Head-to-head test
BLUETTI Elite 400 vs DJI Power 500
Add up one day's watt-hours before you look at either price tag: under 435Wh and the Elite 400 is 69 extra pounds and $1,100 of battery you'll never discharge; over it, the Power 500 doesn't finish the day.

Spec deltas
The Elite 400 stores 3,840Wh and the Power 500 stores 512Wh, which is seven and a half times the battery for under four times the money. Across the six loads modelled on this page, the DJI runs out on five of them and the Elite runs out on one. That looks like a rout, and on the numbers it is.
The rout only matters if you were ever going to fill the bigger battery. The Power 500 weighs 16.1 lbs and costs $299. It's the box you carry in one hand to a nightstand or a picnic table, and for a CPAP, a laptop and a camera kit it's simply the correct size. The Elite is 85 lbs. You move it once and then it lives there.
The real work here is arithmetic you can do before you finish this paragraph. Add up one day of actual load. If the answer is a few hundred watt-hours, buy the DJI and skip the rest of this page. If it involves a fridge, a power tool, or a night the grid is down, the Elite 400 is the only one of the two that finishes, and per unit of energy it's also the cheaper one, which is the part nobody expects.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
There's no load on this page where the Power 500 is the stretch pick and still gets there. Either the job fits inside 435Wh, in which case the DJI is the right box and the Elite is overkill, or it doesn't, in which case the DJI isn't a cheaper way to do that job. It's a different, smaller job wearing the same category name.
Power 500 usable capacity: 435Wh, after the 85% inverter derate on its 512Wh nameplateThe loads modelled here run from a 320Wh CPAP night to a 4,685Wh van-life dayThe Elite 400 covers the 2,100Wh camping weekend using 64% of its 3,264Wh usable
Why it mattersIf you're hoping the $299 unit will probably be enough, it won't be. Price the job, not the box.
That's fine for a camping trip you drive home from. It's the wrong shape for a blackout, which is the one situation where the wall socket is the thing that failed. The Elite 400 takes up to 1,000W of solar straight in, enough to put 3,840Wh back in about four hours at its full rated input. No real array delivers its rating all day, so read four hours as the best case rather than a promise.
Power 500 accepts 300W of solar inputDJI's power stations have no built-in solar charge controller and need a separate proprietary adapterOne review noted the Power 500 ships with only a wall plug, no solar adapters and no car-charging cablesB4
Why it mattersAnyone buying for outages or dry camping should add the price of DJI's solar adapter to the $299 before comparing anything at all.
continuous output
Motors don't ask politely. A compressor or a pump can pull two to three times its running wattage in the instant it starts, and the gap between 1,000W and 3,900W is the gap between planning for that and hoping. One bench run briefly saw 1,500WB3, which tells you headroom exists. It doesn't tell you how much, or for how long, or whether the unit will do it twice.
Elite 400: 2,600W continuous, 3,900W surge, a 1.5x cushionPower 500: 1,000W continuous and 1,000W surge, the same number printed twiceIn testing the Power 500 ran a 905W load and briefly handled 1,500W, above its own 1,000W ratingB3
Why it mattersIf anything you own has a compressor or a motor in it, treat 1,000W as the Power 500's hard planning number and buy the Elite rather than gambling on a figure nobody published.
rated cycles
Run the pessimistic end and the DJI's running cost moves against it. Three thousand cycles of a 512Wh battery is 1,536 kWh over its life, and $299 spread across that is about $0.25 per kilowatt-hour, up from the figure the table shows. The Elite's number doesn't move, because its 3,000 has no range attached to it.
Power 500 rated 4,000 cycles; Elite 400 rated 3,000DJI's own published figure is a 3,000 to 4,000 cycle range for roughly a ten-year lifeB1, while the spec sheet carries the flat 4,000Power 500 price $299; Elite 400 price $1,399
Why it mattersDon't let the cycle count tip you toward the DJI. It's the row most likely to be flattering itself, and even at its most flattering it still loses on cost per kilowatt-hour.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: The Power 500 finishes one of the six loads modelled here, and which one it is tells you whether you need the Elite at all.
One of these two finishes the CPAP night and nothing else on the list. The Power 500 clears that 320Wh load with 115Wh to spare and comes up short on every other profile here, by 235Wh at a tailgate and by 1,665Wh on a camping weekend. The spread across those two misses is the useful part: at a tailgate it's a near thing, at a campsite it was never close.
The Elite doesn't walk this table clean either. It's the only unit here that covers a camping weekend and an eight-hour outage without you thinking about it, and reviewers still call it compromised: two AC sockets on a 2,600W inverterA4, so the moment you want three things running at once you're adding a power strip to the cart. And on the van-life profile it runs out too.
Portability & Form Factor
Selected because: 85 lbs against 16.1 is the only axis where the smaller unit wins outright, and for a lot of buyers it settles the page on its own.
weight
Sixteen pounds is a one-handed lift out of a trunk and onto a nightstand. Eighty-five is a two-hands, bent-knees, put-it-down-where-it-lives lift, which is why BLUETTI fitted wheels and a trolley handleA2A3. The weight gap is the Power 500's entire argument, and it's a genuine one.
A trolley solves flat ground and does nothing at all for basement stairs, a tailgate lip, or a hundred yards of soft campsite. So the question isn't how heavy the Elite is, it's how often it moves. Living in one spot, a closet, a garage shelf, the corner of an RV, 85 lbs is a one-time problem and then it's furniture. Moving every weekend, it's a weekend problem every weekend.
Lifetime Value
Selected because: The $1,399 unit is the cheaper one per watt-hour stored and per kilowatt-hour over its rated life, which is the opposite of how the two price tags read.
cost / lifetime kWh
Twelve cents a kilowatt-hour against nineteen. The box that costs four figures is the cheaper one to run, because 3,000 cycles of a large battery banks far more energy than 4,000 cycles of a small one, and cost per unit of energy is the only fair way to compare two batteries this far apart in size.
That figure only counts if you spend the energy. Cost per kilowatt-hour assumes you cycle the battery; buy 3,840Wh for a job that draws a few hundred watt-hours a day and you've bought a very economical kilowatt-hour that you'll never actually use. The number is real. Whether it applies to you is what the rest of this page is about.
What the Specs Don't Tell You
Selected because: Two rows on the spec table, surge and cycle count, point the wrong way if you read them straight.
rated cycles
Two of these cards are corrections rather than warnings. The surge row and the cycle row both flatter the Power 500 when read at face value, and one of them manages it by printing a number DJI never published in the first place.
The UPS row is the straight one. Fifteen milliseconds against twenty, both in the same standby bracket, and neither is an online UPS that hands over without a break. If you're protecting a desktop and a router, either is fine. If it's something that genuinely cannot see a gap, neither of these is the product category you want.

