Spec deltas
The Anker SOLIX C300 DC has no AC inverter. Its surge rating is 0W, and the 300W on the spec line is the total its DC ports can push, not a wall socket. The Jackery HomePower 3000 runs 3,600W continuous with 7,200W of surge behind 3,072Wh. One of these is a very good 6-pound battery for a laptop bag. The other is a box that keeps a house lit.
So the scenarios below sweep to the Jackery, five of six, and the sixth is a loss for both. That is not a rout. Most of those losses are settled by energy before outlets even come up: one night of CPAP asks for 320Wh and the C300 DC holds 245Wh after derating, so it quits before your alarm. The rest it could theoretically feed, it still cannot serve, because there is nowhere to plug them in.
Which leaves a useful question instead of a fake one. Buy the C300 DC if everything you own charges over USB-C or 12V, in which case it is better at that job than the $1,399 unit is: 140W of USB-C against 100W. Buy the HomePower 3000 if you need outlets. If you need outlets and don't need 3,072Wh of them, buy neither of these and shop the middle of the category.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
Reviewers draw the same line: it is built for charging devices, not running appliancesA4. So the C300 DC doesn't lose the AC scenarios on this page, it declines them. Any row that shows it meeting a household peak is quietly comparing DC watts to an AC load, and the comparison has no meaning.
SOLIX C300 DC surge rating: 0W, with no AC inverterA1SOLIX C300 DC outputs: USB-C, USB-A and a 12V car socketA2HomePower 3000: 3,600W continuous, 7,200W surge
Why it mattersIf one single thing you want to power ends in a two-prong plug, the C300 DC is out before price, weight or capacity gets a vote.
solar input
That inverts the assumption that small means quick to top up. On the 4,685Wh van day that beats both units, the Jackery's 1,400W ceiling is the only thing here that can claw back a full charge inside a couple of hours. The C300 DC's 100W ceiling means one overcast morning costs it most of a day it barely had to begin with.
SOLIX C300 DC: 288Wh, 100W maximum solar inputHomePower 3000: 3,072Wh, 1,400W maximum solar inputVan Life Daily needs 4,685Wh, and neither unit covers it
Why it mattersAnyone living off panels should be shopping input watts rather than capacity, and should be looking above both of these.
rated cycles
Nobody should buy the C300 DC on value grounds, because there aren't any. What $200 buys is 6.17 lb and a shape that slides into a laptop bag, which is a perfectly good thing to spend money on. It just isn't cheap energy, and a buyer who thinks they're being frugal has the story backwards.
$200 ÷ 288Wh = $0.69 per watt-hour$1,399 ÷ 3,072Wh = $0.39 per watt-hourRated life: 288Wh × 3,000 cycles = 864 kWh; 3,072Wh × 4,000 cycles = 12,288 kWh
Why it mattersBudget-driven shoppers should notice that the sticker price is the only number on this page that favors the small unit.
The C300 DC also refills through that same port, so the charger already in your bag works in both directionsA2, while the Jackery wants a wall or an array. For a load that is a laptop, a phone and a camera, the small unit is not the budget option. It is the better tool, and the Jackery becomes $1,199 of inverter you never switch on.
SOLIX C300 DC: 140W maximum USB-C outputHomePower 3000: 100W maximum USB-C outputTwo-way USB-C PD 3.1 brings the C300 DC back to 80% in about an hourA2
Why it mattersIf your packing list has no plugs in it, stop comparing and take the C300 DC.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: the HomePower 3000 takes five of the six scenarios and the sixth goes to neither, and the pattern of those losses says more than the tally does.
Five wins for the HomePower 3000 and one loss for both is what a category gap looks like written as a scorecard. Energy alone settles most of it before outlets come up: a 2,100Wh camping weekend would take about nine C300 DCs (2,100 ÷ 245Wh usable), and an eight-hour blackout at 1,645Wh is a 63% dent in the Jackery. Ignore any row here suggesting the C300 DC can meet a household peak draw. Those are DC watts, and there is no outlet behind them.
Van Life Daily is the honest entry. Nobody wins a 4,685Wh day. The Jackery covers 2,611Wh of it, a bit over half, then leans on sun for the rest; the C300 DC would need emptying and refilling nineteen times over. Read a full-time van build as a bigger battery and a bigger array than anything on this page, not as a close call between these two.
Portability & Form Factor
Selected because: 6.17 lb against 59.52 lb is the one axis where the cheap unit is untouchable, and for a lot of buyers it is the only axis that matters.
weight
6.17 lb is a thing you forget is in the bag. 59.52 lb is a squat, a grip check, and a decision about which trip it's coming on, even though one person can manage itB1. In fairness to the Jackery, that weight is remarkable for what's inside it. Reviewers rate it the smallest and lightest 3kWh station going, and its 16.4-inch width fits shelves and closets that turn rivals awayB1.
Light for 3kWh still isn't light. If the unit has to leave the house on foot, through an airport, up to a third-floor walkup, only one of these is going. If it's going to live behind the utility-closet door and come out when the lights do, the weight is a problem you solve once on delivery day and never think about again.
Runtime: Will It Power Your Gear?
Selected because: usable energy is 245Wh against 2,611Wh after the standard 15% derate, and those two numbers settle every load question here before wattage gets involved.
continuous output
Both capacities shrink before you use them. Derating to 85% for conversion losses turns 288Wh into 245Wh and 3,072Wh into 2,611Wh, and those are the figures every load question is actually decided against. What 245Wh looks like in the field: several phone and laptop refills, a fan for hours, a small light setupA3. That is a real day of work for a traveler and nothing at all for a house.
The Jackery's side has been measured rather than modeled. Backup testing has it holding a standard refrigerator for nearly two days and a 55-inch TV for around 30 hoursB4. On USB-C, though, the small unit is the quicker one at 140W against 100W. If the runtime you care about is your laptop's, the $200 bank charges it faster and the $1,399 one simply keeps doing it for longer.
Lifetime Value
Selected because: the $1,399 unit delivers energy at $0.10 per lifetime kWh and the $200 unit at $0.23, which is the reverse of what the price tags imply.
cost / lifetime kWh
$200 buys the more expensive electricity on this page. Across rated life the C300 DC delivers 864 kWh (288Wh × 3,000 cycles) for its purchase price, which is $0.23 a kilowatt-hour. The HomePower 3000 delivers 12,288 kWh (3,072Wh × 4,000 cycles) for $1,399, or a dime. Cycled once a day that's 8.2 years of service against 11.
Ownership cost is not the reason to buy the small one, and the sticker price will try to tell you otherwise. The honest catch cuts the other way as well: both figures assume you actually cycle the thing. A backup unit that sits charged between outages will age out long before it runs out of cycles, so the Jackery's 12,288 kWh is a ceiling it will likely never reach, while the C300 DC, emptied constantly because 288Wh empties fast, might genuinely get there.

