Anker SOLIX F2000 vs Goal Zero Yeti PRO 4000
The real question isn't which battery is better but whether you need 4,000Wh fixed in one place badly enough to pay roughly four times the price and give up a unit one person can actually move.

Spec deltas
The Yeti PRO 4000 costs $4,000 and weighs 115.7 lbs. The SOLIX F2000 costs $900 and rolls out on its own wheelsA1. Nearly double the capacity sits on the Yeti's side of the table, and almost none of it matters unless you need that energy fixed in one place badly enough to pay for it.
The price tag hides the worse part for the Yeti: its energy costs more per kilowatt-hour over the full life, not less. Fifteen cents a lifetime kilowatt-hour for the SOLIX, twenty-five for the Yeti. It does deliver more total energy, 15,976 kWh across its rated cycles against the SOLIX's 6,144, but every one of those kilowatt-hours costs you more than the cheaper unit's do.
So this goes to the SOLIX for most people, and on value it isn't close. The Yeti earns its price in one situation: a fixed install, home backup or an off-grid cabin, where you need close to 4,000Wh on tap and the surge headroom to start a fridge, an AC compressor, and a power tool at once without tripping. If that's not the box you're shopping for, the wheeled $900 unit does the job and leaves the other $3,100 in your account.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
cost / lifetime kWh
The Yeti's biggest number, total energy delivered, is exactly where it loses on value: the bigger battery stores the more expensive kilowatt-hour, so you're not buying cheaper power, you're paying to keep all of it in one 116-lb box.
Yeti lifetime energy 15,976 kWh (3,994Wh x 4,000 cycles); SOLIX 6,144 kWh (2,048Wh x 3,000 cycles)Prices: SOLIX $900, Yeti $4,000Cost per lifetime kilowatt-hour: SOLIX $0.15, Yeti $0.25
Why it mattersIf the goal is the lowest cost per kilowatt-hour, the SOLIX wins outright; the Yeti is worth its price only when the energy genuinely has to be concentrated in one fixed unit.
weight
For any use where the unit itself has to go somewhere, campsite, tailgate, a friend's place, the SOLIX's smaller battery is the one that shows up, and the Yeti's capacity edge exists only where the Yeti can sit.
SOLIX F2000: 67.2 lbs on 4.72-inch wheels with a retractable handle; Yeti PRO 4000: 115.7 lbs, listed as stationaryUsable energy: SOLIX 1,741Wh, Yeti 3,395WhTailgate load of 670Wh: SOLIX covers it with 1,071Wh to spare; the Yeti can't get there
Why it mattersIf you relocate your power station even a few times a year, treat the Yeti's extra 1,654Wh as unavailable, not merely heavier.
continuous output
Stack a full-size fridge, an AC compressor, and a power tool starting together and the SOLIX is the one likely to trip while the Yeti absorbs the spike, and that, not raw capacity, is the Yeti's most defensible reason to cost what it does.
Yeti surge 7,200W (2x its 3,600W continuous rating); SOLIX surge 2,800W (1.2x its 2,400W rating)Fridge, AC, and power-tool motors briefly pull 2-3x their running draw at startup
Why it mattersBuyers with heavy simultaneous motor loads, a well pump, a big fridge plus AC, shop tools, are the ones who should actually pay up for the Yeti.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: The price gap dwarfs everything else: $900 against $4,000, and the SOLIX is also the cheaper energy at $0.15 per lifetime kilowatt-hour versus $0.25.
cost / lifetime kWh
Nine hundred dollars buys the SOLIX; four thousand buys the Yeti. The gap between them would buy three more SOLIX units and leave change, and it doesn't come back to you as cheaper energy, since the bigger battery stores the pricier kilowatt-hour rather than the other way round. Warranty doesn't rescue the Yeti either: both carry five years, which pencils out to $180 a year of coverage on the SOLIX and $800 on the Yeti for the identical term.
Portability & Form Factor
Selected because: One unit rolls on wheels at 67.2 lbs; the other is a 115.7-lb two-person lift listed as stationary, which decides every use where the power has to travel.
weight
Sixty-seven pounds is a suitcase you wheel to the car; a hundred sixteen is a two-person, mind-your-back lift that reviewers flag as fixed-in-placeB1, and Goal Zero's own spec lists it as stationary, the tactful way of saying it lives where you unbox it. The SOLIX ships with 4.72-inch wheels and a retractable handle that owners name as the top reason they chose it over similar-spec rivalsA1. One of these has a travel plan. The other has an address.
Your Life, Your Pick
Selected because: Six real load-outs show the split cleanly: the Yeti wins when it can sit still, the SOLIX wins the moment the job requires moving.
Line up all six load-outs and a rule falls out: when the unit can sit still and the load is heavy, the Yeti's capacity wins; the moment the power has to travel, capacity you can't carry counts for nothing. The Yeti takes the 8-hour blackout and the remote workday on reserve. The SOLIX takes the tailgate, not by being bigger but by being the only one that shows up. Two scenarios beat both: a full RV weekend, where the SOLIX runs short on energy and the Yeti has it but won't travel, and a 4,685Wh van-life day that's more than either unit finishes. Match the winner to how you'll actually use the thing, not to the nameplate.
What the Specs Don't Tell You
Selected because: The Yeti's one genuine edge is surge, 7,200W against 2,800W, set against its 49-lb weight penalty and slightly longer cycle life.
rated cycles
Three catches fire, and they don't all point the same way. Weight and cycle life pull against each other: the Yeti's 49-lb penalty is also the price of its longer life, 4,000 cycles and about 11 years to the SOLIX's 3,000 and 8.2. The third, surge, is the Yeti's genuine edge, its inverter has the headroom to start heavy motors that the SOLIX's thinner margin doesn't, which is the one place the Yeti's price actually buys capability instead of just more of the same. Longer-lived, harder to move, and better with a compressor: that's the Yeti, and none of it is free.

