Head-to-head test
BLUETTI AC240P vs BLUETTI Apex 300
The Apex 300 beats the AC240P on every number that matters — more capacity, more output, a lower cost per lifetime kWh, and $140 cheaper — the only thing the AC240P wins is an IP65 rating that lets it live somewhere the Apex 300 can't.

Spec deltas
The Apex 300 costs $140 less than the AC240P and delivers 921.8Wh more capacity — 2,764.8Wh against 1,843Wh — which alone would settle most comparisons.
It backs that up everywhere else too: 3,840W continuous output against the AC240P's 2,400W, 7,680W of Power Lifting against 3,600W, and a cost per lifetime kWh of $0.11 against $0.30. The AC240P's answer is a feature the Apex 300 simply doesn't have — IP65 water and dust resistance, tested and confirmed in real rain and saltwater spray.
If you need a power station that lives on a boat deck or in an open truck bed through weather, that one spec changes the calculus. If it's living indoors, in an RV, or under any kind of cover, the Apex 300 is more capacity, more output, and less money.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
That gap shows up directly in the scenarios that matter most: Weekend Camping needs 2,100Wh, which the AC240P can't supply at all (134% of its capacity) while the Apex 300 covers it at 89% with room left. Same story on an 8-Hour Blackout — the AC240P needs 105% of its capacity and comes up short, the Apex 300 needs 70% and clears it.
AC240P capacity is 1,843Wh; Apex 300 capacity is 2,764.8WhAC240P costs $1,939; Apex 300 costs $1,699
Why it mattersAnyone comparing these two on price alone is already choosing wrong — the cheaper-looking unit is the more expensive one per watt-hour, and it fails scenarios the pricier-looking one passes.
But that protection only holds with the port covers closedA1 — plug in a cable and the rating stops applying, so it protects the unit sitting idle in weather, not the unit actively running a load in weather.
AC240P is IP65 rated; Apex 300 has no listed IP ratingAC240P survived a 6-hour rainstorm with a bone-dry interior and constant saltwater spray on a sailboat with no moisture intrusionA2
Why it mattersBuy the AC240P specifically for the scenario where the unit sits exposed and unattended — a boat, an open job site, storm prep — not as a general hedge against rain that you'd also solve by putting either unit under a tarp.
continuous output
A fridge or AC compressor can pull 2–3x its rated draw for the first second of startup; and BLUETTI publishes no surge peak for either unit, so the only number to size that spike against is the continuous rating. There the Apex 300's 3,840W is the deeper margin.
AC240P: 3,600W of Power Lifting on 2,400W continuous, no surge peak publishedApex 300: 7,680W of Power Lifting on 3,840W continuous, no surge peak published
Why it mattersIf either unit is starting a compressor appliance from a cold start, size it against the continuous rating, where the Apex 300 has 1,440W more to give; read the Power Lifting figures as heater and kettle ceilings, nothing else.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: AC240P fails two scenarios outright that the Apex 300 clears with margin.
The AC240P can't cover Weekend Camping or an 8-Hour Blackout on its own — it needs 134% and 105% of its capacity respectively, both over the line. The Apex 300 clears the same two scenarios at 89% and 70%.
Both units handle CPAP Overnight, Remote Workday, and Tailgate Party comfortably, and neither can cover full Van Life Daily use alone. The real separation happens exactly where it matters most: overnight and multi-day scenarios, not the small stuff.
Lifetime Value
Selected because: Cost-per-kWh gap is wide and driven by cycle life as much as by the capacity/price difference.
$0.30 per lifetime kWh for the AC240P against $0.11 for the Apex 300 is a wide gap, and it's driven by cycle life as much as capacity — the Apex 300 is rated for 6,000 cycles against the AC240P's 3,500, so it delivers far more watt-hours per dollar even before the $140 price difference is counted.
The AC240P does carry a longer 6-year warranty against the Apex 300's 5, which softens the math slightly, but not enough to close a $0.19-per-kWh gap.
What the Specs Don't Tell You
Selected because: Continuous output and UPS speed both fire as real advantages for the Apex 300.
rated cycles
Two real advantages for the Apex 300 here: its 3,840W continuous rating against the AC240P's 2,400W, which is the number a compressor's start has to fit under since neither unit publishes a surge peak, and its transfer switchover is faster at 10ms against the AC240P's 15ms — the difference between a UPS that catches a power blip and one that's merely fast.
Neither is dramatic on its own, but stacked with the capacity and price gap, they're one more reason the AC240P's case rests almost entirely on its weatherproofing.
Growth Path
Selected because: Both expandable, but solar ceiling differs meaningfully.
solar input
Both units are expandable, so neither locks you out of adding capacity later. The real difference is charging headroom: the Apex 300 accepts up to 2,400W of solar against the AC240P's 1,200W, so an expanded setup refills twice as fast under the same sun.
For anyone building toward a larger off-grid system, that solar ceiling compounds — it's not just more battery later, it's a faster recharge on whatever you eventually add.

