Anker SOLIX F2600 vs BLUETTI Apex 300 + 2×B500K
Per watt-hour these two cost within a penny of each other, so the whole decision is whether you need 2,560 watt-hours you can carry or 13,005 that weigh 282 pounds and never move.

Spec deltas
These two barely belong in the same comparison: a 70.5-pound portable you can wrestle into a trunk, and a 282-pound, 13,005Wh system that goes where two people set it down and stays put for good. The Anker F2600 costs $1,100. The BLUETTI Apex 300 with two B500K batteries costs $5,399. That's five times the money, and it buys five times the watt-hours at almost exactly the same rate per watt-hour.
So this isn't a value fight. Per watt-hour the two cost within a penny of each other; you're not paying a premium for the big one, you're paying for five times as much capacity. The only question that matters is whether you need that capacity, and whether you can live with the box that holds it never leaving one room.
For most people the honest answer is the F2600. It clears a single blackout, a workday, a campsite and a tailgate with room to spare, and one person can pick it up. The Apex earns its price in exactly one situation: when your daily draw or your outage runs long enough that 2,560Wh runs dry, and you've got a fixed place to keep a 282-pound battery fed by up to 2,400W of solar. If that's you, size up. If it isn't, you're buying watt-hours you'll never spend.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Typical price
Five F2600s would run about $5,500, roughly the price of the single $5,399 Apex, and still leave you with five separate boxes, five chargers, and no unified 240V or 2,400W solar input. If you genuinely need around 13,000Wh, the Apex is the cleaner and marginally cheaper way to get there. If you don't, its price is simply capacity you won't use.
F2600: $1,100 for 2,560Wh, about 43 cents per watt-hourApex 300 + two B500K: $5,399 for 13,005Wh, about 42 cents per watt-hourmatching 13,005Wh with F2600s takes five units (5 x 2,560 = 12,800Wh) at five x $1,100, about $5,500
Why it mattersSize to your real load: the Apex is the right buy for a true 13,000Wh need and the wrong buy for a 2,560Wh one, at nearly the same rate per watt-hour.
The one scenario the F2600 can't cover is Van Life Daily's 4,685Wh, a multi-day or whole-rig draw that only 13,005Wh answers. That's the shape of need the Apex is for: not a single hard night, which the smaller box handles fine, but a daily demand that outruns 2,560Wh before you can recharge.
8-Hour Blackout: F2600 finishes at 76% used with 531Wh left, and both units survive the nightRemote Workday: F2600 finishes at 42% used with 1,266Wh to spareVan Life Daily: F2600 is 2,509Wh short of the 4,685Wh needed, its only outright failure of the six
Why it mattersIf you can't point to a day that regularly needs more than about 2,560Wh, the Apex's extra capacity is insurance against a scenario you don't actually have.
weight
The F2600's 70.5 pounds is a real lift, heavier than a packed checked suitcase, but it's a one-person, bent-knees lift that still fits in a trunk. This configuration bolts two B500K batteries onto the Apex base an owner already couldn't get onto a tableB4, so any use case where the box leaves one spot belongs to the Anker by default.
F2600: 70.5 poundsApex 300 + two B500K: 282.2 pounds, a 212-pound gapa genuine owner reports the base Apex is so heavy they can hardly carry it a few feet and couldn't lift it onto a tableB4
Why it mattersIf the unit will ever move, driveway to campsite or garage to truck, the F2600 is the only one of the two you can relocate without a second person; the Apex is home- or RV-fixed.
The specific dimensions that decide these two units — everything else is a tie.
Portability & Form Factor
Selected because: The two units weigh 70.5 and 282.2 pounds; whether you'll ever move it settles most of this before capacity is even counted.
weight
Start here, because it settles half the arguments. The Apex weighs 282.2 pounds; the F2600 weighs 70.5. That 212-pound gap isn't a portability footnote, it's the difference between a battery you own and a battery you install. One owner said the base Apex was so heavy they could barely carry it a few feet and couldn't get it onto a tableB4, and this configuration adds two more batteries to that base. The F2600 is no featherweight either, heavier than a packed checked suitcase, but it's a lift one person makes and then sets in a trunk.
So before you weigh a single watt-hour: if the unit needs to come with you, this section already ended the contest. The Apex is a thing you wire into a spot and leave. The F2600 is a thing you carry to wherever the power went out.
Your Life, Your Pick
Selected because: The F2600 finishes five of six modeled scenarios; the split shows exactly where 2,560Wh is enough and where only the Apex's 13,005Wh will do.
The split reads three wins to two for the Apex, but look at what winning means. In the 8-hour blackout the F2600 ends the night at 76% used with 531Wh in reserve; both units survive, the Apex just survives with 9,409Wh and roughly 5.7 more nights behind it. Same story at the remote workday, where the F2600 finishes at 42% and the Apex at 8%. These aren't jobs the F2600 fails. They're jobs it finishes with less left over.
One scenario is different. Van Life Daily asks for 4,685Wh, and the F2600's 2,176 usable watt-hours come up 2,509Wh short, about 47% of the day covered. That's the real dividing line: a daily draw big enough to drain 2,560Wh before you can refill it. If your life looks like that, a 50A rig or a house running for days, the Apex isn't overkill, it's the only one of the two that finishes. If it doesn't, you're buying for a night you'll never have.
Lifetime Value
Selected because: At about 43 cents against 42 per watt-hour, the five-times price is capacity rather than premium, which reframes what the money actually buys.
cost / lifetime kWh
The five-times price tag hides something the sticker doesn't say: per watt-hour, these two cost almost the same. The F2600 works out to about 43 cents a watt-hour, the Apex to about 42. You are not paying a premium for the big system, you are paying for five times the capacity at the same rate. Read that once and the value question is closed; everything left is about how many watt-hours you actually need.
Over their full rated lives the gap tilts the Apex's way by a hair, 12 cents a lifetime kilowatt-hour against 14, on the strength of 3,500 rated cycles to the F2600's 3,000. It's real and it's tiny, and it only shows up if you cycle a 282-pound battery hard for the better part of a decade. Don't let two cents decide a five-thousand-dollar purchase. The capacity question already did.
Growth Path
Selected because: The F2600 expands to 4,608Wh, a bridge that can beat jumping to the Apex, but one that still tops out well below 13,005Wh.
solar input
Both units grow, which quietly hands the F2600 an escape hatch. If your worry is that 2,560Wh might not be enough, the F2600 expands to 4,608Wh with a BP2600 batteryA2, nearly double, without leaving the portable class or the $1,100 neighborhood by much. For a lot of the might-need-more-someday buyers, that bridge is the whole answer and the Apex never enters the picture.
But be clear about the ceiling: 4,608Wh still isn't 13,005. If you already know your need is Apex-scale, expanding the Anker won't carry you there, and the Apex's higher solar ceiling of 2,400W against 1,000W means it refills a bigger bank faster off-grid. Expansion saves the buyer who's close to the F2600's line. It doesn't rescue the one who needs five times its capacity.

