Head-to-head test
BLUETTI AC70 vs DJI Power 500
The AC70's higher price buys half again the battery and a published surge ceiling twice as high; the Power 500 answers with 6.4 lb less to carry and a longer cycle rating, which only wins where the unit sits on a nightstand or rides in a drone bag.

Spec deltas
The BLUETTI AC70 costs $60 more than the DJI Power 500 and puts 768Wh in the box against 512Wh. That's half again the battery, at a lower cost per watt-hour on the sticker. At this size the extra 256Wh isn't padding: on our 670Wh tailgate list, it's the difference between running out 17Wh from the end and running out 235Wh from it.
The Power 500 hits back where it can. It weighs 16.1 lb to the AC70's 22.5, it's rated for at least 4,000 cycles to the AC70's 3,000, and it costs a cent less per lifetime kWh. DJI also rates it far quieter, but the two makers don't publish noise the same way, so treat that as a reason to find a hands-on report, not a gap to bank on.
Both inverters run 1,000W continuously, and only the AC70 publishes headroom above that, at 2,000W. Add the 12V car outlet the DJI lacks and the AC70 is the better box for most people at a modest premium. The honest catch is the one you'd guess: it's the heavier unit to haul, and its fan ramps up once you push heavier output through itA1.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
Capacity
That's what the $60 premium actually buys: not a bigger number on a spec sheet, but the day you planned finishing instead of stopping early. Neither unit is built for a blackout or a weekend camp, so the only rows that matter are the medium ones, and on the tailgate and the workday the AC70 gets far closer to done.
AC70: 768Wh, about 653Wh usable after the 85% deratePower 500: 512Wh, about 435Wh usableTailgate Party needs 670Wh: AC70 17Wh short, Power 500 235Wh shortRemote Workday: AC70 covers 72%, Power 500 48%
Why it mattersIf your typical day draws more than about 435Wh, the Power 500 will make you ration and the AC70 mostly won't.
weight
So the lighter box only wins if you never need more than its battery, which is a real buyer (the one-night CPAP user, the drone pilot topping off packs) but a narrow one. And for car camping, the missing 12V outlet means a 12V fridge on the Power 500 has to run through its AC adapter instead of plugging straight in.
AC70: 22.5 lb for 768WhPower 500: 16.1 lb for 512WhAC70 has one 12V car outlet; the Power 500 has none
Why it mattersCarry-first buyers with small loads should take the Power 500; anyone running a 12V fridge from the back seat should not.
Compressors and motors briefly pull two to three times their running watts, so a start that spikes anywhere between 1,000W and 2,000W is covered on the AC70's spec sheet and not on the DJI's. One reviewer's test suggests the Power 500 has more in reserve than DJI claimsB3, which is encouraging, but a single test isn't a rating you can plan a fridge around.
AC70: 1,000W continuous, 2,000W surge publishedPower 500: 1,000W continuous, no surge published above 1,000WOne review saw the Power 500 briefly hold a 1,500W surgeB3
Why it mattersAnyone starting a compressor fridge or power tools should buy the unit that puts its surge in writing, and that's the AC70.
cost / lifetime kWh
Those two effects nearly cancel on money, landing a cent apart per lifetime kWh in the DJI's favor. The 4,000-cycle rating is a real edge in years, but it doesn't make the Power 500 the better buy, because what you pay per unit of energy over the pack's life is a dead heat.
AC70: 3,000 cycles x 768Wh = 2,304 kWh lifetime, $0.16 per lifetime kWhPower 500: 4,000 cycles x 512Wh = 2,048 kWh lifetime, $0.15 per lifetime kWhDaily use: 11 years for the Power 500, 8.2 for the AC70
Why it mattersDon't let the bigger cycle number decide this one; decide on how much battery you need each day.
The specific dimensions that decide these two units — everything else is a tie.
Your Life, Your Pick
Selected because: The AC70 finishes within 17Wh of a 670Wh tailgate the Power 500 misses by 235Wh, which is where its extra 256Wh shows up.
Five of the six rows come back neither, and that's the honest headline: a blackout list needing 1,645Wh and a campsite needing 2,100Wh are jobs for a much bigger station, not a choice between these two. The rows worth arguing about are the medium ones. The AC70 misses the tailgate by 17Wh, one appliance unplugged a little early; the Power 500 misses it by 235Wh. The remote workday splits the same way, 72% covered against 48%.
The CPAP row goes to the Power 500, and for the bedside that's a fair call: both cover the 320Wh night, and the DJI does it in the smaller, lighter box. Just know what you're trading. The AC70 has 333Wh left over in the morning, enough for a second night; the Power 500 has 115Wh, which isn't.
PowerScore Breakdown
Selected because: Both run 1,000W continuously, but only the AC70 publishes surge headroom, at 2,000W.
overall power score
The AC70 is the higher-scoring of the two, carrying a battery half again as big and a surge ceiling of 2,000W where the Power 500 publishes none above its 1,000W. Plug in a laptop, lights and a fan and you'll never see the difference.
Start a compressor and you might. A motor's first second is where inverters trip, and the AC70 is the one with headroom in writing. The Power 500 may well have more than DJI admits, but you'd be buying it on faith.
Portability & Form Factor
Selected because: The Power 500's strongest card is its 16.1 lb, 6.4 lb under the AC70.
weight
At 16.1 lb the Power 500 is a one-hand grab from the car to the tent; the AC70's 22.5 lb is still a single carry, just one you notice. If the box moves more often than it drains, that's a real reason to take the DJI.
But run the division before paying for lightness. The AC70 carries about 34Wh per pound and the Power 500 about 32, so the DJI isn't lighter because it's cleverer. It's lighter because it holds less.
Lifetime Value
Selected because: The Power 500's 4,000-cycle rating and the AC70's bigger pack land a cent apart per lifetime kWh.
cost / lifetime kWh
The Power 500 wins this section by a penny: $0.15 per lifetime kWh against $0.16. Its pack is rated for 4,000 cycles to the AC70's 3,000, which works out to 11 years of daily use against 8.2.
The AC70 claws it back on size. Each of its cycles moves 768Wh instead of 512Wh, so over its rated life it delivers 2,304 kWh to the DJI's 2,048. A penny apart is a tie, and a tie on longevity sends the decision back to how much battery you need on a given day.

