Head-to-head test
BLUETTI AC240P vs BLUETTI Elite 320
For $940 less, the Elite 320 packs 1,357Wh more capacity and costs a third as much to run over its life — the AC240P earns its higher price back only if you need to start something past a 2,700W surge or want the option to expand later, because the Elite 320 can do neither.

Spec deltas
The BLUETTI Elite 320 costs $999 and holds 3,200Wh. The AC240P costs $1,939 and holds 1,843Wh — nearly double the price for 1,357Wh less. Run the ownership math and it gets worse for the AC240P: $0.30 per lifetime kWh against the Elite 320's $0.10, a third of the cost, despite the AC240P's edge in warranty (6 years against 5) and cycle count (3,500 against 3,000).
The Elite 320 also wins more of the day-to-day jobs — it clears Weekend Camping, the 8-Hour Blackout, Remote Workday, and Tailgate Party outright, where the AC240P clears only two of those with real margin. What it can't do is grow: it's a closed system, full stop, while the AC240P accepts BLUETTI's own expansion batteries.
The AC240P's other real card is surge capacity — 3,600W against the Elite 320's 2,700W — which matters the moment either unit has to start a compressor fridge rather than just run one.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
That holds even though the Elite 320 is rated for fewer cycles, 3,000 against 3,500. The AC240P's extra 500 cycles aren't enough to close a gap this size, because they're stacked on top of a sticker price that's already $940 higher.
The Elite 320 costs $999 for 3,200Wh; the AC240P costs $1,939 for 1,843WhThe Elite 320's lifetime cost is $0.10 per kWh against the AC240P's $0.30
Why it mattersA buyer choosing purely on price-per-kWh should take the Elite 320 without a second thought — cycle count isn't the variable doing the work here, price is.
continuous output
A 900W surge gap is the difference between a heavy fridge or AC compressor starting cleanly on the AC240P and tripping the Elite 320's inverter on the same device, especially for anything already running close to 1,800W continuous.
AC240P outputs 2,400W continuous with a 3,600W surgeElite 320 outputs 1,800W continuous with a 2,700W surge
Why it mattersAnyone planning to run a compressor appliance off either unit — an RV fridge, a window AC, a chest freezer — should size against surge, not capacity, and that favors the AC240P.
Since the Elite 320 is already $940 cheaper, growing past its ceiling means buying an entire second unit at whatever it costs by then. The AC240P's expansion batteries add capacity onto the unit you already own without replacing the base station.
The AC240P accepts BLUETTI's own expansion batteriesThe Elite 320 has no expansion path — what you buy is the ceiling
Why it mattersAnyone whose power needs might grow over the next few years — more gear, longer trips, a partial home-backup buildout — should weigh the AC240P's open architecture over the Elite 320's lower starting price.
Noise tells the opposite kind of half-story: BLUETTI states 45dB under load for the AC240P but hasn't published a figure for the Elite 320 at all, so the unit you'd actually wheel into a bedroom overnight is the one with no published answer to how loud it gets while charging.
Elite 320 weighs 74.96 lbs but ships with oversized shock-absorbing wheels and a telescoping handleB2AC240P weighs 72 lbs with no wheeled cart mentioned
Why it mattersAnyone moving this thing around the house daily should weigh the Elite 320's wheels over its raw weight number; anyone sensitive to fan noise should ask BLUETTI directly before buying either.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: The Elite 320 beats the AC240P on price, capacity, and cost-per-kWh simultaneously — the core story.
cost / lifetime kWh
The Elite 320 costs $940 less and still holds 1,357Wh more. Run both to the end of their rated cycle life and the AC240P delivers about 6,451 kWh for $1,939; the Elite 320 delivers about 9,600 kWh for $999 — more total energy for roughly half the money.
Cost-per-warranty-year adds a smaller point on top of the big one: $323 a year on the AC240P's 6-year term against $200 a year on the Elite 320's 5-year term. The AC240P's extra year of coverage and extra 500 rated cycles are real, they just don't come close to closing a gap this size.
Your Life, Your Pick
Selected because: Elite 320 clears four of six modeled jobs against the AC240P's two — worth showing directly.
The Elite 320 clears four of six modeled jobs outright — Weekend Camping, the 8-Hour Blackout, Remote Workday, and Tailgate Party — while the AC240P clears only the lighter two with real margin and fails the first two at 134% and 105% of its usable capacity. CPAP Overnight is the one true tie, both units spending well under a quarter of their tank on it.
Van Life Daily is out of reach for both, at 299% and 172% of what's needed — that's a job for a larger system than either of these, not a reason to choose between them.
What the Specs Don't Tell You
Selected because: No expansion path and no published noise rating are the Elite 320's real, concrete catches.
rated cycles
The Elite 320's real catch is no expansion path at all — what ships is the ceiling, permanently. Weight is close enough not to matter on its own (72 lbs against 74.96), but the Elite 320 ships with oversized wheels and a telescoping handle, so the technically heavier unit is actually the easier one to move around a houseB2.
Noise is unresolved rather than a wash: BLUETTI discloses 45dB under load for the AC240P but hasn't published a figure for the Elite 320. UPS switchover favors the Elite 320, 10ms against 15ms, and its 140W USB-C port beats the AC240P's 100W — small conveniences that don't move the bigger decision.
Growth Path
Selected because: The AC240P's one clear structural win over a cheaper, bigger-capacity sibling.
solar input
This is the AC240P's clearest structural win. It accepts BLUETTI's own expansion batteries, so a power need that outgrows 1,843Wh gets solved by adding a pack, not replacing the unit. The Elite 320 is a closed system — outgrow 3,200Wh and the fix is an entirely new purchase, at whatever the Elite 320 costs by then.
That flexibility has real dollar value for anyone whose needs might grow — more camping gear, longer trips, a partial home-backup buildout. For anyone confident 3,200Wh is enough for good, the Elite 320's much lower price makes the AC240P's growth path a feature you're paying for and not using.