Two nights off-grid with essential comfort
Neither unit
Neither gives you a powered weekend: the Yeti PRO 4000 has the energy but doesn't travel, and the SOLIX F2000 covers about 83% of the 2,100Wh. One can't go; the other can't finish.

8-Hour Blackout
Keep the essentials running through a night without power
Yeti PRO 4000
Both make it through the night; the Yeti makes it through the next one too. It finishes at 48% used with 1,750Wh in reserve, call it another full evening, while the SOLIX ends at 94% with 96Wh, essentially empty. If your outages reliably end by morning, the SOLIX is plenty. If they creep past a day, that reserve is the entire reason to own the Yeti.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
A CPAP pulls about 40W for eight hours, so both units end the night barely touched, the SOLIX at 18% used, the Yeti at 9%. Capacity decides nothing here. Neither publishes a noise figure, so the one thing that might wake you, a fan kicking on at 2 a.m., is unspecified on both. Buy on price and weight, and know you're choosing a fan you haven't heard.

SOLIX F2000
This is the SOLIX by forfeit and on merit. The Yeti's 115.7 lbs don't make it to a tailgate, and even if they did, 670Wh is nothing either unit strains against, the SOLIX covers it with 1,071Wh to spare. The only power station that shows up in the parking lot is the one that fits in the trunk.

Conclusion
August 30, 2026
Verdict: the Anker SOLIX F2000
Take the SOLIX F2000 unless you specifically need a stationary install near 4,000Wh. At $900 against $4,000 it's cheaper to buy and cheaper to own per kilowatt-hour, and at 67.2 lbs on wheels it actually travels to where you need power, which the 115.7-lb Yeti does not. The Yeti's advantages are narrow but real: nearly double the usable energy, a 7,200W surge ceiling for heavy motor loads, and 3,000W of solar that refills it fast, all of which suit whole-home backup or an off-grid setup with big compressors. For camping, RV trips, blackouts, and everyday backup, you'd be paying four times the price for capacity you can't move and energy that costs more per kilowatt-hour, not less.

