Anker SOLIX C1000 Gen 2 vs Goal Zero Yeti 1000X
The C1000 Gen 2 is $470 cheaper and rated for 4,000 charge cycles against the Yeti 1000X's 500, so Goal Zero has to win this on something other than being a battery.

Spec deltas
Take the Anker SOLIX C1000 Gen 2. It's $530 against the Yeti 1000X's $1,000, and the cheaper box is also the one with more capacity, more continuous output, more warranty and less weight. Pages like this are usually about what you trade away to save money. This one isn't.
Chemistry is what splits them. The Yeti 1000X uses lithium NMC cells rated for 500 cycles to 80%B1, which reads badly in a market where its rivals ship LiFePO4 good for 3,000-plusB1B4. The Anker is rated for 4,000. Run each one down and back every day and the Anker's rating covers about 11 years while the Yeti's is spent in about 1.4.
Goal Zero's advantages are worth naming out loud: a weather-resistant IPX4 build, the Yeti-Ready ecosystem of coolers, panels and vehicle kits that nothing Anker makes plugs into, and an inverter that carries twice its continuous rating on surge. Those are the reasons someone already inside that ecosystem still buys one. They aren't reasons to spend $470 more on a battery rated to wear out eight times sooner.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
rated cycles
Divide each price by the energy it's rated to deliver and the Yeti lands at $2.03 per lifetime kilowatt-hour against the Anker's $0.13. Read that once and everything after it is bookkeeping: you'd be paying nearly twice the money for an eighth of the energy, and no port layout, app or badge closes a gap that size.
Yeti 1000X: 983Wh rated for 500 cycles, priced at $1,000SOLIX C1000 Gen 2: 1,024Wh rated for 4,000 cycles, priced at $530Rated lifetime energy works out to 492 kWh for the Yeti and 4,096 kWh for the Anker
Why it mattersAnyone who plans to actually cycle the thing, whether that's weekly camping, seasonal outages or van power, can stop reading here and buy the Anker.
continuous output
Ten milliseconds is UPS-grade: a desktop, a modem or a NAS rides through the handoff without noticing. The Yeti 1000X has no UPS mode, so nothing is specified about what a connected load does at the moment of the cut. You'd be relying on hope rather than a number. Add the Anker's extra 500W of continuous headroom and the cheaper box is also the one you'd wire a home office into.
SOLIX C1000 Gen 2 switches to battery in 10 msYeti 1000X has no UPS modeContinuous output is 2,000W on the Anker and 1,500W on the Yeti; both peak at 3,000W surge
Why it mattersIf what you're protecting is a computer with unsaved work or a rack that hates rebooting, this settles it on its own.
Capacity
Energy density normally costs money, so the light one is usually the expensive one. Not here. The Yeti's extra weight does buy a weather-resistant IPX4 shell, and that's worth real money if the unit lives in an open truck bed. It doesn't buy watt-hours, and it doesn't buy USB-C either.
SOLIX C1000 Gen 2: 1,024Wh at 24.9 lbYeti 1000X: 983Wh at 31.68 lbThe Anker costs $470 less and pushes 140W out of USB-C to the Yeti's 60W
Why it mattersAnyone hauling this into a truck bed, a rooftop tent or down basement stairs takes the Anker and keeps the difference.
Anker's 35 dB is a low-load figure, and reviewers confirm it holds there, with the fans only climbing to around 55 dB during fast charging or above 1,000WA2. Neither of those describes a CPAP night. Goal Zero publishes nothing, so there's no figure to compare and nothing to hold them to after the box arrives.
A CPAP night draws 320Wh, which is 37% of the Anker's usable capacity and 38% of the Yeti'sAnker publishes 35 dB for the C1000 Gen 2Goal Zero publishes no noise figure for the Yeti 1000X
Why it mattersThe person buying this for a CPAP or a bedroom should take the unit that told them the number.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: The Anker costs $470 less up front and is rated for eight times the total energy, which is where this comparison gets decided.
cost / lifetime kWh
Spread each price across the years its maker will stand behind it and the Anker works out to $110 per warranty year. The Yeti works out to $500. That's before a single kilowatt-hour has moved.
Weekend use is where it stops being abstract. Cycle each unit on Saturdays and Sundays and the Anker's rating covers 38.5 years, which is longer than you'll want to own anything with a battery in it. The Yeti covers 4.8. Five camping seasons, then you're shopping again.
What the Specs Don't Tell You
Selected because: Only one of these has a UPS mode, only one publishes a noise figure, and the warranties run 5 years against 2.
rated cycles
Four of the five cards below point at the Anker, so start with the one that doesn't. The Yeti's inverter carries 3,000W of surge on a 1,500W continuous rating, twice what it's rated for, while the Anker reaches the same 3,000W ceiling from 2,000W continuous. Doubling is the mark of an inverter built with margin, and it's a genuine point for Goal Zero.
The other four have consequences. Only the C1000 Gen 2 has a UPS mode. Only Anker publishes a noise figure, which means the Yeti's fan behavior is something you discover after delivery. And the warranty runs 5 years against 2, a short leash on the component most likely to age out first.
Your Life, Your Pick
Selected because: Both are roughly 1kWh boxes, so the real question is which jobs they finish and which ones they don't.
A kilowatt-hour is a specific amount of life: a CPAP night with two-thirds left over, a tailgate, a long evening of laptops and lamps. It is not a weekend of camping at 2,100Wh, and it is not an 8-hour blackout at 1,645Wh. Choosing between these two doesn't change that, and solar input is a dead heat at 600W each, so whatever panel you buy helps both equally.
The near miss is the one to watch. A remote workday asks 910Wh, which lands at 105% of the Anker's usable capacity and 109% of the Yeti's. Both come up short by a rounding error. If your day looks like that, the answer isn't the other box on this page, it's a panel on the roof or a lunchtime top-up.
Brand Trust
Selected because: Goal Zero's premium has always been underwritten by heritage and support, and support is the half that has slipped.
Goal Zero's price has always been underwritten by two things: it invented this category, and its support used to beat everyone's. The first is still true. The second has slipped, with long queue times, tickets sitting for weeks, and the official community forums closed, which is a strange thing to do to the customers most likely to defend you.
Anker isn't a clean story either, and you should know that going in. SOLIX support has drifted toward canned AI responses, returns on heavy units mean hazmat shipping, and firmware updates have pulled features without notice. What differs is the price of the risk. Both brands have come down from their peak. Only one of them is charging premium money on the strength of it.
Portability & Form Factor
Selected because: The cheaper unit is also the lighter one, 24.9 lb against 31.68 lb, which is not how this usually goes.
weight
Six and three-quarter pounds separates these, and it falls right on the line where a carry stops being casual. Under 25 pounds you grab the handle and go. Past 30 you think about it first, and you think about it every single time.
The Anker also throws 140W out of USB-C against the Yeti's 60W, which for a lot of buyers is one fewer brick in the bag. Reviewers already flag the Yeti's port selection as thin for the moneyB4. That's the kind of thing you never notice in a spec table and notice constantly at a campsite.

