Head-to-head test
Anker SOLIX C300 vs Goal Zero Yeti 300
Strip away the $110 price gap and these two land within a penny of each other on cost per lifetime kilowatt-hour, so the real decision isn't about savings at all — it's whether you want the lighter, cheaper, fully-specced unit or 1,000 more charge cycles and double the solar input.

Spec deltas
The Anker SOLIX C300 holds 288Wh and costs $239.99. The Goal Zero Yeti 300 holds 297Wh — nine more watt-hours, practically a rounding error — and costs $349.95. You're not buying more battery for that extra money; you're buying something else entirely.
What that something else actually is: 1,000 more charge cycles (4,000 against 3,000), a 200W solar input double the Anker's 100W, and 350W of continuous output instead of 300W. None of it shows up in the lifetime math — both units land within a penny of each other at $0.28 and $0.29 per kWh over their service lives — so you're paying for headroom, not savings.
The C300 is also 4.6 lbs lighter, at 9.1 lbs against 13.7, and Anker tells you exactly how loud it runs: 25dBA. Goal Zero doesn't publish a number for the Yeti 300 at all. For most buyers who aren't leaning on solar as a primary recharge method, that combination settles it in the Anker's favor.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
The Yeti's higher sticker isn't buying more energy or cheaper storage. It's buying 1,000 more charge cycles (4,000 against 3,000) and double the solar input (200W against 100W) — real specs, but ones that only pay off if you cycle the battery hard or recharge from the sun as your main method.
Anker SOLIX C300 costs $239.99 for 288Wh; Goal Zero Yeti 300 costs $349.95 for 297WhThe engine prices lifetime cost at $0.28 per kWh for the Anker and $0.29 per kWh for the Yeti
Why it mattersA buyer who plugs in nightly and rarely tops up with solar gets nothing extra for the $110 and should buy the cheaper unit.
solar input
That gap is invisible on a nightstand where both units just get plugged into the wall overnight, but it's the whole story for anyone recharging off-grid, where the Yeti turns a lost afternoon of sun into a lost hour.
Anker rates 100W max solar input against the Yeti's 200WBoth units hold nearly identical capacity — 288Wh and 297Wh
Why it mattersVan-life and remote-camping buyers who count on solar as the primary recharge method should pay the Yeti's premium; everyone charging from an outlet shouldn't.
Neither fact alone is disqualifying — coffee makers spike hard on startup, and an unpublished dB rating isn't proof of a loud fan — but together they make the Yeti the less-known quantity of the two, while the Anker's spec sheet holds no surprises.
Anker discloses a 25dBA noise rating; Goal Zero publishes no noise spec for the Yeti 300Owners report the Yeti struggled to run a coffee maker near its rated output limit, shutting down after about two minutesB3
Why it mattersBuyers who value knowing exactly what they're getting before it ships should weight that toward the Anker.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: Near-identical cost per kWh ($0.28 vs $0.29) is the whole ballgame — the price gap doesn't buy cheaper ownership, it buys cycles and solar headroom.
cost / lifetime kWh
Run each unit over its full service life and the numbers nearly converge: $0.28 per kilowatt-hour for the Anker against $0.29 for the Yeti. That penny of daylight is the whole story on ownership cost — neither unit is meaningfully cheaper to run than the other.
What actually differs is the yearly cost of the warranty itself: $48 a year on the Anker's 5-year term against $70 a year on the Yeti's, purely a function of the higher sticker price on an identical five-year term. If ownership cost is your only lens, the Anker wins it outright; the Yeti's higher cycle count is a separate argument about longevity, not price.
Portability & Form Factor
Selected because: The 4.6 lb gap (9.1 vs 13.7) is the most tangible day-to-day difference for anyone actually carrying these.
weight
9.1 lbs against 13.7 lbs is a real difference in the hand — the Yeti weighs about half again as much as the Anker. Neither unit is heavy in absolute terms, but if this is riding in a backpack or getting handed between a tent and a car all weekend, the Anker is the one you forget you're carrying.
The Yeti's extra weight buys real hardware: a bigger continuous output rating (350W against 300W) and the doubled solar input covered above. It's not dead weight, but it is weight.
Your Life, Your Pick
Selected because: Both fail every modeled scenario outright, but Tailgate Party is a dead-heat worth calling out.
Both units fail every scenario the engine models, from an 8-hour blackout to a weekend camping trip — these are device-charging units, not blackout backups, and sizing either one for anything past keeping phones and a laptop alive is the wrong exercise.
The one genuine tie: Tailgate Party lands both units at exactly 100% of the modeled need, capacity spent to the last watt-hour with nothing held in reserve. Neither wins that one; it's a coin flip you settle on price, and price already points at the Anker.
What the Specs Don't Tell You
Selected because: Noise disclosure, warranty value, and cycle life are the concrete, spec-true tiebreakers here.
rated cycles
Goal Zero doesn't publish a noise rating for the Yeti 300 at all — a real omission next to Anker's disclosed 25dBA, and the kind of gap that matters precisely because you can't compare what one side won't state.
Warranty terms are identical at 5 years on paper, but cost-per-warranty-year splits them: $48 for the Anker, $70 for the Yeti. The Yeti's 4,000-cycle rating against the Anker's 3,000 is real and will matter to a buyer running this thing hard daily — everyone else is paying for years they won't use.

