Goal Zero Yeti 1000X vs Goal Zero Yeti 1500X
Goal Zero Yeti 1000X vs Goal Zero Yeti 1500X: buy the Yeti 1000X only if your heaviest day fits inside its roughly 836Wh of usable energy, because the 1500X is no longer sold, and if you need more, look at its successor, the Yeti 1500 (6th Gen).

Spec deltas
Goal Zero no longer sells the Yeti 1500X. Its replacement is the Yeti 1500 (6th Gen), which moves to LiFePO4 cells, a chemistry rated for far more charge cycles. That leaves the Yeti 1000X at $1,000 as the only one of these two still in the range. Even that one read sold out at Goal Zero's store in early November, with a button to be told when it returns.
I have history with this family. My first battery was a lead-acid Goal Zero Yeti 400 that lost half its capacity on cold Tahoe mornings. Both of these sit a generation on from that, on NMC lithium cells rated for 500 cyclesA1B1. A cycle is one full drain and refill. Reviewers say the 1000X kept working in both cold and heatA2, which is the first thing I'd want to know about any box headed for my deck.
What's left to decide is whether 983Wh of older chemistry covers your heaviest day. If it does, and you can find one, the 1000X is the lighter box. If it doesn't, the 6th Gen is the next place to look.
What the Numbers Reveal
Each conclusion stated first β the numbers behind it on one line, the full analysis below.
Trim the day by a tenth, with a monitor off early or a laptop asleep over lunch, and the gap closes. The 1500X finished the same day with 379Wh to spare.
Remote Workday needs 910WhThe 1000X has about 836Wh usable after the flat 15% conversion allowanceThe 1500X had about 1,289Wh usable on the same basis
Why it mattersFor a full workday on the 1000X, plan to trim the load or top up at lunch.
The weak point is the cycle rating. On our lifetime model, daily use takes the pack to 80% of its capacity in under a year and a half. At a weekend pace the same 500 cycles last close to five years.
Both cap solar input at 600WBoth are rated for 500 cycles to 80% on NMC cellsA1B1
Why it mattersWeekend use suits this chemistry. Daily off-grid use calls for LiFePO4.
The specific dimensions that decide these two units β everything else is a tie.
Lifetime Value
Selected because: With the 1500X retired, only the 1000X has a price, and its 500-cycle rating shapes what that price buys.
For a new buy, the figure that matters is the 1000X's own: $2.03 per kilowatt-hour over its rated life. A short rated life gives the price little to spread across. The warranty is two years on both.
If I bought a 1000X, I'd treat it as a weekend battery.
Your Life, Your Pick
Selected because: Remote Workday is the near miss that separated the two, and three profiles are out of reach for both.
Three of the six load profiles are out of reach for both. A camping weekend, an eight-hour blackout and a van-life day all need more than either box holds.
The light jobs are where the 1000X lives. A CPAP night uses well under half of it. A tailgate afternoon leaves it 166Wh in hand.
Portability & Form Factor
Selected because: About 14 lbs separates them, in the 1000X's favor.
weight
Neither is a one-hand grab. At 31.68 lbs the 1000X is a heavy bag. At 45.64 lbs the 1500X is a box you squat for. For a new buyer, that's a point for the 1000X.
PowerScore Breakdown
Selected because: The 1500X ran 500W more continuous, which matters to current owners.
overall power score
The 1500X ran 2,000W continuous with a 3,500W surge. The 1000X runs 1,500W with a 3,000W surge. Surge is the brief spike a motor pulls as it starts. Both ceilings clear a typical fridge compressor.
For a new buyer, 1,500W continuous covers most single appliances you'd plug in at a campsite. Two big heating loads at once can exceed it.

Neither unit
Neither unit covers this scenario's 2,100Wh: the Yeti 1000X comes up 1,264Wh short (about 40% covered), the Yeti 1500X 811Wh (61%). Treat this as partial cover β enough for the essentials in it, not the whole list.

CPAP Overnight
Sleep therapy without interruption β the #1 medical use case
Either unit
A CPAP is about 40W for eight hours, so both of these cover the night at least twice over β capacity isn't the question here. What would separate them is fan noise, but neither maker publishes a fan-noise figure, so there's nothing to hold either of them to. Only the Yeti 1000X is still sold, so for a new buy it takes this by default; the Yeti 1500X is worth weighing on weight and fan noise only if you already own one.

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: 31.7 lbs for the Yeti 1000X against 45.6 lbs for the Yeti 1500X, from the trunk to the setup spot.

Conclusion
October 25, 2026
Verdict: the Goal Zero Yeti 1000X
Take the Yeti 1000X if one of these two is the one you want. Goal Zero has retired the 1500X, so the 1000X is the only live unit here, though Goal Zero's store showed it sold out when we checked in early November. The 1500X was the stronger machine, at 1,516Wh to 983Wh and 2,000W continuous to 1,500W. Both run older NMC cells rated for 500 cycles, so the 1000X suits tailgate-sized and CPAP-sized jobs. If you wanted the 1500X for its headroom, compare its replacement, the Yeti 1500 (6th Gen) on LiFePO4 cells.

