Spec deltas
Two sizes from Anker's SOLIX C lineup: SOLIX C200 DC at 192Wh, SOLIX C300 at 288Wh. The $120 gap between them buys a fundamentally different tool. One you carry. One you place and leave. Neither unit pulls ahead clearly. That means your specific use case decides this one.
On stored energy these two are effectively matched — 288Wh vs 192Wh, both good for roughly 2 hours on a fridge — so runtime isn't what decides this. The call comes down to a $120 price gap — plus cycle life and warranty, covered below.
Both handle weekend camping, tailgating, and emergency preparedness. Your call is whether saving $120 (SOLIX C200 DC) matters more than the SOLIX C300's specific advantages. Most buyers stop at the sticker price and miss this: over a full lifespan the SOLIX C200 DC works out to about $0.21/kWh against the SOLIX C300's $0.28, a gap that compounds in the SOLIX C200 DC'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.

These reveal the real limits¹ Runtime = (capacity × 0.85) ÷ appliance watts. Within each group, all bars share one time scale (the group's longest runtime), so lengths are comparable across appliances; identical runtimes collapse into a single blue/orange bar. Actual runtime varies with battery age, temperature, and simultaneous loads — see methodology.
Conclusion
July 10, 2026
Verdict: evenly matched
These two units are evenly matched. The SOLIX C200 DC is lighter by 4.9 lbs, while the price difference is only $120. Your choice comes down to brand preference mostly.

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 C200 DC rates 4.3/5 (57th percentile of 22 Personal-class units), and SOLIX C300 rates 4.8/5 (86th percentile of 22 Personal-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
Only the SOLIX C300 Has UPS Protection
The SOLIX C300 can act as an uninterruptible power supply. Plug your PC, router, or CPAP into it and it switches to battery seamlessly during an outage. The SOLIX C200 DC doesn't have this feature, so connected devices will experience a power interruption.
Warranty Value Comparison
The SOLIX C200 DC gives you 25 years of warranty per $1,000 spent, vs the SOLIX C300's 20.8 years. That's 1.2× more coverage per dollar. An underrated factor if you're keeping this unit for years.
SOLIX C200 DC: Noise Level Not Disclosed
The SOLIX C300 publishes its noise level (25dB), but the SOLIX C200 DC doesn't. Brands that don't disclose noise specs often have louder units. If noise matters to you (CPAP users, apartment dwellers), this is worth investigating before buying.

Analyst note
The SOLIX C200 DC wins on both sticker price and long-term value. At $0.21/kWh over its lifetime, it's meaningfully cheaper to own. Clear value winner.
Growth path
SOLIX C200 DC
FIXED CAPACITYFixed at 192Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.
Accepts up to 100W of solar. Limited to a single portable panel.
Limited ports. You'll likely need a power strip or splitter.
SOLIX C300
FIXED CAPACITYFixed at 288Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.
Accepts up to 100W of solar. Limited to a single portable panel.
Adequate ports for most setups, but heavy users may want a power strip.
Realistic full solar rechargeat 70% of rated panel output — see methodology
Analyst note
Neither expands, and that's no knock on either — each is a complete unit at a fixed size. Buy the capacity that covers your needs now (the SOLIX C300 gives you the larger ceiling); you can't add to either later.
The Bottom Line
These two LiFePO4 portable power stations are genuinely close. After comparing capacity, output, portability, price, and real-world runtime, neither has a decisive advantage. If budget is the deciding factor, the SOLIX C200 DC saves you $120. If you need the extra 96Wh of capacity, the SOLIX C300 justifies the spend.
If neither the SOLIX C200 DC nor the SOLIX C300 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 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 C300 worth $120 more than the SOLIX C200 DC?
The short answer: yes, if you'll actually use the extra capability. The SOLIX C300 costs $120 more, but that premium buys you 96Wh more battery capacity (that's 1 extra hours of running a mini-fridge); 100W higher AC output (opening the door to more demanding appliances). On a cost-per-watt-hour basis, you're paying $0.83/Wh vs $0.62/Wh. For regular use, we'd pay the premium.
Can I use the SOLIX C300 as a home UPS to protect my electronics during blackouts?
Yes. The SOLIX C300 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 C200 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 C300.
