Spec deltas
The Anker SOLIX C1000 Gen 2 holds 1,024 watt-hours and pushes 2,000 of them; the Goal Zero Yeti 300 holds 297 and stops at 350. Those aren't two sizes of the same tool. They're two different tools, and the only question that matters is which one your loads actually need.
The Yeti is the cheaper box — $350 against $530 — and that $180 is the single best argument for it. But it's the more expensive energy: the same 4,000-cycle life stretched over less than a third the capacity works out to about $0.29 per lifetime kilowatt-hour, against the C1000's $0.13. You save at the register and hand it back in watt-hours you never get.
What the Yeti wins outright is weight: 13.7 pounds and an IP54 shellB2 to the C1000's 24.9. If your ceiling is a few phones, a laptop, and a speaker, that lightness is the entire point and the C1000's spare capacity is just more to carry. For anyone whose day includes an appliance, a full CPAP night, or a real evening of mixed loads, the C1000 Gen 2 is the pick — more capable, and over its life the cheaper watt-hour.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
Run it over the life of the packs and the sticker flips. Same 4,000 cycles, but the C1000 will deliver 4,096 kilowatt-hours to the Yeti's 1,188, which works out to about $0.13 per lifetime kilowatt-hour against $0.29 — more than double. The cheaper box is the more expensive energy.
Yeti 300 $350 vs C1000 Gen 2 $530 — $180 less up frontYeti 300 297Wh vs C1000 Gen 2 1,024Whboth rated 4,000 cycles; lifetime energy 1,188 kWh (Yeti) vs 4,096 kWh (C1000)
Why it mattersIf price is your reason for the Yeti, the math doesn't back you: over its life the C1000 is the cheaper power. Buy the Yeti for its weight, not its cost.
continuous output
So the Yeti is a phones-laptops-lights-and-CPAP unit and nothing heavier; the moment a load has a heating element or a compressor, it's the C1000 or nothing. That's not a capacity gap you close with a longer afternoon. It's a wall between two classes of device.
Yeti 300: 350W continuous, 600W surgeC1000 Gen 2: 2,000W continuous, 3,000W surgeC1000 runs a 1,500W space heater with headroomA3; the Yeti can't approach that class of loadB3
Why it mattersIf your list will ever include a heater, a kettle, a blender, or a fridge, the Yeti isn't a smaller version of the answer. It's the wrong one.
weight
The C1000's extra 727 watt-hours arrive with 11 extra pounds, and for anyone whose day tops out around a hundred watt-hours that's weight you haul and capacity you never spend. This is the one lane the Yeti wins outright, and it wins it cleanly.
Yeti 300: 13.7 lbs, IP54 ratingB2C1000 Gen 2: 24.9 lbsAfternoon Off-Grid (100Wh, phones and a speaker): both units cover it easily
Why it mattersIf your real ceiling is phones, a laptop, and a speaker and you're the one carrying the box, take the 13.7-pound Yeti and let someone else lug the kilowatt-hour.
The specific dimensions that decide these two units — everything else is a tie.
Runtime: Will It Power Your Gear?
Selected because: The gap between a 350W inverter and a 2,000W one decides which loads either unit can physically run.
continuous output
Strip both nameplates to what you actually get and the Yeti 300 leaves about 252 usable watt-hours — its 297Wh, less the flat 85% factor these figures use — which one review clocked at four to six hours on a laptop or twenty to thirty phone chargesB3. That's a genuine workday of small electronics, and honestly all it is. The C1000 Gen 2's 870 usable watt-hours is a different unit of time: an evening of mixed loads, or that same laptop for the better part of two days.
The number that decides more than capacity is the inverter. The Yeti's 350W continuous means one modest device at a time, and it will tell you when you've asked for too muchB3. The C1000's 2,000W keeps several things alive at once. If runtime for you means a fridge, a couple of lights, and a phone all making it through an outage together, only one of these is in that conversation.
Lifetime Value
Selected because: The pricier C1000 is the cheaper energy over its life — $0.13 per lifetime kWh against $0.29 — which reframes the $180 sticker gap.
cost / lifetime kWh
The C1000 Gen 2 is the cheaper energy over its life, but that verdict has a fair-sized asterisk and it's worth saying out loud. Its $0.13-per-lifetime-kilowatt-hour edge only cashes if you actually cycle the capacity. A buyer who genuinely never draws more than a hundred watt-hours a day never spends those extra kilowatt-hours, and so never collects the discount; they just paid $180 more for headroom that sits idle.
So read the lifetime-value line as conditional, not automatic. If your loads are real — an evening of appliances, a work-from-anywhere setup, an outage you actually ride out — the C1000's cost per watt-hour is the honest number, and it's decisively lower. If your loads are tiny and fixed, the Yeti 300's higher $0.29 is a figure you'll never really pay, because you'll never draw the watt-hours to trigger it.
Portability & Form Factor
Selected because: Eleven pounds and an IP54 build are the Yeti 300's one clear advantage, and for light loads that's most of the decision.
weight
Portability is the Yeti 300's home turf, and it earns the title on more than the scale. It's 13.7 pounds to the C1000's 24.9, but it's also IP54-rated against dust and water, with rubberized corners and a handle reviewers call genuinely solidB2 — the kind of unit you don't think twice about tossing in a wet canoe or leaving out on a job site. The C1000 is remarkably light for a 1kWh station, but it's a two-hand lift, and ruggedness is the Yeti's column here.
That build is a real, specific reason to choose the smaller unit, not a consolation prize. If the box is going to live outdoors, get rained on, and be carried by one person, the Yeti was made for exactly that. Just don't confuse built to go anywhere with big enough to do everything; those are different questions, and this section only answers the first.
Your Life, Your Pick
Selected because: The load-by-load grid shows where each unit lands — and that the Yeti wins only the smallest job on the board.
Run the two across a full slate of real days and the pattern is stark. The only row where the Yeti 300 is the call is the 100-watt-hour Afternoon Off-Grid job — phones and a speaker — where both units cover it with room to spare and it comes down to the Yeti's 13.7 pounds. Every step up from there tilts to the C1000, which takes the CPAP night and the tailgate outright while the Yeti falls short on both.
The other half of the grid is a reality check on both units. Weekend Camping (2,100Wh), an 8-Hour Blackout (1,645Wh), and Van Life Daily (4,685Wh) are misses for each of them — the C1000 covers more of each, but more of a miss is still a miss. The one near-thing is the 910Wh Remote Workday, where the C1000 lands about 40 watt-hours short and a single trimmed appliance gets you there. Read the grid honestly and it says the C1000 is the bigger tool, but if your days look like those three rows, you want a bigger tool than either.