Apex 300
The AC240P doesn't finish — 1,567Wh usable against the 2,100Wh this needs leaves it 533Wh short, about 75% of the scenario covered. The Apex 300 covers it with 250Wh to spare.

8-Hour Blackout
Keep the essentials running through a night without power
Apex 300
The AC240P comes up just short — it needs 1,645Wh and has 1,567Wh usable, a 78Wh gap (its nameplate 1,843Wh actually clears this — the flat 15% conversion allowance is what tips it under). Trim that much — one small appliance's worth across the day — and it finishes. The Apex 300 covers it outright with 705Wh 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 of these cover the night several times over — capacity isn't the question here. Both happen to list 45dB — the same published figure twice, not a measured tie — so there is nothing in the noise column to separate them either. Only the Apex 300 is still sold, so a new purchase here is just the Apex 300; the AC240P is a used-market question.

Apex 300
The Apex 300 clears the workday at 39% used, banking 1,440Wh — late work, extra calls, or a second laptop charge without arithmetic. The AC240P at 58% also finishes, with 657Wh of slack for the unplanned.

Apex 300
Both handle game day; the Apex 300 keeps more in reserve (29% used vs 43%). Tailgating is a light load, though, so the number you'll feel is weight: 72 lbs for the AC240P against 83.8 lbs for the Apex 300, from the trunk to the setup spot.

Conclusion
November 1, 2026
Verdict: the Apex 300, on Power Score margin
The Apex 300 wins on nearly every axis: 2,764.8Wh against the AC240P's 1,843Wh, 3,840W continuous against 2,400W, and a $140 lower price at $1,699 against $1,939. Its cost per lifetime kWh comes in at $0.11 against the AC240P's $0.30 — a real gap that compounds every time either unit is cycled. The AC240P's one genuine advantage is IP65 weatherproofing, verified in real rainstorms and saltwater spray — a feature the Apex 300 doesn't have at all. Unless you specifically need that rating, the Apex 300 is the better buy at a lower price.
Today the Apex 300 is $1,599, $100 under its typical $1,699. The verdict weighs typical prices, not today's. Prices checked 28 days ago.

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, AC240P rates 3.9/5 (35th percentile of 27 Everyday-class units), and Apex 300 rates 4.9/5 (93rd percentile of 28 Large-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
Weight Reality Check
Neither unit is grab-and-go. The AC240P (72 lbs) is manageable solo but heavier than a large checked suitcase. The Apex 300 (83.8 lbs) is noticeably heavier. That's a 12 lb difference.
Fan Noise: Line Ball
Both units are rated at the same 45dB — like a running refrigerator. One published figure, twice, so noise shouldn't decide this one.
Power Lifting: 3,600W and 7,680W
Both units have BLUETTI's Power Lifting mode: the AC240P to 3,600W on a 2,400W inverter, the Apex 300 to 7,680W on 3,840W. It works by delivering less power than the appliance asks for rather than more than the inverter has, so the appliance runs slower rather than not at all. BLUETTI scopes the mode to purely resistive loads — a heater, a kettle, an incandescent lamp — so it does nothing for a fridge compressor, a pump or a power tool. Neither record publishes an instantaneous surge figure, so nothing on this card speaks to motor loads. Judge the Lifting figures on which ceiling covers the resistive load you actually own.
UPS Switchover: ≤10ms vs ≤15ms
Both list a UPS mode, at different rated speeds. The Apex 300 is rated ≤10ms — quick enough on paper that desktop PCs and routers should ride through, treating that as the rating it is. The AC240P is rated ≤15ms — 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: 6 Years vs 5
The AC240P is covered for 6 years against the Apex 300's 5 years. The Apex 300'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. An underrated factor if you're keeping this unit for years.
Battery Lifespan in Real Years
The Apex 300 is rated for 6,000 cycles vs 3,500. In real life: at daily use, that's 16.4 vs 9.6 years. At weekend use (twice a week), it's 58 vs 34 years. One caution reading years across different sizes: a cycle is 2,765Wh on the Apex 300 and 1,843Wh on the AC240P, so count lifetime energy — roughly 16,589 kWh against 6,451 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.

Analyst note
The AC240P is no longer sold, so there is no price to work its cost per kWh from, and this comparison doesn't quote one. On what you can actually buy today, the Apex 300 works out at $0.10/kWh over its rated life. If you already own the AC240P, the hardware comparison still holds: over its rated life the AC240P delivers about 6,451 kWh and the Apex 300 about 16,589 kWh.

