Head-to-head test
Anker SOLIX C300 vs DJI Power 1000
The C300 is the power station you actually carry — 9.1 lbs, gone in a daypack; the Power 1000 is the one you plan a trip around, at 28.7 lbs and a 2,200W inverter. The real question isn't which one wins on paper, it's which weight class your trips actually need.

Spec deltas
The Anker SOLIX C300 and the DJI Power 1000 aren't really built for the same job. The C300 holds 288Wh and weighs 9.1 lbs; the Power 1000 holds 1,024Wh and weighs 28.7 lbs — 736Wh and nearly 20 lbs of difference before either spec sheet gets interesting.
DJI prices the Power 1000 like the more serious tool it is — $699 against the C300's $300 — and the spec sheet backs that positioning up: more than 3.5 times the capacity and a 2,200W inverter against 300W. Run the true cost of ownership, though, and the bigger price tag turns out to be the better deal per watt-hour, not just the pricier one.
Run the six real-world scenarios and the C300 doesn't outright win a single one — it's simply sized for lighter jobs than most of them ask for. The Power 1000 clears CPAP Overnight and Tailgate Party on its own; everything bigger than that, a full weekend of camping, an 8-hour blackout, a day of van life, runs out both units. The decision that actually matters here isn't which station is 'better.' It's whether your trips ever ask for more than a phone, a laptop, and a light.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
The split here isn't small unit versus big unit, it's big unit versus still-not-big-enough unit. The Power 1000's real advantage only shows up under roughly 700Wh of demand (Tailgate Party, CPAP Overnight), which is exactly where the C300 has already run out.
C300 holds 288Wh; Power 1000 holds 1,024Wh — 736Wh moreWeekend Camping needs about 2,100Wh (Power 1000 needs 241% of its own capacity to cover it) and Van Life Daily needs about 4,685Wh (538% of the Power 1000's capacity)
Why it mattersAnyone picturing a full weekend off-grid or a real household blackout should be shopping a bigger class of station than either of these, not splitting hairs between them.
solar input
At 100W, putting the C300's own 288Wh back takes the better part of a good solar day. At 800W, the Power 1000 can put back several times that in the same window — which matters precisely because both units already come up short on the scenarios where a mid-trip recharge is the only way to close the gap.
C300 accepts up to 100W of solar input; Power 1000 accepts up to 800W — 8 times as muchWeekend Camping needs about 2,100Wh and 8-Hour Blackout needs about 1,645Wh, loads neither unit covers on battery alone
Why it mattersAnyone planning to bridge a multi-day trip with solar rather than wall power should weight that gap heavily — it's the difference between actually recharging during the day and just watching a panel do very little.
continuous output
9.1 lbs is a one-hand grab off a shelf on the way out the door. 28.7 lbs is a two-hand lift you plan for, and that's the tradeoff for headroom to run a hot plate, a space heater, or a compressor fridge that would trip the C300's inverter outright.
C300 weighs 9.1 lbs against the Power 1000's 28.7 lbs — 19.6 lbs moreC300 tops out at 300W continuous output (600W surge); Power 1000 runs 2,200W continuous (4,400W surge)
Why it mattersIf a phone, a laptop, and a light are the whole job, the extra 19.6 lbs is dead weight to carry. If anything in the plan draws real heat, only one of these two can run it.
The C300's 10ms switchover is the faster of the two and genuinely useful for anything twitchy about power gaps, but a fast switchover doesn't help on a battery that runs dry partway through the night. The Power 1000's slightly slower 20ms hand-off comes with the capacity to actually reach morning.
CPAP Overnight needs about 320Wh; the C300 (288Wh) can't clear that on its own, while the Power 1000 uses only 37% of its capacityC300 switches to battery power in 10ms; Power 1000 in 20ms
Why it mattersA CPAP buyer should size on capacity here before switchover speed — the Power 1000 is the one built to get you to sunrise.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: Six real loads show the size gap directly — the C300 doesn't clear any outright, the Power 1000 clears two.
