Head-to-head test
Anker SOLIX S5000 vs Goal Zero Yeti 3000X
The Yeti 3000X costs more than the S5000 and gives back less of everything except a lighter lift: a twentieth of the lifetime energy, under half the output and a fifth of the solar input.

Spec deltas
The Goal Zero Yeti 3000X costs $500 more than the Anker SOLIX S5000 and loses nearly every line after the price. The S5000 carries 5,024Wh of LiFePO4 against 3,032Wh of NMC, runs 4,500W where the Yeti runs 2,000W, and takes 3,000W of solar to the Yeti's 600W. Take the S5000.
Cycle life is where the gap stops being a gap and becomes a different category of product. Anker rates the S5000 for 6,000 cycles to 80% capacityA12; the Yeti's NMC pack is rated for 500B1. Multiply each by its capacity and the S5000 moves about 30,144kWh over its rated life, the Yeti about 1,516kWh. One is a battery you keep for well over a decade. The other you start replacing in your second year of daily use.
The Yeti's honest wins are physical. It weighs 69.78 lb to the Anker's 97, and it has a 12V car socket, which the S5000 doesn't. If you're loading the unit into a vehicle by yourself, those 27 lb are real. For anything that stays at home, they aren't worth paying more for.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
cost / lifetime kWh
Set against what each costs, a kilowatt-hour from the S5000 runs $0.08 and one from the Yeti $1.98. The Yeti isn't the premium pick with premium staying power. It's the dearer battery that wears out first.
S5000: 5,024Wh, rated 6,000 cycles to 80%A12Yeti 3000X: 3,032Wh NMC, rated 500 cyclesB1Cost per lifetime kWh: $0.08 vs $1.98
Why it mattersAnyone planning daily or weekly cycling, for an RV or solar self-consumption, can rule the Yeti out on this chain alone.
continuous output
In an outage that's the difference between running the fridge and the sump pump together and deciding which one gets the plug. With two AC outlets, the Yeti makes that choice for you before its inverter even has to.
S5000: 4,500W rated, 8,000W peak, L14-30R at 240V split-phaseA2A14Yeti 3000X: 2,000W rated, 3,500W surgeB3AC outlets: 6 on the S5000, 2 on the Yeti
Why it mattersAnyone wiring a unit into a transfer switch, or running a 240V well pump, needs the S5000; the Yeti has no 240V output.
solar input
That's a morning against a whole solar day, and the gap widens if you grow the system. The Yeti grows into lead-acid that gives back about half its rating and halves the onboard lithium when connectedB4; the S5000 grows in 5,024Wh LiFePO4 packs to 30,144WhA6, with the solar input to actually refill them.
S5000 solar input 3,000W across two inputsA5Yeti 3000X solar input 600WYeti expansion is a lead-acid Tank with about 50% usable capacityB4
Why it mattersOff-grid and outage buyers who plan to add panels or batteries should treat the Yeti's expansion path as a dead end.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: Twenty times the rated lifetime energy for less money is the gap that decides this pair.
cost / lifetime kWh
$1.98 per kilowatt-hour is what the Yeti's battery costs you across its rated life, against $0.08 for the S5000. Careful use doesn't close that: the NMC pack is rated for 500 cyclesB1, and daily use reaches that in about 1.4 years.
Warranty points the same way, 5 years on the S5000 against 2 on the Yeti. The cheaper unit is also the one its maker stands behind longer.
Runtime: Will It Power Your Gear?
Selected because: Both clear a blackout night, but only one has most of a second night left over.
continuous output
On the 8-hour blackout load the S5000 finishes with 2,625Wh left and the Yeti with 932Wh. Call it the second-night test: the S5000 passes it outright, the Yeti gets a little over halfway.
Neither covers the full 4,685Wh van-life day. The S5000 falls 415Wh short, which one sunny morning on 3,000W of solar erases. The Yeti falls 2,108Wh short, which is most of a second Yeti.
Growth Path
Selected because: The S5000 grows in LiFePO4 packs; the Yeti grows in lead-acid.
solar input
Bolt a Tank onto the Yeti and you're adding lead-acid that gives back about half its rated capacity, while the onboard lithium is cut in half for as long as it's connectedB4. The mechanism undoes itself: part of what you add, it takes back from what you already owned.
The S5000 takes up to five BP5000 packs at 5,024Wh each, joined over a 400V DC port, for 30,144Wh in totalA6. If you think your needs will grow, it's the only path on this page that leads anywhere.
Portability & Form Factor
Selected because: The Yeti's one real win is 27 lb less to lift.
weight
At 69.78 lb the Yeti is already a hard one-person lift, which is why it ships with a roll cartB2. The S5000 at 97 lb is harder still, but Anker built it as an upright cabinet on wheels with a pull rod and a foot step for tipping it backA10A11.
If the unit lives in a garage and rolls to an outlet, the difference is a non-event. If it rides in a trunk and you're loading it alone, the Yeti's lighter frame is the strongest card it holds.