Scenario math and per-appliance runtimes, modeled from the spec record.
Scenario verdicts
We ran the math on six real-world scenarios. Here's which unit survives your actual life.
SCN-01 · 2 nights · needs 2,100Wh
Weekend Camping
Two nights off-grid with essential comfort
Neither unit
A weekend off-grid runs about 2,100Wh, which is 241% of what the Anker can actually deliver and 251% of the Yeti's. Neither finishes the trip on a single charge, and the small capacity difference between them doesn't change that answer. Both will start everything you'd plug in, so the fix isn't the other box on this page. It's a panel, a car charger, or a bigger unit.

SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
Neither unit
Eight hours of fridge, lights, router and phones adds up to about 1,645Wh. These hold 1,024Wh and 983Wh. Both can start every load on that list; neither can finish the night. Buy either one expecting to cover most of a blackout rather than all of it, and keep a way to put energy back in during daylight.
Battery budget usedlower = more headroom
LOAD Fridge 150W×8h · Router + Modem 20W×8h · LED Lights (4 bulbs) 40W×6h · Phone Charger 15W×3h
SCN-03 · 8 hours · needs 320Wh
CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
A CPAP asks about 320Wh and leaves roughly two-thirds of either unit untouched, so capacity isn't what you're choosing on. The box two feet from your pillow is. Anker publishes 35 dB for the C1000 Gen 2 and gives it a 10 ms UPS switchover, so a grid blip hands over without the machine noticing. Goal Zero publishes no noise figure for the Yeti 1000X and gives it no UPS mode. That's the tiebreak on an otherwise even night.
Battery budget usedlower = more headroom
LOAD CPAP Machine 40W×8h
SCN-04 · 8 hours · needs 910Wh
Remote Workday
Full work day off-grid without power anxiety
Neither unit
This scenario needs 910Wh and neither unit quite finishes it. The SOLIX C1000 Gen 2 lands within 5% of it — close enough that trimming one appliance, or accepting a shorter evening, gets you there on the day.
Battery budget usedlower = more headroom

