Head-to-head test
Anker SOLIX C1000 vs BLUETTI Apex 300 + 2×B300K
These aren't two answers to one question: the C1000 goes where you go and the Apex stays where you install it, and since they cost within a penny per lifetime kilowatt-hour, the only thing left to decide is whether your power has to move.

Spec deltas
A 28-pound box you lift with one hand, against a 214-pound system you install once and never move again. These two aren't rivals so much as answers to different questions. The Anker SOLIX C1000 is 1,056Wh you can carry anywhere for about $450; the BLUETTI Apex 300 with two B300K packs is 8,294Wh you site in a corner for $3,699.
The surprise is the price per unit of energy. Spread each one's cost across every kilowatt-hour it will ever deliver, and the C1000 lands at about fourteen cents while the Apex lands at thirteen. Eight times the sticker, a penny apart in value. So the money isn't the deciding axis here, because neither is meaningfully cheaper to own than the other. What's left is need.
One question settles it: does the box have to move? If it does, for camping, a tailgate, a jobsite, anywhere but a fixed corner of your home, the Apex is out at 214 pounds before capacity even enters the conversation, and the C1000 is your unit. If it never moves and the load is whole-home or off-grid, the C1000's 898Wh usable taps out fast and the Apex is the only one of the two that does the job. There's no overlap where both fit.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Because 3,000-plus cycles on the C1000 and 3,500 on the Apex spread each unit's price across comparable lifetime throughput, neither is the better deal per unit of energy. Value can't break this tie, which strips the decision down to the two things that actually differ: how much energy you need, and whether you can lift it.
C1000: about $450 for 1,056WhApex: $3,699 for 8,294Whcost per lifetime kWh: $0.14 (C1000) vs $0.13 (Apex)rated cycles: 3,000 vs 3,500
Why it mattersAnyone weighing the Apex as overpriced or the C1000 as the value pick is on the wrong axis. Both are efficient. Decide on capacity and mobility instead.
The Apex's capacity only exists wherever you set it down; the C1000's exists wherever you're standing. So the moment a use case asks the unit to move, the matchup flips and the C1000 wins by walking out the door. The fork is mobility, not capacity.
C1000 weighs 28.4 lbsApex weighs 214 lbs (two-person lift, stationary)Tailgate Party: C1000 wins by default, the Apex can't travelWeekend Camping: neither, the Apex has the energy but can't go
Why it mattersIf your power has to travel, the Apex is disqualified before capacity is even discussed. Buy the C1000. If it never moves, capacity comes back onto the table.
That 898Wh usable is a one-appliance, part-of-a-day buffer, while the Apex's 7,050Wh usable is whole-home-for-a-day territory. There's no middle ground between them: you're either regularly under about 900Wh or you genuinely need the big bank, and nothing the C1000 does closes a 3,787Wh van-life gap.
C1000: 898Wh usableApex: 7,050Wh usable8-Hour Blackout needs 1,645Wh: C1000 short 747Wh, Apex spare 5,405WhVan Life Daily needs 4,685Wh: C1000 short 3,787WhRemote Workday needs 910Wh: C1000 short 12Wh
Why it mattersIf your real load is a full day of home backup or life in a van, the C1000 leaves you dark and the Apex is the only one of the two that finishes. Match the box to the load.
The specific dimensions that decide these two units — everything else is a tie.
Portability & Form Factor
Selected because: The whole decision pivots on one lift: 28.4 lbs you carry in one hand versus 214 lbs you install once and leave, which is a difference of category, not degree.
weight
The entire matchup turns on a single lift. 28.4 lbs is a one-hand grab off a shelf; 214 lbs is a two-person, set-it-and-forget-it appliance you position once and stop thinking about. That's not a portability advantage for the C1000, it's a different category of object.