Weekend Camping
Two nights off-grid with essential comfort
SOLIX F2600
The Apex has five times the capacity and it's staying home; 282 pounds doesn't come camping. So this one is the F2600's by walkover, and it covers the 2,100Wh anyway, though only just: 97% used, 76Wh to spare. Bring a way to recharge if you're out more than a night.

8-Hour Blackout
Keep the essentials running through a night without power
Apex 300 + 2×B500K
Both units get you through the night. The F2600 ends at 76% used with 531Wh in reserve; the Apex ends at 15%, with 9,409Wh and roughly 5.7 more nights behind it. Tonight isn't the question. Whether your outage runs into tomorrow is, and that's the Apex's win.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
A CPAP sips about 40W, so both coast: 15% used on the F2600, 3% on the Apex. Capacity decides nothing here. Noise would, except only the Apex puts a number on it, 45dB, and that's a best-case floor, while the F2600 publishes none at all. If it's running by your pillow, this is a coin flip you settle by ear, not by spec sheet.

The Apex 300 + 2×B500K at 282.2 lbs is not a take-along — it rolls off a truck bed if it travels at all, so this scenario belongs to the SOLIX F2600 by default — and it earns it, covering the 670Wh with 1,506Wh to spare. Capacity was never the Apex 300 + 2×B500K's problem here; getting to a tailgate was.

Conclusion
August 30, 2026
Verdict: the Anker SOLIX F2600
Buy the F2600 unless you can name a load that regularly breaks 2,560Wh in a day and a fixed spot to park 282 pounds. At about 43 cents a watt-hour against the Apex's 42, you pay nearly the same rate for capacity either way, so the five-times price isn't a premium, it's five times the watt-hours, most of which a single-unit buyer never touches. The F2600 finishes five of our six scenarios, including the 8-hour blackout at 76% used; the Apex only pulls decisively ahead when the need runs multi-day or whole-rig, like the Van Life draw where the F2600 comes up 2,509Wh short. If that describes you, a 50A rig or a house down for days, the Apex is the right call and the cheaper watt-hour besides. For everyone else it's $5,399 against $1,100 and 212 more pounds for headroom you'll watch go unused.