Each unit's star score is a category ranking, not customer reviews β 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 5β . Here, Yeti 1000X rates 3.5/5 (11th percentile of 20 Compact-class units), and Yeti 1500X rates 3.3/5 (1st percentile of 27 Everyday-class units).

Analyst note
The Yeti 1500X is no longer sold, so there is no price to work its cost per kWh from, and this comparison doesn't quote one. On what you can actually buy today, the Yeti 1000X works out at $2.03/kWh over its rated life. If you already own the Yeti 1500X, the hardware comparison still holds: over its rated life the Yeti 1000X delivers about 492 kWh and the Yeti 1500X about 758 kWh. One thing to know reading the table: both carry the same 500-cycle rating, so the lifetime rows are sticker price and capacity in disguise β the wear horizon is identical and decides nothing here.

Analyst note
Growth only counts if you can still buy in, and the Yeti 1500X is no longer sold (Goal Zero points owners to the Yeti 1500 (6th Gen)). That leaves the Yeti 1000X: it starts at 983Wh and takes Goal Zero expansion batteries, so the ceiling moves if your needs do. The Yeti 1500X's expandability still matters if you already own one, but it isn't a reason to pick it over the Yeti 1000X.
What Owners Report
Patterns from published owner reports and long-term reviews β every claim cited to its source below.
Goal Zero Yeti 1000X
The most repeated criticism of the 1000X is its chemistry. It uses NMC cells rated for 500 cycles to 80%, while current LiFePO4 rivals are rated for 3,000+A1. Reviewers also call it pricey for its capacity, with those rivals charging faster and lasting longerA4.
The praise is about build and behavior. Reviewers describe a premium unit that ran a mini fridge for 12 hours and worked in both cold and hot conditionsA2. It also expands through Goal Zero's Yeti Link system, which needs extra cables and adaptersA3.

Who Should Buy Which
Buy the Yeti 1000X if youβ¦
- βYour heaviest regular job is a tailgate afternoon or a CPAP night. The 1000X covers both with room left.
- βYou carry it alone. At 31.68 lbs it's the lighter of the two by about 14 lbs.
- βYou use it on weekends rather than every day, which suits a pack rated for 500 cycles.
Buy the Yeti 1500X if youβ¦
- βYou already own a 1500X. It still does what it did, including a full remote workday with margin and 2,000W continuous.
- βYou want this size class new. Goal Zero's replacement is the Yeti 1500 (6th Gen) on LiFePO4 cells.
If neither fits
If the job is a two-night camping trip, an eight-hour multi-appliance blackout or a van-life day, neither box gets there alone. Those profiles need 1,645Wh and up. Look at a larger station, ideally on LiFePO4 cells.
The Bottom Line
The 1500X was the stronger unit, and it's gone. That leaves the Yeti 1000X, if you can find one, since Goal Zero's store last showed it sold out. It's well built, and it handles a CPAP night or a tailgate with room left.
Its limits are the ones reviewers keep naming: older NMC cells rated for 500 cycles and a high price for its sizeA1A4. Buy it for light, occasional use. If you wanted the 1500X for its headroom, the Yeti 1500 (6th Gen) is where that search goes now.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
What's actually different between the Goal Zero Yeti 1000X and Yeti 1500X?
Capacity, output and weight. The 1000X holds 983Wh, outputs 1,500W continuous and weighs 31.68 lbs. The 1500X holds 1,516Wh, outputs 2,000W continuous and weighs 45.64 lbs. Chemistry, cycle life, warranty and solar input are identical. Goal Zero no longer sells the 1500X.
Can I still buy the Yeti 1500X?
Not from Goal Zero. It has left the range, and Goal Zero points buyers to the Yeti 1500 (6th Gen), which uses LiFePO4 cells rated for far more cycles. The Yeti 1000X is still in the range, but Goal Zero's store showed it sold out when we checked in early November.
Which one is cheaper to own over its lifetime?
For a new buy, only the 1000X has a price. Our lifetime model puts it at $2.03 per kilowatt-hour delivered over its 500 rated cycles. Both carry the same two-year warranty.
Can either the 1000X or 1500X run a full workday of laptop, monitor, and router?
Only the 1500X, on our model. That load needs about 910Wh. The 1000X has about 836Wh usable after a flat 15% conversion allowance, so it comes up 74Wh short, though its nameplate 983Wh would clear it. Trimming the load slightly would close the gap. The 1500X covers it with room to spare.
Do both units support solar or battery expansion?
Both accept the same 600W solar input and both expand through Goal Zero's Yeti Link system, which needs separate cables and adapters. For a new buyer, only the 1000X's growth path is open, since the 1500X is no longer sold.