Neither unit
Neither unit covers this scenario's 1,645Wh: the SOLIX C1000 Gen 2 comes up 775Wh short (about 53% covered), the Yeti 300 1,393Wh (15%). This is well outside what either unit is for; the right answer here is a larger station, not a choice between these two.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
SOLIX C1000 Gen 2
A 40W CPAP over a full night wants about 320 watt-hours. The C1000 Gen 2 finishes with 550 to spare; the Yeti 300 comes up roughly 68 short and gives out before the alarm. Run a basic machine without a humidifier and the Yeti might sneak through, but if it's your breathing, that 68-watt-hour gap is the difference between a night and most of one.
Battery budget usedlower = more headroom
LOAD CPAP Machine 40W×8h

Remote Workday
Full work day off-grid without power anxiety
Neither unit
Neither unit quite closes a 910Wh workday, but only one gets within sight of it: the C1000 Gen 2 lands about 40 watt-hours short, so trimming one appliance or accepting a slightly shorter evening gets you there. The Yeti 300, 658 short, was never in this race. Call it a narrow miss for one and a no-show for the other.

Tailgate Party
Game day power for the crew
SOLIX C1000 Gen 2
The Yeti 300 can light the 400W peak — its 600W surge gets it moving — but the 350W continuous rating can't hold it, so it starts your setup and then quits under it. The C1000 Gen 2 runs the whole tailgate with 200 watt-hours to spare. If there's a blender or a griddle in the plan, that's the difference between a party and a false start.

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 300 4,433Wh (5%). This is well outside what either unit is for; the right answer here is a larger station, not a choice between these two.

Afternoon Off-Grid
Phones and a speaker at the park, beach, or campsite — the small-unit job description
Either unit
This row is here for the Yeti 300's class of job: phones and a speaker, 100Wh across an afternoon. Both cover it — the Yeti 300 finishes at 40% used, and the SOLIX C1000 Gen 2 barely notices it. For this job the SOLIX C1000 Gen 2's extra capacity is dead weight, not headroom; take the Yeti 300 at 13.7 lbs and leave the rest at home.

Conclusion
August 30, 2026
Verdict: the SOLIX C1000 Gen 2, on Power Score margin
Take the C1000 Gen 2. It holds more than three times the energy (1,024Wh vs 297Wh), runs real appliances the Yeti's 350W inverter can't touch, and still comes out cheaper per lifetime kilowatt-hour ($0.13 vs $0.29) — so the Yeti's $180 lower price is the only cost round it wins, and even that only holds if you never use the extra capacity. The Yeti 300 is a genuinely good light-duty unit: 13.7 pounds, IP54, and the right call for the buyer whose daily loads stay well inside its 297WhB2. But most people weighing a sub-300Wh station against a 1kWh one have already outgrown the smaller box.

