Spec deltas
Both carry the BLUETTI name, but they're built for different buyers. The AC240P (1,843Wh, 2,400W) and the FridgePower (2,016Wh, 1,800W) come from different product lines with different engineering priorities and a $563 price gap. We'd buy the FridgePower.
The FridgePower holds 173Wh more than the AC240P — about 11 hours on a fridge against 10 — a real but modest edge that shows up mainly on longer outages. For camping, tailgating, or keeping devices charged, both have the headroom, so price, weight, and longevity lead the decision instead.
Pick the FridgePower if your primary use is 8-hour blackout. Go with the AC240P if you want the option to add expansion batteries later. 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
- +Higher AC output
- +Longer warranty
- +Faster solar charging
Trade-offs
- –Significantly heavier (+28.6 lbs), making it harder to move.
BLUETTI FridgePower
The 1,800W inverter handles most daily devices like laptops, blenders, and TVs, but will struggle with heating elements that require over 1500W. A standout feature is the value proposition: at roughly $0.45 per watt-hour, it's one of the most cost-effective options on the market.
Strengths
- +Lighter by 28.6 lb
- +Larger battery capacity
Trade-offs
- –Weaker inverter (-600W) limits appliance compatibility.

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 FridgePower 386Wh (81%). Either gets you most of the way, so this is a scenario you plan around rather than one you should rule them out for.

SCN-02 · 8 hours · needs 1,645Wh
8-Hour Blackout
Keep the essentials running through a night without power
FridgePower
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 FridgePower covers it outright with 69Wh to spare.

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 several times over — capacity isn't the question here. The only published difference is fan noise, and it can't settle this: the AC240P is rated 45dB and the FridgePower 50dB, but both are BLUETTI's own ratings on one convention, best-case floors rather than readings at a CPAP's draw. Neither settles which box is quieter at a bedside. Only the FridgePower is still sold, so a new purchase here is just the FridgePower; 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
Either unit
Both power your workstation all day without strain. The AC240P lists 100W of USB-C for direct laptop charging; the FridgePower carries no USB-C at all, so a laptop there goes through the inverter and you are carrying its brick.
Battery budget usedlower = more headroom

Tailgate Party
Game day power for the crew
Either unit
Both handle game day easily. Since capacity isn't the deciding factor, weight is: at 43.4 lbs the FridgePower is the one you'll be glad you brought. Fan noise under load is worth a listen too — it's audible in the lulls between songs.

Neither unit
Neither unit covers this scenario's 4,685Wh: the AC240P comes up 3,118Wh short (about 33% covered), the FridgePower 2,971Wh (37%). Treat this as partial cover — enough for the essentials in it, not the whole list.

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 FridgePower rates 3.5/5 (12th percentile of 26 Large-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: Two Published Ratings
The AC240P is rated 45dB (like a running refrigerator), the FridgePower 50dB (like moderate rainfall). Neither is a measurement on a shared bench — both are BLUETTI's own ratings on one convention, best-case floors rather than readings at a CPAP's draw. Take the pair as a prompt to find hands-on reports rather than as a gap you can act on. For most people, fan noise around 45dB and up is where sleep starts to suffer, and neither figure tells you what either unit does at a 40W draw.
Power Lifting: 3,600W and 3,000W
Both units have BLUETTI's Power Lifting mode: the AC240P to 3,600W on a 2,400W inverter, the FridgePower to 3,000W on 1,800W. 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 FridgePower publishes a 3,600W 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: ≤10ms vs ≤15ms
Both list a UPS mode, at different rated speeds. The FridgePower 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 FridgePower's 5 years. The FridgePower'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 FridgePower works out at $0.11/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 FridgePower about 8,064 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 FridgePower: it starts at 2,016Wh 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 FridgePower.
The Bottom Line
The full picture comes down to this. The FridgePower 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 AC240P wins in the scenarios that match your life, it's the right choice regardless of aggregate scores.
If neither the AC240P nor the FridgePower 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.
Can I actually carry the AC240P, or is the FridgePower the only portable option?
Neither is "portable" in any hiking sense. The FridgePower (43.4 lbs) and the AC240P (72 lbs) are both appliances you place and leave. The 28.6-lb difference matters when loading into a vehicle or moving between rooms, but that's about it. If true portability is your priority, look at units under 20 lbs in a different class entirely.
Bottom line: should I buy the AC240P or the FridgePower?
We'd buy the FridgePower. The AC240P is no longer sold, so there is no price to weigh it against; the comparison on this page still helps if you own one.
