Anker 535 PowerHouse vs DJI Power 500
Same 512Wh battery both ways, but DJI doubles the output ceiling, rates a UPS switchover Anker doesn't have at all, and still ends up a cent cheaper per lifetime kilowatt-hour despite costing $60 more today.

Spec deltas
The Anker 535 PowerHouse and DJI Power 500 hold the exact same 512Wh — a rare same-battery matchup where capacity never gets to break the tie, so price, output, and cycle life have to.
DJI's output ceiling is double Anker's: 1,000W continuous against 500W, with a 1,000W surge rating on top. Anker's surge rating is 0W, meaning there's no rated headroom above its already-modest continuous number. It also lacks the 20-millisecond UPS switchover DJI carries, so a power blip through the Anker is a real, felt interruption rather than a non-event.
None of that comes free. DJI costs $359 against Anker's $299, a real $60 gap on the number most shoppers see first. But its 4,000-cycle battery outlasts Anker's 3,000-cycle one enough to flip the math: DJI ends up cheaper per lifetime kilowatt-hour, not more expensive, once you count the years.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
solar input
Reviewers measured Anker's real panel draw running under its rated 120W in practiceA4, which stretches that 6.1-hour figure further out in the field. DJI's 300W ceiling has that much more room to absorb the same shortfall and still finish sooner.
Anker 535 rated for 120W solar input; DJI Power 500 rated for 300WAnker's rated solar recharge from empty takes 6.1 hours
Why it mattersAnyone charging primarily off solar — van life, remote job sites, extended outages — should weight DJI's input ceiling heavily. Plug-in campers with a wall outlet nearby won't feel this gap at all.
rated cycles
That's why DJI's cost per lifetime kilowatt-hour comes out lower — 18 cents against Anker's 19 — even though Anker wins the number everyone compares first. The extra cycles don't just add years of use, they change which unit is the better deal per watt-hour delivered.
Anker 535 costs $299 with 3,000 rated cycles on 512WhDJI Power 500 costs $359 with 4,000 rated cycles on the same 512Wh
Why it mattersBuyers comparing these two on shelf price alone are reading the wrong number. Over years of ownership, the cheaper-to-own unit is DJI.
continuous output
DJI's 1,000W surge figure is also just its continuous rating restated, so neither unit has true burst headroom above its steady number. But DJI's steady number starts at double Anker's. A coffee maker running with a laptop, or a hair dryer on low, clears 500W and simply has nowhere to go on the Anker.
Anker 535 rated for 500W continuous output with 0W rated surgeDJI Power 500 rated for 1,000W continuous with a 1,000W surge rating
Why it mattersIf the reader's use case ever touches anything past 500W steady draw, Anker isn't the weaker option here — it's disqualified outright.
Pair that with DJI comfortably exceeding its own rated surge ceiling under test loadB3, and the Power 500 reads like a unit with headroom DJI simply didn't bother rating conservatively on the spec sheet.
DJI Power 500 rates a 20ms switchover; Anker 535 rates noneDJI ran a real load and briefly exceeded its rated surge ceiling in testing without failingB3
Why it mattersAnyone protecting a desktop, router, or NAS from outages should treat DJI's UPS rating as a hard requirement Anker can't meet at any price.
The specific dimensions that decide these two units — everything else is a tie.
PowerScore Breakdown
Selected because: DJI's power score beats Anker's on the identical battery size — the output and surge gap shows up here first
overall power score
Same 512Wh tank, but DJI's score comes in well ahead, and the reason is almost entirely the output ceiling: 1,000W continuous against Anker's 500W, with a 1,000W surge rating Anker doesn't have at any level.
Capacity ties this pairing. Everything the power score measures beyond capacity favors DJI outright.
Lifetime Value
Selected because: despite costing $60 more, DJI's higher cycle count makes it the cheaper unit per lifetime kWh — the crossover buyers need to see
cost / lifetime kWh
Eighteen cents a kilowatt-hour for DJI against nineteen for Anker — a gap that only opens up because DJI's 4,000-cycle battery outlasts Anker's 3,000-cycle one by enough to offset the $60 price difference.
Anker still wins the number most people actually compare: $299 is $60 cheaper today, full stop, and that's a legitimate reason to buy it if the upfront cost is what's tight.
What the Specs Don't Tell You
Selected because: UPS protection, noise disclosure, and solar recharge speed all fire for this pair and split cleanly toward DJI
rated cycles
Three flags fire here and all three land on DJI: it's the only one rated for UPS-grade switchover, the only one with a published noise figure — Anker's isn't disclosed at all — and the one with the faster rated solar recharge.
None of these are marketing flourishes. They're gaps in what Anker is willing to publish, not just gaps in performance.
Brand Trust
Selected because: Anker's declining SOLIX support track record against DJI's inherited drone-business support network is worth surfacing on a purchase this size
Anker is a known, trusted consumer electronics brand, but recent reports describe AI-driven support responses and complicated return logistics for its heavier SOLIX units — a decline from the brand's historically excellent standard. DJI is new to power stations, about two years in, but inherits a global repair network built for its drone business, with no power-station-specific track record either way yet.
Neither history is disqualifying. Anker is the safer bet if brand longevity in this specific category matters most; DJI is the safer bet if the parent company's repair infrastructure matters more than a newer product line's growing pains.

