Spec deltas
The Anker SOLIX C800 (768Wh) and Goal Zero Yeti 300 (297Wh) sit in different weight classes. The real question: do your power needs justify the larger unit, or would you be overpaying for capacity that sits unused? The SOLIX C800 has a slight edge, but the margin is close enough that your use case should break the tie.
The SOLIX C800 holds 471Wh more than the Yeti 300 — about 4 hours on a fridge against 2 — a real but modest edge that shows up mainly on longer outages. For camping, tailgating, or keeping devices charged, both have the headroom, so price, weight, and longevity lead the decision instead.
Pick the SOLIX C800 if your primary use is cpap overnight. Go with the Yeti 300 if its specific strengths below line up better with your use. Keep scrolling for the full breakdown. The scenario verdicts below hold a few surprises.
Bench Notes
What each unit does well, where it falls short, and the trade-offs that matter.
Anker SOLIX C800
The 1,200W inverter handles most daily devices like laptops, blenders, and TVs, but will struggle with heating elements that require over 1500W. At only 23.8 lbs, it is exceptionally portable. You can easily carry it one-handed to a campsite or tailgating party.
Strengths
- +Larger battery capacity
- +Higher AC output
- +Faster solar charging
Trade-offs
- –Significantly heavier (+10.1 lbs), making it harder to move.
- –Shorter-lived battery — rated for 3,000 charge cycles vs the Yeti 300's 4,000, so it wears out sooner.
Goal Zero Yeti 300
At 350W, this unit is strictly for personal electronics (phones, laptops) and small CPAP machines. Do not expect to run kitchen appliances. At only 13.7 lbs, it is exceptionally portable. You can easily carry it one-handed to a campsite or tailgating party.
Strengths
- +Lighter by 10.1 lb
- +Rated for 4,000 charge cycles — much longer battery lifespan
Trade-offs
- –Weaker inverter (-850W) limits appliance compatibility.

We ran the math on seven 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
Neither unit covers this scenario's 2,100Wh: the SOLIX C800 comes up 1,447Wh short (about 31% covered), the Yeti 300 1,848Wh (12%). This is well outside what either unit is for; the right answer here is a larger station, not a choice between these two.

Sleep therapy without interruption — the #1 medical use case
SOLIX C800
The Yeti 300 doesn't finish — 252Wh usable against the 320Wh this needs leaves it 68Wh short, about 79% of the scenario covered. The SOLIX C800 covers it with 333Wh to spare.

Neither unit
Neither unit covers this scenario's 910Wh: the SOLIX C800 comes up 257Wh short (about 72% covered), the Yeti 300 658Wh (28%). Treat this as partial cover — enough for the essentials in it, not the whole list.

Tailgate Party
Game day power for the crew
Neither unit
The Yeti 300 can start the 400W peak but not hold it — 600W of surge gets it going, then the 350W continuous rating takes over, so capacity never gets a say. This is the wrong size of unit for the job rather than a close call. The SOLIX C800 doesn't have the energy either — 653Wh usable against 670Wh, 17Wh short — so neither route works.

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 C800 barely notices it. For this job the SOLIX C800's extra capacity is dead weight, not headroom; at 13.7 lbs the Yeti 300 is the one you'll be glad you brought.

Conclusion
July 10, 2026
Verdict withdrawn: the SOLIX C800 is no longer sold
We picked the SOLIX C800, but it's been discontinued (Anker now points buyers to the SOLIX C800X). The Yeti 300 is still on sale, but that alone doesn't make it our pick. The comparison below is still accurate if you own either one.

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 C800 rates 4.1/5 (47th percentile of 20 Compact-class units), and Yeti 300 rates 3.7/5 (22nd percentile of 24 Personal-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.
SOLIX C800: 45dB Published
45dB is about as loud as a running refrigerator. It is Anker's own rating rather than a reading on a shared bench — makers differ on whether they quote a best case or a figure under load, so treat it as a starting point rather than what you would hear at a bedside. For most people, fan noise around 45dB and up is where sleep starts to suffer.
Surge Power: Ratio and Ceiling Disagree
The Yeti 300 holds the higher surge-to-continuous ratio (1.7× vs 1.3×), but the SOLIX C800 holds the higher absolute surge ceiling — 1,600W against 600W. These measure different things. The ratio says how much headroom an inverter keeps above its own rating; the ceiling says how big a startup spike it can actually swallow. A motor draws a number of watts at switch-on, not a multiple of someone else's rating, so on raw starting ability the SOLIX C800 is the stronger unit here — while the Yeti 300 is the one running further below its own limit at steady state.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here.
Battery Lifespan in Real Years
The Yeti 300 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 297Wh on the Yeti 300 and 768Wh on the SOLIX C800, so count lifetime energy — roughly 1,188 kWh against 2,304 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 300: Noise Level Not Disclosed
The SOLIX C800 publishes its noise level (45dB); 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 C800's 45dB 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.