CPAP Overnight
Sleep therapy without interruption — the #1 medical use case
Either unit
Both are wildly overqualified for CPAP. You're using 20% or less. Save your money and buy whichever is cheaper; the extra capacity is completely wasted on a 40W overnight load. Put the savings toward a second battery for multi-night trips.

Elite 320
Both handle game day, and the Elite 320 does it with more in reserve — 25% used against 43%. Tailgating is a light load, so that headroom counts for less here than the 3 lbs you'll actually carry across the parking lot.

Conclusion
July 15, 2026
Verdict: the Elite 320
Buy the Elite 320 unless you specifically need surge headroom or a growth path. At $999 it's $940 cheaper than the AC240P, holds 1,357Wh more (3,200Wh vs 1,843Wh), and costs $0.10 per lifetime kWh against the AC240P's $0.30 — despite the AC240P's edge in cycle count and warranty length, the price gap swamps it. The Elite 320 also clears four of six modeled scenarios outright where the AC240P clears only two with real margin. What it gives up is real: no expansion path at all, a 2,700W surge ceiling well short of the AC240P's 3,600W, and no published noise rating. If you're starting a heavy compressor appliance or want the option to add capacity later, that's the AC240P's lane — everyone else should keep the $940.

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 4.2/5 (52nd percentile of 24 Everyday-class units), and Elite 320 rates 3.9/5 (38th percentile of 25 Large-class units).

Weight Reality Check
Neither unit is grab-and-go. The AC240P (72 lbs) is manageable solo but heavier than a large checked suitcase. The Elite 320 (75 lbs) is noticeably heavier. That's a 3 lb difference.
AC240P: 45dB Under Load
45dB is about as loud as a running refrigerator. If you're running a CPAP or sleeping near this unit, the fan noise may be noticeable. Most people find anything above 45dB disruptive for sleep.
Elite 320: No Expansion Path
What ships is what you get — 3,200Wh, permanently. If there's a real chance your power needs grow, the AC240P's open architecture is worth the extra money on its own; the Elite 320 doesn't have a path to more.
UPS Speed: line-interactive (<10ms) vs standby (<20ms)
The Elite 320 switches to battery in 10ms (line-interactive (<10ms)), while the AC240P takes 15ms (standby (<20ms)). Safe for desktop PCs, routers, and CPAP machines. NAS drives are protected. This matters if you're using it as a home UPS for always-on equipment.
Elite 320: Noise Level Not Disclosed
BLUETTI states 45dB under load for the AC240P but hasn't published a comparable figure for the Elite 320. Worth a direct question before you plan on running it near a bedroom overnight.