Conclusion
July 14, 2026
Verdict: the Power 500
Identical capacity means this isn't decided by runtime — every scenario percentage matches exactly between the two. It's decided by everything else: DJI's 1,000W continuous output against Anker's 500W, a 20ms UPS-rated switchover Anker doesn't publish, 4,000 cycles against 3,000, and a lower cost per lifetime kilowatt-hour despite the higher sticker price. Anker's real case is the $299 price tag itself. If that's the constraint, take it. Otherwise, the Power 500 is the more capable unit on the same battery.

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, 535 PowerHouse rates 3.5/5 (11th percentile of 19 Compact-class units), and Power 500 rates 4.4/5 (67th percentile of 19 Compact-class units).
How the class ranking is computed →Test Notes & Caveats
Hidden gotchas and advantages we spotted that you won't find on the product page.
535 PowerHouse: Slow Even at Its Rated Number
A full recharge at the rated 120W takes 6.1 hours. Real-world panel draw runs under that rated figure, so budget for longer if you're relying on solar rather than a wall outlet.
535 PowerHouse: No App Control
Without app control, you have to physically walk to the 535 PowerHouse to check battery level, adjust settings, or monitor power draw. The Power 500 lets you do all that from your phone, including getting low-battery alerts.
Only One of These Rates a UPS Switchover
DJI's 20-millisecond switchover is fast enough that a desktop or router typically won't notice the outage. Anker rates no switchover time at all, so a power blip through the 535 is a real, felt interruption.
1,000 More Cycles Adds Up to a Cent a Kilowatt-Hour
DJI's 4,000-cycle rating against Anker's 3,000 is why the Power 500 ends up cheaper per lifetime kilowatt-hour despite its higher price — 18 cents against 19.
Anker Doesn't Publish a Noise Rating
DJI lists 25dB under load. Anker's 535 PowerHouse has no published decibel figure at all, which makes it hard to know what you're getting if you plan to run it near where you sleep or work.

Brand trust
Anker
Ecosystem
7-8 SOLIX portable power stations across C-series (compact) and F-series (flagship), plus the X1 home energy system
Support
US-based support. Historically known for incredible no-hassle replacements, but recent reports describe AI-driven support agents giving generic responses and complex return logistics for heavy units (hazmat shipping). The Anker brand reputation is still strong, but SOLIX-specific support quality is trending down.
Community
Moderate — active Reddit (r/Anker, r/AnkerSOLIXCommunity) and growing. Benefits from Anker's massive consumer electronics brand awareness.
App experience
Rated 4.5/5 iOS (~1,100 ratings) · 4.3/5 Android
Unique strength
Anker's parent-brand trust from decades in consumer electronics is real, and its newer SOLIX lineup posts some of the best dollar-per-watt-hour value in the category.
Worth knowing
Support quality on SOLIX units is reportedly trending down from Anker's historically excellent standard — AI-driven responses and complicated return logistics for heavier units are recent complaints.
DJI
Ecosystem
New entrant (2024) — 4 power station models: Power 500, Power 1000 V2, Power 1000 Mini, Power 2000
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
DJI brings hundreds of battery patents from its drone business and builds some of the quietest units in the category, with support inherited from a global drone repair network.
Worth knowing
DJI has only about two years of track record in power stations, with no expansion battery ecosystem yet across any of its four models.
Analyst note
Anker is the safer bet on brand history in this specific category; DJI is newer here but backed by a much larger, established parent company's repair infrastructure. For a $299-to-$359 purchase, neither risk is severe — this one is closer than the spec sheet alone suggests.
Growth path
535 PowerHouse
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 120W of solar. Limited to a single portable panel.

