Spec deltas
Two sizes from BLUETTI's AC lineup: AC70P at 864Wh, AC240P at 1,843Wh. The $963 gap between them buys a fundamentally different tool. One you carry. One you place and leave. The AC240P has a slight edge, but the margin is close enough that your use case should break the tie.
What the spec gap means in practice: the AC240P's 2,400W inverter has the headroom for a window AC, a full-size fridge, and power tools. The AC70P's 1,000W inverter can't run the heaviest of those — a window AC or a high-surge power tool needs more than it can hold, whatever its 2,000W surge ceiling does at the instant of startup. On stamina, the AC240P keeps a fridge alive for roughly 10 hours vs the AC70P's 5 hours. The cost? Portability. At 72 lbs, the AC240P is heavy enough to make you think twice about moving it. The AC70P at 22.5 lbs is something one person can actually carry.
Pick the AC240P if your primary use is remote workday or tailgate party. Go with the AC70P if its specific strengths below line up better with your use. Keep scrolling for the full breakdown. The scenario verdicts below hold a few surprises.
Bench Notes
What each unit does well, where it falls short, and the trade-offs that matter.
BLUETTI AC240P
With a massive 2,400W output, the AC240P can run high-wattage appliances like space heaters, hair dryers, and electric grills without tripping. Weighing in at 72 lbs, this is not a unit you want to carry far. It's best suited as a stationary backup or RV companion.
Strengths
- +Larger battery capacity
- +Higher AC output
- +Longer warranty
- +Faster solar charging
Trade-offs
- –Significantly heavier (+49.5 lbs), making it harder to move.
BLUETTI AC70P
The 1,000W inverter handles most daily devices like laptops, blenders, and TVs, but will struggle with heating elements that require over 1500W. At only 22.5 lbs, it is exceptionally portable. You can easily carry it one-handed to a campsite or tailgating party. A standout feature is the value proposition: at roughly $0.58 per watt-hour, it's one of the most cost-effective options on the market.
Strengths
- +Lighter by 49.5 lb
Trade-offs
- –Weaker inverter (-1,400W) limits appliance compatibility.
- –Sealed capacity — the AC240P can add batteries to grow past 864Wh; this one can't.

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 unit covers this scenario's 2,100Wh: the AC240P comes up 533Wh short (about 75% covered), the AC70P 1,366Wh (35%). Treat this as partial cover — enough for the essentials in it, not the whole list.

LOAD Phone Charger 15W×6h · LED Lights 40W×8h · Box Fan 75W×14h · CPAP Machine 40W×16h
SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
Neither unit
This scenario needs 1,645Wh and neither unit quite finishes it. The AC240P lands within 5% of it — close enough that trimming one appliance, or accepting a shorter evening, gets you there on the day.
Battery budget usedlower = more headroom
LOAD Fridge 150W×8h · Router + Modem 20W×8h · LED Lights (4 bulbs) 40W×6h · Phone Charger 15W×3h
SCN-03 · 8 hours · needs 320Wh
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 at least twice 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 AC70P is still sold, so a new purchase here is just the AC70P; the AC240P is a used-market question.
Battery budget usedlower = more headroom
LOAD CPAP Machine 40W×8h
SCN-04 · 8 hours · needs 910Wh
Remote Workday
Full work day off-grid without power anxiety
AC240P
The AC70P doesn't finish — 734Wh usable against the 910Wh this needs leaves it 176Wh short, about 81% of the scenario covered. The AC240P covers it with 657Wh to spare.
Battery budget usedlower = more headroom
LOAD Laptop 60W×8h · External Monitor 30W×8h · Router + Modem 20W×8h · Phone Charger 15W×2h
SCN-05 · 4 hours · needs 670Wh
Tailgate Party
Game day power for the crew
AC240P
Both handle game day; the AC240P keeps more in reserve (43% used vs 91%). Tailgating is a light load, though, so the number you'll feel is weight: 22.5 lbs for the AC70P against 72 lbs for the AC240P, from the trunk to the setup spot.
Battery budget usedlower = more headroom
LOAD Blender 400W×0.5h · LED TV (55") 80W×4h · Bluetooth Speaker 15W×4h · Phone Charger (×3) 45W×2h

Van Life Daily
A full day of mobile living — the ultimate endurance test
Neither unit
Neither unit covers this scenario's 4,685Wh: the AC240P comes up 3,118Wh short (about 33% covered), the AC70P 3,951Wh (16%). This is well outside what either unit is for; the right answer here is a larger station, not a choice between these two.

Verdict withdrawn: the AC240P is no longer sold
We picked the AC240P, but it's been discontinued (BLUETTI now points buyers to the AC200L). The AC70P is still on sale, but that alone doesn't make it our pick. The comparison below is still accurate if you own either one.