Two of six scenarios land on an actual winner, and both go to the Power 1000. CPAP Overnight needs roughly 320Wh, more than the C300's full 288Wh — the smaller unit can't finish the night, while the Power 1000 uses just 37% of its capacity. Tailgate Party asks for about 670Wh; the C300 runs out before it gets there, and the Power 1000 clears it using 77% of what it has.
The other four go to neither, and the near-misses matter as much as the outright misses. Remote Workday needs about 910Wh, and the Power 1000 comes up just short too, at 105% of its own capacity — even the bigger unit isn't quite enough for a full day of laptop-and-monitor work. Weekend Camping, an 8-hour blackout, and Van Life Daily ask for even more, up to 4,685Wh for van life, putting them out of reach of either station. That's not a flaw in either unit. It's a sign those jobs call for a different category of gear.
Lifetime Value
Selected because: Sticker price and true cost-per-kWh point in different directions; that tension is the crux of a size-mismatch pair.
cost / lifetime kWh
Sticker price says C300, cost per lifetime kWh says Power 1000 — and the second number is the one that should decide a purchase you'll own for years. The C300 costs $0.35 for every kWh it delivers over its rated cycle life; the Power 1000 costs $0.17, roughly half, because $699 buys more than 3.5 times the capacity on a battery rated for 1,000 more cycles.
The same story shows up before cycle life even enters the picture. At raw purchase price, the C300 runs $1.04 per Wh of capacity against the Power 1000's $0.68. There isn't a price-efficiency number on this page that favors the C300 — its case has to rest on something other than cost per unit, which is exactly what the rest of this page is for.
Portability & Form Factor
Selected because: 9.1 lbs vs 28.7 lbs is the C300's entire case for existing — it earns its own section, not a line item.
weight
9.1 lbs is a one-hand grab off a shelf on the way out the door. 28.7 lbs is a two-hand lift you plan for — set it down, don't drop it on your foot. That's 19.6 lbs of difference, and it isn't arbitrary: the extra weight is an inverter built for 2,200W continuous instead of 300W, plus a battery holding more than three and a half times the energy.
For a buyer whose heaviest device is a laptop, the C300's whole pitch is that you stop noticing it's in the bagA1A2. The Power 1000 doesn't lose that fight because it's a worse design. It's simply not competing for that job — it's the unit you carry because you need the 2,200W inverter and the capacity behind it, not because you forgot it was there.
What the Specs Don't Tell You
Selected because: UPS speed, warranty value, and cycle life all fire and are genuinely informative here, not dealbreakers.
rated cycles
None of the three call-outs here are red flags — all three read as informational, which fits a pair where nothing is actually broken, just priced and sized differently. UPS speed favors the C300, raw cycle count favors the Power 1000, and the warranty is a flat tie at 5 years on both.
Worth noticing is how little any of the three should move the decision on its own. A faster switchover only matters if you're running something that hates a power gap; a higher cycle count only matters if you'll actually put thousands of cycles on the unit; and a tied warranty length says nothing about what a year of that coverage is worth on a $300 unit versus a $699 one. The specifics are in the cards below — the headline is that these are details, not deciding factors.
Brand Trust
Selected because: Cross-brand at a real price gap ($300 vs $699) — Anker's support trend and DJI's short track record both matter at this spend.
Anker is the established name here, a consumer electronics giant whose SOLIX lineup spans compact and flagship power stations, but the C300 arrives alongside real signs that support quality is sliding from where it used to be, including AI-driven support responses and complicated return logistics for heavier units. DJI is the opposite shape: almost no power-station track record (its first model shipped in 2024), leaning instead on the global repair network it already built for drones.
Judge the Power 1000 on build and you get the DJI story that actually shows up in reviews — quiet running and dependable output under sustained loadB1B2 — which lines up with a company applying drone-grade engineering to a new category rather than cutting costs to hit a price. The honest risk is the one DJI can't paper over yet: two years isn't long enough to know how the battery ages, and there's no expansion ecosystem if you outgrow one unit.

