Anker SOLIX C300 vs BLUETTI Elite 300
Match the box to the load, not the name they share: past a couple hundred watt-hours the SOLIX C300 stops finishing jobs, and the Elite 300 that covers them costs less per kilowatt-hour over its life than the cheap one does to own.

Spec deltas
These two share a '300' and almost nothing else. The Anker SOLIX C300 is a 9.1-pound, 288Wh box for keeping phones and a laptop alive through an afternoon. The BLUETTI Elite 300 is a 58-pound, 3,014Wh battery that carries a house through a blackout. One is $330, the other $1,199, and that four-fold price gap is the smallest gap between them.
So the real question isn't which is better, it's which one matches your load, because the honest answer flips hard at the door. Anything past charging devices, whether a fridge, a CPAP overnight, or a full campsite, overruns the C300's 245 usable watt-hours, and the Elite covers it without breathing hard. And here's the twist that settles it for anyone on the fence: measured over its life, the Elite is the cheaper box to own, not just the bigger one.
The C300 isn't outclassed so much as out of category. If your list really is phones, a tablet, a laptop, and a fan for the evening, it does that job at a fifth of the weight and a quarter of the price, and the Elite's 3,014Wh is 49 extra pounds you'll resent hauling. Sort yourself by what you actually plug in, and this stops being a close call.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
The distance between these two isn't 'more headroom,' it's the line between a unit that quits before sunrise and one that runs the same machine about eight nights on a charge. For any load that runs all night, the C300 isn't a smaller Elite, it's the wrong tool.
SOLIX C300: 288Wh nameplate, 245Wh usable after the flat 15% derateCPAP Overnight scenario needs 320Wh; C300 falls 75Wh short (about three-quarters covered)Elite 300: 2,562Wh usable, covers the same night with 2,242Wh to spare
Why it mattersAnyone buying for overnight medical or comfort power should skip the C300 outright; the $330 doesn't buy a short night, it buys no night.
rated cycles
The $330 sticker is the only number on which the C300 wins. Measured by what you actually paid for, which is energy over the life of the thing, the Elite is the cheaper unit, not the pricier one.
SOLIX C300: $330, 288Wh x 3,000 cycles = 864 kWh over its rated lifeElite 300: $1,199, 3,014Wh x 6,000 cycles = 18,086 kWh over its lifeThat's roughly 21 times the lifetime energy for 4 times the price
Why it mattersIf you're choosing on value, the Elite wins that argument outright; the C300's real case is portability and up-front cash, never cost per kilowatt-hour.
weight
The 49-pound difference is the whole decision rendered as mass. It's the price of admission to real loads, and it's only worth paying when your load actually needs it; the moment it does, there's no substitute for it.
SOLIX C300 weighs 9.1 lbs; Elite 300 weighs 58 lbs (a 49-lb gap)For a 100Wh afternoon of phones and a speaker, the C300 finishes at 41% usedFor a 2,100Wh weekend or a 1,645Wh blackout, the C300 covers only about 12-15% before it's flat
Why it mattersSort yourself by load, not by price: device-and-laptop buyers pocket the $869 and the 49 pounds, while anyone running a fridge, a CPAP, or a blackout has to carry the 58 because the light one won't finish.
The specific dimensions that decide these two units — everything else is a tie.
Runtime: Will It Power Your Gear?
Selected because: Everything turns on one number: the C300's 245 usable watt-hours (288Wh less the standard 15% derate) against the Elite's 2,562, plus 300W continuous output versus 2,400W. That ceiling decides which loads each unit can actually run.
continuous output
One number governs the C300: 245, the usable watt-hours behind its 288Wh label after the flat 15 percent derate the site applies to every unit. That's the ceiling on everything it can do. Phones, a tablet, a laptop, and a fan for the evening all fit under it; a fridge, a kettle, or a CPAP running till morning don't.
Output draws the same line from the other direction. The C300 puts out 300W continuously and 600W in a surge, so it'll kick a 400W load to life and then stall the moment the continuous rating takes over. The Elite 300's 2,400W inverter, with 4,800W of surge, simply runs the thing. This is the section that decides the page: match the ceiling to your load, and the rest is footnotes.
Your Life, Your Pick
Selected because: Across the loads we model the C300 finishes exactly one outright, the 100Wh afternoon at 41% used; the Elite 300 clears every scenario in its class. The named nights make the capability gap concrete.
Run the C300 through the loads we model and it finishes exactly one outright: the 100Wh afternoon of phones and a speaker, where it lands at 41 percent used and the Elite's capacity is just ballast. Every other row it either quits early or can't sustain the draw, covering about 12 percent of a weekend, 15 percent of a blackout, and roughly three-quarters of a CPAP night before it's done.
The Elite 300 clears all of them in its class and only bows out of the van-life day at 4,685Wh, which is too big for either unit. The pattern isn't subtle. Below about 250 watt-hours of demand the C300 is the smarter, lighter pick; above it, the Elite is the only one of the two that shows up.
Lifetime Value
Selected because: The Elite delivers 18,086 kWh over its life against the C300's 864, working out to $0.07 per lifetime kilowatt-hour versus $0.35. The pricier box is the cheaper one to own, which reframes the whole choice.
cost / lifetime kWh
Here's where the price tag lies to you. The C300 costs a quarter as much up front, but over the life of each battery the Elite delivers 18,086 kWh against 864, roughly twenty-one times the energy for four times the money. Divide it out and the Elite works out to $0.07 per lifetime kilowatt-hour; the C300, $0.35.
The expensive box is the cheap one per unit of what you actually bought, which is energy. That doesn't make the C300 a bad buy, it makes 'cheaper' the wrong word for it: the C300 is cheaper to acquire, the Elite cheaper to own.
Portability & Form Factor
Selected because: The C300's entire case is 9.1 pounds against the Elite's 58, a 49-pound gap. For small jobs that weight saving is the point; for real loads it's the toll you pay for a unit that finishes.
weight
The C300's whole argument weighs 9.1 pounds. You lift it with one hand and forget it's in the bag. The Elite 300 is 58, a two-handed, mind-your-back load, and BLUETTI got it as compact as any 3kWh unit on the market, certified smallest-by-volume as of early 2026B2, but 58 pounds is still 58 pounds.
That 49-pound gap is the entire decision rendered as mass. For the beach, the picnic table, or the hotel room, the extra weight buys you nothing you'll use. For a blackout or a weekend off-grid, it's the price of a unit that finishes the job. Pick up both and you'll know which one you are.