Analyst note
Don't read the AC240P's expandability as a straight win here: it starts at 1,843Wh, below the Elite 320's 3,200Wh, so a first expansion battery largely buys back capacity the Elite 320 already includes. It only pulls ahead if you'd grow past 3,200Wh — short of that, the Elite 320's larger fixed capacity is the simpler value.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
BLUETTI AC240P
Worth knowing upfront: the AC240P's IP65 rating only holds when every port cover is closed — plug in a cable during a storm and you've voided the protection you paid forA1. That's not a knock on the rating itself; owners who've actually tested it report water beading off in a 6-hour rainstorm with a bone-dry interior, and no moisture intrusion after weeks of saltwater spray on a sailboatA2.
This is the higher-capacity version of BLUETTI's AC240 platform, the premium end of the lineup with fast charging and room to expand into a much larger bankA4 — capability the Elite 320 simply doesn't have on this page, at a price the Elite 320 undercuts by nearly half.
“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 Elite 320
The Elite 320 launched at CES 2026 as a suitcase-style home-backup unit, and reviewers focus on the numbers behind that pitch: a 3,200Wh LiFePO4 battery good for over a decade of use, delivering up to two days of essential household power across four AC outlets and dual USB-C portsB3.
At about 75 lbs it's heavier than the AC240P on paper, but it ships with oversized shock-absorbing wheels and a telescoping handle built for moving it around the house, not just to a campsiteB2 — positioned as affordable, essential backup power rather than a rugged field unitB4.
“A 3,200Wh LiFePO4 battery delivering 1,800W continuous (2,700W Power Lifting, 3,600W peak), with 10ms UPS protection — a suitcase-style rolling home-backup station introduced at CES 2026.”

Who Should Buy Which
Buy the AC240P if you…
- →You need to start a compressor appliance — an RV fridge, a window AC — where the AC240P's surge headroom beats the Elite 320's 2,700W ceiling.
- →You want a genuine growth path: the AC240P accepts BLUETTI's own expansion batteries, and the Elite 320 flatly doesn't.
Buy the Elite 320 if you…
- →You want the most capacity and the lowest cost per kWh on this page, full stop — 3,200Wh for $999, a third of the AC240P's lifetime cost.
- →You're moving the unit around the house regularly and want wheels doing the work instead of your backB2.
If neither fits
If you're chasing van-life-daily power — about 4,685Wh a day — neither of these gets close, sitting at 299% and 172% of what's needed. That's a job for a larger stationary system, not either of these.
The Bottom Line
The Elite 320 beats the AC240P on price, capacity, and lifetime cost by a wide margin — $999 against $1,939 for 1,357Wh more capacity, at a third of the cost per kWh delivered. It also clears more of the day-to-day jobs modeled on this page.
The AC240P earns its higher price back in exactly two places: a real surge ceiling for starting heavy appliances, and an expansion path the Elite 320 doesn't have at any price. Outside those two cases, the Elite 320 is both the cheaper and the better-equipped unit.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the AC240P worth $940 more than the Elite 320?
Only for two things the Elite 320 doesn't do: a 3,600W surge for starting heavy compressor appliances, and a true expansion path. On price, capacity, and lifetime cost, the Elite 320 wins across the board — $999 for 3,200Wh at $0.10 per lifetime kWh against the AC240P's $1,939 for 1,843Wh at $0.30.
Can the Elite 320 be expanded later?
No. It's a closed system — what you buy is the ceiling, and outgrowing 3,200Wh means buying an entirely new unit. The AC240P is the only one of these two that accepts expansion batteries.
Which one starts a fridge or window AC more reliably?
The AC240P has more surge headroom, 3,600W against the Elite 320's 2,700W, which matters for the moment a compressor kicks on and briefly draws well past its running wattage.
Which is quieter, the AC240P or the Elite 320?
Unclear — BLUETTI states 45dB under load for the AC240P but hasn't published a noise rating for the Elite 320 at all. If fan noise matters, ask before buying either.
Which one should I actually buy?
Take the Elite 320 unless you specifically need to start a heavy compressor appliance or want the option to expand capacity later. For most buyers, more capacity at less than half the AC240P's lifetime cost settles this one.