The Apex's 8,294Wh only exists wherever you install it. The C1000's 1,056Wh exists wherever you're standing. So before capacity, before price, ask whether the power has to come with you. If it does, the Apex is already out, because 214 pounds doesn't load into a trunk or ride to a campsite. It stays home and waits for you to come back to it.
Your Life, Your Pick
Selected because: The load-fit split is clean: the C1000 owns everything that travels (it takes a 670Wh tailgate with 228Wh to spare), the Apex owns everything that stays home and runs big (5,405Wh to spare on an 8-hour blackout).
The scenario split reads like two different products because it is. Anywhere the unit has to travel, the C1000 wins by default: it takes the 670Wh tailgate with 228Wh to spare while the Apex can't reach the parking lot. Anywhere it stays home and the load climbs, the Apex runs away with it, covering an 8-hour blackout with 5,405Wh left over and a 4,685Wh van-life day with 2,365Wh to spare, both of which leave the C1000 thousands of watt-hours short.
The tell is the Remote Workday. The C1000 misses a single day at a desk by 12Wh, a rounding error that the flat 15% usable derate is enough to cause, since its 1,056Wh nameplate clears the 910Wh but its 898Wh usable doesn't. That's the ceiling of a 1kWh box. It's a one-appliance, part-of-a-day tool, and every scenario that asks for more belongs to the Apex.
Lifetime Value
Selected because: Per lifetime kilowatt-hour the two land a penny apart, $0.14 against $0.13, so the eight-times price gap is scale, not markup, and value can't pick a winner.
cost / lifetime kWh
Fourteen cents per lifetime kilowatt-hour for the C1000, thirteen for the Apex. An eight-times price gap, and they land a penny apart. That's because value here isn't the sticker, it's price spread across every kilowatt-hour the pack will ever deliver, and both are efficient at it, with 3,000-plus cycles on the C1000 and 3,500 on the Apex.
So drop the instinct that the Apex is expensive or the C1000 is the deal. Neither is. You pay for the energy you need, at about the same rate per unit, whichever size you buy, which is exactly why the decision has to be made on need and mobility rather than on which one is the better bargain.
What the Specs Don't Tell You
Selected because: The Apex brings the stronger inverter (7,680W surge vs 2,400W) but a two-person install and a base without built-in DC/USB ports; the C1000's one gap is that it publishes no noise figure at all.
rated cycles
Two catches deserve your attention, and they cut in opposite directions. The Apex's inverter is the stronger one: a 2x surge ratio and a 7,680W ceiling against the C1000's 1.3x and 2,400W, which is the difference between shrugging off a fridge or AC compressor's startup spike and tripping on it. But the Apex asks for things back. At $3,699 it's a two-person install, and its base ships without DC/USB ports on the face, so the roughly $300 Hub D1 add-on is effectively part of the priceB10B17.
The one honest gap on the C1000's side is noise. It publishes no figure at all, while the Apex at least lists 45dB. That isn't proof the C1000 is louder, it's that there's nothing to hold it to, so if a quiet room matters, treat it as a listen-before-you-commit flag rather than a spec you can trust.
Brand Trust
Selected because: Both carry the same 5-year warranty, so support quality is the real differentiator, and it matters more on the $3,699 unit than the $450 one.
Both units carry the same 5-year warranty, so coverage isn't the tiebreaker; support quality is. Anker's floor is higher, US-based and backed by a still-strong parent brand, but the SOLIX-specific service is drifting toward AI-driven canned replies, and returning a heavy unit means hazmat shipping logistics. BLUETTI's support is the category's most inconsistent, email-heavy with a China time-zone lag, and owners describe experiences ranging from smooth help to multi-week RMA runaroundsB4B11.
That inconsistency matters more on the Apex precisely because it's the $3,699 purchase. A coin-flip support experience is cheap to risk on a $450 box and expensive on one that costs eight times as much. If you go big, buy the Apex direct rather than through a reseller, since direct purchases tend to produce the better outcomes.