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 300 rates 3.7/5 (24th percentile of 22 Personal-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
Expandable, But Don't Over-Weight It
The C1000 Gen 2 can bolt on expansion batteries and the Yeti 300, sealed at 297Wh, can't — a real difference, but not one that should decide this. At this size, extra batteries buy longer runtimes on the same loads, not a jump to whole-home backup, and most buyers never add one. Treat expandability as a mild tiebreaker in the C1000's favor, not a headline reason to choose it.
UPS Switchover: ≤10ms vs ≤20ms
Both list a UPS mode, at different rated speeds. The SOLIX C1000 Gen 2 is rated ≤10ms — quick enough on paper that desktop PCs and routers should ride through, treating that as the rating it is. The Yeti 300 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 Yeti 300 works out at 14.3 years of cover per $1,000 spent against the SOLIX C1000 Gen 2's 9.4, but that spread is the price gap, not the terms.
Yeti 300: Noise Level Not Disclosed
The SOLIX C1000 Gen 2 publishes its noise level (35dB); the Yeti 300 doesn't publish one. That isn't evidence the Yeti 300 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 300 before deciding.
Full record above — the Test Desk pick is the SOLIX C1000 Gen 2.

The Yeti 300 is cheaper to buy, but the SOLIX C1000 Gen 2 is cheaper to own. At $0.13/kWh over its lifetime vs $0.29/kWh, the SOLIX C1000 Gen 2's higher cycle life and capacity make each dollar go further over the years. One thing to know reading the table: both carry the same 4,000-cycle rating, so the lifetime rows are sticker price and capacity in disguise — the wear horizon is identical and decides nothing here.

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 edge is value per watt-hour — the C1000 sits among the better-priced units in its own catalog on a dollars-per-watt-hour basis — backed by the parent brand's consumer-electronics reach and an app that rates well (4.5/5 on iOS).
Worth knowing
SOLIX-specific support has drifted from Anker's old no-hassle-replacement reputation toward slower, more generic handling, and firmware updates have occasionally removed features without notice. The hardware value is real; just set your support expectations to fine, not legendary.
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
Goal Zero is the category's pioneer and still builds like it: a US-based company with ruggedized, weather-resistant designs and a loyal following in overlanding and preparedness circles.
Worth knowing
The old premium-price-buys-premium-support bargain is weakening. Recent reports describe long waits and unanswered tickets, the official community forums were shuttered, and the app's newer reviews skew toward connectivity and stability complaints. You're paying a heritage premium now, not a service one.
Analyst note
Both brands' support has slipped from their better days, so neither earns a clear service edge here — which throws the decision back onto the hardware. There, Anker brings more watt-hours per dollar and Goal Zero brings ruggedness and heritage. For the buyer cross-shopping these two, the watt-hours win.

Analyst note
The Yeti 300 is sealed at 297Wh, which is fine if that covers you. The SOLIX C1000 Gen 2 starts at 1,024Wh and can grow beyond it with Anker 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.
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 rate the C1000 Gen 2 the mid-size unit to beat in 2026A4, and the two upgrades they keep pointing to are speed and output: a full recharge in roughly 49 minutesA1, and enough continuous power to run a 1,500W space heater with headroom the original didn't haveA3. It reads as a refined, fast-charging update to a platform that was already popularA4.
The recurring gripe is noise. The single most common complaint is the fan: nearly silent under about 200W (around 35dB), but ramping to roughly 55dB when it's fast-charging or pushing heavy outputA2. That's the tax on the quick recharge, and it's worth knowing if the unit will share a room with you at night.
“Fast HyperFlash charging — a full recharge in roughly 49 minutes, noticeably quicker than the original C1000's ~58-80 minutes.”

Goal Zero Yeti 300
Field reports like the Yeti 300 for what it is: a modern LiFePO4 pack rated 4,000-plus cycles behind a 350W pure-sine inverter, built for long service life rather than raw outputB1. The build draws praise — 13.7 pounds, IP54 dust-and-water resistance, rubberized corners, and a 50-minute rechargeB2.
The steady caveat is what 297Wh can and can't do. One review put it at four to six hours on a laptop or twenty to thirty phone charges, and one owner's unit shut down two minutes into a coffee maker as it neared its 300W limitB3. At $350, one reviewer flagged the price as steep for the capacityB4 — a fair note, and the reason this comparison keeps circling back to watt-hours per dollar.

