Spec deltas
The Anker SOLIX C1000 and Goal Zero Yeti 1500 (6th Gen) compete for the same spot. Similar LiFePO4 capacity, similar price range, different brands behind them. In this matchup, ecosystem, app quality, and warranty reputation matter as much as raw specs. The SOLIX C1000 has a slight edge, but the margin is close enough that your use case should break the tie.
The Yeti 1500 (6th Gen) holds 449Wh more than the SOLIX C1000 — about 9 hours on a fridge against 6 — 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 C1000 if you want the unit that wins the head-to-head on balance. Go with the Yeti 1500 (6th Gen) if you primarily need it for remote workday or tailgate party. Most buyers stop at the sticker price and miss this: over a full lifespan the SOLIX C1000 works out to about $0.16/kWh against the Yeti 1500 (6th Gen)'s $0.25, a gap that compounds in the SOLIX C1000's favor the more you cycle it. 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 C1000
The 1,800W inverter handles most daily devices like laptops, blenders, and TVs, but will struggle with heating elements that require over 1500W. A standout feature is the value proposition: at roughly $0.47 per watt-hour, it's one of the most cost-effective options on the market.
Strengths
- +Costs $1,000 less
- +Lighter by 24.4 lb
Trade-offs
- –Shorter-lived battery — rated for 3,000 charge cycles vs the Yeti 1500 (6th Gen)'s 4,000, so it wears out sooner.
Goal Zero Yeti 1500 (6th Gen)
The 2,000W inverter handles most daily devices like laptops, blenders, and TVs, but will struggle with heating elements that require over 1500W. Weighing in at 52.8 lbs, this is not a unit you want to carry far. It's best suited as a stationary backup or RV companion.
Strengths
- +Larger battery capacity
- +Higher AC output
- +Faster solar charging
- +Rated for 4,000 charge cycles — much longer battery lifespan
Trade-offs
- –Substantially more expensive (+$1,000) than the SOLIX C1000.
- –Significantly heavier (+24.4 lbs), making it harder to move.

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
Neither unit
Neither unit covers this scenario's 2,100Wh: the SOLIX C1000 comes up 1,202Wh short (about 43% covered), the Yeti 1500 (6th Gen) 821Wh (61%). Treat this as partial cover — enough for the essentials in it, not the whole list.

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 SOLIX C1000 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.

SCN-04 · 8 hours · needs 910Wh
Remote Workday
Full work day off-grid without power anxiety
Yeti 1500 (6th Gen)
The SOLIX C1000 comes up just short — it needs 910Wh and has 898Wh usable, a 12Wh gap (its nameplate 1,056Wh actually clears this — the flat 15% conversion allowance is what tips it under). Trim that much — one small appliance's worth across the day — and it finishes. The Yeti 1500 (6th Gen) covers it outright with 369Wh to spare.

Tailgate Party
Game day power for the crew
Yeti 1500 (6th Gen)
Both handle game day; the Yeti 1500 (6th Gen) keeps more in reserve (52% used vs 75%). Tailgating is a light load, though, so the number you'll feel is weight: 28.4 lbs for the SOLIX C1000 against 52.8 lbs for the Yeti 1500 (6th Gen), from the trunk to the setup spot.

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 C1000 rates 4.6/5 (78th percentile of 24 Everyday-class units), and Yeti 1500 (6th Gen) rates 3.4/5 (4th percentile of 24 Everyday-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.
Yeti 1500 (6th Gen): Fixed Capacity
The Yeti 1500 (6th Gen) is sealed at 1,505Wh — a complete unit, and already larger than the SOLIX C1000's 1,056Wh. By contrast the SOLIX C1000 can add expansion batteries, but that only pulls ahead if you'd grow past 1,505Wh.
Surge Power: Inverter Quality Indicator
The Yeti 1500 (6th Gen) has a 1.8× surge-to-continuous ratio vs the SOLIX C1000's 1.3×, and the higher absolute ceiling with it — 3,600W against 2,400W. A higher ratio (≥2×) means the inverter absorbs motor startup surges better, which matters for fridges, AC compressors, and power tools that briefly draw 2-3× their rated wattage. With both measures pointing the same way, the SOLIX C1000 is the one more likely to trip when starting these appliances.
UPS Switchover: ≤15ms vs ≤20ms
Both list a UPS mode, at different rated speeds. The Yeti 1500 (6th Gen) is rated ≤15ms — fine on paper for routers and most electronics; the fussiest PC power supplies sit right at this line. The SOLIX C1000 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 C1000 works out at 10 years of cover per $1,000 spent against the Yeti 1500 (6th Gen)'s 3.3, but that spread is the price gap, not the terms.
Battery Lifespan in Real Years
The Yeti 1500 (6th Gen) 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 1,505Wh on the Yeti 1500 (6th Gen) and 1,056Wh on the SOLIX C1000, so count lifetime energy — roughly 6,021 kWh against 3,168 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 C1000.