Conclusion
October 11, 2026
Verdict: the BLUETTI AC70
Take the AC70. The extra $60 buys 256Wh more battery, a published 2,000W surge ceiling against the Power 500's 1,000W, a 12V car outlet the DJI doesn't have, and 500W of solar input against 300W, and it still carries the lower cost per watt-hour on the sticker. The Power 500 is 6.4 lb lighter and rated for more cycles, but its cost per lifetime kWh lands only a cent under the AC70's, so longevity doesn't buy it the win. Pick the DJI when light beats large: one night of CPAP at the bedside, or a drone kit that already runs on DJI's SDC ports.

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, AC70 rates 4.8/5 (89th percentile of 20 Compact-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 Rulebooks
BLUETTI rates the AC70 at 45dB and DJI rates the Power 500 at 25dB, and DJI's figures across its range are best-case numbers. The two makers don't measure the same way, so the difference isn't one you can count on hearing. At a light bedside load the question is open on both; check a hands-on report before either goes next to a pillow.
AC70: Power Lifting to 2,000W
The AC70 has BLUETTI's Power Lifting mode, which runs a resistive appliance rated up to 2,000W from its 1,000W inverter. It does that by delivering less power than the appliance asks for, not more than the inverter has: the heater still works, it just heats more slowly. Two things follow. 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; for motor loads the figure to read is the AC70's separate 1,500W surge peak, not this one. And it is not a reason to size down, because running a load that big from 768Wh is a short session either way. Genuinely useful if a heater or a kettle is why you're buying; beside the point otherwise. The Power 500 publishes no equivalent.
Only One Puts Its Surge in Writing
Both run 1,000W continuously. The AC70 is rated to 2,000W for startup spikes; the Power 500 publishes no surge figure above its 1,000W. Motors and compressors briefly draw two to three times their running watts, so a start that lands between 1,000W and 2,000W is covered on the AC70's spec sheet and not on the DJI's. Plan the Power 500 at face value.
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.
More Cycles, Less Energy
The Power 500 is rated for at least 4,000 cycles against the AC70's 3,000, which reads as 11 years of daily use against 8.2. But a cycle is 512Wh on the DJI and 768Wh on the BLUETTI, so over the rated life the AC70 delivers about 2,304 kWh to the Power 500's 2,048. Either pack, at its rating, drops to roughly 80% capacity rather than quitting.

