Head-to-head test
EcoFlow RIVER 2 Pro vs DJI Power 500
The DJI Power 500's 1,000W surge ceiling is exactly its 1,000W continuous rating — zero headroom for a startup spike — while the RIVER 2 Pro's 1,600W surge gives it double its 800W continuous rating to absorb the exact jolt the DJI can't.

Spec deltas
The DJI Power 500 is rated for 1,000W continuous with a 1,000W surge ceiling — the same number twice, which means it has zero reserve capacity above its rated output. The RIVER 2 Pro is rated for 800W continuous with a 1,600W surge ceiling, giving it double its own continuous rating in reserve.
That gap matters more than the DJI's lower 800W continuous number might suggest at first glance, because startup spikes, not steady draw, are what actually trip an underbuilt inverter. The RIVER 2 Pro also holds 768Wh against the DJI's 512Wh, a 256Wh edge, at a $140 higher price.
The DJI answers with real advantages of its own: $359 against $499, 25dB against the RIVER 2 Pro's 62dB under load, and a 4,000-cycle rating against 3,000. This isn't a lopsided matchup — it's a genuine tradeoff between headroom and everything else.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
continuous output
Fridge and small AC compressors typically surge 2-3x their steady draw at startup. An appliance rated for a 600-800W steady pull could easily spike past 1,000W on startup, right where the DJI has nothing left to give. The RIVER 2 Pro's 1,600W ceiling on an 800W continuous rating is built with exactly that spike in mind.
The DJI Power 500 is rated for 1,000W continuous with a 1,000W surge ceiling — an identical figure for bothThe RIVER 2 Pro is rated for 800W continuous with a 1,600W surge ceiling — double its continuous rating
Why it mattersAnyone plugging in a compressor-driven appliance should weight the RIVER 2 Pro's surge headroom over the DJI's lower price — a unit that can't absorb the spike doesn't start the appliance at all, regardless of how much steady wattage it's rated for.
The DJI's quiet efficiency is corroborated by testing that found it briefly handled a 1,500W surge above its own 1,000W rating while running a 905W load without issueB3 — a unit that's both quieter and, in practice, more forgiving under real test conditions than its spec sheet alone suggests.
The RIVER 2 Pro is measured at 62dB under load, a figure EcoFlow's own RIVER 2 spec footnotes confirmA2The DJI Power 500 is measured at 25dB
Why it mattersFor anyone running this near where they sleep or work — a desk, a tent, a CPAP at the bedside — the DJI's 25dB is close to silent, where the RIVER 2 Pro's 62dB spike under load is genuinely disruptive.
rated cycles
Even so, the RIVER 2 Pro's 256Wh capacity edge means its cost per lifetime kWh comes out to $0.22 against the DJI's $0.18 — the DJI stays the better raw value despite storing less energy per charge, because the extra cycle life and lower sticker price outweigh the smaller battery.
The DJI Power 500 is rated for 4,000 charge cycles against the RIVER 2 Pro's 3,000The DJI costs $359 against the RIVER 2 Pro's $499, a $140 gap
Why it mattersBuyers optimizing purely for cost-per-kWh with steady, non-surging loads should default to the DJI; the RIVER 2 Pro's premium only earns its keep through the surge headroom, not through raw value.
The specific dimensions that decide these two units — everything else is a tie.
What the Specs Don't Tell You
Selected because: Surge ratio fires as a rare 'advantage' card for the RIVER 2 Pro, the clearest signal on this page.
rated cycles
The surge ratio card is flagged as a genuine advantage for the RIVER 2 Pro, not just an info note — its 1,600W surge ceiling is double its 800W continuous rating, while the DJI Power 500's 1,000W surge ceiling matches its 1,000W continuous rating exactly, leaving zero reserve. That's the single clearest signal on this page.
The noise card cuts the other way and hard: 62dB under load for the RIVER 2 Pro against the DJI's 25dB, a 37dB gap. Stack the two cards together and the matchup reads as an honest tradeoff, not a blowout in either direction — one unit built for surge headroom, the other built for quiet efficiency.
Lifetime Value
Selected because: The DJI wins on cost-per-kWh despite the RIVER 2 Pro's larger battery, worth explaining.
cost / lifetime kWh
The RIVER 2 Pro holds 256Wh more capacity, but the DJI's lower $359 price and 4,000-cycle rating still win on cost per lifetime kWh — $0.18 against $0.22. The extra capacity doesn't pay for itself in pure dollar terms.
Where it does pay off is surge headroom, which the lifetime-value math doesn't capture at all. A unit that can't start the appliance you plug into it delivers zero of its rated lifetime kWh for that use case, regardless of how good the cost-per-kWh number looks on paper.
Portability & Form Factor
Selected because: Both are light, sub-18-lb units; the DJI's minimal included accessories are worth a callout.
weight
Both units are genuinely light — 16.1 lbs for the DJI against 17.2 lbs for the RIVER 2 Pro, essentially a wash at just over a pound apart. Reviewers describe the DJI as easy to transport at that weightB2, and the same is broadly true of the RIVER 2 Pro.
The real gap is in the box, not the shell: one review flagged that the DJI Power 500 ships with only a wall plug, no solar adapter or car-charging cable includedB4. Budget for those separately if you're planning to run it off panels or a 12V outlet.
Brand Trust
Selected because: Cross-brand pair, and DJI is a genuinely new entrant to this category worth framing honestly.
DJI is a genuinely new entrant to power stations — about two years in the category against EcoFlow's much longer track record — but it's leveraging the same support and repair network it built for its drone business, and its LFP cells are rated for 4,000-plus cycles across the lineup. There's no dedicated power-station community yet; DJI discussion mostly lives inside the much larger drone-focused r/dji.
EcoFlow runs the largest community and ecosystem in the category by a wide margin, with faster proprietary charging and the broadest model lineup, but support experiences are mixed and its own October 2025 DELTA Max 2000 recall is worth knowing about. Buying either brand through Costco or Amazon is the safer path for returns.