Tailgate Party
Game day power for the crew
Either unit
Both handle game day easily. Since capacity isn't the deciding factor, weight is: at 24.9 lbs the SOLIX C1000 Gen 2 is the one you'll be glad you brought. Fan noise under load is worth a listen too — it's audible in the lulls between songs.

Van Life Daily
A full day of mobile living — the ultimate endurance test
Neither unit
Neither unit covers this scenario's 4,685Wh: the SOLIX C1000 Gen 2 comes up 3,815Wh short (about 19% covered), the Yeti 1000X 3,849Wh (18%). This is well outside what either unit is for; the right answer here is a larger station, not a choice between these two.

Conclusion
August 4, 2026
Verdict: the SOLIX C1000 Gen 2
Buy the Anker SOLIX C1000 Gen 2. It costs $530 to the Yeti 1000X's $1,000, holds 1,024Wh against 983Wh, runs 2,000W continuous against 1,500W, weighs 24.9 lb against 31.68 lb, carries a 5-year warranty against 2, and is the only one of the two with a UPS mode. Goal Zero's case rests on a weather-resistant IPX4 build, the Yeti-Ready ecosystem of coolers, panels and vehicle kits, and an inverter that doubles its continuous rating on surge. All three are real. None of them survives 500 rated cycles against 4,000. The one honest reason to take the Yeti is that you already own Goal Zero panels, Link hardware or Yeti-Ready gear and you cycle the thing a few times a year.

Power Score
Computed from 14 published spec dimensions, weighted per use-case bench. Higher is better; a unit must meet a bench's minimum threshold to be rated.
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, SOLIX C1000 Gen 2 rates 4.9/5 (96th percentile of 27 Everyday-class units), and Yeti 1000X rates 3.5/5 (11th percentile of 20 Compact-class units).
How the class ranking is computed →Test Notes & Caveats
Hidden gotchas and advantages we spotted that you won't find on the product page.
The one card that goes Goal Zero's way
Both units peak at 3,000W, but they arrive there from different places. The Yeti holds 1,500W continuous and doubles it on surge; the Anker holds 2,000W and adds half again. Twice the rated output is the signature of an inverter built with real margin, and it's a legitimate point in the Yeti's favor. It doesn't change what either one can start, since the ceiling is the same 3,000W, and the Anker is the one that can hold 2,000W all afternoon.
Ten milliseconds, or no promise
Only the SOLIX C1000 Gen 2 has a UPS mode. Plug a desktop, a modem or a NAS into it and when the grid drops the handoff takes 10 milliseconds, fast enough that the machine keeps running. The Yeti 1000X has no UPS mode, so nothing is specified about what a connected load does at the instant power cuts. If the thing you're protecting is a computer with unsaved work, this card is the whole decision.
Warranty: 5 Years vs 2
The SOLIX C1000 Gen 2 is covered for 5 years against the Yeti 1000X's 2 years. An underrated factor if you're keeping this unit for years.
Two units, two very different clocks
4,000 rated cycles against 500. Charge and drain each one daily and the Anker's rating covers about 11 years while the Yeti's is used up in about 1.4. Weekends only stretches that to 38.5 years against 4.8. A 500-cycle rating doesn't mean the Yeti stops dead, it means that's where it's down to 80% of the capacity you paid for. You'll be shopping again while the Anker is barely broken in.
Yeti 1000X: Noise Level Not Disclosed
The SOLIX C1000 Gen 2 publishes its noise level (35dB); the Yeti 1000X doesn't publish one. That isn't evidence the Yeti 1000X is louder — it means there's no figure to hold it to, and no way to compare the two on this without hearing them. If you're buying for a bedroom, a CPAP, or an apartment, treat the SOLIX C1000 Gen 2's 35dB as the only published number on the table — a spec-sheet figure, not a measurement — and look for hands-on reports of the Yeti 1000X before deciding.