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
Neither gives you a powered weekend, for opposite reasons. The Apex has the energy, 7,050Wh usable against the 2,100Wh a weekend asks, and no way to bring it, since 214 pounds doesn't ride to a campsite. The C1000 comes along easily and taps out around 43% of the way through. A camping trip needs both traits in one box. Neither of these is that box.

Apex 300 + 2×B300K
The SOLIX C1000 doesn't finish — 898Wh usable against the 1,645Wh this needs leaves it 747Wh short, about 55% of the scenario covered. The Apex 300 + 2×B300K covers it with 5,405Wh to spare.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
A CPAP is about 40W for eight hours, so both cover the night with room to spare and capacity decides nothing. Fan noise would — but SOLIX C1000 doesn't publish a figure, so there's nothing to hold it to. Buy on price, weight, and whether you can live with a fan you haven't heard.

Apex 300 + 2×B300K
The C1000 misses a full day at a desk by 12Wh, the width of a phone top-up, and it's the flat 15% usable derate rather than the nameplate that tips it under: the 1,056Wh label clears the 910Wh, but 898Wh usable doesn't. Trim one small appliance's worth across the day and it finishes. The Apex covers the load outright with 6,140Wh to spare and never noticed it.

SOLIX C1000
This one goes to the C1000 by forfeit, then it earns the win outright. The Apex has plenty of power and will never see a parking lot, because 214 pounds doesn't tailgate. The C1000 rides in one hand and covers the 670Wh spread with 228Wh to spare. Capacity was never the Apex's problem here. Getting there was.

A 4,685Wh day is simply past what a 1kWh box was built for. The C1000 finishes about 19% of it and comes up 3,787Wh short, which isn't rationing, it's the wrong tool. The Apex closes the day with 2,365Wh to spare. If you're living out of the vehicle, this was always the Apex's scenario.

Conclusion
August 30, 2026
Verdict: the Apex 300 + 2×B300K, on Power Score margin
Call it a tie, but not because they're interchangeable. They never compete for the same job. Per lifetime kilowatt-hour they cost the same, about fourteen cents against thirteen, so value doesn't separate them. Weight does: 28 pounds goes where you go, 214 pounds stays where you put it. Need to carry it? The C1000, no contest. Powering a house or living off-grid from a spot it never leaves? The C1000's roughly 900Wh usable runs out before a single workday closes, and the Apex is the only one of these two that finishes. Buy for the job, not the spec sheet.

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 C1000 rates 4.6/5 (76th percentile of 26 Everyday-class units), and Apex 300 + 2×B300K rates 3.4/5 (7th percentile of 29 Whole-Home / Off-Grid-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
Apex 300 + 2×B300K: 213.9 lbs Is a Commitment
At 213.9 lbs, this is a two-person lift. Plan your placement carefully. Once it's set up, you won't want to move it. It's a semi-permanent appliance. Pick your spot.
Apex 300 + 2×B300K: 45dB Under Load
45dB is about as loud as a running refrigerator. The SOLIX C1000 publishes no figure to compare it against, which cuts both ways. For most people, fan noise around 45dB and up is where sleep starts to suffer.
The Apex starts what the C1000 might trip on
A 2x surge ratio and a 7,680W ceiling give the Apex real headroom for the half-second spike a fridge or AC compressor throws at startup. The C1000's 1.3x ratio and 2,400W ceiling are a thinner cushion, fine for its rated loads but the one more likely to stumble on a hard motor start. If you're running compressors off a fixed install, that headroom is a reason the Apex is built for it.
UPS Switchover: ≤10ms vs ≤20ms
Both list a UPS mode, at different rated speeds. The Apex 300 + 2×B300K is rated ≤10ms — quick enough on paper that desktop PCs and routers should ride through, treating that as the rating it is. The SOLIX C1000 is rated ≤20ms — fine on paper for routers and most electronics; the fussiest PC power supplies sit right at this line. If a computer with unsaved work is the thing being protected, the stated class is worth the attention; nothing here is a lab result.
Same five years, so ignore the per-dollar math
Both carry a 5-year warranty, so coverage isn't a tiebreaker. The per-dollar framing can fool you, since the C1000 works out to 11.1 years of cover per $1,000 spent against the Apex's 1.4, but that spread is just the price gap wearing a warranty costume. The terms are identical.
Battery Lifespan in Real Years
The Apex 300 + 2×B300K 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 8,294Wh on the Apex 300 + 2×B300K and 1,056Wh on the SOLIX C1000, so count lifetime energy — roughly 49,766 kWh against 3,168 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.
One of these publishes a noise number. One doesn't.
The Apex lists 45dB; the C1000 lists nothing. That isn't evidence the C1000 is louder, it means there's no figure to hold it to and no way to compare them on paper. If it's going in a bedroom or next to a CPAP, treat the Apex's 45dB as the only published number here, a spec-sheet floor rather than a measurement, and go find hands-on impressions of the C1000 before you commit.

