Spec deltas
Both carry the Anker name, but they're built for different buyers. The SOLIX C300 DC (288Wh, 300W) and the SOLIX F2600 (2,560Wh, 2,400W) come from different product lines with different engineering priorities and a $900 price gap. The SOLIX F2600 has a slight edge, but the margin is close enough that your use case should break the tie.
What the spec gap means in practice: the SOLIX F2600's 2,400W inverter has the headroom for a window AC, a full-size fridge, and power tools. The SOLIX C300 DC's 300W inverter can't run the heaviest of those — a window AC or a high-surge power tool needs more than it can hold, and it publishes no surge headroom above that rating. On stamina, the SOLIX F2600 keeps a fridge alive for roughly 15 hours vs the SOLIX C300 DC's 2 hours. The cost? Portability. At 70.5 lbs, the SOLIX F2600 is heavy enough to make you think twice about moving it. The SOLIX C300 DC at 6.2 lbs is something one person can actually carry.
Pick the SOLIX F2600 if your primary use is weekend camping or 8-hour blackout. Go with the SOLIX C300 DC if its specific strengths below line up better with your use. Most buyers stop at the sticker price and miss this: over a full lifespan the SOLIX F2600 works out to about $0.14/kWh against the SOLIX C300 DC's $0.23, a gap that compounds in the SOLIX F2600'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 C300 DC
At 300W, this unit is strictly for personal electronics (phones, laptops) and small CPAP machines. Do not expect to run kitchen appliances. At only 6.2 lbs, it is exceptionally portable. You can easily carry it one-handed to a campsite or tailgating party.
Strengths
- +Costs $900 less
- +Lighter by 64.3 lb
Trade-offs
- –Weaker inverter (-2,100W) limits appliance compatibility.
- –Sealed capacity — the SOLIX F2600 can add batteries to grow past 288Wh; this one can't.
Anker SOLIX F2600
With a massive 2,400W output (and 2,800W surge), the SOLIX F2600 can run high-wattage appliances like space heaters, hair dryers, and electric grills without tripping. Weighing in at 70.5 lbs, this is not a unit you want to carry far. It's best suited as a stationary backup or RV companion. A standout feature is the value proposition: at roughly $0.43 per watt-hour, it's one of the most cost-effective options on the market.
Strengths
- +Larger battery capacity
- +Higher AC output
- +Longer warranty
- +Faster solar charging
Trade-offs
- –Substantially more expensive (+$900) than the SOLIX C300 DC.
- –Significantly heavier (+64.3 lbs), making it harder to move.

Conclusion
July 10, 2026
Verdict: the SOLIX F2600, on Power Score margin
These two units are closely matched on individual specs, but our Power Score analysis gives the SOLIX F2600 the edge with a composite score of 4,013 vs 1,610. One class note: the SOLIX C300 DC is DC-only — its output figure is a USB/12V port total, not an inverter rating, and nothing with a wall plug runs on it.
Overall score margin: 1,610 vs 4,013 — note the SOLIX C300 DC is DC-only, so its output enters the score as a USB/12V port total, not an inverter rating (−149.3%)

Hidden gotchas and advantages we spotted that you won't find on the product page.
SOLIX F2600: 70.5 lbs Is a Commitment
At 70.5 lbs, this is manageable but not fun to move. That's heavier than a large checked suitcase. How much it costs you depends on whether it rolls — wheels and a telescoping handle change the job completely at this weight, and our spec record doesn't track them, so look at the product photos before you plan on carrying it from the car.
SOLIX C300 DC: No AC Outlets At All
The SOLIX C300 DC's 300W is a DC port total — USB and 12V — not an inverter rating. Anything with a wall plug (a fridge, a TV, a coffee maker, most fans and lamps) never plugs in, at any wattage. That's the design, not a defect: it buys weight, silence, and efficiency for phone, laptop, camera, and 12V-CPAP loads. The SOLIX F2600 carries a real inverter behind 4 AC outlets, so it plays in both worlds. Decide which side of that line your gear lives on before weighing anything else on this page.
SOLIX C300 DC: Fixed Capacity
The SOLIX C300 DC is sealed at 288Wh — fine if that covers you, but it's the ceiling. By contrast the SOLIX F2600 can add expansion batteries, though the first thing it has over the SOLIX C300 DC is its own 2,560Wh base — expansion is the step after that, for the buyer who would outgrow 2,560Wh as well.
Only the SOLIX F2600 Lists a UPS Mode
The SOLIX F2600 can sit between the wall and your gear and hand it to battery when the grid drops — rated ≤20ms — fine on paper for routers and most electronics; the fussiest PC power supplies sit right at this line. Worth it for a router, a desktop PC, or a CPAP. The SOLIX C300 DC'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 3
The SOLIX F2600 is covered for 5 years against the SOLIX C300 DC's 3 years. The cheaper SOLIX C300 DC does buy more warranty per dollar (15 years per $1,000 against 4.5), but that is a statement about price, not about coverage — if a fault appears in year 4, only one of these is still covered. An underrated factor if you're keeping this unit for years.