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 535 PowerHouse 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.
Anker 535 PowerHouse
The 535 PowerHouse's LiFePO4 cells are rated for 3,000-plus cycles and roughly a 10-year lifespan, backed by a 5-year warrantyA1, and testers clocked 89% round-trip efficiency, staying stable and cool while delivering its full 500W AC outputA3. At 16.5 lbs it's compact for a 512Wh unit and comes with four AC ports, three USB-A, a USB-C, and a car outletA2. The honest catch: AC charging to 80% takes about 2.5 hours, and while it's rated for 120W solar, real-world panel input runs under that number in practice, so don't count on the rated speed if you're relying on the sunA4.

DJI Power 500
The Power 500's automotive-grade LFP cells are rated for 3,000 to 4,000 cycles — roughly a decade of use — and in testing it held up under a heavy load while briefly exceeding its own rated surge ceiling, with reviewers finding it more efficient than DJI's own larger Power 1000B1B3. It's also the lighter unit at just 7.3 kg, easy to move around a campsite or a garageB2. The one honest gap: it ships with just a wall charging plug — no solar adapter or car-charging cable included — so budget for those separately if you're not charging exclusively from an outletB4.

Who Should Buy Which
Buy the 535 PowerHouse if you…
- →Buyers who want the lowest sticker price on a 512Wh unit and won't push past 500W continuous
- →Anyone who already owns Anker gear and values the brand's broader consumer-electronics support network
- →Buyers fine without app control or a UPS-rated switchover
Buy the Power 500 if you…
- →Anyone running anything past 500W steady — a coffee maker with a laptop, a hair dryer, small power tools
- →Buyers who want UPS-grade protection for a desktop, router, or NAS during outages
- →Drone pilots and DJI ecosystem owners who want fast charging and a quieter, 25dB-rated unit
If neither fits
Anyone planning a real weekend campsite trip, an extended blackout, or running a fridge for more than a few hours. Both units cap out at 512Wh, well under what those jobs need — look at something in the 1,000Wh-plus class instead.
The Bottom Line
Same 512Wh battery, but DJI doubles the output ceiling, rates UPS-grade switchover Anker doesn't have, and still ends up a cent cheaper per lifetime kilowatt-hour despite the $60 higher price tag.
Take the Anker only if $299 is the hard constraint and 500W steady is genuinely enough — everything else on this page points to the Power 500.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the Anker 535 PowerHouse or DJI Power 500 better for running a fridge?
Neither is really built for it. Both top out at 512Wh, which falls well short of what a compressor fridge running for hours needs. If a fridge is the job, look at a 1,000Wh-plus unit instead of either of these.
Which one charges faster from solar?
DJI, by a wide margin. Its 300W solar rating is more than double Anker's 120W, and Anker's real-world panel draw tests below its rated number, stretching a full solar recharge out further than the 6.1-hour rated figure in practice.
Does either have UPS or backup power switchover?
Only the DJI Power 500, rated for a 20-millisecond switchover — fast enough that a desktop or router typically doesn't register the outage. Anker's 535 PowerHouse has no switchover rating at all.
Which is cheaper to own over its lifetime?
DJI, despite costing $60 more upfront. Its 4,000-cycle battery works out to 18 cents per lifetime kilowatt-hour against Anker's 19 cents on a 3,000-cycle battery, because the extra cycle life outweighs the extra sticker price.