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
Elite 400
A weekend at 2,100Wh is where the size gap stops being abstract. The Elite 400 covers it and comes home with 1,164Wh still in the tank, which is more than half the weekend over again. The Power 500 covers about a fifth of it, and no amount of careful use closes a 1,665Wh gap. If your camping involves a fridge and two nights, this one scenario is the whole decision.
Battery budget usedlower = more headroom
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
Elite 400
Eight hours of blackout load costs 1,645Wh here, and the Power 500 gets you a bit past hour two. The Elite finishes the outage with 1,619Wh left, which is very nearly the entire outage again, so the second night of a two-night storm is covered as well. That's the difference between watching the percentage and not thinking about it.
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
Power 500
The Power 500 takes this one, and not on capacity: 40W for eight hours is 320Wh, which both units clear without noticing. The tiebreak is where the box can physically sit. A 16.1 lb unit goes on the nightstand at arm's reach; an 85 lb one goes on the floor in another room, if it goes in the bedroom at all. The honest catch is margin. The Power 500 ends the night with 115Wh spare, so it's a one-night unit, and a second night without a recharge isn't on.
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
Elite 400
A 910Wh workday puts the Power 500 out somewhere around lunch. It holds roughly half of what the day costs and finishes 475Wh short. The Elite spends 28% of its usable capacity on the same day, which works out to about three and a half days of the same work before it needs a socket. If you work from a van or a cabin, that's the difference between a daily charging chore and a weekly one.

SCN-05 · 4 hours · needs 670Wh
Tailgate Party
Game day power for the crew
Elite 400
This is the closest the Power 500 comes, and it still doesn't get there: 670Wh of tailgate leaves it 235Wh short, dying about two-thirds of the way through the afternoon. That's the frustrating kind of miss, close enough to feel solvable and not actually solvable. The Elite runs the same party on 21% of its capacity and you never look at the screen.

Van Life Daily
A full day of mobile living — the ultimate endurance test
Neither unit
Neither of these is the answer here, and it's worth saying plainly rather than picking a winner. A full-time van day at 4,685Wh leaves the Elite 400 short by 1,421Wh and the Power 500 short by 4,250Wh: the Elite gets just under 70% of the way, the DJI about a tenth. If this is your real load, stop comparing these two and look at the next capacity class up, or at a hard-wired 12V house system.