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
SOLIX S5000
The Yeti 3000X finishes the weekend at 81% used with 477Wh in hand — one cold night or an extra device eats into that. The SOLIX S5000 finishes at 49% with 2,170Wh, real slack for the spontaneous stuff. If you camp in variable weather, that buffer is the difference between relaxing and watching the battery app.

8-Hour Blackout
Keep the essentials running through a night without power
SOLIX S5000
Both survive the night. The SOLIX S5000 finishes at 39% used with 2,625Wh left — 1.6 more nights like it. The Yeti 3000X finishes at 64% with 932Wh, 57% of a second night. If your outages tend to run past one evening, that difference is the whole argument between them.

SCN-03 · 8 hours · needs 320Wh
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 3000X 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.

SOLIX S5000
The SOLIX S5000 clears the workday at 21% used, banking 3,360Wh — late work, extra calls, or a second laptop charge without arithmetic. The Yeti 3000X at 35% also finishes, with 1,667Wh of slack for the unplanned.

Tailgate Party
Game day power for the crew
SOLIX S5000
Both handle game day; the SOLIX S5000 keeps more in reserve (16% used vs 26%). Tailgating is a light load, though, so the number you'll feel is weight: 69.8 lbs for the Yeti 3000X against 97 lbs for the SOLIX S5000, from the trunk to the setup spot.

Neither unit
Neither unit covers this scenario's 4,685Wh: the SOLIX S5000 comes up 415Wh short (about 91% covered) (its nameplate 5,024Wh actually clears this — the flat 15% conversion allowance is what tips it under), the Yeti 3000X 2,108Wh (55%). Either gets you most of the way, so this is a scenario you plan around rather than one you should rule them out for.

Conclusion
October 9, 2026
Verdict: the SOLIX S5000
The S5000 costs $500 less and beats the Yeti 3000X on capacity, output, solar input, warranty and rated cycles, which puts its energy cost across rated life at $0.08 per kWh against the Yeti's $1.98. Confidence stops at 7 only because nobody has tested the S5000 independently yet; on the specs this isn't close. Pick the Yeti only if 97 lb is impossible for you to move and 27 lb less fixes that.

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 S5000 rates 4.6/5 (74th percentile of 20 Home Backup-class units), and Yeti 3000X rates 3.3/5 (1st percentile of 26 Large-class units).

