Head-to-head test
EcoFlow RIVER 3 vs Jackery Explorer 300 v2
The RIVER 3 is $60 cheaper and shrugs off rain at IP54, but the v2 answers with 43 more watt-hours, 1,000 more cycles, a faster UPS, and 417 more kWh over its life, so you're deciding whether ruggedness and $60 beat capacity and longevity.

Spec deltas
The Explorer 300 v2 wins this one on capacity and longevity, but only just. It holds 288Wh to the EcoFlow RIVER 3's 245, 43 more watt-hours, and it's rated for 4,000 charge cycles against 3,000.
Those two facts compound. Over their lifetimes the v2 delivers 1,152 kWh against the RIVER 3's 735, 417 more, which is why the engine calls it cheaper to own at $0.23 per kWh against $0.28, despite costing $60 more up front. It also switches to backup faster, sub-10ms against sub-20ms, and outlasts the RIVER 3 on every load in the runtime table.
The RIVER 3's counter is genuinely good. It's $60 cheaper at $209, it's rated IP54 for dust and rain the v2 doesn't claim, it publishes a sub-30dB noise floor, and it has an app. Give up 43Wh and it's the cheaper, tougher, quieter box. This comes down to which you value more: the v2's capacity and lifespan, or the RIVER 3's price and ruggedness.
What the Numbers Reveal
Each conclusion stated first — the numbers behind it on one line, the full analysis below.
rated cycles
That's why the pricier v2 is the cheaper unit to own, $0.23 per lifetime kWh against $0.28. You pay $60 more at the register and get 417 kWh more energy before the battery retires, which is the definition of paying less per unit of the thing you're actually buying.
The v2 holds 288Wh and is rated for 4,000 cycles; the RIVER 3 holds 245Wh at 3,000 cyclesThe engine multiplies those out to 1,152 lifetime kWh for the v2 against 735 for the RIVER 3
Why it mattersBuyers who'll cycle the unit regularly for years should read past the $60 sticker gap; the v2 returns it and then some over the battery's life.
Capacity
For an overnight or a long workday away from an outlet, the v2's extra hour or two of headroom is the difference between reaching morning and rationing the last 10%. The RIVER 3 isn't far behind, but it is behind on every line of the table.
The v2's 288Wh runs a 40W CPAP about 0.9 hours longer than the RIVER 3's 245WhOn a 15W phone charge the v2 runs about 2.4 hours longer
Why it mattersIf you run the unit close to empty overnight or over a full day, the v2's capacity buys margin the RIVER 3 can't match.
IP54 means the RIVER 3 survives a dusty tailgate or a drizzle the v2's spec sheet won't promise to, and it does it for $60 less while telling you it runs under 30dB. For outdoor and jobsite use where the box takes weather and knocks, that resilience outweighs 43 watt-hours.
The RIVER 3 is rated IP54 for dust and water resistance; the v2 makes no ingress-protection claimThe RIVER 3 lists at $209 against the v2's $269 and publishes a sub-30dB noise floor
Why it mattersCampers, tailgaters, and jobsite users who'll expose the unit to dust and rain should take the RIVER 3 despite the smaller battery.
The specific dimensions that decide these two units — everything else is a tie.
Lifetime Value
Selected because: The v2 is pricier to buy but cheaper to own; the crux of a close verdict.
cost / lifetime kWh
The v2 is the pricier box to buy and the cheaper one to own. Its 288Wh at 4,000 cycles pencils out to 1,152 lifetime kWh; the RIVER 3's 245Wh at 3,000 cycles to 735, a 417-kWh gap that turns the v2's $60 higher price into a lower $0.23 per lifetime kWh against $0.28.
The sticker favors the RIVER 3; the meter favors the v2. Which number rules depends only on how long you keep it: bail in two years and the RIVER 3 saved you $60, run it for a decade and the v2 gave you 417 kWh more for that same $60.
Runtime: Will It Power Your Gear?
Selected because: Same inverter, so the 43Wh gap shows purely as longer runtime for the v2 on every load.
Same 300W inverter on both, so nothing here is about what they can run, only how long. The v2's 43 extra watt-hours give it the longer number on every load: about 0.9 hours more on a CPAP, 2.4 more on a phone charge.
None of it is dramatic, but it's all in one direction. Over a full night or workday, that margin is the difference between coasting to the alarm and watching the last 10% tick down.
What the Specs Don't Tell You
Selected because: Cards split: v2 takes cycle life and UPS, RIVER 3 takes app and disclosed noise.
rated cycles
The cards split cleanly. The v2 banks its 4,000-cycle rating and sub-10ms UPS; the RIVER 3 answers with the app the v2 lacks and a published sub-30dB noise floor where the v2 discloses nothing. Warranties tie at five years.
The one advantage that doesn't render as a card but matters most in the field is IP54, the RIVER 3's dust-and-water resistance, which the v2 doesn't claim. On a spec sheet it's a footnote; on a wet campsite it's the whole ballgame.
Brand Trust
Selected because: Cross-brand pair; EcoFlow's ecosystem/app vs Jackery's retail reach, both with support caveats.
EcoFlow runs the deepest ecosystem and the most active community in the category, and its app is among the best-rated, though it's worth knowing about the October 2025 DELTA Max recall and a since-paused experiment with app-feature paywalls.
Jackery counters with the widest retail presence, easy to buy at Costco and easy to return, offset by the weakest app of the majors and warranty-claim complaints. For either brand, buying from a retailer with a strong return desk is the smart hedge.