Analyst note
The SOLIX C800 is no longer sold, so there is no price to work its cost per kWh from, and this comparison doesn't quote one. On what you can actually buy today, the Yeti 300 works out at $0.29/kWh over its rated life. If you already own the SOLIX C800, the hardware comparison still holds: over its rated life the SOLIX C800 delivers about 2,304 kWh and the Yeti 300 about 1,188 kWh. One caution on the lifespan row: the Yeti 300 takes longer to reach its cycle rating, but a cycle moves a different amount of energy on each unit — the SOLIX C800 still delivers more over its shorter horizon. Years measure wear, not usefulness.
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 — 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
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.
Growth path

FIXED CAPACITYFixed at 768Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.
Accepts up to 300W of solar. Limited to a single portable panel.
Adequate ports for most setups, but heavy users may want a power strip.

Analyst note
Growth only counts if you can still buy in, and the SOLIX C800 is no longer sold (Anker points owners to the SOLIX C800X). That leaves the Yeti 300: it is sealed at 297Wh, so buy the size that covers you now. The SOLIX C800's fixed 768Wh still matters if you already own one, but it isn't a reason to pick it over the Yeti 300.
The Bottom Line
The full picture comes down to this. The SOLIX C800 edges ahead on our overall analysis, but the margin is narrow enough that your specific use case should drive the decision. Review the scenario verdicts above — if the Yeti 300 wins in the scenarios that match your life, it's the right choice regardless of aggregate scores.
If neither the SOLIX C800 nor the Yeti 300 feels like the right fit, your power needs probably sit outside what these two target. If you're planning whole-home backup or running power-hungry appliances (electric heaters, window AC), you'll want a larger system in the 3,000–5,000Wh range with expansion battery support. Prices on portable power stations fluctuate frequently. Both Anker and Goal Zero discount regularly, so check the current price before committing. Prime Day and Black Friday pricing typically drops 20-30%.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Can I actually carry the SOLIX C800, or is the Yeti 300 the only portable option?
The Yeti 300 at 13.7 lbs is genuinely grab-and-go. Toss it in a backpack, carry it one-handed to a picnic, take it on a boat. The SOLIX C800 at 23.8 lbs is a different story. It's like carrying a large suitcase full of books. If you're setting up and breaking down camp frequently, this weight difference will exhaust you by day two.
"4,000 vs 3,000 cycles" — what does that actually mean for me?
In real years: the Yeti 300 (4,000 cycles) lasts 11.0 years at daily use, 38 years at weekend use (twice a week), or 167 years at twice-monthly camping trips. The SOLIX C800 (3,000 cycles): 8.2 years daily, 29 years weekends, or 125 years twice-monthly. What most people miss: hitting the cycle limit doesn't kill your battery. Capacity drops to about 80%. Your 297Wh unit becomes a ~238Wh unit. Still very usable. For weekend users, both batteries will outlast the warranty by years.
Is Anker or Goal Zero more reliable for long-term ownership?
Both brands have strengths and trade-offs. Anker: 5-year warranty standard on portable stations, 10-year on home energy systems. Historically very reliable, though some recent firmware updates have altered product functionality without notice or rollback option. Goal Zero: 5 years on LFP models, 2 years on older NMC models. Battery must be charged within 7 days of purchase and every 6 months to maintain warranty (strict). Product reliability concerns have increased — repeat "Battery Fault" errors reported even on newer Yeti Pro 4000. One piece of advice from the power station community: regardless of brand, buy from Costco or Amazon. Their return policies provide a safety net that manufacturer warranties alone can't match, especially for a product you'll rely on in emergencies. Both brands use LFP (lithium iron phosphate) batteries in their current lineup, the most proven chemistry for longevity and safety.
Bottom line: should I buy the SOLIX C800 or the Yeti 300?
We'd have said the SOLIX C800, but it is no longer sold. The Yeti 300 is still on sale, but that alone doesn't make it our pick. The comparison on this page is still accurate if you own either one.