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 Yeti 3000X (69.8 lbs) is manageable solo but heavier than a large checked suitcase. The SOLIX S5000 (97 lbs) is noticeably heavier. That's a 27 lb difference.
Only the SOLIX S5000 Lists a UPS Mode
The SOLIX S5000 can sit between the wall and your gear and hand it to battery when the grid drops — rated ≤10ms — quick enough on paper that desktop PCs and routers should ride through, treating that as the rating it is. Worth it for a router, a desktop PC, or a CPAP. The Yeti 3000X's spec sheet lists no UPS mode, so anything plugged into it rides an outage only as far as your reaction time.
Warranty: 5 Years vs 2
The SOLIX S5000 is covered for 5 years against the Yeti 3000X's 2 years. An underrated factor if you're keeping this unit for years.
Battery Lifespan in Real Years
The SOLIX S5000 is rated for 6,000 cycles vs 500. In real life: at daily use, that's 16.4 vs 1.4 years. At weekend use (twice a week), it's 58 vs 5 years. One caution reading years across different sizes: a cycle is 5,024Wh on the SOLIX S5000 and 3,032Wh on the Yeti 3000X, so count lifetime energy — roughly 30,144 kWh against 1,516 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.
Yeti 3000X: Noise Level Not Disclosed
The SOLIX S5000 publishes its noise level (30dB); the Yeti 3000X doesn't publish one. That isn't evidence the Yeti 3000X 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 S5000's 30dB as the only published number on the table — a spec-sheet figure, not a measurement — and look for hands-on reports of the Yeti 3000X before deciding.

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
Anker's case for this unit is the spec sheet itself: LiFePO4 rated for 6,000 cycles, 240V split-phase from one box, and UL 9540 and UL 9540A certification.
Worth knowing
Every S5000 figure on this page is Anker's own rating; no independent test exists yet. Anker's support on its larger SOLIX units has also drifted from its old reputation, and returns of a unit this heavy mean hazmat freight.
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
Goal Zero's own store listed the whole X series, the 3000X included, out of stock at our September check, so buying one usually means retailer stock.
Analyst note
Goal Zero has the longer history in portable power; Anker brings the more current battery chemistry to this pair. With a 2-year warranty against 5, that history is the only thing the Yeti's badge adds.

Who Should Buy Which
Buy the SOLIX S5000 if you…
- →The homeowner who wants a 240V outlet feeding a transfer switch, so the well pump and the fridge both run through a storm.
- →The RV owner who'll cycle the battery most days and wants it still holding 80% after thousands of cycles, not hundreds.
- →Anyone building a solar bank that will grow, since the S5000's 3,000W input and LiFePO4 packs scale and the Yeti's lead-acid Tank doesn't.
Buy the Yeti 3000X if you…
- →Someone already invested in Goal Zero coolers and vehicle kits who finds a 3000X priced well under the S5000, and only needs it for occasional outages.
- →The person who has to load the unit into a vehicle alone, can't manage 97 lb, and needs a 12V car socket.
If neither fits
If your outage plan is a phone, a router and a few lights, both of these are overkill. A compact LiFePO4 station covers that at a fraction of either price, and you can carry it with one hand.
The Bottom Line
The Yeti 3000X asks for more money and returns a battery rated for a twelfth of the cycles, under half the output and a fifth of the solar input. The 27 lb it saves you is real, and it's the only thing on its side of the ledger.
Roll the S5000 into the garage, wire it to the panel if you like, and stop thinking about it for years. Buy the S5000.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the Anker SOLIX S5000 better than the Goal Zero Yeti 3000X?
Yes, on nearly every measure in the record. It stores 5,024Wh to the Yeti's 3,032Wh, outputs 4,500W to 2,000W and is rated for 6,000 cycles to 500, while costing $500 less. The Yeti is 27 lb lighter and has a 12V car socket, and that's the whole case for it.
How long will a Yeti 3000X battery last?
Its NMC pack is rated for 500 cycles to 80% capacity. Used daily that's about 1.4 years; used twice a week, about 4.8 years. The S5000's 6,000-cycle rating works out to about 16.4 years of daily use.
Can the Anker SOLIX S5000 run 240V appliances?
Yes. Its L14-30R outlet delivers 120/240V split-phase at up to 4,500W, which suits a well pump or a home transfer switch inlet. The Yeti 3000X has no 240V output.
Can I keep the S5000 in a bedroom to run a CPAP?
Anker's rating label says no: holding more than 1kWh, it belongs in a non-habitable space, outside sleeping rooms. A CPAP night uses about 7% of its capacity, so run an extension cord from the next room or put a small unit at the bedside.