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 AC70P rates 4.5/5 (68th percentile of 20 Compact-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.
AC240P: 72 lbs Is a Commitment
At 72 lbs, this is manageable but not fun to move. That's heavier than a large checked suitcase. How much it costs you depends on whether it rolls — wheels and a telescoping handle change the job completely at this weight, and our spec record doesn't track them, so look at the product photos before you plan on carrying it from the car.
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.
AC70P: Fixed Capacity
The AC70P is sealed at 864Wh, and that is the ceiling. Normally the counterpoint would be that the AC240P can add expansion batteries, but that isn't a live option here: the AC240P is no longer sold, and BLUETTI points owners to the AC200L. For a new purchase the expansion question doesn't arise between these two, so the AC70P's fixed 864Wh is simply what you get.
Power Lifting: 3,600W and 2,000W
Both units have BLUETTI's Power Lifting mode: the AC240P to 3,600W on a 2,400W inverter, the AC70P to 2,000W on 1,000W. 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. Surge is a separate figure: the AC70P publishes a 2,000W surge peak, the figure a motor's switch-on draw meets, and the AC240P's record carries none. Neither Lifting figure speaks to motor loads. Judge the Lifting figures on which ceiling covers the resistive load you actually own.
UPS Switchover: ≤15ms vs ≤20ms
Both list a UPS mode, at different rated speeds. The AC240P is rated ≤15ms — fine on paper for routers and most electronics; the fussiest PC power supplies sit right at this line. The AC70P 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: 6 Years vs 5
The AC240P is covered for 6 years against the AC70P's 5 years. The AC70P'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.

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 AC70P works out at $0.19/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 AC70P about 2,592 kWh.
Growth path
AC240P
EXPANDABLESupports BLUETTI expansion batteries, so you can add capacity later without replacing the base unit — useful if your needs may climb past 1,843Wh.
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.
Expansion batteries are BLUETTI-specific. You're investing in the BLUETTI ecosystem.
AC70P
FIXED CAPACITYFixed at 864Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.
Accepts up to 500W of solar. Suitable for a 1-2 panel setup.
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
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 AC70P: it is sealed at 864Wh, so buy the size that covers you now. The AC240P's expandability still matters if you already own one, but it isn't a reason to pick it over the AC70P.
The Bottom Line
The full picture comes down to this. The AC240P edges ahead on our overall analysis, but the margin is narrow enough that your specific use case should drive the decision. Review the scenario verdicts above — if the AC70P wins in the scenarios that match your life, it's the right choice regardless of aggregate scores.
If neither the AC240P nor the AC70P feels like the right fit, your power needs probably sit outside what these two target. Use our comparison tool above to explore alternatives that better match your specific wattage and runtime requirements. Prices on portable power stations fluctuate frequently. Both BLUETTI discount regularly, so check the current price before committing. Prime Day and Black Friday pricing typically drops 20-30%.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
How does the 979Wh capacity difference actually affect daily use?
The AC240P's 1,843Wh battery keeps a mini-fridge running for roughly 10 hours vs the AC70P's 5 hours. What specs don't mention: runtime drops 20-30% in cold weather (below 32°F/0°C) as battery chemistry slows down. The AC240P's extra capacity provides a critical cold-weather buffer. For occasional phone and laptop charging, both are overkill. This gap only matters for sustained, multi-appliance use.
Can I actually carry the AC240P, or is the AC70P the only portable option?
At 22.5 lbs, the AC70P is manageable for one person over short distances: parking lot to campsite, trunk to tailgate. The AC240P at 72 lbs? You'll want a buddy, a wagon, or wheels. For reference, 72 lbs is about the weight of a bag of concrete. If your use case involves any carrying, the AC70P wins decisively.
How fast can each unit recharge from solar panels in real conditions?
On paper, the AC240P accepts 1,200W vs the AC70P's 500W of solar input. What the spec sheet won't tell you: solar panels typically deliver only 60-80% of their rated output due to panel angle, cloud cover, and temperature. In realistic conditions, expect full recharge in about 2.2 hours for the AC240P and 2.5 hours for the AC70P. That gap widens on cloudy days, when the AC240P's higher input ceiling captures more of whatever sunlight is available. One more thing: summer gives you ~7 productive solar hours per day. Winter drops to ~4. If solar is your primary recharge method, the AC240P's advantage is substantial.
What if I need more capacity than the AC70P's 864Wh later?
The AC70P is sealed at 864Wh, so if you expect your needs to climb, the AC240P is the more future-proof pick: it starts at 1,843Wh and adds BLUETTI-compatible batteries without replacing the base unit. That said, "not expandable" isn't a flaw on its own — if 864Wh comfortably covers your loads, the AC70P is a complete unit, not a downgrade.
Bottom line: should I buy the AC240P or the AC70P?
We'd have said the AC240P, but it is no longer sold. The AC70P is still on sale, but that alone doesn't make it our pick. The comparison on this page is still accurate if you own either one.