Scenario verdicts
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
HomePower 3000
A 2,100Wh weekend fits inside the HomePower's usable stock with room left over, at 80%. The C300 DC would need about nine of itself to match it (2,100 ÷ 245Wh usable), which is the polite way of saying this isn't its weekend. It's a device charger that happens to be along for the trip, not the power supply for one.

SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
HomePower 3000
Eight hours of household load is 1,645Wh and the Jackery gives it up without complaint, 63% of usable. The number that matters more is the 20-millisecond handoff, which means the fridge and the router never learn the grid went away. The C300 DC has no AC output, so a blackout isn't a job it can be assigned.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
HomePower 3000
One night of CPAP is 320Wh, which the HomePower barely registers at 12% of usable, and Jackery publishes 30 dBA for the fan that will be sitting a couple of feet from your head. The C300 DC loses on energy before anything else: 320Wh against 245Wh usable means it stops before the alarm does.
Battery budget usedlower = more headroom
LOAD CPAP Machine 40W×8h
SCN-04 · 8 hours · needs 910Wh
Remote Workday
Full work day off-grid without power anxiety
HomePower 3000
A 910Wh workday is 35% of the Jackery's usable capacity, a non-event. It's also the scenario where the C300 DC comes closest to relevant and still falls short, covering roughly a quarter of the day at 245Wh. If your actual workday is a laptop and a phone rather than 910Wh of draw, though, you were never shopping for this scenario.

Tailgate Party
Game day power for the crew
HomePower 3000
670Wh of tailgate is 26% of the Jackery's usable capacity, and 7,200W of surge means the blender and the griddle can start at the same moment without an argument. This is also the one load here whose peak draw exceeds the C300 DC's 300W ceiling outright, which saves everyone the longer explanation about outlets.

Van Life Daily
A full day of mobile living — the ultimate endurance test
Neither unit
Nobody wins a 4,685Wh day. The HomePower covers 2,611Wh of it, a bit over half, then depends on its 1,400W solar ceiling to put a full charge back inside about two hours of strong sun (3,072 ÷ 1,400). The C300 DC holds 245Wh, so a van day would need it nineteen times over. Full-time van power starts above both of these, in capacity and in array.

Phones and a speaker at the park, beach, or campsite — the small-unit job description
Either unit
This row is here for the SOLIX C300 DC's class of job: phones and a speaker, 100Wh across an afternoon. Both cover it — the SOLIX C300 DC finishes at 41% used, and the HomePower 3000 barely notices it. For this job the HomePower 3000's extra capacity is dead weight, not headroom; take the SOLIX C300 DC at 6.2 lbs and leave the rest at home.