Analyst note
Growth only counts if you can still buy in, and the AC240P is no longer sold (BLUETTI points owners to the AC200L). That leaves the Apex 300: it starts at 2,765Wh and takes BLUETTI expansion batteries, so the ceiling moves if your needs do. The AC240P's expandability still matters if you already own one, but it isn't a reason to pick it over the Apex 300.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
BLUETTI AC240P
The AC240P's field reputation is almost entirely about weatherproofing, and it holds up. One review left it outside through a 6-hour rainstorm and found the interior bone dry, and another ran it on a sailboat through constant saltwater spray with no moisture intrusion after a wipe-downA2. The one caveat worth knowing: that IP65 protection only applies with the port covers closed — plug in a cable and you've compromised the seal, so it doesn't protect the unit while it's actively running exposed to rainA1.
Reviewers frame the AC240P as the premium, higher-capacity option in BLUETTI's IP65 line, 307Wh above the standard AC240, with fast charging and expansion to a large multi-kWh bankA3A4 — solid credentials, just built around a different priority than raw capacity per dollar.
“IP65 water- and dust-resistant, but the protection applies only when all port covers are closed; using it with cables plugged in compromises the rating, and it shouldn't be used in the rain that way.”

BLUETTI Apex 300
Port complaints dominate the Apex 300's owner feedback. It ships with no built-in USB or DC ports, and reviewers call the required $300 Hub D1 accessory steep for what it deliversB7B11; connecting multiple units needs a separate $699 Hub A1 Parallel BoxB12. Firmware has also caused real friction — forum posts describe an update locking the unit into 'Backup' modeB1 and another triggering an Error 004 charging faultB2.
On the physical side, weight is the honest complaint: one reviewer says he could hardly carry it a few feet at a time and never got it onto a table aloneB8, though another calls it manageable thanks to the handles and modular designB6. Fan noise, at least, tested better than expected — relatively tame under load rather than the small-jet-engine sound some rival units produceB5.

Who Should Buy Which
Buy the AC240P if you…
- →Anyone who needs the unit to sit exposed to weather unattended — a boat deck, an open job site, storm-adjacent outdoor use — where the IP65 rating (with covers closed) is the deciding factor.
- →Buyers who specifically value the AC240P's 6-year warranty over the Apex 300's 5-year term and can live with less capacity.
Buy the Apex 300 if you…
- →Anyone comparing these two on price who assumed the cheaper number meant less unit — it's actually more capacity, more output, and a lower cost per lifetime kWh.
- →Buyers who need Weekend Camping or an 8-Hour Blackout actually covered rather than theoretically close — the AC240P falls short on both.
If neither fits
Full-time off-grid users needing Van Life Daily-scale power (4,685Wh) should look elsewhere — the AC240P needs 299% of its capacity and the Apex 300 needs 199%, and neither number is survivable from a single unit.
The Bottom Line
Take the Apex 300 unless the unit specifically needs to survive rain or saltwater spray while sitting exposed — it beats the AC240P on capacity, output, and cost per lifetime kWh, for $140 less.
The AC240P isn't a worse power station; it's a specialist. Buy it for the IP65 rating, not for anything else on the spec sheet.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the BLUETTI AC240P worth the extra $140 over the Apex 300?
Only for its IP65 weatherproofing. The Apex 300 has more capacity (2,764.8Wh versus 1,843Wh), more output, and a lower cost per lifetime kWh ($0.11 versus $0.30) for $140 less. The AC240P's case rests almost entirely on surviving rain and saltwater exposure that the Apex 300 isn't rated for.
Does the AC240P's IP65 rating work while it's plugged in and running?
Not fully. The rating applies when the port covers are closed, and using it with cables plugged in compromises that seal. It's rated to sit exposed to weather while idle or between uses, not to run a load in active rain.
Can the AC240P handle a full weekend of camping power?
Not on its own — a typical Weekend Camping load of 2,100Wh is 134% of its 1,843Wh capacity. The Apex 300 covers the same load at 89% of its larger 2,764.8Wh battery, with margin to spare.
Which one starts a fridge or AC compressor more reliably?
The Apex 300, on paper, because its 3,840W continuous rating leaves more room under it than the AC240P's 2,400W. Neither unit publishes a surge peak. The 7,680W and 3,600W figures are Power Lifting, a mode for running resistive heaters and kettles above the inverter's rating, and BLUETTI scopes it to resistive loads, so it does nothing for a compressor.
Is the Apex 300 too heavy to be a practical upgrade?
At 83.78 lbs it's a genuine handling consideration — one reviewer couldn't lift it onto a table alone. It's the more awkward of the two to move often, which is worth weighing against the AC240P's 72 lbs even though the AC240P loses on nearly every other spec.