Runtime model
Runtime = (rated capacity × 0.85 inverter efficiency) ÷ device wattage. Solar recharge estimates assume panels deliver 70% of rated output. Cold weather, battery age, and stacked loads reduce real-world results.
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 F2000 rates 3.7/5 (24th percentile of 26 Large-class units), and Yeti PRO 4000 rates 3.6/5 (20th percentile of 16 Home Backup-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.
Weight Reality Check
Neither unit is grab-and-go. The SOLIX F2000 (67.2 lbs) is manageable solo but heavier than a large checked suitcase. The Yeti PRO 4000 (115.7 lbs) is firmly a two-person lift. It goes where you put it and stays there. That's a 49 lb difference, and it is paid once — getting the heavier one into position, not every time you move it.
The surge headroom is the Yeti's, and it's real
This is the one spec where paying up for the Yeti buys something concrete. Its inverter peaks at 7,200W, double its continuous rating, against the SOLIX's 2,800W, about 1.2x. Motor loads like fridges, AC compressors, pumps, and tools spike two to three times their running draw at startup, and a thin surge margin is exactly what trips then. Run one such appliance and the SOLIX is fine; start several together and the Yeti is the safer inverter.
UPS Switchover: ≤15ms vs ≤20ms
Both list a UPS mode, at different rated speeds. The Yeti PRO 4000 is rated ≤15ms — fine on paper for routers and most electronics; the fussiest PC power supplies sit right at this line. The SOLIX F2000 is rated ≤20ms — fine on paper for routers and most electronics; the fussiest PC power supplies sit right at this line. If a computer with unsaved work is the thing being protected, the stated class is worth the attention; nothing here is a lab result.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here. Worth saying because the per-dollar framing can suggest otherwise: the SOLIX F2000 works out at 5.6 years of cover per $1,000 spent against the Yeti PRO 4000's 1.3, but that spread is the price gap, not the terms.
Battery Lifespan in Real Years
The Yeti PRO 4000 is rated for 4,000 cycles vs 3,000. In real life: at daily use, that's 11 vs 8.2 years. At weekend use (twice a week), it's 38 vs 29 years. One caution reading years across different sizes: a cycle is 3,994Wh on the Yeti PRO 4000 and 2,048Wh on the SOLIX F2000, so count lifetime energy — roughly 15,976 kWh against 6,144 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.
Full record above — the Test Desk pick is the SOLIX F2000.

Brand trust
Anker
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
Reach from Anker's consumer-electronics business, InfiniPower LFP built for long cycle life, and genuinely strong dollar-per-watt-hour in the mid and larger sizes, the F2000 included.
Worth knowing
Anker's support used to be the calling card, fast, no-hassle replacements, but recent SOLIX-specific reports describe AI-driven first-line agents and awkward return logistics for heavy units that ship as hazmat. The broader Anker trust is intact; the SOLIX support experience is trending down from it.
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
The heritage name in portable power, US-based, ruggedized, weather-resistant builds and a Yeti-Ready ecosystem of coolers, solar panels, and vehicle kits for people who want to build around one platform.
Worth knowing
Goal Zero's premium price used to come with premium support. Reports from 2025-2026 describe long waits, unanswered email, and tickets sitting for weeks, and the official community forums were recently shut down. On a $4,000 unit that already carries mixed reliability reports, responsive support matters more, not less.
Analyst note
Neither brand's support is what it once was, so don't pay the Goal Zero premium expecting white-glove service; both are US-based with first-line support that's slipped. What stays true is price position: Anker plays value-to-mid, Goal Zero sits at the premium end, and on this particular pairing the gap between them is about as wide as the catalog gets.

Goal Zero Yeti PRO 4000
The Yeti draws real praise and a real warning in the same breath. Reviewers call it one of the most durable builds they've handled, with 3,000W solar that reportedly refills it from 0 to 100% in under two hours off-grid, plus a strong app and US-based supportB1B2. The warning is reliability: owner reports run mixed, with several 12V errors surfacing, including a first unit returned or replaced and a second that threw a 12V error and wouldn't charge from solarB3. On a $4,000 purchase, that's not a footnote. Independent reviewers still rate the roughly 3,994Wh capacity highly for RV and camping backupB4.