Conclusion
August 9, 2026
Verdict: the HomePower 3000, on Power Score margin
Take the HomePower 3000 if you need AC power, because it is the only unit here that has any: 3,072Wh behind 3,600W continuous and 7,200W of surge, with a 20ms handoff when the grid drops. The SOLIX C300 DC's surge rating is 0W because there is no inverter in it at all; the 300W on its spec line is the sum of its DC ports. Confidence sits at moderate not because the outcome is close but because the matchup is mismatched. The C300 DC is not a worse power station, it is a different product, and a buyer whose entire load charges over USB-C should ignore this verdict and keep the $1,199. Look at the scenario sweep the way it should be read: five wins for the Jackery and a sixth that beats both units is the shape of a category gap, not a contest.

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 C300 DC rates 4.4/5 (62nd percentile of 22 Personal-class units), and HomePower 3000 rates 4.7/5 (84th percentile of 26 Large-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 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 HomePower 3000 carries a real inverter behind 5 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.
The C300 DC Has Nothing to Switch Over
UPS means catching AC loads fast enough that they never notice the grid left. The HomePower 3000 does it in 20 milliseconds, which covers a desktop, a router and a refrigerator compressor. The C300 DC doesn't lack UPS the way one product lacks a feature another has; it has no AC output at all, so there's nothing to hand over. Read this as a category difference, not a missing checkbox.
Three Years Against Five, and What a Year Costs
Anker covers the C300 DC for 3 years, Jackery covers the HomePower 3000 for 5. Spread across the purchase, that's $67 per covered year against $240. Length matters less than what a claim costs you in practice: a six-pound bank goes back in a padded box, while a 59.52 lb unit out for service is a freight problem and a week without backup.
3,000 Cycles Against 4,000, and Why It Barely Signifies
Cycled once a day, the C300 DC's 3,000 cycles is 8.2 years and the HomePower's 4,000 is 11. Neither is likely to die of cycling. The difference is how they'll be used: 288Wh gets emptied constantly, so the small unit will actually work through its rating, while a backup box spends most of its life charged and idle between outages. Its higher number is a ceiling it will probably never approach.
Anker Doesn't Publish a dBA for the C300 DC
Jackery rates the HomePower 3000 at 30 dBA. Anker publishes no figure for the C300 DC, which is what raises this flag, and it's worth being precise about what it doesn't mean. A missing number is not a high number. With no AC inverter aboard, there's very little in this unit to make noise in the first place. Treat the blank as an undisclosed spec, not as evidence that it's the louder of the two.

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
Jackery's app is the weakest of the major brands, sitting between 2.3 and 3.3 out of 5, and it wants a login even offline. For a unit that mostly waits for a blackout, you'll open it rarely enough not to care. If live load monitoring is part of why you're buying, price that in as a real shortfall.
Analyst note
Support is the tiebreak nobody plans for, and neither brand is a comfort here. Anker's SOLIX desk has slipped from its old no-questions-asked standard toward scripted answers, and Jackery's is the one buyers route around by purchasing through Costco or Amazon so a retailer handles the return. That hedge matters far more on the Jackery, because 59.52 lb in need of service is a freight problem before it's a customer-service problem. A six-pound bank costs you an afternoon and a shipping label.
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 3000
FIXED CAPACITYFixed at 3,072Wh — a sealed, complete system rather than a starting point. There's no expansion port, so that figure is the ceiling: check it against your longest unplugged stretch before you buy.
Accepts up to 1,400W of solar. Enough for a serious multi-panel array.
Adequate ports for most setups, but heavy users may want a power strip.

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 HomePower 3000 gives you the larger ceiling); you can't add to either later.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
Anker SOLIX C300 DC
Field data on the C300 DC is thin, and most of what exists comes from reviewers rather than long-term ownersA1A2A4. It is at least consistent. The appeal is that Anker deleted the AC inverter to hold the weight near six poundsA1, the port set of four USB-C, two USB-A and a 12V socket covers a modern travel kit, and two-way USB-C with PD 3.1 brings the unit back to 80% in about an hourA2. Best Buy owners describe it doing precisely what that implies: several phone and laptop refills, a fan running for hours, a small light rigA3. Reviewers are also blunt about where the line sits, calling it a design for travelers charging devices rather than anyone running appliancesA4.
“A 288Wh unit that ditches the heavy AC inverter to focus on DC power, keeping it very light at about 6.2 lbs.”

