BLUETTI AC50B vs DJI Power 500
The DJI Power 500 is the cheaper box and the bigger one on capacity, inverter and cycle life at once, which leaves the AC50B arguing from a 12V car socket and 1.3 lb.

Spec deltas
The DJI Power 500 is the cheaper of these two, and it isn't the smaller one by any measure. At $299 against the AC50B's $399, it holds 512Wh to 448, runs a 1,000W inverter to 700, and is rated for 4,000 cycles to 3,000. You usually pay extra for that list. Here you keep $100.
So the AC50B needs a specific reason, and it has exactly one worth naming: a 12V car socket, which the Power 500 doesn't have. If a 12V cooler or a tire inflator plugs straight into the station, that's real. The 1.3 lb weight advantage is not. Pound for pound the two carry nearly the same energy, and the DJI's extra heft is its extra 64Wh.
The DJI's catch is solar. DJI builds no solar charge controller into the unit, so its 300W solar input needs a proprietary adapter bought separately, and the box ships with a wall plug and nothing elseB4. Price that in if panels are the plan. If you charge from the wall, it costs you nothing.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
The Power 500 doesn't need the trick. Its inverter is rated for the full 1,000W, so the same kettle gets everything it asks for, and reviewers saw it hold a 905W load in testingB3. The AC50B's signature feature is a workaround for a limit the cheaper unit doesn't have.
AC50B: 700W continuous output; surge figure unpublishedAC50B Power Lifting: runs resistive appliances rated up to 1,000W by delivering less power than they ask forPower 500: 1,000W continuous outputin testing the Power 500 ran a 905W loadB3
Why it mattersIf a kettle or a small heater is why you're shopping, the DJI runs it at full speed and the AC50B runs it at a discount.
rated cycles
That works out to $0.15 per lifetime kilowatt-hour for the DJI against $0.30 for the AC50B. The BLUETTI charges twice as much for every unit of energy it will ever deliver, and that's before counting its smaller inverter.
AC50B: 3,000 rated cycles x 448Wh = 1,344 lifetime kWhPower 500: 4,000 rated cycles x 512Wh = 2,048 lifetime kWhtypical prices: AC50B $399, Power 500 $299
Why it mattersAnyone who'll cycle this battery every week for years should stop comparing stickers; the DJI wins the receipt and the long run both.
That 12V socket is the AC50B's one structural edge. A 12V compressor cooler or tire inflator plugs straight in. On the DJI, a 12V-only device needs an AC adapter of its own or it doesn't run at all.
AC50B: 1 AC outlet, 1 12V car socket, USB-C up to 65WPower 500: 2 AC outlets, no 12V car socket, USB-C up to 100W
Why it mattersCar campers running a 12V fridge have a genuine reason to pay more for the AC50B; everyone else gets more sockets from the DJI.
That cushion is the difference that holds up, because the noise ratings don't: each maker measures its own way, so 25 against 45 can't promise a quieter bedroom. The margin can. At 40W, 61Wh is about 1.5 hours of slack and 115Wh is about 3 (each divided by 40W), which is what covers a night that runs long.
CPAP Overnight: about 40W for eight hours, 320WhAC50B: 381Wh usable after the flat 85% derate, 61Wh left by morningPower 500: 435Wh usable after the same derate, 115Wh left by morningnoise: 45dB is BLUETTI's rating, 25dB is DJI's best-case rating; the makers measure differently
Why it mattersA CPAP user choosing between these two should take the DJI for the margin, then look for hands-on noise reports before either one goes beside the pillow.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: The DJI costs less to buy and half as much per lifetime kilowatt-hour, which is where this verdict is settled.
cost / lifetime kWh
Cheaper sticker, half the cost per kilowatt-hour. That combination leaves the AC50B no column to win here. Its pack is rated for 1,344 lifetime kWh against the DJI's 2,048, so at a cycle a day it reaches its rated count in about 8.2 years against 11.
Both cycle counts are minimums, so neither battery falls off a cliff at the number. But there's nothing to amortize in this pair. Normally the pricier unit earns its premium back over years of use; here the pricier unit is also the shorter-lived one.
What the Specs Don't Tell You
Selected because: Power Lifting is the AC50B's headline feature and the DJI's 1,000W inverter makes it moot; the noise card needs careful reading too.
rated cycles
Power Lifting is the AC50B's signature card, and the DJI turns it into trivia. A 1,000W resistive load that the BLUETTI runs underfed, the DJI's rated inverter runs at full power. The mode also does nothing for a compressor, a pump or a power tool, and BLUETTI publishes no surge figure for this unit, so don't read Power Lifting as starting ability.
The noise card comes with a footnote. The 45 and 25 decibel figures are each maker's own rating, DJI's are best-case numbers, and nobody measured the two the same way, so don't treat the spread as something you'll hear. Warranty is a genuine tie at up to five years each, and the cycle card is one more line in the DJI's favor.
Your Life, Your Pick
Selected because: Five of six rows are too big for either unit; the CPAP row is the one with a winner, and it's decided on leftover margin.
Five of six rows end the same way: neither. A 448Wh or 512Wh battery isn't a camping-weekend, blackout or van-life battery, and both come up more than 1,000Wh short on all three. The DJI covers a bigger slice of every row, which is what 64 extra watt-hours buys, but no row flips.
CPAP is the row with a winner, and the DJI takes it on what's left in the tank at dawn, nearly double the AC50B's. That's a quieter kind of win than a noise rating, and a more trustworthy one.
Brand Trust
Selected because: The DJI's missing solar controller and BLUETTI's uneven support are the two brand facts a buyer of either should weigh.
BLUETTI's reputation is capacity per dollar, built on its Elite and Apex units. This is the matchup where that reputation goes missing: against this DJI, the AC50B is the pricier box per watt-hour. What BLUETTI does bring is a deeper catalogue and an app rated 4.5/5, against DJI's 3.5/5 score that also covers its drones and cameras.
DJI arrived in 2024 with its drone business's repair network behind it, which is a better support starting point than BLUETTI's email-first, timezone-delayed queue. The DJI's real brand cost is hardware: no built-in solar charge controller, so solar is a separate purchase, and no expansion on the Power 500. Neither expands, so size for the battery you need today.