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
A full weekend of camping calls for about 2,100Wh. The C300 would need 858% of its own capacity to cover it and the Power 1000 needs 241% — both fall well short, so this load calls for a larger station or a plan to recharge mid-trip.

8-Hour Blackout
Keep the essentials running through a night without power
Neither unit
An 8-hour blackout runs about 1,645Wh. The C300 would need 672% of its capacity and the Power 1000 189% — neither gets a household through eight hours solo. Treat either as a bridge for the essentials, not whole-house backup.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Power 1000
A CPAP overnight draws about 320Wh, more than the C300's full 288Wh capacity — it can't finish the night alone. The Power 1000 uses just 37% of its capacity for the same load, with plenty of margin to spare.
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
Neither unit
A remote workday of laptop, monitor, and charging runs about 910Wh. The C300 would need 372% of its capacity; the Power 1000 comes close at 105% but still falls just short on its own. Plan on a midday top-up with either one.

SCN-05 · 4 hours · needs 670Wh
Tailgate Party
Game day power for the crew
Power 1000
A tailgate setup draws about 670Wh. The C300 runs out before the party's over; the Power 1000 covers it with 77% of its capacity used, leaving enough for a few more hours.

Van Life Daily
A full day of mobile living — the ultimate endurance test
Neither unit
Full-time van living runs about 4,685Wh a day. The C300 would need 1,914% of its capacity and the Power 1000 538% — this is solar-plus-multiple-battery territory, well beyond what either single station is built for.

Conclusion
July 28, 2026
Verdict: the Power 1000, on Power Score margin
The Power 1000 wins the numbers that decide long-term ownership: $0.17 per lifetime kWh against the C300's $0.35, a 2,200W inverter that can actually start real appliances, and both of the scenario wins either unit posts outright, CPAP Overnight and Tailgate Party. The C300 isn't a worse unit for it — at 9.1 lbs and $300 it's built for a different job, keeping phones and small gear charged on the move rather than running a householdA1A2. Buy the Power 1000 if your loads have any real weight to them; buy the C300 if they never do and carrying it is the whole point.

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 C300 rates 4.4/5 (67th percentile of 22 Personal-class units), and Power 1000 rates 3.9/5 (35th 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.
UPS Speed: line-interactive (<10ms) vs standby (<20ms)
The C300 switches to battery power in 10ms; the Power 1000 takes 20ms. Both qualify as fast, line-level protection — the practical difference shows up only with equipment that's genuinely sensitive to a power gap, like a desktop PC or certain medical devices.
Warranty Value Comparison
Both units carry a 5-year warranty, a tie on paper. Priced out, that's about $60 a year of coverage on the C300 and $140 a year on the Power 1000 — the gap tracks the purchase price, not the coverage terms, which are identical.
Battery Lifespan in Real Years
3,000 rated cycles on the C300 against 4,000 on the Power 1000. Used once a day, that's roughly 8.2 years versus 11; used once a week, both stretch past 50 years. Either way, cycle life is unlikely to be the reason either unit gets replaced.

Brand trust
Anker
Ecosystem
Anker's SOLIX line runs 7 to 8 power stations across a compact C-series and a flagship F-series, plus the X1 home battery system — there's a step up available if the C300 turns out too small.
Support
Historically the standout in this category for no-hassle replacements. Recent support has leaned more on AI agents giving generic answers, and returning a heavier unit means dealing with hazmat shipping rules — worth knowing before a return is needed, not after.
Community
A moderate but active presence on Reddit, riding on Anker's much larger name recognition in consumer electronics generally.
App experience
Rated 4.5/5 iOS (~1,100 ratings) · 4.3/5 Android
Unique strength
InfiniPower tech built for long cycle life, and Gen 2 SOLIX pricing that's among the better dollar-per-Wh value in the category.
Worth knowing
Firmware updates have quietly removed features on past SOLIX units, and the expansion lineup is smaller than some rivals'.
DJI
Ecosystem
Four models deep as of 2024 — Power 500, Power 1000 V2, Power 1000 Mini, and Power 2000 — a young lineup next to Anker's, with no expansion batteries yet.
Support
Backed by the global service network DJI already runs for its drones, with a strong reputation inherited from that business, though power stations themselves don't have much of a track record yet.
Community
No power-station-specific community to speak of. What discussion exists lives inside the much larger r/dji, and it's mostly drone owners.
App experience
Rated 3.5/5 iOS and Android (DJI Home app ratings reflect entire DJI ecosystem including drones/cameras, not power-station-specific). Users report the on-device screen is more reliable than the app.
Unique strength
The quietest running in the category, fast wall-charging on the newer V2 model, and industrial design that reads as engineered rather than cost-optimized — the drone-patent pedigree shows.
Worth knowing
No built-in solar charge controller — solar needs a separate proprietary adapter — and the fast SDC charging ports only pay off if DJI drone gear is already in the bag.
Analyst note
Anker is the safer bet on paper: more history, a bigger community, a clearer upgrade path. But its support has real, recent cracks. DJI is the newer name carrying none of that baggage yet, backed by a company that knows how to build and service hardware — the tradeoff is that 'yet' is doing some real work in that sentence.
Growth path
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.

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 Power 1000 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
Reviewers consistently land on the same three things: a build that's genuinely compact and light for what it holds, dual 140W USB-C ports fast enough to charge a laptop and a phone at once, and a 10ms UPS switchover that's unusual to see at this size and priceA1A2A3. Anker pitches it at hikers and campers topping off phones and small gear, and the coverage backs that framing rather than positioning it as a whole-campsite unitA2A4.