App experience
Rated 4.5/5 iOS (~1,100 ratings) · 4.3/5 Android
Unique strength
Parent-brand trust from Anker's consumer-electronics track record, plus genuinely strong dollar-per-watt-hour in the mid-size units. The C1000 is one of the better value buys in the catalog on a per-Wh basis.
Worth knowing
Firmware updates have quietly removed features before, and the expansion ecosystem is smaller than the biggest rivals'. Neither is likely to bite a single-unit C1000 owner, but know it going in.
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, and it's the Apex's number-one risk. It's email-heavy with a China time-zone lag; some owners get smooth service, others get weeks of runaround. Buying direct rather than through a reseller tends to produce the better outcomes.
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 you can buy, and the widest lineup in the space, including 240V output and industry-first designs. If raw watt-hours per dollar at scale is the goal, this is the brand that specializes in it.
Worth knowing
Older or discontinued units can become hard to repair, and support communication can be erratic. On a $3,699 system you're betting on multi-year serviceability, so factor the inconsistency into the price.
Analyst note
Both brands make support you'd rather not have to test, but the failure modes differ. Anker's floor is higher and sliding; BLUETTI's is a coin flip that swings from great to grim. That coin flip is cheap to risk on a $450 C1000 and expensive on a $3,699 Apex, so if you go big, buy direct and keep your paperwork.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
Anker SOLIX C1000
Field data on the C1000 is genuinely strong, including a rare long-term data point: one reviewer ran the unit for over a year with no issues and about 97% of original capacity retained, and in a 30-day home-office UPS test it rode out seven brief outages with no equipment shutdowns or data lossA2. The consistent knock is fan noise, the fans spin up audibly during fast charging or heavy output near the unit's limit, comparable to a desktop fan at speed, though below roughly 500W it's nearly silentA1. Reviewers otherwise credit it for nailing the 1kWh fundamentals, fast AC recharge, a strong short-burst inverter, practical size, and useful app monitoringA3, and note it handles virtually any household appliance short of central AC and electric dryersA4.
“One reviewer used their unit for over a year with zero issues and minimal battery degradation — about 97% of original capacity. In a 30-day home-office UPS test it handled 7 brief outages with no equipment shutdowns or data loss.”

BLUETTI Apex 300 + 2×B300K
This is a 2025-launch system, so long-term owner data is thin, with nothing past about six months and no cold-weather reports at allB0. What exists skews toward a specific complaint about exactly this multi-battery configuration: owners charging the packs from the grid report they fill at different rates and fall out of sync, one at 100% and one at 50%, and BLUETTI support has called that normal behaviorB1B3. Solar-focused owners are the loudest, citing a 60V input ceiling they call misleading and a firmware bug that drops solar detection until you physically unplug and replug the cablesB8B9, and support experiences run polarized from smooth to weeks-long runaroundsB4B11. On the credit side, reviewers like the low, even fan note that stays usable near a workspaceB14, the efficient roughly 20W idle drain that stretches an outageB15, and the sheer run-a-day-of-essentials capacityB16. One recurring gotcha: the base ships without DC/USB ports on the face, so the roughly $300 Hub D1 is a near-mandatory add-onB10B17.
“For me the 240V output is great. I can stick it in the back of my PHEV and use the 240V output to charge at 3.3KW when I stop.”