Conclusion
July 15, 2026
Verdict: the EcoFlow RIVER 2 Pro
The DJI Power 500 is cheaper ($359 against $499), quieter (25dB against 62dB), lighter (16.1 lbs against 17.2 lbs), and rated for more cycles (4,000 against 3,000) — on paper, the easy pick. But its 1,000W surge ceiling is identical to its 1,000W continuous rating, meaning it has no reserve at all for a compressor's startup jolt. The RIVER 2 Pro's 1,600W surge ceiling is double its 800W continuous rating, built with real headroom for exactly that kind of spike, and holds 256Wh more capacity besides. For anyone plugging in a fridge, a CPAP with a heated humidifier, or anything else with a motor, that headroom is the deciding spec. For pure portability and value on steady loads, the DJI is the better $359.

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, RIVER 2 Pro rates 4.5/5 (72nd percentile of 19 Compact-class units), and Power 500 rates 4.4/5 (67th percentile of 19 Compact-class units).

37 Decibels Apart
The RIVER 2 Pro's 62dB under load, confirmed by EcoFlow's own RIVER 2 documentation, is a different category of loud than the DJI Power 500's 25dB. If this is running near where you sleep or work, the noise gap is as decisive as the surge gap.
Zero Reserve Against Double Reserve
The DJI Power 500's surge ceiling and continuous rating are the same number — 1,000W either way. The RIVER 2 Pro's 1,600W surge ceiling is double its 800W continuous rating. For anything with a compressor or motor, that reserve is the spec that decides whether the appliance starts at all.
UPS Speed: standby (<20ms) vs basic standby
The Power 500 switches to battery in 20ms (standby (<20ms)), while the RIVER 2 Pro takes 30ms (basic standby). 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
The Power 500 gives you 16.7 years of warranty per $1,000 spent, vs the RIVER 2 Pro's 14.3 years. That's 1.2× more coverage per dollar. An underrated factor if you're keeping this unit for years.
4,000 Cycles Against 3,000, at a Lower Price
The DJI is both cheaper and rated for more charge cycles before its battery degrades. On raw longevity and price alone, it's the stronger buy — the RIVER 2 Pro earns its higher cost through surge headroom, not durability.