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
Elite 300
A full weekend of camp loads, lights, a cooler, charging, some cooking, runs about 2,100Wh. The C300 covers roughly an eighth of that; it's the device-charger you bring to camp, not the camp's power supply. The Elite 300 finishes the weekend with 462Wh still in reserve.

SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
Elite 300
Eight hours of the essentials needs about 1,645Wh, and the C300 carries roughly 15 percent of it before it's flat. The Elite 300 finishes the outage with 917Wh in the tank, enough to roll into a second evening, and its 1,200W solar input against the C300's 100W means a sunny morning puts real energy back. In a blackout the small unit charges your phone; the big one keeps the lights and the fridge.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Elite 300
A 288Wh box sounds like plenty for a quiet overnight load, and it isn't quite. The C300 has 245 usable watt-hours against the roughly 320 a CPAP wants across a night, so it covers about three-quarters and quits before morning, 75Wh short. The Elite 300 runs the same machine about eight nights between charges. If the load sleeps next to you, size up.

Elite 300
The SOLIX C300 doesn't finish — 245Wh usable against the 910Wh this needs leaves it 665Wh short, about 27% of the scenario covered. The Elite 300 covers it with 1,652Wh to spare.

Elite 300
The SOLIX C300 can start the 400W peak but not hold it — 600W of surge gets it going, then the 300W continuous rating takes over. The Elite 300 handles this scenario with 1,892Wh to spare.

A full day of mobile living — the ultimate endurance test
Neither unit
Neither unit covers this scenario's 4,685Wh: the SOLIX C300 comes up 4,440Wh short (about 5% covered), the Elite 300 2,123Wh (55%). This is well outside what either unit is for; the right answer here is a larger station, not a choice between these two.

Afternoon Off-Grid
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's class of job: phones and a speaker, 100Wh across an afternoon. Both cover it — the SOLIX C300 finishes at 41% used, and the Elite 300 barely notices it. For this job the Elite 300's extra capacity is dead weight, not headroom; take the SOLIX C300 at 9.1 lbs and leave the rest at home.