Both carry a 40W machine through eight hours, and the DJI takes the row on margin: 115Wh left by morning against the AC50B's 61. At 40W that's about 3 hours of slack against 1.5, which is what covers a night that runs long. The two noise ratings come from different makers measuring different ways, so check hands-on reports before either goes beside the bed.

Conclusion
October 11, 2026
Verdict: the Power 500
Buy the DJI Power 500. At $299 against $399 it's the cheaper unit, and it still holds 64Wh more, runs a 1,000W inverter to the AC50B's 700W, takes 300W of solar to 200W, and is rated for 4,000 cycles to 3,000. Over the pack's rated life that's $0.15 per kilowatt-hour against $0.30, half the cost. The catch is solar: DJI builds no solar charge controller into its units, so that 300W input needs a proprietary adapter sold separately. The DJI also has no 12V car socket. Take the AC50B only if you need that socket for a 12V cooler or inflator straight off the station, and accept paying $100 more for less of everything else.

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, AC50B rates 4.6/5 (79th percentile of 25 Personal-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.
Two Ratings, Two Rulers
BLUETTI rates the AC50B at 45dB and DJI rates the Power 500 at 25dB, but each maker measures its own way and DJI publishes best-case figures, so the spread isn't a gap you can count on hearing. Neither number describes a light overnight load. If the unit is going beside a bed, look for hands-on reports first.
A Workaround the DJI Doesn't Need
Power Lifting lets the AC50B's 700W inverter run a resistive appliance rated up to 1,000W by giving it less power than it asks for, so a kettle boils slower and a heater heats slower. It works only on resistive loads, so it does nothing for a compressor, a pump or a power tool, and BLUETTI publishes no surge figure for this unit. The Power 500's inverter is rated for 1,000W continuous, so it runs the same kettle at full power with no special mode.
Five Years Each, Bought the Right Way
Both carry up to 5 years of cover, and both terms depend on where you buy: BLUETTI's full term applies when bought direct or registered, DJI's when bought from DJI's own store. Reseller purchases can carry less. Coverage doesn't separate these two, so buy from the maker either way.
Eleven Years Against Eight
The Power 500 is rated for 4,000 cycles to the AC50B's 3,000. At a cycle a day that's about 11 years against 8.2 before either reaches its rating, and both ratings are minimums. Past that point the pack doesn't quit; it holds roughly 80% of its original capacity and keeps working.

Brand trust
BLUETTI
Ecosystem
One of the widest lineups in the category, from budget units to flagship portables, plus sodium-ion cold-weather models and vehicle solar hubs.
Support
The most inconsistent support in the space: email-first, China-timezone delays, and outcomes that range from smooth to weeks of back-and-forth. Buying direct tends to go better.
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
Capacity per dollar is the brand's reputation, earned on its Elite and Apex units. The AC50B isn't where it shows; against this DJI it's the pricier box per watt-hour.
Worth knowing
The app rates 4.5/5 on iOS and Android, tied for the best in the category.
DJI
Ecosystem
A 2024 entrant with five power station models so far. The Power 500 doesn't expand; battery expansion exists only on the newer Power 2000 and Power 1000 V2.
Support
Runs through DJI's established drone repair network, which carries a good reputation, but the power-station-specific track record is short.
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
Quiet by maker rating, with 23-30dB published across most of the range as best-case figures, plus 700-plus battery patents from drone work.
Worth knowing
No built-in solar charge controller, so solar input needs a proprietary adapter bought separately. The app's 3.5/5 score covers DJI's drones and cameras too, and users find the on-device screen more reliable.
Analyst note
BLUETTI has the deeper catalogue and the better-rated app; DJI has the newer brand with the stronger repair network behind it. Neither profile changes this matchup. The DJI's lead is printed on the box, and the brand question only decides which support queue you'd rather be in if something breaks.
Growth path
AC50B
FIXED CAPACITYFixed at 448Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.
Accepts up to 200W of solar. Limited to a single portable panel.