Conclusion
July 18, 2026
Verdict: the Jackery Explorer 300 v2
A slight edge to the Explorer 300 v2, but this one is close. The v2 holds 288Wh to the RIVER 3's 245, 43 more, and turns that plus a 4,000-cycle rating into 1,152 kWh of lifetime energy against 735, which is why it's the cheaper unit to own at $0.23 per kWh against $0.28. It also fails over faster, sub-10ms against sub-20ms, and runs longer on every load in the table. The honest catch is real and it's the RIVER 3's whole case: it's $60 cheaper at $209, it's IP54-rated against dust and rain where the v2 makes no such claim, it publishes a sub-30dB noise floor, and it adds app control. Want the rugged, quieter, cheaper-to-buy box and can spare 43Wh, and the RIVER 3 is the easy pick. Want the most capacity and the longest life per dollar, and it's the v2 by a nose.

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, RIVER 3 rates 4.1/5 (48th percentile of 22 Personal-class units), and Explorer 300 v2 rates 4.8/5 (90th percentile of 22 Personal-class units).

The RIVER 3 Has an App; the v2 Doesn't
EcoFlow gives you phone monitoring and control the Jackery leaves out entirely. If checking state of charge remotely matters, it's a point for the RIVER 3.
Sub-10ms vs Sub-20ms
The v2 switches to battery about twice as fast as the RIVER 3. Both protect a router fine; the v2's margin is for more sensitive electronics.
Warranty: No Difference
Both units carry the same 5-year warranty, so coverage isn't a tiebreaker here.
4,000 Cycles vs 3,000
The v2's cells outlast the RIVER 3's by a third in rated charge cycles, the backbone of its lower lifetime cost per kWh.
Only One of These Names Its Noise
The RIVER 3 publishes a sub-30dB figure; Jackery lists nothing for the v2. Disclosure isn't the same as being quieter, but it's the only unit here you can plan a quiet room around.

What Owners Report
Patterns from published owner reports and long-term reviews — every claim cited to its source below.
EcoFlow RIVER 3
The RIVER 3's story is a clean generational upgrade over the RIVER 2: reviewers highlight sub-30dB operation EcoFlow frames as quieter than a library, plus IP54 water resistance, a faster UPS, and a lighter shellA1A2. Coverage recommends it as the better buy for most in 2026, for camping, van life, or home UPS backup where durability and noise matterA3.
It's framed as holding more capacity and weighing less than the RIVER 2 while costing less, a rare strict upgrade on the same platformA4. The caveat is that most of this is comparative against the older unit rather than long-run ownership data, so treat it as directional.
“The RIVER 3 operates under 30 dB — EcoFlow calls it 'whisper quiet,' quieter than a library — one of the most significant upgrades over the louder RIVER 2.”