Who Should Buy Which
Buy the SOLIX C1000 Gen 2 if you…
- →Anyone running an actual appliance. A 1,500W space heater, a coffee maker, a blender, a small fridge — loads that need more than 350 watts — only clear the C1000's 2,000W inverterA3.
- →The overnight and medical-load user. If it has to carry a CPAP through a full night, or keep a couple of things running through an outage, the C1000's 1,024Wh finishes the job with margin where the Yeti runs out.
- →The value buyer who will use the capacity. If you'll genuinely cycle it, the C1000's $0.13 per lifetime kilowatt-hour is the lowest cost per unit of energy on this page — you pay $180 more today to pay less per watt-hour for years.
Buy the Yeti 300 if you…
- →The sub-300-watt-hour buyer. Phones, a laptop, a camera, a speaker, some lights — if your day genuinely fits inside the Yeti 300's 297Wh, the extra capacity next door is money and weight you won't use.
- →The person who carries it into the weather. At 13.7 pounds with an IP54 ratingB2, the Yeti is the one you take in a canoe, on a hike, or onto a job site in the rain without babying it.
- →The buyer who wants the lowest price today and means it. The Yeti is $180 less at the register, and if your loads are small and fixed, that upfront saving is real money you keep.
If neither fits
Anyone sizing for the house. A full 8-hour blackout runs about 1,645Wh here, a weekend of camp loads with a fridge about 2,100Wh, and van-life daily draw about 4,685Wh — and both of these miss all three, the Yeti badly and the C1000 by less. Point yourself at a 2kWh-plus station; the C1000's 2,000W inverter is already strong enough, it's the watt-hours that run out.
The Bottom Line
The C1000 Gen 2 is the more capable unit and, against intuition, the cheaper energy: $0.13 per lifetime kilowatt-hour to the Yeti 300's $0.29, because the same 4,000-cycle life spread across more than three times the capacity is what that extra $180 actually buys. It also does things the Yeti physically can't — hold a 400W peak, run an appliance, finish a full CPAP night — none of which its 350W inverter can reach.
The Yeti 300 answers on one axis and answers it well: 13.7 pounds and an IP54 shell you can toss in a wet canoeB2, for the buyer whose loads never leave the world of phones, a laptop, and a speaker. That buyer should take it happily and pocket the weight. Everyone else is holding a sub-300Wh unit up against a 1kWh one precisely because they've already outgrown the 300 — and for them the answer is the Anker.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the Goal Zero Yeti 300 big enough to run a CPAP all night?
Not with much margin. A 40W CPAP over a full night needs roughly 320 watt-hours, and the Yeti 300 gives you about 252 usable — it comes up around 68 short and runs dry before morning. A basic machine without a heated humidifier draws less and might just make it, but if you'd rather sleep than do power math, the C1000 Gen 2 covers the same night with 550 watt-hours to spare.
Why is the more expensive Anker C1000 Gen 2 the cheaper one 'per watt-hour'?
Because the extra money buys far more energy. The C1000 holds 1,024Wh to the Yeti 300's 297Wh, and both packs are rated for 4,000 cycles — so across its life the C1000 delivers 4,096 kWh at about $0.13 each, against the Yeti's 1,188 kWh at about $0.29. The Yeti is the cheaper box on the shelf; the C1000 is the cheaper electricity out of it, provided you actually use the capacity.
Can the Yeti 300 run kitchen appliances or a fridge?
Only the smallest ones. Its inverter is rated 350W continuous with a 600W surge, so anything with a heating element or a compressor is out — a kettle, a hair dryer, most fridges, even a coffee maker sit past its 350W ceiling. The C1000 Gen 2's 2,000W (3,000W surge) runs a 1,500W space heater with room left over. If appliances are on your list, this isn't a close call.
Which one is more portable?
The Yeti 300, and it isn't close on paper: 13.7 pounds against 24.9, with an IP54 dust-and-water rating and a build reviewers single out for its rubberized corners and solid handle. The C1000 is light for a 1kWh station but it's still a two-hand lift. If you carry it on foot or out into the weather, the Yeti wins; if it lives in a trunk or a closet, the eleven-pound difference stops mattering.
Do the Anker C1000 Gen 2 and Yeti 300 have the same warranty?
Yes — both carry a 5-year warranty, so coverage isn't a tiebreaker. The per-dollar math can make the Yeti look better protected, at about 14.3 years of cover per $1,000 spent versus the C1000's 9.1, but that spread is just the price difference, not better terms.
