EcoFlow DELTA Pro vs BLUETTI AC240P
The EcoFlow DELTA Pro (3,600Wh) and BLUETTI AC240P (1,843Wh) sit in different weight classes. The real question: do your power needs justify the larger unit, or would you be overpaying for capacity that sits unused? We'd buy the DELTA Pro.
What the spec gap means in practice: the DELTA Pro's 3,600W inverter can run a window AC unit, a full-size fridge, or power tools. The AC240P's 2,400W inverter will flat-out refuse to start those appliances. On stamina, the DELTA Pro keeps a fridge alive for roughly 20 hours vs the AC240P's 10 hours. The cost? Portability. At 99 lbs, the DELTA Pro is heavy enough to make you think twice about moving it. The AC240P at 72 lbs is more manageable, though still not light.
Pick the DELTA Pro if your primary use is weekend camping or 8-hour blackout. Go with the AC240P if you need the heavier-duty specs for demanding loads. Most buyers overlook this: the DELTA Pro costs ~$0.11/kWh over its full lifespan, which adds up significantly over years of regular use. Keep scrolling for the full breakdown. The scenario verdicts below hold a few surprises.

What the Specs Don't Tell You
Hidden gotchas and advantages we spotted that you won't find on the product page.
Weight Reality Check
NoteNeither unit is grab-and-go. The AC240P (72 lbs) is manageable solo but heavier than a large checked suitcase. The DELTA Pro (99 lbs) is noticeably heavier. That's a 27 lb difference.
Fan Noise Under Load
Watch outThe AC240P runs at 45dB (like a running refrigerator), while the DELTA Pro hits 60dB (like a normal conversation). Most people find anything above 45dB disruptive for sleep. Worth considering if you're running a CPAP or camping in a tent nearby.
Surge Power: Inverter Quality Indicator
AdvantageThe DELTA Pro has a 2× surge-to-continuous ratio vs the AC240P's 1.5×. A higher ratio (≥2×) means the inverter handles motor startup surges better. That's critical for fridges, AC compressors, and power tools that briefly draw 2-3× their rated wattage. The AC240P may trip when starting these appliances even though its continuous wattage looks sufficient.
UPS Speed: standby (<20ms) vs standby (<20ms)
NoteThe AC240P switches to battery in 15ms (standby (<20ms)), while the DELTA Pro takes 20ms (standby (<20ms)). Most electronics handle this fine, but sensitive server equipment may hiccup. This matters if you're using it as a home UPS for always-on equipment.
Your Life, Your Pick
We ran the math on six real-world scenarios. Here's which unit survives your actual life.
Weekend Camping
2 nights
Two nights off-grid with essential comfort
The AC240P runs out of juice. It only has 1,567Wh usable, but this scenario needs 2,100Wh. The DELTA Pro covers it and still has 64h of phone charging left over.
8-Hour Blackout
8 hours
Keep the essentials running through a night without power
The AC240P runs out of juice. It only has 1,567Wh usable, but this scenario needs 1,645Wh. The DELTA Pro covers it and still has 94h of phone charging left over.
CPAP Overnight
8 hours
Sleep therapy without interruption — the #1 medical use case
Both are massively overpowered for CPAP. You're using 20% or less. Save $540 and buy the cheaper unit; the extra capacity is wasted on a 40W medical device. Instead, invest in a second battery for multi-night camping trips.
Remote Workday
8 hours
Full work day off-grid without power anxiety
The DELTA Pro gives you a comfortable buffer at 30%. Enough to work late, join extra video calls, or charge a second device without worry. The AC240P at 58% works but leaves less room for the unexpected. For daily remote work, that peace of mind matters.
Tailgate Party
4 hours
Game day power for the crew
Both handle it, but neither is stressed. Tailgating is a light load. The DELTA Pro's extra margin is nice but not decisive here. Consider weight instead: you're carrying this to a parking lot, and 27 lbs makes a real difference when loading up.
Van Life Daily
24 hours
A full day of mobile living — the ultimate endurance test
Neither unit can fully handle this scenario (needs 4,685Wh). You'd need a higher-capacity station or to cut back on usage.

Growth Path
DELTA Pro
✓ ExpandableSupports expansion batteries from EcoFlow. You can increase capacity without replacing the base unit. A significant long-term advantage.
Accepts up to 1,600W of solar. Enough for a serious multi-panel array.
Generous port selection supports complex multi-device setups.
Expansion batteries are EcoFlow-specific. You're investing in the EcoFlow ecosystem.
AC240P
✓ ExpandableSupports expansion batteries from BLUETTI. You can increase capacity without replacing the base unit. A significant long-term advantage.
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.
Both units support expansion, but the DELTA Pro's higher solar ceiling (1,600W vs 1,200W) gives it a stronger off-grid growth path. More solar input means you can add panels as your setup grows.
The Bottom Line
The full picture comes down to this. The DELTA Pro 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 DELTA Pro nor the AC240P feels like the right fit, your power needs probably sit outside what these two target.

Both EcoFlow and BLUETTI discount regularly, so check the current price before committing. Prime Day and Black Friday pricing typically drops 20-30%.
Frequently Asked Questions
DELTA Pro vs AC240P — answered by our testing team.
Q.Is the AC240P worth $540 more than the DELTA Pro?
A tough sell. The AC240P offers 27 lbs lighter despite higher specs — better engineering, not just bigger batteries, but $540 is a steep premium for a single upgrade. At $0.39/Wh, the DELTA Pro delivers better bang for your buck. Unless that advantage is non-negotiable, save the cash. Better yet, put it toward a solar panel that pays for itself in free charges.
Q.How does the 1,757Wh capacity difference actually affect daily use?
The DELTA Pro's 3,600Wh battery keeps a mini-fridge running for roughly 20 hours vs the AC240P's 10 hours. Where it really matters: during an 8-hour blackout running your fridge, router, lights, AND charging your phone simultaneously (about 1,645Wh total), the DELTA Pro handles it while the AC240P runs dry. What specs don't mention: runtime drops 20-30% in cold weather (below 32°F/0°C) as battery chemistry slows down. The DELTA Pro'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.
Q.Can I actually carry the DELTA Pro, or is the AC240P the only portable option?
Neither is "portable" in any hiking sense. The AC240P (72 lbs) and the DELTA Pro (99 lbs) are both appliances you place and leave. The 27-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.
Q.How fast can each unit recharge from solar panels in real conditions?
On paper, the DELTA Pro accepts 1,600W vs the AC240P's 1,200W 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 3.2 hours for the DELTA Pro and 2.2 hours for the AC240P. That gap widens on cloudy days, when the DELTA Pro'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 DELTA Pro's advantage is substantial.
Q.Is EcoFlow or BLUETTI more reliable for long-term ownership?
Both brands have strengths and trade-offs. EcoFlow: Mixed. 2-5 years depending on model (DELTA Pro Ultra line gets 10 years). Some users report smooth claims; others report runarounds. Register your product to extend coverage. BLUETTI: Check manufacturer warranty policy directly One piece of advice from the power station community: regardless of brand, buy from Costco or Amazon. Their return policies provide a safety net that manufacturer warranties alone can't match, especially for a product you'll rely on in emergencies. Both brands use LFP (lithium iron phosphate) batteries in their current lineup, the most proven chemistry for longevity and safety.
Q.Bottom line: should I buy the DELTA Pro or the AC240P?
We'd buy the DELTA Pro. Cheaper and more capable. That combination is rare. The AC240P doesn't offer a compelling reason to spend more unless you specifically need a feature unique to the BLUETTI ecosystem (expansion batteries, app integrations). Otherwise, clear call.
