switch them over. If always-on power protection matters, this is a dealbreaker advantage for the Yeti 1000 (6th Gen).
What if I need more capacity than the Yeti 1000 (6th Gen)'s 988Wh later?
The Yeti 1000 (6th Gen) is sealed at 988Wh, so if you expect your needs to climb, the Yeti 1500X is the more future-proof pick: it starts at 1,516Wh and adds Goal Zero-compatible batteries without replacing the base unit. That said, "not expandable" isn't a flaw on its own — if 988Wh comfortably covers your loads, the Yeti 1000 (6th Gen) is a complete unit, not a downgrade.
Bottom line: should I buy the Yeti 1000 (6th Gen) or the Yeti 1500X?
We'd buy the Yeti 1500X. Cheaper and more capable. That combination is rare. The Yeti 1000 (6th Gen) doesn't offer a compelling reason to spend more unless you specifically need a feature unique to the Goal Zero ecosystem (expansion batteries, app integrations). Otherwise, clear call.