Analyst note
The SOLIX C300 DC is cheaper to buy, but the SOLIX F2600 is cheaper to own. At $0.14/kWh over its lifetime vs $0.23/kWh, the SOLIX F2600'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 3,000-cycle rating, so the lifetime rows are sticker price and capacity in disguise — the wear horizon is identical and decides nothing here.

Analyst note
The SOLIX C300 DC is sealed at 288Wh, which is fine if that covers you. The SOLIX F2600 starts at 2,560Wh and can grow beyond it with Anker expansion batteries — real headroom the SOLIX C300 DC doesn't have if your needs climb toward partial-home backup.
The Bottom Line
The full picture comes down to this. The SOLIX F2600 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 SOLIX C300 DC wins in the scenarios that match your life, it's the right choice regardless of aggregate scores.
If neither the SOLIX C300 DC nor the SOLIX F2600 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 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 SOLIX F2600 worth $900 more than the SOLIX C300 DC?
The short answer: yes, if you'll actually use the extra capability. The SOLIX F2600 costs $900 more, but that premium buys you 2,272Wh more battery capacity (that's 13 extra hours of running a mini-fridge); 2,100W higher AC output (opening the door to more demanding appliances); 900W faster solar charging for quicker off-grid recovery. On a cost-per-watt-hour basis, you're paying $0.43/Wh vs $0.69/Wh. Factor in cycle life and the math flips: the SOLIX F2600 costs $0.14/kWh over its lifetime vs $0.23/kWh. The "expensive" unit is actually cheaper to own. For regular use, we'd pay the premium.
How does the 2,272Wh capacity difference actually affect daily use?
The SOLIX F2600's 2,560Wh battery keeps a mini-fridge running for roughly 15 hours vs the SOLIX C300 DC's 2 hours. Where it really matters: during an 8-hour blackout running your fridge, router, lights, AND charging your phone simultaneously (about 1,645Wh total), the SOLIX F2600 handles it while the SOLIX C300 DC runs dry. What specs don't mention: runtime drops 20-30% in cold weather (below 32°F/0°C) as battery chemistry slows down. The SOLIX F2600's extra capacity provides a critical cold-weather buffer. For occasional phone and laptop charging, both are overkill. This gap only matters for sustained, multi-appliance use.
Can I actually carry the SOLIX F2600, or is the SOLIX C300 DC the only portable option?
The SOLIX C300 DC at 6.2 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 F2600 at 70.5 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.
How fast can each unit recharge from solar panels in real conditions?
On paper, the SOLIX F2600 accepts 1,000W vs the SOLIX C300 DC's 100W 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 3.7 hours for the SOLIX F2600 and 4.1 hours for the SOLIX C300 DC. That gap widens on cloudy days, when the SOLIX F2600'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 SOLIX F2600's advantage is substantial.
Can I use the SOLIX F2600 as a home UPS to protect my electronics during blackouts?
Yes. The SOLIX F2600 has UPS mode with true 0ms switchover (double-conversion). Even hospital-grade equipment won't notice. Plug in your desktop PC, router, NAS, or CPAP machine and it switches to battery seamlessly when the grid drops. The SOLIX C300 DC does not have this feature. Without UPS, a blackout means: your PC reboots (potentially corrupting unsaved work), your NAS may corrupt its drive array, your CPAP alarms and wakes you up, and your security cameras go dark until you manually switch them over. If always-on power protection matters, this is a dealbreaker advantage for the SOLIX F2600.
What if I need more capacity than the SOLIX C300 DC's 288Wh later?
The SOLIX C300 DC is sealed at 288Wh, so if you expect your needs to climb, the SOLIX F2600 is the more future-proof pick: it starts at 2,560Wh and adds Anker-compatible batteries without replacing the base unit. That said, "not expandable" isn't a flaw on its own — if 288Wh comfortably covers your loads, the SOLIX C300 DC is a complete unit, not a downgrade.
Bottom line: should I buy the SOLIX C300 DC or the SOLIX F2600?
We'd pay the premium for the SOLIX F2600. Yes, it costs more. The capability jump is real: you're stepping into a tier that handles appliances the base model can't start. The SOLIX C300 DC is still solid if budget is the priority, but the SOLIX F2600 will leave you less likely to wish you'd "gone bigger" six months from now. That regret costs more than the price difference.