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 F2600 rates 4.0/5 (40th percentile of 26 Large-class units), and Apex 300 + 2×B500K rates 3.5/5 (14th percentile of 29 Whole-Home / Off-Grid-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.
212 pounds decides more than any spec here
The F2600 is 70.5 pounds, the Apex 282.2, a 212-pound gap that's really a category gap. One is a battery you carry to the problem; the other is a battery you wire in once and leave. Neither is grab-and-go, but only one is a two-person, don't-do-it-on-the-stairs install. If the unit ever has to move, this is the whole decision.
45dB is a running fridge, and it's the floor, not the ceiling
The Apex's published 45dB is roughly a refrigerator's hum, but read it as a best-case figure: it's the light-load, quiet-mode number, and the fans get louder as the load climbs. Fine for a garage or a living room. For a bedroom, treat 45dB as the good case, not the sound you'll hear under load at 2 a.m.
The Apex has the surge headroom, but nothing here used it
The Apex's inverter surges to 7,680W against the F2600's 2,800W, a 2x ratio to 1.2x, the kind of margin that swallows a fridge or AC compressor's startup spike. Worth knowing, and worth being honest about: in every scenario we modeled, both units started the peak load without trouble. The extra surge is real insurance for big motors and power tools, not something the smaller unit tripped over here.
UPS Switchover: ≤10ms vs ≤20ms
Both list a UPS mode, at different rated speeds. The Apex 300 + 2×B500K is rated ≤10ms — quick enough on paper that desktop PCs and routers should ride through, treating that as the rating it is. The SOLIX F2600 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.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here. The Apex 300 + 2×B500K's figure is a maximum rather than a guarantee — it depends on buying direct from BLUETTI or registering the unit, since reseller purchases carry a shorter term. Worth saying because the per-dollar framing can suggest otherwise: the SOLIX F2600 works out at 4.5 years of cover per $1,000 spent against the Apex 300 + 2×B500K's 0.9, but that spread is the price gap, not the terms.
Battery Lifespan in Real Years
The Apex 300 + 2×B500K 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 13,005Wh on the Apex 300 + 2×B500K and 2,560Wh on the SOLIX F2600, so count lifetime energy — roughly 78,029 kWh against 7,680 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 F2600's missing noise spec isn't a verdict
Anker doesn't publish a decibel figure for the F2600. That isn't evidence it's loud, it's evidence you can't compare the two on paper at all. The Apex's 45dB is the only published number on the table, and it's a spec-sheet floor rather than a measurement. If quiet matters, this is a hear-it-yourself decision, not a spec-sheet one.

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 anywhere, full LFP across the line, and dual-voltage 120V/240V in the flagships, which is part of why the Apex is the clean way to buy big.
Worth knowing
On a $5,399 purchase, the support inconsistency is the real risk. Buy direct, register, and keep your paperwork. The app is excellent, 4.5 out of 5 on both platforms.
Analyst note
Both are value-positioned brands with a support asterisk, shaped differently: Anker is sliding from an excellent baseline, BLUETTI has been erratic from the start. Neither should scare you off, but on a five-thousand-dollar Apex the buy-direct-and-register advice isn't optional. On the $1,100 F2600, the price of a bad support day is a fifth as high.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
Anker SOLIX F2600
Field coverage for the F2600 is solid and consistent. Owners praise its inverter power, quiet operation and the app, the main nit being cable routing that could be more space-efficientA3. HyperFlash charging is a repeated standout, roughly 0 to 80% in about 78 minutesA1, and the InfiniPower LFP pack's rated 3,000 cycles with a 5-year warranty gets specific praise for outage dutyA4. Expansion to 4,608Wh via the BP2600 module is well-documentedA2. This is a known quantity.

BLUETTI Apex 300 + 2×B500K
The Apex 300 with two B500K batteries is the opposite: genuine long-term field data on this exact bundle is very thin, because it's a recent, niche configurationB0. Most of what exists tests the Apex 300 with the older B300K battery rather than the B500K, so treat it as character, not specB0. What's consistent across those reviews is the weight, one owner could barely move the base unitB4, and a design catch: reviewers repeatedly flag no built-in DC or USB ports on the face, and a roughly $300 Hub D1 accessory you add to get themB2B6.
The one verified B500K owner bought the pairing to power a 50A fifth-wheelB10, which is exactly the use case where this system makes sense. Nobody has reported back yet on multi-month longevity or cold-weather behavior for this configurationB0, so if either matters to you, you're an early adopter here.
“Some units sound like small jet engines under load, but the Apex 300's fans are relatively tame.”