Conclusion
July 14, 2026
Verdict: the Anker SOLIX C300
Take the SOLIX C300. It's $110 cheaper, 4.6 lbs lighter, and Anker actually publishes a noise rating (25dBA) where Goal Zero doesn't say a word about the Yeti 300's fan. The two units cost almost the same to own over a lifetime — $0.28 per kWh for the Anker against $0.29 for the Yeti — so the extra 1,000 charge cycles and doubled 200W solar input on the Yeti don't translate into real savings, only into a longer runway you'll only cash in if you actually cycle the battery that hard or lean on solar as your primary recharge method. If that's you, take the Yeti; if not, keep the $110.

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 C300 rates 4.4/5 (67th percentile of 22 Personal-class units), and Yeti 300 rates 4.0/5 (43rd percentile of 22 Personal-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
Same Five Years, Different Yearly Cost
Both carry a 5-year warranty, but the sticker price splits what that coverage costs per year: $48 for the Anker, $70 for the Yeti. Identical protection, different price of admission.
1,000 More Cycles, If You'll Use Them
4,000 cycles against 3,000 sounds decisive until you check the lifetime cost per kWh — $0.28 versus $0.29. The extra cycles extend how long the Yeti lasts under hard daily use; they don't make it a cheaper unit to own.
One Spec Sheet Has a Blank Where the Fan Rating Should Be
Anker publishes 25dBA for the C300. Goal Zero doesn't publish anything for the Yeti 300's fan noise — not a claim it's loud, just a claim you can't check before you buy.

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
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 — 5-6 active portable power station models across Yeti and Yeti Pro series, 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 (IPX4). Integrated "Yeti-Ready" ecosystem with coolers, lights, and vehicle kits.
Worth knowing
Widely acknowledged as the most expensive brand (lowest Wh per dollar). 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
Goal Zero positions itself as a premium brand with stronger support infrastructure, while Anker competes on value. The question is whether the Goal Zero ecosystem and support premium is worth it for your use case.

Reviewers single out two things on the C300: a genuinely compact, light build aimed at keeping phones and small gadgets charged through a hike or weekend tripA1A2, and a 10ms UPS switchover that's legitimately rare to see at this size and priceA3. Anker markets it as roughly 30% smaller than competing stations, and the hands-on coverage backs that framing up rather than rolling their eyes at itA2.
The buyer profile reviewers describe is specific: someone who wants smart features and a compact footprint over raw capacityA4 — closer to a large power bank with an AC outlet than a load-bearing power station.

Goal Zero Yeti 300
The most consistent note on the Yeti 300 across reviewers is the price sting — it's a modern LFP unit with a real 4,000-cycle rating, but the price draws comment even in otherwise-positive coverageB4. That's the same complaint the SOLIX C300 answers directly, for $110 less.
Reviewers do credit the underlying hardware: a genuine LiFePO4 battery rated for over 4,000 cycles, paired with a pure sine inverterB1. But at least one review flagged the rated output ceiling getting tested by a real load — a coffee maker tripped the unit after about two minutesB3, a data point worth knowing if your use case pushes anywhere near the top of what it can deliver.

Who Should Buy Which
Buy the SOLIX C300 if you…
Buy the Yeti 300 if you…
- →You recharge primarily by solar and the doubled 200W input against the Anker's 100W meaningfully shortens your refill time.
- →You expect to cycle this unit hard enough, day after day, that 4,000 cycles over 3,000 actually gets used up rather than sitting unused through the warranty term.
If neither fits
If you're picturing this running a fridge, a space heater, or getting you through an actual multi-day blackout, both units fail that job outright — the engine models both of these losing every scenario from an 8-hour blackout to a weekend camping trip. Look at a unit in the 1,000Wh-plus class instead.
The Bottom Line
The Anker SOLIX C300 and Goal Zero Yeti 300 hold almost the same battery — a gap of nine watt-hours you could round away. What actually separates them is price, weight, and what each spec sheet is willing to tell you: the Anker costs less, weighs less, and publishes a noise rating the Yeti doesn't.
The Yeti's real advantages, more charge cycles and faster solar recharge, are genuine but conditional — they only pay off if you're cycling this thing hard or charging primarily off-grid. Everyone else should keep the money and buy the lighter, cheaper, fully-specced unit: the Anker.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the Goal Zero Yeti 300 worth $110 more than the Anker SOLIX C300?
Only if you'll use what the extra money buys. The Yeti has 1,000 more charge cycles (4,000 against 3,000) and double the solar input (200W against 100W), but both units cost almost the same to own over their lifetime — $0.28 per kWh for the Anker, $0.29 for the Yeti. If you're not cycling the battery hard or recharging primarily by sun, the Anker gets you the same ownership economics for $110 less.
Which one is lighter?
The Anker SOLIX C300, by 4.6 lbs — 9.1 lbs against the Yeti 300's 13.7 lbs. For a unit you're carrying in and out of a tent or a trunk repeatedly, that's a real, felt difference.
Why doesn't Goal Zero publish a noise rating for the Yeti 300?
It's not disclosed anywhere in the spec sheet or marketing, which is the one real transparency gap against the Anker's published 25dBA rating. It doesn't necessarily mean the Yeti is loud, but it does mean you're buying without that piece of information, which the Anker gives you upfront.
Can either of these run a coffee maker or a small appliance?
Barely, and unreliably. The Anker is rated 300W continuous and the Yeti 350W — both well under what a coffee maker or space heater draws on startup, and at least one review recorded the Yeti shutting down after about two minutes trying. Treat both as device chargers, not appliance runners.
Does either unit expand?
No. Both are closed systems — whatever capacity you buy today is the ceiling for the life of the unit, with no expansion battery available for either. Size for the load you'll actually run today and over the next few years, not for a load you might grow into.