Ecosystem
7-8 SOLIX portable power stations across C-series (compact) and F-series (flagship), plus the X1 home energy system
Support
US-based support. Historically known for incredible no-hassle replacements, but recent reports describe AI-driven support agents giving generic responses and complex return logistics for heavy units (hazmat shipping). The Anker brand reputation is still strong, but SOLIX-specific support quality is trending down.
Community
Moderate — active Reddit (r/Anker, r/AnkerSOLIXCommunity) and growing. Benefits from Anker's massive consumer electronics brand awareness.
App experience
Rated 4.5/5 iOS (~1,100 ratings) · 4.3/5 Android
Unique strength
Parent brand trust from Anker's consumer electronics dominance. InfiniPower technology for long cycle life. Strong $/Wh value in the mid-size and larger units — the S2000, F2600 and C1000 are among the better buys per watt-hour in the catalog.
Worth knowing
Support quality appears to be declining from its historically excellent level. Firmware updates have removed features without warning. Expansion ecosystem is smaller than EcoFlow's.
Goal Zero
Ecosystem
Focused — a compact current line (6th-gen Yeti and Yeti Pro series), the previous-gen X series now out of stock across every model on Goal Zero's own store (checked 2026-09-13: 200X, 500X, 1000X, 1500X, 3000X, 6000X, some listed only as open-box), so buying one new means finding retailer stock, Sherpa power banks for the under-100Wh tier, plus Alta coolers, Nomad/Ranger solar panels, and vehicle integration kits
Support
US-based company (Salt Lake City, owned by NRG Energy). Historically considered premium support, but 2025-2026 reports describe long wait times, unresponsive email communication, and tickets going unaddressed for weeks. The "premium support justifies premium pricing" argument is weakening.
Community
Small but loyal — strong following in overlanding and preparedness communities. Official community forums were recently shuttered, frustrating long-time users.
App experience
Rated 4.4/5 iOS (~1,200 ratings) but recent reviews skew negative — recurring connectivity issues, crashes, and stability problems.
Unique strength
Pioneer of the portable power market — strongest brand heritage. US-based company with ruggedized, weather-resistant designs (IP ratings vary by model). Integrated "Yeti-Ready" ecosystem with coolers, lights, and vehicle kits.
Worth knowing
Typically the priciest brand per watt-hour — though individual pairings vary, and on some pages the Yeti is the cheaper energy. Support quality has declined from its "premium" standard. Perceived as competitively stagnant vs. faster-innovating Chinese competitors. Reliability reports on newer models are concerning.
Analyst note
Both of these brands currently have better support reputations than support. Anker's SOLIX line has drifted toward scripted responses and hazmat return logistics on heavy units; Goal Zero's queue times have stretched, tickets sit for weeks, and it shut the official community forums that its most loyal customers lived in. The difference is what you're paying for that risk. The Anker is value-priced with average support exposure. The Yeti is premium-priced on the strength of a support story the brand no longer delivers.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
Anker SOLIX C1000 Gen 2
Reviewers land on the same two strengthsA1A3. It refills startlingly fast, a full charge in roughly 49 minutes against the original C1000's 58 to 80A1, and the higher continuous output crosses a threshold that matters in practice, enough to run a 1,500W space heater with room to spareA3. The consensus read is that it's the mid-size unit to beat in 2026A4.
The recurring complaint is noise. It's close to silent under about 200W, around 35 dB, but the fans ramp audibly during fast charging or heavy draw, reaching roughly 55 dB past 1,000WA2. If you plan to use that 49-minute charge often, plan on hearing it.

The build earns genuine praise. Reviewers describe premium construction at about 31.68 lb and reliable field behavior, including a 12-hour run on a mini fridge and no trouble in either cold or heatB2. Nobody accuses this unit of feeling cheap.
The complaints are all about chemistry and value, and they're consistent: 500 cycles to 80% from NMC cells in a market where rivals reach 3,000-plusB1, about $1.02 per watt-hour when LFP competitors offer more capacity for less and charge fasterB4, and a Yeti Link expansion path that works but wants extra cables and adapters firstB3. The unit is well made. The argument is over what it costs to own.