Analyst note
Both units have similar long-term ownership costs ($0.16/kWh vs $0.15/kWh). The price difference is what you see on the sticker — neither is a hidden bargain or rip-off. 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 AC70 still delivers more over its shorter horizon (2,304 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 most inconsistent support in the space. Heavily email-based with China timezone delays. Some users get smooth, efficient service; others report weeks of troubleshooting runarounds, being offered discounts on new units instead of repairs, and confusing third-party purchase claim processes. Buying direct from Bluetti's website tends to produce better support outcomes.
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
Among the best capacity-to-price ratios available — several Elite and Apex units are the lowest $/Wh in the catalog. Widest product diversity including industry-firsts like sodium-ion cold-weather units and dual solar+alternator vehicle hubs. LFP across the rest of the range, though rated cycle life spans 2,500 (EB3A) to 6,000, and it varies WITHIN the Elite range rather than tracking it — the Elite 300 and Elite 200 V2 are rated 6,000 while the Elite 30 V2, Elite 10 Mini, Elite 320 and Elite 400 are rated 3,000+ and the Elite 100 V2 4,000+, so check the specific model. Dual-voltage (120V/240V) in flagships.
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
BLUETTI brings the longer power-station track record and the most uneven support reputation in the category, which is why buying direct matters. DJI brings a repair network built for its drones and very little power-station history. At this size, neither brand fact outweighs the hardware: the battery and surge gap does the deciding.
Growth path
AC70
FIXED CAPACITYFixed at 768Wh, with no expansion — so size it for your needs up front rather than planning to add capacity later.
Accepts up to 500W of solar. Suitable for a 1-2 panel setup.
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 AC70 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 AC70
Coverage of the AC70 comes from reviewers rather than long-term owners, and they line up on the same strengthsA0: it's compact enough to carry at about 22 lbA4, and Turbo mode refills it from the wall in under an hour, with pass-through charging that keeps devices running while it tops upA2. Testing turned up no faults, and the warranty runs to five years when bought direct from BLUETTIA3.
The recurring caveat is the fan. It stays quiet under light loads and ramps up past heavier output to roughly an old laptop working hardA1. That's reassuring for a small overnight draw and worth knowing if you plan to run it near its 1,000W limit in a small room.
“Under light loads the fan is quiet, but push past heavier output and it ramps up to a noticeable but not obnoxious level — comparable to an old laptop or gaming PC under load.”

DJI Power 500
It's easy to move at about 7.3 kgB2, and reviewers found it stronger in practice than its spec sheet: one test ran a 905W load, saw it briefly hold a 1,500W surge, and found it more efficient than DJI's own larger Power 1000B3. DJI pitches its cells at roughly a ten-year lifespanB1.
The catch one reviewer flagged is the box contents: a wall plug and nothing else, so a solar or car-charging cable is an extra purchaseB4. Field data is thinner than for the AC70, since this is a recent arrival from a drone company and the coverage comes from review sites rather than long-term ownersB0.
“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.”

Who Should Buy Which
Buy the AC70 if you…
- →The tailgater or remote worker whose day runs past 435Wh: the AC70 gets within 17Wh of a 670Wh evening the Power 500 misses by 235Wh.
- →The car camper running a 12V fridge off the back seat, since the AC70 has the 12V car outlet and the Power 500 has none.
- →Anyone starting a compressor or power tool whose startup spike lands between 1,000W and 2,000W, where only the AC70 publishes headroom.
- →The solar user who wants 500W of panel input rather than 300W.
Buy the Power 500 if you…
- →The CPAP user who wants the lightest box beside the bed and recharges every day: a 320Wh night fits with 115Wh to spare.
- →The drone pilot already carrying DJI gear, whose SDC ports fast-charge DJI's own kit.
- →Anyone who carries the unit more than they drain it, and for whom 16.1 lb against 22.5 lb is the whole decision.
If neither fits
Close this tab if you're shopping for an 8-hour blackout or a weekend campsite on one charge: those lists need 1,645Wh and 2,100Wh, and even the AC70 covers only about 40% and 31% of them. For the blackout list, look at a station with roughly three times the AC70's battery.
The Bottom Line
The AC70 is the better buy. Its premium buys half again the battery, and on the medium-sized days these units are actually for, that's the difference between finishing the evening and rationing it. A surge rating in writing and a 12V car outlet come along with it.
The Power 500 is the right box only when light beats large: one night at the bedside, or a bag of DJI drone batteries. For everyone else, carry the extra 6.4 lb and take the AC70.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the BLUETTI AC70 worth the extra money over the DJI Power 500?
For most people, yes. The extra $60 buys 256Wh more battery, a published 2,000W surge rating against 1,000W, a 12V car outlet and more solar input. The Power 500 is the better pick only if weight matters more than capacity.
Which is better for a CPAP, the AC70 or the Power 500?
Both cover a 40W CPAP night, and our CPAP row goes to the Power 500 for being the smaller, lighter box at the bedside. The trade is margin: the AC70 has enough left in the morning for a second night, while the Power 500 doesn't. One review found the AC70's fan quiet under light loads, and DJI's lower noise rating is published differently from BLUETTI's, so neither figure settles which is quieter at a CPAP's draw.
Can the DJI Power 500 handle a fridge or power tool startup?
It runs 1,000W continuously but publishes no surge rating above that, while the AC70 is rated to 2,000W for startup spikes. One review saw the Power 500 briefly hold 1,500W, which is encouraging, but it isn't a rating. For anything with a compressor or motor, the AC70 is the safer plan.
Can you add an expansion battery to the AC70 or the Power 500?
No. Both are fixed at their size, 768Wh for the AC70 and 512Wh for the Power 500. Buy the capacity you need now, because outgrowing either means buying a second unit.
Does the DJI Power 500 charge from solar panels?
Yes, up to 300W, but DJI's stations need a separate DJI adapter before a panel plugs in, and one review notes it ships with only a wall plug. The AC70 takes up to 500W of solar. If panels are part of the plan, budget for the DJI's adapter or take the BLUETTI and its higher input.