“Not having DC or USB ports on the face is a tradeoff. The Hub D1 solves the problem—but it's an additional $300 accessory that you then have to bolt on after the fact.”

Who Should Buy Which
Buy the SOLIX F2600 if you…
- →The one-battery household that wants a real backup and a camp-or-tailgate power source in the same box. It carries to the driveway, runs a blackout to 76% and keeps a reserve, and one person moves it.
- →Anyone whose honest daily or outage draw sits under about 2,560Wh. You spend $1,100 instead of $5,399 and never once notice the ceiling.
- →The buyer who might need more later but not now. Start here and add a BP2600 to reach 4,608WhA2 if the day comes, rather than pre-paying for capacity you're only guessing at.
Buy the Apex 300 + 2×B500K if you…
- →The 50A RV or fifth-wheel owner. The one verified B500K owner bought it for exactly thatB10, and a 13,005Wh bank fixed in the rig is the job it was built for.
- →Whole-home backup measured in days, not hours. If your outages run long and you've got a permanent spot with room for up to 2,400W of solar, the Apex refills a big bank fast and delivers energy at 12 cents a lifetime kilowatt-hour.
- →The buyer who'd otherwise line up five portables. One integrated 240V system beats five separate boxes and five chargers for about the same money.
If neither fits
If you need portable power under about 1,000Wh, a phone-and-laptop weekender or a CPAP and a fan, both of these are too much unit. A 500-to-1,000Wh portable is a fraction of the F2600's weight and price and does that job better. And if you're cross-shopping these two purely on price, stop: they're different tools, and the cheaper one is only a bargain if 2,560Wh is actually enough for you.
The Bottom Line
The whole decision fits in one line: you pay the same rate per watt-hour either way. So the Apex's price isn't a premium, it's capacity, five times as much of it wrapped in 282 pounds that never leave the room. The only question that survives that math is whether your loads actually need 13,005 watt-hours or whether 2,560 you can carry is plenty.
For most people it's the F2600. It finishes the blackout, the workday, the campsite and the tailgate, one person lifts it, and it costs $1,100. Buy the Apex when you can name the load that breaks 2,560Wh in a day and the fixed spot to keep it, a 50A rig or a house down for days, because there it's the only one of the two that finishes, and the cheaper watt-hour besides. Size to the need in front of you, not the one you're afraid of.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the BLUETTI Apex 300 worth five times the price of the Anker F2600?
Only if you need the capacity. Per watt-hour they cost almost the same, about 42 cents against 43, so the Apex isn't overpriced, it's five times the size. If your real daily or outage load fits under 2,560Wh, paying $5,399 against $1,100 buys watt-hours you won't use. If you need around 13,000Wh for an RV or multi-day home backup, it's the right buy and slightly cheaper per lifetime kilowatt-hour.
Can you actually move the BLUETTI Apex 300 with B500K batteries?
Not easily. The configuration weighs 282.2 pounds, so it's a two-person install that stays where you put it. One owner said they could barely carry the lighter base unit a few feet. Treat it as fixed home or RV equipment, not something you relocate. The 70.5-pound F2600 is the one you can actually pick up.
Will the Anker F2600 run a house during a power outage?
For a normal evening, yes. In our 8-hour blackout model it covers the load and ends at 76% used, with reserve to spare. Where it runs out is multi-day or whole-home-for-days demand: a 4,685Wh daily draw leaves it about 2,509Wh short. For a single hard night the F2600 is plenty; for days on end you want the Apex's 13,005Wh.
Which one is quieter for a bedroom or CPAP?
Impossible to say cleanly. The Apex lists 45dB, about a running fridge, but that's a best-case floor rather than a measurement, and it climbs louder under load. The F2600 doesn't publish a noise figure at all, which isn't proof it's loud, just that there's nothing to compare it against. If it's running next to your bed, hear one before you commit.
Does the Anker F2600 expand, and is that enough to skip the Apex?
It expands to 4,608Wh with a BP2600 battery module, nearly double its 2,560Wh base. For buyers who might outgrow the base unit, that's often a smarter move than jumping to a system five times the size. It won't reach the Apex's 13,005Wh, though, so if you truly need that much, expansion won't bridge the gap.