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 across the line, at the quiet end of the category. Fastest wall-charging speeds (~56 min for V2). 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
EcoFlow 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.

EcoFlow RIVER 2 Pro
Owner commentary specific to the RIVER 2 Pro — as opposed to the base RIVER 2 or RIVER 2 Max — is thin online, and this ledger runs to only four entries. The clearest pattern is fan noise: EcoFlow's own spec footnotes confirm the RIVER 2 series can hit 62dB during high-wattage charging or dischargingA2, and one owner documented modding the unit's internals with quieter fans, describing the process as involving cutting away internal plasticA1.
A separate forum post asked whether running the RIVER 2 Pro as a UPS shortens its battery lifeA3, a live question this ledger can't answer. One van-dwelling CPAP user reported running similar solar-charged gear without issue overnightA4, though the report doesn't isolate the RIVER 2 Pro's fan behavior specifically at that light, steady draw.

Who Should Buy Which
Buy the RIVER 2 Pro if you…
- →You're running anything with a compressor or motor — a mini fridge, certain CPAP humidifiers, small power tools — where the 1,600W surge ceiling on an 800W continuous rating is the difference between the appliance starting and the inverter refusing the load.
- →You want the extra 256Wh of capacity and can tolerate the noise, or plan to run it somewhere the 62dB spike under load won't matter.
Buy the Power 500 if you…
- →You're running steady, non-surging loads — laptops, cameras, drone batteries, lighting — where the DJI's zero surge headroom above its 1,000W rating never actually gets tested.
- →You want to spend $140 less and sleep near this thing — 25dB is close to silent, against the RIVER 2 Pro's 62dB under load.
If neither fits
Both fall well short of a full weekend camping trip (about 2,100Wh needed) or an 8-hour multi-appliance blackout (about 1,645Wh needed) — the DJI covers even less of that math than the RIVER 2 Pro, since it starts with less capacity. If that's the real use case, look at a 1,000Wh-plus unit from either brand, or plan on solar topping off through the outage.
The Bottom Line
This is a genuine tradeoff, not a blowout: the DJI Power 500 is cheaper, quieter, and rated for more cycles, but its 1,000W surge ceiling matches its 1,000W continuous rating exactly, with zero reserve for a startup spike. The RIVER 2 Pro's 1,600W surge ceiling on an 800W continuous rating is built with real headroom for that exact jolt.
If anything you're plugging in has a compressor or a motor, take the RIVER 2 Pro's headroom. If your loads are steady — electronics, lighting, cameras — the DJI does the job for $140 less and a fraction of the noise.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Which one can actually run a mini fridge?
The RIVER 2 Pro is the safer bet. Its 1,600W surge ceiling is double its 800W continuous rating, giving it real reserve for a compressor's startup jolt. The DJI Power 500's 1,000W surge ceiling matches its 1,000W continuous rating exactly, leaving nothing in reserve for the same spike.
Is the DJI Power 500 quieter than the RIVER 2 Pro?
Yes, by a wide margin — 25dB against 62dB under load, a 37dB gap. EcoFlow's own RIVER 2 documentation confirms the higher figure during heavy charging or discharging; one RIVER 2 Pro owner found it loud enough to mod the fans.
Does the DJI Power 500 come with solar charging cables?
Not by default — one review noted it ships with only a wall plug, with no solar adapter or car-charging cable included. Budget for those as a separate purchase if solar or 12V charging is part of your plan.
Which is the better value, dollar for dollar?
The DJI Power 500 on raw cost per lifetime kWh — $0.18 against the RIVER 2 Pro's $0.22, driven by its lower $359 price and 4,000-cycle rating. The RIVER 2 Pro's premium only pays off through its surge headroom, not through pure cost efficiency.
Which one lasts longer before the battery degrades?
The DJI Power 500 is rated for 4,000 charge cycles against the RIVER 2 Pro's 3,000, both under 5-year warranties. On pure cycle life, the DJI is rated to outlast the RIVER 2 Pro's battery.