Conclusion
August 30, 2026
Verdict: the Elite 300, on Power Score margin
Buy the Elite 300 unless your loads are genuinely small, and be honest with yourself about which that is. It clears every scenario in its class with hundreds to thousands of watt-hours to spare, where the C300's 245 usable Wh taps out at 12 to 27 percent of the same jobs and can't even finish a CPAP night. It's also the cheaper unit to own over its life and lasts twice the rated cycles. The C300 earns its keep only for the phones-and-a-laptop buyer who prizes 9.1 pounds and a $330 outlay over capacity: a real buyer, just a narrower one than most who land here expecting a '300' to back up a home.
Today the Elite 300 is $1,099, $100 under its typical $1,199. The verdict weighs typical prices, not today's. Prices checked 1 day ago.

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 4.2/5 (52nd percentile of 22 Personal-class units), and Elite 300 rates 4.6/5 (76th 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.
Same five years, with one asterisk
Both list a 5-year warranty, so coverage isn't the tiebreaker. One thing the spec sheet won't tell you: BLUETTI's full term generally wants a direct purchase or registration, and buying the Elite through a third-party reseller can drop you to as little as two years. Register it either way. And ignore the per-dollar framing that makes the C300 look like more warranty; that's the lower price talking, not better terms.
Battery Lifespan in Real Years
The Elite 300 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. One caution reading years across different sizes: a cycle is 3,014Wh on the Elite 300 and 288Wh on the SOLIX C300, so count lifetime energy — roughly 18,086 kWh against 864 kWh over the rated life. After hitting the cycle limit, the battery doesn't die — it drops to ~80% of original capacity, which is still very usable.
The Elite's noise is a blank, not a boast
The C300 lists 25dB; BLUETTI publishes no noise figure for the Elite 300. That's not proof it's louder, it's the absence of a number to hold it to. And the 25dB is itself a best-case, quiet-mode spec rather than a measurement, so don't read it as silent. If either unit is going in a bedroom or beside a desk, find a hands-on noise report before you decide, because the spec sheet can't settle this one.

7-8 SOLIX portable power stations across C-series (compact) and F-series (flagship), plus the X1 home energy system
Support
US-based, and Anker's name still carries goodwill, but SOLIX support specifically is trending down: recent reports describe AI-driven first-line agents giving generic answers and painful hazmat return logistics on heavier units.
Community
Moderate — active Reddit (r/Anker, r/AnkerSOLIXCommunity) and growing. Benefits from Anker's massive consumer electronics brand awareness.
App experience

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
The C300 is light enough that the hazmat-return headache is far less likely to bite than it would on Anker's big F-series boxes.
BLUETTI
Ecosystem
One of the broadest lineups — 15-20+ models from budget (AC2A) to flagship portable (Apex 300, 2764.8Wh). Includes specialized products: vehicle solar hubs, sodium-ion cold-weather units, and balcony storage systems.
Support
The most inconsistent support in the category, heavily email-based with timezone delays, and outcomes swing from smooth to weeks of runaround. Buying direct from BLUETTI reliably produces better service, and as noted it also protects the full warranty term.
Community
Active and growing — Reddit r/bluetti has a dedicated community. Second-largest after EcoFlow in engagement.
App experience
Rated 4.5/5 iOS and Android — tied for best app experience in the category. V3.0 UI redesign was well-received.
Unique strength
Among the best capacity-to-price ratios available — several Elite and Apex units are the lowest $/Wh in the catalog. Widest product diversity including industry-firsts like sodium-ion cold-weather units and dual solar+alternator vehicle hubs. LFP across the rest of the range, though rated cycle life spans 2,500 (EB3A) to 6,000, and it varies WITHIN the Elite range rather than tracking it — the Elite 300 and Elite 200 V2 are rated 6,000 while the Elite 30 V2, Elite 10 Mini, Elite 320 and Elite 400 are rated 3,000+ and the Elite 100 V2 4,000+, so check the specific model. Dual-voltage (120V/240V) in flagships.
Worth knowing
BLUETTI runs one of the widest lineups in the space, so the Elite 300 sits in a well-populated family with shared cell tiers and accessories rather than off on its own.
Analyst note
Neither brand's support is a reason to pick it: both are inconsistent, and both reward buying direct. So support doesn't break this one. The decision stays exactly where it started, on what you need to power and what you'll pay per kilowatt-hour to power it.
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.
Adequate ports for most setups, but heavy users may want a power strip.
Elite 300
FIXED CAPACITYFixed at 3,014Wh — 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 1,200W of solar. Enough for a serious multi-panel array.
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 Elite 300 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 keep circling the same three things: it's impressively light and compact for 288Wh, the dual 140W USB-C ports charge a phone and a laptop fast, and the 10ms UPS switchover is genuinely rare at this size and priceA1A2A3. That last point is a highlight for the C300's class, but it isn't a wedge here: the Elite matches the sub-10ms switchover, so it's parity rather than an edge. Worth flagging that some listings blur the AC C300 with a DC-only 'C300 DC' and a 'C300X'; this comparison is the standard model with the AC inverterA0. What's missing is long-haul owner data, so read most of this as review-cycle coverage, not years-in reports.

