BLUETTI AC240P vs DJI Power 500
The BLUETTI AC240P (1,843Wh) and DJI Power 500 (512Wh) 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? 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 can run a window AC unit, a full-size fridge, or power tools. The Power 500's 1,000W inverter will flat-out refuse to start those appliances. On stamina, the AC240P keeps a fridge alive for roughly 10 hours vs the Power 500's 3 hours. The cost? Portability. At 72 lbs, the AC240P is heavy enough to make you think twice about moving it. The Power 500 at 16.1 lbs is something one person can actually carry.
Pick the AC240P if your primary use is cpap overnight or remote workday. Go with the Power 500 if you need the heavier-duty specs for demanding loads. Most buyers overlook this: the Power 500 costs ~$0.18/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.

Power 500 Analysis
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 16.1 lbs, it is exceptionally portable. You can easily carry it one-handed to a campsite or tailgating party.
Strengths
- Save $1,580 vs Competitor
- 55.9 lbs Lighter
Trade-offs & Considerations
- Weaker inverter (-1,400W) limits appliance compatibility.
- Battery capacity cannot be expanded if your needs grow.
What the Specs Don't Tell You
Hidden gotchas and advantages we spotted that you won't find on the product page.
AC240P: 72 lbs Is a Commitment
NoteAt 72 lbs, this is manageable but not fun to carry. That's heavier than a large checked suitcase. Moving it from your car to a campsite requires some effort and flat terrain.
AC240P: 45dB Under Load
Note45dB 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.
Power 500: No Expansion Path
Watch outThe Power 500 is a closed system. The 512Wh you buy today is the ceiling. If your power needs grow (more gear, longer trips, partial home backup), you'd need to buy a completely new unit. The AC240P can add expansion batteries.
Surge Power: Inverter Quality Indicator
AdvantageThe AC240P has a 1.5× surge-to-continuous ratio vs the Power 500's 1×. 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 Power 500 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 Power 500 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.
Warranty Value Comparison
NoteThe Power 500 gives you 13.9 years of warranty per $1,000 spent, vs the AC240P's 3.1 years. That's 4.5× more coverage per dollar. An underrated factor if you're keeping this unit for years.
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
Neither unit can fully handle this scenario (needs 2,100Wh). You'd need a higher-capacity station or to cut back on usage.
8-Hour Blackout
8 hours
Keep the essentials running through a night without power
Neither unit can fully handle this scenario (needs 1,645Wh). You'd need a higher-capacity station or to cut back on usage.
CPAP Overnight
8 hours
Sleep therapy without interruption — the #1 medical use case
Both are massively overpowered for CPAP. You're using 74% or less. Save $1,580 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 Power 500 runs out of juice. It only has 435Wh usable, but this scenario needs 910Wh. The AC240P covers it and still has 44h of phone charging left over.
Tailgate Party
4 hours
Game day power for the crew
The Power 500 runs out of juice. It only has 435Wh usable, but this scenario needs 670Wh. The AC240P covers it and still has 60h of phone charging left over.
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.

Very new to the power station space — only ~2 years of track record. No built-in solar charge controller (requires separate proprietary adapter). SDC ports are proprietary to DJI ecosystem. Limited "plug-and-play" value for non-DJI users. No expansion battery ecosystem yet.
BLUETTI and DJI are close competitors. Both have established support channels and growing ecosystems. Compare their specific warranty terms and community size for your peace of mind.
Growth Path
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.
Power 500
🔒 Closed SystemClosed system. What you buy is what you get. If your needs outgrow 512Wh, you'll need to purchase an entirely new unit.
Accepts up to 300W of solar. Limited to a single portable panel.
Adequate ports for most setups, but heavy users may want a power strip.
If your power needs might grow (more camping gear, longer trips, partial home backup), the AC240P's expansion path saves you from buying a whole new unit in 2 years. That flexibility has real dollar value.
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 Power 500 wins in the scenarios that match your life, it's the right choice regardless of aggregate scores.
If neither the AC240P nor the Power 500 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 and DJI discount regularly, so check the current price before committing. Prime Day and Black Friday pricing typically drops 20-30%.
Frequently Asked Questions
AC240P vs Power 500 — answered by our testing team.
Q.Is the AC240P worth $1,580 more than the Power 500?
The short answer: yes, if you'll actually use the extra capability. The AC240P costs $1,580 more, but that premium buys you 1,331Wh more battery capacity (that's 8 extra hours of running a mini-fridge); 1,400W higher AC output (opening the door to more demanding appliances); 900W faster solar charging for quicker off-grid recovery. On a cost-per-watt-hour basis, you're paying $1.05/Wh vs $0.70/Wh. For regular use, we'd pay the premium.
Q.How does the 1,331Wh capacity difference actually affect daily use?
The AC240P's 1,843Wh battery keeps a mini-fridge running for roughly 10 hours vs the Power 500's 3 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.
Q.Can I actually carry the AC240P, or is the Power 500 the only portable option?
At 16.1 lbs, the Power 500 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 Power 500 wins decisively.
Q.How fast can each unit recharge from solar panels in real conditions?
On paper, the AC240P accepts 1,200W vs the Power 500's 300W 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 2.4 hours for the Power 500. 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.
Q.What happens if I outgrow the Power 500's 512Wh capacity?
With the Power 500, you'd need to buy an entirely new power station. It's a closed system with no expansion port. The AC240P supports BLUETTI-compatible expansion batteries that can double or triple your total capacity without replacing the base unit. Say you start with weekend camping and six months later you want to run a mini-fridge full-time in a van. The AC240P scales with you. The Power 500 forces a repurchase. Worth considering even if you don't need more capacity today. Power needs tend to grow.
Q.Is BLUETTI or DJI more reliable for long-term ownership?
Both brands have strengths and trade-offs. BLUETTI: Check manufacturer warranty policy directly DJI: 3-5 years depending on model. DJI has a reasonable track record from drone products. Too early for comprehensive power station warranty data. 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 AC240P or the Power 500?
We'd pay the premium for the AC240P. Yes, it costs more. The capability jump is real: you're stepping into a tier that handles appliances the base model can't start. The Power 500 is still solid if budget is the priority, but the AC240P will leave you less likely to wish you'd "gone bigger" six months from now. That regret costs more than the price difference.