Conclusion
August 9, 2026
Verdict: the Elite 400, on Power Score margin
Take the Elite 400 if both of these are genuinely on the same shortlist, because a shortlist containing both means the job hasn't been sized yet, and every sizing exercise on this page lands the same way: the Power 500 finishes one of the six modelled loads and the Elite finishes five. The surprise is that the expensive box is also the cheap one, at $0.36 per watt-hour of capacity against $0.74. Confidence sits at six rather than nine for a single reason, and it's a reason you can settle yourself in ten seconds: if your honest daily draw is under the Power 500's usable ceiling, the Elite is weight and money you'll never touch, and the DJI becomes the correct purchase instead. Answer that question and this page answers itself.
Today the Elite 400 is $1,299, $100 under its typical $1,399. The verdict weighs typical prices, not today's. Prices checked 1 day ago.

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, Elite 400 rates 3.8/5 (27th percentile of 16 Home Backup-class units), and Power 500 rates 4.6/5 (74th percentile of 20 Compact-class units).

Hidden gotchas and advantages we spotted that you won't find on the product page.
Elite 400: 85 lbs Is a Commitment
At 85 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.
Surge: One of These Numbers Was Never Published
The Elite 400 is rated 2,600W continuous with a 3,900W ceiling, a 1.5x cushion for the moment a motor starts. The Power 500's surge figure is 1,000W, which is exactly its continuous rating. Read that as a spec DJI didn't publish rather than a promise the inverter has no headroom at all, because every inverter has some. What it means for you is the same either way: 1,000W is the number you can plan against, and compressors and pumps can pull two to three times their running wattage in the instant they start. The Elite has documented room for that. The Power 500 has room nobody has quantified.
UPS: 15ms vs 20ms, Same Bracket
The Elite 400 switches to battery in 15ms and the Power 500 in 20ms. Both are standby-class, which means both let the load see a brief break, and neither is an online UPS that carries through without one. A desktop, a router or a NAS rides that out. Anything that genuinely cannot tolerate a gap needs a different product category, not a different one of these two. Five milliseconds is not a reason to choose either.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here. Both figures are maximums rather than guarantees: BLUETTI's depends on buying direct from BLUETTI or registering the unit, since reseller purchases carry a shorter term; DJI's on buying from DJI's own store, which is where the full five years is advertised. Worth saying because the per-dollar framing can suggest otherwise: the Power 500 works out at 16.7 years of cover per $1,000 spent against the Elite 400's 3.6, but that spread is the price gap, not the terms.
Cycles Aren't Kilowatt-Hours
The Power 500 is rated for 4,000 cycles against the Elite 400's 3,000, and on that row it wins. Cycles aren't energy, though. Three thousand turns of a 3,840Wh battery banks 11,520 kWh over the rated life, while 4,000 turns of a 512Wh one banks 2,048. That's five and a half times the total energy from the unit with the lower cycle count. And when either one reaches its limit the battery doesn't die; it settles at around 80% of original capacity and carries on.
Full record above — the Test Desk pick is the Elite 400.