What owners complain about
No ability to add an expansion battery, so he must go DIY to reach 8kWh for his camper.

Claims are weighted by how specific they are, whether the commenter owns the unit, and how many readers agreed. Comments that mention a product under a rival's review count for more, because the commenter had no reason to be there. This is what buyers report, not our test results — for measurements we ran ourselves, see the methodology.
Who Should Buy Which
Buy the SOLIX C300 if you…
- →The device buyer: phones, a tablet, a laptop, and a fan across an afternoon. At 9.1 pounds and $330, the C300 does that job and the Elite is 49 pounds of overkill for it.
- →The ultralight traveler for whom 58 pounds is a non-starter, who values weight and packability over capacity and will top up from a wall or car outlet each night.
- →The road-tripper charging small DC gear and a laptop, who needs a backup for things, not a backup for a room.
Buy the Elite 300 if you…
- →Anyone with a real AC load: a fridge, a CPAP overnight, an evening of blackout essentials, or a full weekend of camp. The Elite's 2,562 usable watt-hours cover all of it with margin.
- →The home-backup buyer who wants one box to carry the essentials through an outage, with 1,200W of solar input to put energy back on a sunny morning.
- →The value buyer who plans to keep it for years: $0.07 per lifetime kilowatt-hour, 6,000 cycles, and about sixteen years of daily use.
If neither fits
The van-lifer or off-gridder pulling 4,685Wh a day should skip both: neither finishes, with the C300 covering about 5 percent and the Elite about 55 percent, so you want a larger station or a proper house bank. Same for anyone needing to run a well pump, an EV, or a whole-home transfer, which is a different category of hardware entirely.
The Bottom Line
Buy the Elite 300 if you have a real load and the C300 if you don't, and be honest with yourself about which that is. The tell is right on the spec sheet: 245 usable watt-hours finishes an afternoon of phones and a laptop and almost nothing else, while 2,562 carries a weekend, a blackout, or about eight CPAP nights.
The Elite asks $1,199 and 58 pounds for that reach, then quietly hands most of it back as the lower cost per kilowatt-hour over its life. The C300's case is real but narrow: 9.1 pounds, $330, and a job list that ends at charging things. Figure out what you're plugging in, and the box picks itself.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Can the Anker SOLIX C300 run a CPAP overnight?
By our model, which puts a CPAP night at about 320Wh, not quite. The C300 has 245 usable watt-hours, so it falls roughly 75Wh short and covers about three-quarters of the night before it's flat. A CPAP with a heated humidifier or heated hose draws more and makes it worse. If overnight medical power is the job, the Elite 300 runs the same machine about eight nights on a charge; get the bigger unit or a mid-size one, not the C300.
Why is the Elite 300 cheaper per kilowatt-hour if it costs four times as much?
Because you pay once and use it far longer. Over its rated life the Elite delivers 18,086 kWh against the C300's 864, which is about twenty-one times the energy for four times the price. That works out to $0.07 per lifetime kilowatt-hour versus $0.35. Up front the C300 is cheaper; per unit of energy you'll ever get out of it, the Elite is.
Is the SOLIX C300 too small to be useful?
No, it's just sized for small jobs. For phones, a tablet, a laptop, and a fan across an afternoon, roughly 100Wh, it finishes at 41 percent used and weighs 9.1 pounds. It becomes the wrong tool the moment your load includes a fridge, a kettle, or anything that runs all night.
Which is quieter for a bedroom?
The C300 is the only one of the two with a published figure, 25dB, and even that is a spec-sheet best case rather than a measured number under load. BLUETTI doesn't publish a noise spec for the Elite 300, so there's nothing to hold it to. If it's going next to your bed, treat the 25dB as the only number on the table and look for a hands-on noise report on the Elite before you commit.
Do the SOLIX C300 and Elite 300 actually compete with each other?
Not really. They share a '300' in the name and little else: 288Wh versus 3,014Wh, $330 versus $1,199, 9.1 versus 58 pounds. One tops up your devices, the other backs up your evening. Decide what you're powering, and the choice makes itself.