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 Power 500 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 AC50B
Reviewers keep coming back to the carry: at 14.8 lbs the AC50B undercuts BLUETTI's own AC70 at 21.4 lbs, and they treat it as a genuine sub-15-lb portableA2. Charging is quick for the class, about 3 hours on standard AC or 1.25 hours with the optional 480W Turbo chargerA3.
Two things in the record need a footnote. Reviewer coverage quotes 2,500-plus cyclesA1, below the 3,000 our spec record carries, and the B80 pack that looks like expansion is scoped by BLUETTI's own FAQ to Power Bank Mode, where it recharges the AC50B rather than extending itA4. The coverage we haveA1A2A3 doesn't address fan noise, so the 45dB rating stands unconfirmed either way.

DJI Power 500
Reviewers back the output claim under load: in testing the Power 500 ran a 905W load, briefly took a 1,500W surge above its 1,000W rating, and came out more efficient than DJI's larger Power 1000B3. The cells are rated for up to 4,000 cycles, roughly a ten-year lifespanB1, and reviewers call it easy to move at about 7.3 kgB2.
The one caveat in the coverage is the box. One reviewer noted it ships with a wall plug only, no solar adapter or car-charging cableB4. That lines up with DJI's lack of a built-in solar controller, so solar buyers should expect a second purchase.

Who Should Buy Which
Buy the AC50B if you…
- →You car-camp with a 12V compressor cooler or run a tire inflator off the station and want the 12V socket on the unit itself; the DJI has none.
- →You're putting together a small solar kit, 200W of panel input is plenty, and you'd rather panels plug in without buying DJI's separate adapter.
Buy the Power 500 if you…
- →You want the most battery for the money at this size: more capacity, the bigger inverter and more rated cycles, for $100 less.
- →You're running a CPAP and want the bigger leftover margin when the alarm goes off.
- →You charge a laptop over USB-C and want the 100W port, or you need two AC plugs without hunting for a power strip.
If neither fits
If the plan is riding out an eight-hour blackout or a full camping weekend, close this tab. Those loads run 1,645Wh and 2,100Wh, and both units cover roughly a fifth to a quarter of that. Look at a station several times this size instead.
The Bottom Line
The Power 500 costs less and delivers more: more capacity, a real 1,000W inverter where the AC50B needs a workaround to get near that number, and half the cost per lifetime kilowatt-hour. Solar buyers owe DJI an adapter. Everyone else owes it nothing extra.
Buy the AC50B only if a 12V socket on the station is non-negotiable. Otherwise take the DJI and keep the $100.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the DJI Power 500 better than the BLUETTI AC50B?
Yes, for nearly every buyer. It costs $100 less at typical prices, holds 512Wh to 448, runs a 1,000W inverter to 700, and is rated for 4,000 cycles to 3,000. The AC50B's one real advantage is a 12V car socket, which the DJI lacks.
Can the BLUETTI AC50B run a 1,000W kettle?
Yes, through Power Lifting, which runs resistive appliances rated up to 1,000W by feeding them less power than they ask for, so the kettle boils more slowly. It only works on resistive loads like kettles and heaters, not compressors or pumps. The DJI Power 500's inverter is rated for 1,000W continuous, so it runs the same kettle at full power.
Does the DJI Power 500 need an adapter for solar panels?
Yes. DJI doesn't build a solar charge controller into the unit, so its 300W solar input needs a proprietary adapter sold separately, and one reviewer noted the box includes only a wall plug. The AC50B accepts up to 200W of solar.
Which is better for a CPAP, the AC50B or the Power 500?
The Power 500, on margin. Both carry a 40W machine through eight hours, but the DJI finishes with 115Wh left against the AC50B's 61Wh. On noise there's no measured answer: DJI rates the Power 500 at 25dB and BLUETTI rates the AC50B at 45dB, but each maker measures its own way and DJI's figures are best-case, so look for hands-on reports before trusting the gap.
Does the DJI Power 500 have a 12V car outlet?
No. It has two AC outlets, two USB-A ports and two USB-C ports at up to 100W, but no 12V car socket. The AC50B has one, which matters if you run a 12V cooler or tire inflator directly off the station.