- The base unit's 60V solar input ceiling and a firmware bug that drops solar detection (requiring an unplug/replug) are the two most-cited technical gripes among solar-focused owners. [Apex 300 + 2×B300K · 2 entries]
- Because the Apex 300 ships with no built-in DC/USB ports, owners and reviewers alike flag the mandatory ~$300 Hub D1 accessory as an unexpected added cost. [Apex 300 + 2×B300K · 2 entries]
- Despite being marketed as 'portable,' the unit's weight (~38kg/85lb base alone, more with B300K batteries) leads multiple sources to describe it as effectively a stationary/semi-permanent installation rather than something carried around. [Apex 300 + 2×B300K · 2 entries]

“Fan noise is the single most common complaint — the fans spin up audibly during fast charging or heavy output near the unit's limit, comparable to a desktop computer fan at speed. Under light loads (below ~500W) it's nearly silent.”

Who Should Buy Which
Buy the SOLIX C1000 if you…
- →The camper, tailgater, or road-tripper who needs power that travels. At 28 pounds it rides in one hand and covers a 670Wh tailgate with 228Wh to spare.
- →The apartment dweller or first-time buyer who wants a 1kWh cushion for phones, a laptop, a CPAP, and short outages without spending $3,699 or homing a 214-pound appliance.
- →Anyone whose real daily draw stays under about 900Wh usable and who values being able to grab the unit and go.
Buy the Apex 300 + 2×B300K if you…
- →The homeowner who wants genuine whole-home-for-a-day backup. 7,050Wh usable rides out an 8-hour blackout with 5,405Wh to spare, from a spot it never leaves.
- →The van-lifer or off-gridder with a 4,000Wh-plus daily draw, a fixed install location, and up to 2,400W of solar to feed it.
- →The buyer who needs 240V output or plans to grow the bank later and has a permanent home for a two-person-lift system.
If neither fits
If your need lives in the awkward middle, a real powered weekend away from the wall (2,000Wh and up) that you also have to carry, neither of these fits. The Apex can't travel and the C1000 can't finish. Look instead at a 2-3kWh portable in the 40-60 lb, one-cart-trip class that splits the difference.
The Bottom Line
These two never compete for the same buyer, and the only real mistake here is pretending they do. Per lifetime kilowatt-hour they cost within a penny of each other, so this was never a value contest. It comes down to one question: does the box have to move? Twenty-eight pounds goes with you. Two hundred fourteen stays where you set it.
Need to carry it, for camping, a tailgate, a work truck, a small apartment? Buy the C1000 and don't glance back at the Apex; it was never making the trip. Need to power a home or live off-grid from a fixed corner where 900Wh usable runs dry before lunch? The Apex is the only one of the two that finishes the day. Match the box to the job and either one is the right answer. Match it wrong and you're left holding a unit you can't lift or can't outlast.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Can the Anker SOLIX C1000 back up my whole house?
No. It's 1,056Wh, about 898Wh usable after the standard derate, which is enough for phones, a laptop, a CPAP, or a few hours of a fridge, not a house. An 8-hour blackout that needs about 1,645Wh leaves it roughly 747Wh short. For whole-home backup you want the Apex's 8,294Wh or another large system.
Is the BLUETTI Apex 300 actually portable?
Only in the sense that it isn't bolted down. At 214 pounds it's a two-person lift and a semi-permanent install, and reviewers routinely describe it as effectively stationary. Plan to pick a spot and leave it. If you need to move power around, that's the C1000's job.
Why does the Apex cost eight times more but nearly the same per kilowatt-hour?
Because you're buying about eight times the energy (8,294Wh vs 1,056Wh) and roughly 17% more rated cycles (3,500 vs 3,000). Spread over lifetime throughput, the C1000 works out to about $0.14 per kWh and the Apex about $0.13, nearly identical. The price gap is scale, not markup.
Which is quieter for a bedroom or CPAP?
You can't say for certain. The Apex publishes 45dB as a best-case floor and reviewers call its fan note even and unobtrusive near a sleeping area; the C1000 publishes no figure, and its one consistent complaint is fans spinning up under load, though it's nearly silent below about 500W. At a roughly 40W CPAP draw both sit in their quiet range, so this one comes down to hearing them yourself.
Do I need the extra Hub D1 accessory with the Apex?
Probably. The Apex base ships without DC or USB ports on the face, so most owners add the roughly $300 Hub D1 to get them. Budget for it as part of the system price. The C1000 has its ports built in.