Jackery HomePower 3000
The HomePower 3000's reputation rests on being small for what it holds. Reviewers call it the lightest and smallest 3kWh station available, carryable by one person at around 60 lb, with a 16.4-inch width that fits spaces rivals can'tB1. Backup testing supports the spec sheet rather than shading it: a standard refrigerator for nearly two days, a 55-inch TV for roughly 30 hours, and a grid-to-battery switchover measured under 20 millisecondsB4.
Two things are worth weighting beyond the unit itself. Jackery carries the lowest rate of reported failures and warranty claims among the major brands in owner communitiesB2, which matters more on a $1,399 purchase than on a $200 one. And the cycle rating deserves a note: Jackery and reviewers both put these LFP cells near 4,000 cyclesB3, which is the figure the spec table on this page uses, so the lifetime math above is built on the higher number rather than a conservative one.
“Described as the world's lightest and smallest 3kWh power station thanks to an advanced cell-to-body (CTB) design — one person can carry it at around 60 lbs, and its compact 16.4-inch width fits spaces that reject rivals.”

“Uses LiFePO4 chemistry with strong thermal stability; Jackery and reviewers rate the cells at roughly 4,000 cycles — notably higher than the figure in some spec listings, so treat lower cycle numbers with caution.”

Who Should Buy Which
Buy the SOLIX C300 DC if you…
- →You're packing for a week of flights and trains and your whole load is a laptop, a phone, a camera and a headlamp. Six pounds, 140W over USB-C, and it refills from the same charger you already carry.
- →You already own a large power station and want something for the day pack. This is a second unit, not a first one.
- →Your setup is 12V: a car fridge, DC lights, a fan. The 12V socket is the whole pointA2, and nothing you own needs an inverter.
Buy the HomePower 3000 if you…
- →The power goes out and you want the fridge, the router and two lamps not to notice. 3,600W continuous, 7,200W of surge for the compressor start, and a 20ms handoff so the desktop doesn't reboot.
- →You host the tailgate, run the job site, or are the person whose house everyone comes to when the street goes dark. 3,072Wh absorbs three people plugging in three things.
- →You want one box still worth owning in a decade. 4,000 cycles at 3,072Wh is 12,288 kWh of rated life, and 30 dBA means it can run in a room you're sitting in.
If neither fits
If you're genuinely torn between these two, there's a good chance neither is your unit. A 288Wh DC-only bank and a 3,072Wh home-backup box aren't competitors; they're different purchases that happen to share a category page. The buyer who wants to run a few normal AC things away from the house, a blender, a projector, a CPAP off its wall plug, needs a mid-size station with a real inverter, priced between these two and weighing between them too. Buying either of these instead means paying for capability you can't reach or capability you'll never lift.
The Bottom Line
If anything you're powering ends in a plug, the HomePower 3000 is the only unit on this page. That's not a close win and it isn't really a win, because the C300 DC has no inverter to lose with. Once you accept that, the $1,199 gap stops reading as a price comparison and starts reading as the price of an inverter, a 3,072Wh battery and a 20-millisecond handoff, which is roughly what those things cost.
And if nothing you're powering has a plug on it, close the tab and buy the little one. Six pounds, 140W of USB-C, and $1,199 still in your pocket is the right answer for a laptop-and-camera life. The mistake this page exists to prevent is buying the wrong category, and it's the same mistake in both directions.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Can the Anker SOLIX C300 DC run AC appliances?
No. It has no AC inverter and no wall outlets, which is why its surge rating is 0W rather than a low number. Its 300W figure is the combined output of its DC ports, and everything comes out over USB-C, USB-A or the 12V socket. If your load has a plug on it, this unit can't take it no matter what its capacity says.
Is the Jackery HomePower 3000 worth $1,399?
For AC backup, yes on the numbers: $1,399 across 12,288 kWh of rated life (3,072Wh × 4,000 cycles) is about a dime per kilowatt-hour, the cheapest energy on this page. What you're buying past the battery is 3,600W of inverter, 7,200W of surge headroom for compressor starts, and a 20ms UPS handoff. If you only ever charge devices, it's $1,199 more unit than the job requires.
Which one is better for camping?
The HomePower 3000, and the margin is boring: a 2,100Wh camping weekend sits at 80% of its 2,611Wh usable, while the C300 DC holds 245Wh. The catch is that 59.52 lb only camps where the car parks. If you're carrying gear any real distance, neither of these is the answer, and the C300 DC is the only one that would even come along.
Does the SOLIX C300 DC have UPS backup?
No, and it structurally can't. UPS means switching AC loads from grid to battery quickly enough that they don't drop, and the C300 DC has no AC output to switch. The HomePower 3000 is rated at 20ms and was measured under 20 milliseconds in backup testing, which is fast enough that a desktop or a router rides straight through the cut.
Can either of these run a CPAP overnight?
The HomePower 3000 handles it without noticing: an overnight CPAP load of 320Wh is 12% of its 2,611Wh usable, and Jackery publishes 30 dBA for a machine that will be sitting near your bed. The C300 DC loses this one on energy alone, since 320Wh is 131% of the 245Wh it holds after derating. It would run out before morning even if you solved the question of how to plug the machine in.