Analyst note
The Power 500 is cheaper to buy, but the Elite 400 is cheaper to own. At $0.12/kWh over its lifetime vs $0.15/kWh, the Elite 400's higher cycle life and capacity make each dollar go further over the years. One caution on the lifespan row: the Power 500 takes longer to reach its cycle rating, but a cycle moves a different amount of energy on each unit — the Elite 400 still delivers more over its shorter horizon (11,520 vs 2,048 kWh). Years measure wear, not usefulness.
Brand trust
BLUETTI
Ecosystem
One of the broadest lineups — 15-20+ models from budget (AC2A) to flagship portable (Apex 300, 2764.8Wh). Includes specialized products: vehicle solar hubs, sodium-ion cold-weather units, and balcony storage systems.
Support
The weak spot, and worth pricing in at this cost. Support is email-led with China-timezone delays, and outcomes are inconsistent: quick resolutions in some cases, weeks of back-and-forth in others, repairs sometimes swapped for a discount on a new unit, and awkward claims when the unit came from a third-party seller. Buying direct from BLUETTI is the single thing that most improves the odds.
Community
Active and growing — Reddit r/bluetti has a dedicated community. Second-largest after EcoFlow in engagement.
App experience
Rated 4.5/5 iOS and Android — tied for best app experience in the category. V3.0 UI redesign was well-received.
Unique strength
Some of the best capacity-per-dollar in the category, and the widest catalogue in it: 15 to 20 models running from budget units up to flagship portables, plus genuinely unusual hardware like sodium-ion cold-weather stations and combined solar-and-alternator vehicle hubs. Every current unit is LFP. Cycle ratings vary by model, though, so read the one you're buying rather than the lineup average. The Elite 400 is rated at 3,000.
Worth knowing
Customer support inconsistency is the #1 risk factor. Older/discontinued units may become unrepairable — no spare parts policy for some models. Some reports of erratic communication from support agents.
DJI
Ecosystem
New entrant (2024) — five power station models to date: Power 500, Power 1000 (since superseded by the V2 but still sold), Power 1000 V2, Power 1000 Mini, Power 2000. Buying a "Power 1000" listing? Check which revision it actually ships.
Support
Leveraging DJI's established global support and repair center network from the drone business. Generally positive reputation inherited from drone operations, but limited power-station-specific track record.
Community
No dedicated power station community yet. Discussions happen within r/dji (~250K members, mostly drone users). Very small power-specific presence on Facebook and forums.
App experience
Rated 3.5/5 iOS and Android (DJI Home app ratings reflect entire DJI ecosystem including drones/cameras, not power-station-specific). Users report the on-device screen is more reliable than the app.
Unique strength
Runs quiet — 23-30dB published on most of the range (manufacturer best-case figures), at the quiet end of the category; our record carries no figure for the Power 1000 V2. Fast wall charging, quickest on the Power 1000 V2 at ~56 min — that figure is the V2's, not the whole line's. 700+ battery patents from drone R&D. SDC ports for ultra-fast DJI drone charging. Premium industrial design and build quality. LFP batteries rated for 4,000+ cycles.
Worth knowing
A recent entrant to power stations, arriving long after the established players, so there is less long-term field data than for EcoFlow, Jackery or BLUETTI — though DJI brings a deep hardware track record from drones. No built-in solar charge controller (requires a separate proprietary adapter). SDC ports are proprietary to the DJI ecosystem, so their fast-charging advantage mostly benefits people who already own DJI gear. Battery expansion is available on the newer Power 2000 and Power 1000 V2, but not on the earlier Power 1000 or Power 500 — check the specific model.
Analyst note
Two very different bets. BLUETTI has been doing this for years and has the catalogue and the community to show for it, with support as the known weak point. DJI arrived in 2024 with four models, a drone company's manufacturing behind it and a global service network already built, but very little power-station-specific track record and no real owner community yet. On a $299 unit that asymmetry barely registers. On something you expect to keep for years, it's the part of the decision the spec table can't show you.
Growth path
Elite 400
FIXED CAPACITYFixed at 3,840Wh — a sealed, complete system rather than a starting point. There's no expansion port, so that figure is the ceiling: check it against your longest unplugged stretch before you buy.
Accepts up to 1,000W of solar. Enough for a serious multi-panel array.
Adequate ports for most setups, but heavy users may want a power strip.
Power 500
FIXED CAPACITYFixed at 512Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.
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.
Realistic full solar rechargeat 70% of rated panel output — see methodology
Analyst note
Neither expands, and that's no knock on either — each is a complete unit at a fixed size. Buy the capacity that covers your needs now (the Elite 400 gives you the larger ceiling); you can't add to either later.
What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
BLUETTI Elite 400
Reviewers put the Elite 400 among the more complete units at the 3,000Wh-plus tier: 3,840Wh of LFP, 3,900W of Power Lifting surge, a 70-minute fast charge and 15ms UPS, with a built-in trolley so the mass has somewhere to goA1A2. The weight itself draws mixed notes, called hefty but lighter than some rivals at this capacity, with the wheels doing real workA3.
The consistent complaint is what BLUETTI left out. Two AC sockets and no battery expansion get flagged as the compromises that stop it being the obvious pick, good but not quite as good as it could have beenA4, and that pairing recurs across reviews rather than sitting in one outlierA2A4. Worth saying plainly: what's on record for both units here is review-desk testing, not owners two years inA1A3.
“BLUETTI's largest Elite-range unit — a 3,840Wh LiFePO4 battery with 2,600W continuous output (3,900W Power Lifting), fixed at native capacity with no expansion.”

DJI Power 500
The Power 500's field record is short but consistent: a 512Wh LFP pack good for up to 1,000W, automotive-grade cells DJI puts at 3,000 to 4,000 cycles and roughly a ten-year life, and about 7.3 kg to carryB1B2. One test ran it at 905W and watched it briefly hold 1,500W above its own rating, and found it more efficient than the larger DJI Power 1000B3.
The recurring gripe is the box it arrives in. One review noted it ships with a wall plug and nothing else, no solar adapter and no car-charging cableB4. For a unit whose whole appeal is going places, that's a second purchase before it does the thing you bought it for.
“A 512Wh LFP battery with up to 1,000W output; the automotive-grade LFP cells are rated up to 3,000-4,000 cycles for roughly a 10-year lifespan.”

