Spec deltas
The Anker SOLIX C300 DC (288Wh) and Jackery HomePower 3600 Pro Max (3,584Wh) 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 HomePower 3600 Pro Max 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 HomePower 3600 Pro Max's 4,000W inverter has the headroom for a window AC, a full-size fridge, and power tools. The SOLIX C300 DC's 300W inverter can't start the heaviest of those — a window AC or a high-surge power tool will trip it. On stamina, the HomePower 3600 Pro Max keeps a fridge alive for roughly 20 hours vs the SOLIX C300 DC's 2 hours. The cost? Portability. At 73.9 lbs, the HomePower 3600 Pro Max 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 HomePower 3600 Pro Max 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 HomePower 3600 Pro Max works out to about $0.08/kWh against the SOLIX C300 DC's $0.23, a gap that compounds in the HomePower 3600 Pro Max'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 $1,599 less
- +Lighter by 67.7 lb
- +Faster solar charging
Trade-offs
- –Weaker inverter (-3,700W) limits appliance compatibility.
- –Sealed capacity — the HomePower 3600 Pro Max can add batteries to grow past 288Wh; this one can't.
- –Shorter-lived battery — rated for 3,000 charge cycles vs the HomePower 3600 Pro Max's 6,000, so it wears out sooner.
Jackery HomePower 3600 Pro Max
With a massive 4,000W output (and 8,000,240W surge), the HomePower 3600 Pro Max can run high-wattage appliances like space heaters, hair dryers, and electric grills without tripping. Weighing in at 73.9 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 $0.50 per watt-hour, it's one of the most cost-effective options on the market.
Strengths
- +Larger battery capacity
- +Higher AC output
- +Longer warranty
- +Rated for 6,000 charge cycles — much longer battery lifespan
Trade-offs
- –Substantially more expensive (+$1,599) than the SOLIX C300 DC.
- –Significantly heavier (+67.7 lbs), making it harder to move.

HomePower 3600 Pro Max: 73.9 lbs Is a Commitment
At 73.9 lbs, this is manageable but not fun to carry. That's heavier than a large checked suitcase. Moving it from your car to a campsite requires some effort and flat terrain.
SOLIX C300 DC: Fixed Capacity
The SOLIX C300 DC is sealed at 288Wh — fine if that covers you, but it's the ceiling. The HomePower 3600 Pro Max starts at 3,584Wh and can add expansion batteries, so if your needs may climb toward partial-home backup, it has room to grow the SOLIX C300 DC doesn't.
Only the HomePower 3600 Pro Max Has UPS Protection
The HomePower 3600 Pro Max 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 C300 DC doesn't have this feature, so connected devices will experience a power interruption.
Warranty Value Comparison
The SOLIX C300 DC gives you 15 years of warranty per $1,000 spent, vs the HomePower 3600 Pro Max's 2.8 years. That's 5.4× more coverage per dollar. An underrated factor if you're keeping this unit for years.
Battery Lifespan in Real Years
The HomePower 3600 Pro Max is rated for 6,000 cycles vs 3,000. In real life: at daily use, that's 16.4 vs 8.2 years. At weekend use (twice a week), it's 58 vs 29 years. After hitting the cycle limit, the battery doesn't die. It drops to ~80% original capacity, which is still very usable.
SOLIX C300 DC: Noise Level Not Disclosed
The HomePower 3600 Pro Max publishes its noise level (30dB), but the SOLIX C300 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.

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.
Jackery
Ecosystem
12-15+ models across Explorer (portable) and HomePower (home backup) series, plus SolarSaga panel ecosystem and innovative form factors
Support
US-based support but widely criticized. Reddit reports describe slow/dismissive responses, scripted AI agents, strict receipt requirements for warranty claims, and refurbished replacements for clearly defective units. Strongly recommended: buy from Costco or Amazon for return protection.
Community
Smallest community of the major brands — Reddit r/Jackery has ~2,000 members. YouTube presence is solid due to brand recognition.
App experience
Rated 2.3-3.3/5 iOS and Android — the weakest app experience of the major brands. Multiple confusing apps (Jackery app vs Jackery Home) and mandatory login even offline.
Unique strength
Highest brand recognition and widest retail distribution (Costco, Home Depot, Best Buy, Amazon). The "Toyota" of power stations — dependable, proven, wide availability. Innovative form factors like the Solar Gazebo and Solar Mars Bot.
Worth knowing
A couple of older models still ship NMC chemistry with a shorter rated lifespan, so check the cycle rating on the specific unit — though most of the current line has moved to LFP. Generally perceived as overpriced for the specs offered compared to newer competitors. App experience is significantly behind rivals.
Analyst note
Anker and Jackery are close competitors. Both have established support channels and growing ecosystems. Compare their specific warranty terms and community size for your peace of mind.
Growth path
SOLIX C300 DC
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.
HomePower 3600 Pro Max
EXPANDABLESupports Jackery expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 3,584Wh.
No solar input available.
Limited ports. You'll likely need a power strip or splitter.
Expansion batteries are Jackery-specific. You're investing in the Jackery ecosystem.
Analyst note
The SOLIX C300 DC is sealed at 288Wh, which is fine if that covers you. The HomePower 3600 Pro Max starts at 3,584Wh and can grow beyond it with Jackery 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 HomePower 3600 Pro Max 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 HomePower 3600 Pro Max 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 Jackery 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 HomePower 3600 Pro Max worth $1,599 more than the SOLIX C300 DC?
The short answer: yes, if you'll actually use the extra capability. The HomePower 3600 Pro Max costs $1,599 more, but that premium buys you 3,296Wh more battery capacity (that's 19 extra hours of running a mini-fridge); 3,700W higher AC output (opening the door to more demanding appliances); a longer-lasting battery rated for 6,000 cycles — that's 16 years at daily use. On a cost-per-watt-hour basis, you're paying $0.50/Wh vs $0.69/Wh. Factor in cycle life and the math flips: the HomePower 3600 Pro Max costs $0.08/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 3,296Wh capacity difference actually affect daily use?
The HomePower 3600 Pro Max's 3,584Wh battery keeps a mini-fridge running for roughly 20 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 HomePower 3600 Pro Max 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 HomePower 3600 Pro Max'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 HomePower 3600 Pro Max, 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 HomePower 3600 Pro Max at 73.9 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.
"6,000 vs 3,000 cycles" — what does that actually mean for me?
In real years: the HomePower 3600 Pro Max (6,000 cycles) lasts 16.4 years at daily use, 58 years at weekend use (twice a week), or 250 years at twice-monthly camping trips. The SOLIX C300 DC (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 3,584Wh unit becomes a ~2,867Wh unit. Still very usable. For weekend users, both batteries will outlast the warranty by years.
Can I use the HomePower 3600 Pro Max as a home UPS to protect my electronics during blackouts?
Yes. The HomePower 3600 Pro Max 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 HomePower 3600 Pro Max.
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 HomePower 3600 Pro Max is the more future-proof pick: it starts at 3,584Wh and adds Jackery-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.
Is Anker or Jackery 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. Jackery: 2-5 years depending on model (premium models like 5000 Plus get 5 years, budget models get 2 years). Registration required for extension. Claims process can be frustrating. 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 C300 DC or the HomePower 3600 Pro Max?
We'd pay the premium for the HomePower 3600 Pro Max. 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 HomePower 3600 Pro Max will leave you less likely to wish you'd "gone bigger" six months from now. That regret costs more than the price difference.