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 still widely sold, 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.

Realistic full solar rechargeat 70% of rated panel output — see methodology
Analyst note
Don't read the SOLIX C1000's expandability as a straight win here: it starts at 1,056Wh, below the Yeti 1500 (6th Gen)'s 1,505Wh, so a first expansion battery largely buys back capacity the Yeti 1500 (6th Gen) already includes. It only pulls ahead if you'd grow past 1,505Wh — short of that, the Yeti 1500 (6th Gen)'s larger fixed capacity is the simpler value.
The Bottom Line
The full picture comes down to this. The SOLIX C1000 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 1500 (6th Gen) wins in the scenarios that match your life, it's the right choice regardless of aggregate scores.
If neither the SOLIX C1000 nor the Yeti 1500 (6th Gen) feels like the right fit, your power needs probably sit outside what these two target. Use our comparison tool above to explore alternatives that better match your specific wattage and runtime requirements. 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.
Is the Yeti 1500 (6th Gen) worth $1,000 more than the SOLIX C1000?
The short answer: yes, if you'll actually use the extra capability. The Yeti 1500 (6th Gen) costs $1,000 more, but that premium buys you 449.3Wh more battery capacity (that's 3 extra hours of running a mini-fridge); 200W higher AC output (opening the door to more demanding appliances); a longer-lasting battery rated for 4,000 cycles — that's 11 years at daily use; 300W faster solar charging for quicker off-grid recovery. On a cost-per-watt-hour basis, you're paying $1.00/Wh vs $0.47/Wh. For regular use, we'd pay the premium.
Can I actually carry the Yeti 1500 (6th Gen), or is the SOLIX C1000 the only portable option?
At 28.4 lbs, the SOLIX C1000 is manageable for one person over short distances: parking lot to campsite, trunk to tailgate. The Yeti 1500 (6th Gen) at 52.8 lbs? You'll want a buddy, a wagon, or wheels. For reference, 52.8 lbs is about the weight of a bag of concrete. If your use case involves any carrying, the SOLIX C1000 wins decisively.
How fast can each unit recharge from solar panels in real conditions?
On paper, the Yeti 1500 (6th Gen) accepts 900W vs the SOLIX C1000's 600W of solar input. What the spec sheet won't tell you: solar panels typically deliver only 60-80% of their rated output due to panel angle, cloud cover, and temperature. In realistic conditions, expect full recharge in about 2.4 hours for the Yeti 1500 (6th Gen) and 2.5 hours for the SOLIX C1000. That gap widens on cloudy days, when the Yeti 1500 (6th Gen)'s higher input ceiling captures more of whatever sunlight is available. One more thing: summer gives you ~7 productive solar hours per day. Winter drops to ~4. If solar is your primary recharge method, the Yeti 1500 (6th Gen)'s advantage is substantial.
"4,000 vs 3,000 cycles" — what does that actually mean for me?
In real years: the Yeti 1500 (6th Gen) (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 C1000 (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 1,505.3Wh unit becomes a ~1,204Wh unit. Still very usable. For weekend users, both batteries will outlast the warranty by years.
Does the SOLIX C1000's expandability make it the safer long-term buy?
Not necessarily. The SOLIX C1000 can add Anker batteries, but it starts at 1,056Wh — below the Yeti 1500 (6th Gen)'s sealed 1,505.3Wh. A first expansion battery mostly buys back capacity the Yeti 1500 (6th Gen) already gives you out of the box; expandability only pulls ahead if you expect to grow past 1,505.3Wh. If you don't, the Yeti 1500 (6th Gen)'s larger fixed capacity is the simpler, complete package — not a dead end, just already the bigger battery.
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 C1000 or the Yeti 1500 (6th Gen)?
We'd buy the SOLIX C1000. Strong value at a lower price, and for most real-world use cases the spec gaps don't translate to meaningful capability gaps. The Yeti 1500 (6th Gen) makes sense only if you specifically need its higher capacity for demanding sustained loads like full-home backup or commercial use.