Claims are weighted by how specific they are, whether the commenter owns the unit, and how many readers agreed. Comments that mention a product under a rival's review count for more, because the commenter had no reason to be there. This is what buyers report, not our test results — for measurements we ran ourselves, see the methodology.
Who Should Buy Which
Buy the SOLIX F2000 if you…
- →You want one station that covers the realistic list, RV fridge, CPAP, phones, a TV, a couple of kitchen gadgets, and you'd like to wheel it from garage to campsite without recruiting a second personA1A3.
- →You're value-driven: $900 for 2,048Wh at fifteen cents a lifetime kilowatt-hour is simply the better deal per unit of energy.
- →Your outages are the ordinary one-evening kind, and 1,741Wh of usable energy with a bit of slack covers your night.

Buy the Yeti PRO 4000 if you…
- →You're building a fixed backup, house, cabin, or off-grid base, where the unit sits in one spot and needs close to 4,000Wh on tap, so 115.7 lbs is beside the point.
- →Your load list includes heavy motor startups, a well pump, a big fridge and AC running together, shop tools, and you want the 7,200W surge headroom the SOLIX can't match.
- →You have serious solar: 3,000W of input refills the bank fast and gives the Yeti the stronger off-grid growth path as you add panels and capacity.
If neither fits
If your real need is a fully powered RV weekend or genuine van-life daily draw, neither one finishes the job alone, the SOLIX runs short of a 2,100Wh weekend, the Yeti won't travel to it, and a 4,685Wh van-life day is beyond both. That buyer wants a larger portable built to move in the 4-6kWh class, or a pair of units sharing the load, rather than either of these on its own.
The Bottom Line
The SOLIX F2000 is the buy for almost everyone asking. It's less than a quarter of the Yeti's price, cheaper per kilowatt-hour to own, and at 67.2 lbs on wheels it goes where you need power instead of waiting in the garage for you to need it there. The Yeti's nearly-double capacity is real, but it's pricier energy in a box one person can't lift, and its best case is narrow.
Buy the Yeti PRO 4000 if you're wiring a fixed backup that needs close to 4,000Wh and the surge to start heavy motors, where 116 lbs never has to move. Everyone else: take the wheeled unit, keep the difference, and don't look back.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the Goal Zero Yeti PRO 4000 worth four times the price of the Anker SOLIX F2000?
Only if you need what the extra money actually buys: a fixed install near 4,000Wh, 7,200W of surge headroom, and 3,000W of solar. For whole-home backup, an off-grid cabin, or heavy motor loads, yes. For camping, RV trips, and everyday backup, no, the $900 SOLIX covers those and costs less per lifetime kilowatt-hour ($0.15 versus $0.25).
Can one person move the Yeti PRO 4000?
Not comfortably. At 115.7 lbs it's a two-person lift, and Goal Zero lists it as a stationary unit. The SOLIX F2000 is 67.2 lbs and ships with wheels and a retractable handle, so one person can roll it to a car or campsite. When the unit has to travel, that 49-lb gap decides it.
Which is better for RV and camping, the SOLIX F2000 or the Yeti PRO 4000?
The SOLIX F2000, mainly because it can come along. It handles the usual RV list, fridge, CPAP, lights, fans, a TV, and rolls on its own wheels. The Yeti holds more energy, but at 115.7 lbs and stationary it's built to stay put, which makes it the worse travel companion despite the bigger battery.
Will the Anker SOLIX F2000 run a fridge and an air conditioner at the same time?
One at a time, comfortably; both starting at once is where it gets risky. Its 2,800W surge is only 1.2x its 2,400W continuous rating, so simultaneous compressor startups can trip it. The Yeti's 7,200W surge, 2x its rating, has far more room for stacked motor loads. For a single fridge or a CPAP, the SOLIX is fine.
How long do these batteries last?
The SOLIX is rated for 3,000 charge cycles, roughly 8.2 years of daily use; the Yeti for 4,000 cycles, about 11 years. Neither dies at that mark, LFP cells settle to around 80% of original capacity and keep going. Counting total energy over their rated lives, the Yeti stores more (15,976 kWh versus 6,144), but each kilowatt-hour costs more.