“Powerful, but reviewers flag only two AC sockets and no battery expansion as compromises — good but not quite as good as it could have been.”

Who Should Buy Which
Buy the Elite 400 if you…
- →You want an eight-hour outage to be a non-event, with enough left in the tank that a second night doesn't change your plans.
- →You car-camp or run a two-night basecamp with a fridge going, and you'd rather load one heavy box than juggle two small ones.
- →Something you plug in has a motor: a fridge, a pump, a corded tool. The 3,900W ceiling is the whole reason to be here.
- →The unit is going to live in one place, a garage shelf or the corner of an RV, where 85 lbs is a one-time problem.
Buy the Power 500 if you…
- →Your load is a CPAP, a laptop, a phone and a camera kit, and the box needs to sit within arm's reach on a nightstand.
- →You already fly DJI. The SDC ports fast-charge DJI drone batteries, which is a reason that exists for you and for nobody else.
- →It rides in a trunk and gets carried the last stretch by one person with one hand.
- →You'll recharge from a wall socket, at home or at a campground, and you have no plans to build a solar setup.
If neither fits
Two groups should close this tab. Full-time van dwellers, and anyone running a genuine off-grid day of the kind modelled at the bottom of this page, will find both units come up short, so shop the next capacity class up or a hard-wired 12V house system rather than choosing between these. And anyone whose honest daily draw lands in the gap between them, which the 670Wh tailgate and the 910Wh workday here describe exactly, is being asked to pick between too little battery and far more box than the job needs. A mid-size station, bigger than the Power 500 and a fraction of the Elite's 85 lbs, is the right answer, and neither of these is it.
The Bottom Line
Buy the Elite 400 if your day doesn't fit inside the Power 500, which on this page's evidence means almost any day with a fridge, an outage or a second night in it. It finishes five of the six modelled loads and the DJI finishes one, and the part that surprises people is that the bigger box is also the cheaper energy: not just cheaper per watt-hour of capacity, but cheaper per kilowatt-hour across the whole rated life.
The honest version of that verdict is a question rather than a command. If you can name the watt-hours you'll actually use and the number is small, the Power 500 is the right box and the Elite is 85 lbs of unspent capacity sitting in your garage. If you can't name the number, that's an answer too. The unit you'll regret is the one that runs out, and it isn't the big one.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the BLUETTI Elite 400 worth almost four times the price of the DJI Power 500?
Per unit of energy it's actually the cheaper of the two: it stores seven and a half times as much for under four times the money, and it costs less per kilowatt-hour across its rated life. Whether that's worth it to you comes down to one thing, which is how many watt-hours you genuinely use in a day. Below the Power 500's usable ceiling, the Elite is capacity you pay for and never discharge.
Can the DJI Power 500 run a refrigerator?
Plan against 1,000W and you're fine on paper, but the surge question is unresolved: DJI lists the same 1,000W for surge as for continuous output, which means the headroom isn't published rather than that it's absent. A compressor can draw two to three times its running wattage at startup, and that's exactly where a small inverter trips. One test did briefly see 1,500W. Capacity is the bigger obstacle anyway, since on the eight-hour blackout profile here the Power 500 covers roughly a quarter of the load.
Which one should I get for a CPAP?
The Power 500, and the reason is furniture rather than electronics. A CPAP is roughly 40W for eight hours, so both units clear the night several times over on capacity. What differs is that a 16.1 lb box sits on a nightstand and an 85 lb one does not. Just know the DJI finishes that night with 115Wh spare, so a second night without recharging isn't happening.
Can you add more batteries to either of these?
No. Both are fixed, at 3,840Wh for the Elite 400 and 512Wh for the Power 500, with no expansion port on either one. That isn't a flaw in either case, since both are complete units rather than starter kits, but it does mean you buy the size you need on day one. DJI's newer Power 2000 and Power 1000 V2 do take expansion batteries; the Power 500 doesn't.
Can I recharge either one from solar during a blackout?
The Elite 400 takes up to 1,000W of solar straight in with nothing extra to buy. The Power 500 accepts 300W, but DJI's stations have no built-in solar charge controller and need a separate proprietary adapter, and one review noted the unit ships with only a wall plug. Budget for that adapter before you compare the two prices, because a blackout is precisely the moment the wall socket stops being an option.