Who Should Buy Which
Buy the SOLIX C1000 Gen 2 if you…
- →The home office that can't reboot: a desktop, a modem and a NAS behind a 10 ms switchover, with 2,000W continuous so the space heater under the desk doesn't trip anything.
- →Anyone cycling it weekly or more. At 4,000 rated cycles, weekend use runs 38.5 years on paper, so you'll replace it because something better exists, not because it died.
- →The person doing the lifting. 1,024Wh at 24.9 lb is 41 watt-hours per pound, the best on this page by a wide margin, and it's the cheaper box.
- →CPAP and bedroom duty, where 320Wh a night leaves roughly two-thirds in the tank and the published 35 dB low-load figure is the spec that actually decides your sleep.
Buy the Yeti 1000X if you…
- →You already own Goal Zero gear. Nomad or Ranger panels, Yeti Link hardware, Yeti-Ready coolers and vehicle kits are a real ecosystem, and nothing Anker sells joins it.
- →The unit lives outdoors. IPX4 weather resistance and a build reviewers call premiumB2 is worth paying for when the box rides in an open truck bed instead of a closet.
- →You'll cycle it a handful of times a year. At that rate 500 cycles is a long horizon, and the chemistry argument mostly stops applying to you.
If neither fits
If what you actually need is an 8-hour blackout with the fridge running (1,645Wh) or a weekend off-grid (2,100Wh), neither of these finishes the job on one charge, and buying the more expensive one doesn't help. Shop the class above these, or budget for a solar panel from day one. Van-lifers pulling 4,685Wh a day are looking at four to five times what either box holds (1,024Wh and 983Wh), which is a different product category, not a closer call.
The Bottom Line
Buy the Anker SOLIX C1000 Gen 2. It's $470 cheaper, holds more energy, pushes more continuous power, weighs nearly seven pounds less, and is rated for 4,000 cycles against 500, which is why one of these costs pennies per lifetime kilowatt-hour and the other costs dollars.
The Yeti 1000X is genuinely well built, and there's a real buyer for it: someone already inside the Yeti-Ready ecosystem who leaves the box outdoors and cycles it a few times a year. If that isn't you, you're paying $470 for a shell and a badge. Take the Anker and put some of what you saved toward a solar panel, because neither of these covers a full blackout without one.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the Goal Zero Yeti 1000X worth twice the price of the Anker SOLIX C1000 Gen 2?
Not on the numbers. The Yeti costs $1,000 to the Anker's $530 while holding less energy (983Wh against 1,024Wh), pushing less continuous power (1,500W against 2,000W), and carrying a 2-year warranty against 5. What the premium buys is a weather-resistant IPX4 build and the Yeti-Ready ecosystem of coolers, panels and vehicle kits. Unless you already own that gear, it doesn't return anything.
Can the Yeti 1000X be used as a UPS for a computer?
No. It has no UPS mode, so there's no specified switchover behavior when grid power cuts. The Anker SOLIX C1000 Gen 2 does have one, at 10 milliseconds, which is fast enough that a desktop keeps running through the handoff. If backing up a computer is why you're shopping, that's a hard difference rather than a preference.
How long will each of these last before the battery wears out?
The Yeti 1000X is rated for 500 cycles to 80% capacity; the C1000 Gen 2 is rated for 4,000. Cycled daily, that's about 1.4 years against 11. Cycled on weekends only, 4.8 years against 38.5. Neither is scrap at its rating, since that's the point where capacity has fallen to 80% of what you bought, but the two are running on completely different clocks.
Will either one run a refrigerator through an 8-hour power outage?
Both will start a fridge, since each has 3,000W of surge headroom. Neither carries a typical 8-hour outage load of 1,645Wh on a single charge, because they hold 1,024Wh and 983Wh. Expect to cover most of the outage, not all of it. If you want the whole night without recharging, you need something closer to double these capacities.
Which one is quieter?
Only one of them can be checked. Anker publishes 35 dB for the C1000 Gen 2 and Goal Zero publishes no noise figure at all for the Yeti 1000X. Reviewers describe the Anker as close to silent at low draw, with the fans getting audibly louder during fast charging or above 1,000W, around 55 dB. For a CPAP or a bedroom, that low-load figure is the one that matters, and it's a good one.