Jackery Explorer 300 v2
The v2's positive field notes are all grab-and-go: one reviewer praised how fast it charges and how light it is, a strong starting point for road trips and topping off phones, cameras, and dronesB2, and an event-rental operator liked it enough to buy a secondB1. It's a thin record for a new SKU, but the early read is friendly and portable.
The recurring gripe is accessories, not the battery: a proprietary barrel-style DC solar jack that needs an extra adapter to charge from a panelB4, and a 12V car cable pictured on the box but missing inside itB3. Neither is a battery problem, but both are the kind of first-owner friction a longer track record would usually iron out.
“Uses the unit for an event rental business and made it a repeat (second) purchase — likes not having to worry about finding electrical outlets nearby at events.”

Who Should Buy Which
Buy the RIVER 3 if you…
- →You'll take it outside a lot; IP54 lets it handle dust and drizzle the v2 won't promise to survive.
- →You want the lower price and an app: $209 and phone control, for giving up 43Wh.
- →You want a quieter, stated noise floor near a campsite or desk; the RIVER 3 publishes sub-30dB where the v2 says nothing.
Buy the Explorer 300 v2 if you…
- →You want the most capacity and the longest life per dollar: 288Wh, 4,000 cycles, and $0.23 per lifetime kWh.
- →You'll run it close to empty overnight or over a full workday, where the extra 43Wh buys real margin.
- →You'd use the faster sub-10ms UPS behind sensitive electronics.
If neither fits
If the job is a weekend camp (about 2,100Wh) or an 8-hour blackout (about 1,645Wh), neither 245Wh nor 288Wh is remotely enough; both cover well under half a night. These are device boxes. For appliance backup, step up to a 1,000Wh-plus unit from either brand.
The Bottom Line
Two good small boxes, split down the middle. The Explorer 300 v2 is the capacity-and-longevity pick: 288Wh, 4,000 cycles, 417 more kWh over its life, and a lower $0.23 per kWh to own. It earns its $60 premium if you'll keep it for years.
The RIVER 3 is the value-and-ruggedness pick, $60 cheaper, IP54 against dust and rain, quieter on paper, and app-controlled, for the price of 43 watt-hours. Buy the v2 for the most battery per dollar over time; buy the RIVER 3 if you want a tougher box for less today. Neither is a mistake.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
EcoFlow RIVER 3 or Jackery Explorer 300 v2?
Close call. The v2 holds more (288Wh vs 245), lasts longer (4,000 cycles vs 3,000), and is cheaper to own at $0.23 per lifetime kWh. The RIVER 3 is $60 cheaper up front, IP54-rugged, quieter on paper, and has an app. Pick the v2 for capacity and lifespan, the RIVER 3 for price and ruggedness.
Is the Jackery worth $60 more than the RIVER 3?
If you'll use it for years, yes; it delivers 417 more kWh over its life and costs less per kWh as a result. If you mostly want a cheap, tough box for occasional outdoor use, the RIVER 3's lower price and IP54 rating make it the better value.
Which is better for camping?
The RIVER 3, for most campers. Its IP54 dust-and-water resistance is the spec that matters when a power station lives outside, and it's $60 cheaper. Choose the v2 only if you need the extra 43Wh of overnight headroom more than the weather resistance.
Which lasts longer on a charge?
The v2, on every load. Its 288Wh runs about 0.9 hours longer on a CPAP and 2.4 hours longer on a phone charge than the RIVER 3's 245Wh. The gaps are modest but consistent.
Which is the better UPS?
The v2, narrowly; it fails over in under 10ms against the RIVER 3's under 20ms. Both are fast enough for a router or modem, so the v2's quicker switchover only matters for more transfer-sensitive gear.