DJI Power 1000
The recurring theme in Power 1000 coverage is how quiet it runs — reviewers rank it among the quietest stations in its class, describing the fan as barely noticeable even under heavy load and never harsh the way some rivals getB1. It's also been pushed past its 2,200W rating in testing and held up without shutting down or getting loudB2. Over multi-day real-world camping use it ran a compressor fridge alongside phones, laptops, and lights without complaint, and it's picked up a following among drone pilots who like charging flight batteries off it while running other gear at the same timeB4.
“Whisper-quiet operation — one of the quietest power stations in its class, nearly silent under normal loads; sound only becomes noticeable past 1,500W, and even then it's a soft whoosh rather than the high-pitched whirring you'd get from BLUETTI or EcoFlow.”

Who Should Buy Which
Buy the SOLIX C300 if you…
- →Your heaviest device is a laptop, and the trips are day hikes or weekend errands, not multi-day camping. At 9.1 lbs the C300 goes in the bag without becoming the reason the bag is heavy, and the coverage backs up that it's genuinely built for that job rather than just marketed that wayA1A2.
- →You want fast UPS protection for something that hates even a short power gap — a desktop, a modem, a small sensitive device — and don't want to pay for capacity that load will never touch. The C300's 10ms switchover and $300 price do that specific job well.
Buy the Power 1000 if you…
- →You're running anything with a real motor or heating element — a compressor fridge, a hot plate, power tools — where the C300's 300W inverter can't start the load. The Power 1000's 2,200W continuous rating is built for exactly that, and it's the unit that actually clears CPAP Overnight and Tailgate Party, not just on paper.
- →You're keeping the unit for years, not one season. At $0.17 per lifetime kWh against the C300's $0.35, the Power 1000 is the cheaper station to own once you count the energy it actually delivers over its rated 4,000 cycles — the higher sticker price is buying scale, not markup.
If neither fits
If the real need is a full weekend off-grid, an 8-hour whole-house blackout, or powering a van full-time, neither of these covers it — Van Life Daily alone runs about 4,685Wh a day, more than four times the Power 1000's own capacity. Look at a larger single station built for that scale, or a system with expansion batteries, instead.
The Bottom Line
The Power 1000 wins the numbers that matter for ownership: $0.17 per lifetime kWh against the C300's $0.35, a 2,200W inverter that actually starts real appliances, and the only two scenario wins either unit posts outright, CPAP Overnight and Tailgate Party. None of that makes the C300 wrong — at 9.1 lbs and $300 it's built to be the one you actually grab, not the one you talk yourself out of carryingA2.
Buy the Power 1000 if your loads ever get past a phone and a laptop. Buy the C300 if they don't, and let carrying it without a second thought be the whole point.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the DJI Power 1000 just a bigger, better version of the Anker SOLIX C300?
Not really — they're sized for different jobs. The C300 (288Wh, 9.1 lbs, $300) is built to disappear into a bag and keep phones and small gear charged; the Power 1000 (1,024Wh, 28.7 lbs, $699) carries the 2,200W inverter to run real appliances. Bigger, yes. Better only if your loads actually need that headroom.
Which one is actually cheaper to own, not just to buy?
The Power 1000, even though it costs more upfront. Priced per lifetime kWh — what you pay divided by everything the battery will ever deliver over its rated cycle life — the C300 runs $0.35 and the Power 1000 runs $0.17. The bigger unit's extra capacity and 1,000 additional rated cycles spread its $699 price over far more total energy.
Can either of these run a CPAP all night?
Only the Power 1000, cleanly. A CPAP overnight draws roughly 320Wh, more than the C300's full 288Wh capacity, so it won't make it to morning alone. The Power 1000 uses only about 37% of its capacity for the same night, with plenty of room to spare.
Is the C300's faster UPS switchover a reason to pick it over the Power 1000?
Only if you're protecting something genuinely sensitive to a power gap, like a desktop computer. The C300 switches to battery in 10ms against the Power 1000's 20ms, and both are fast enough for most electronics — but if the device in question reboots on anything slower than instant, the C300's switchover is the faster of the two.
Do either of these expand if I need more capacity later?
No — neither has an expansion battery option, so what you buy is what you're stuck with. Size for actual needs up front: the Power 1000's 1,024Wh is the larger ceiling of the two, but outgrow either one and the fix is a second unit or a bigger station, not an add-on.
