Spec deltas
We run six load profiles against every station, from a CPAP night to a van-life day. The RIVER 2 Pro finishes one of them. The Explorer 1500 v2 finishes three. The other three are beyond both.
The Jackery gets there with twice the battery and a much bigger inverter, the part that turns stored energy into household AC. It runs 2,000W to the EcoFlow's 800, and a space heater sits between those two numbers. For a cabin like mine, the next thing I'd check is solar input, and the Jackery takes nearly twice as much.
The RIVER 2 Pro answers with size and price. It weighs 17.2 lb to the Jackery's 32, costs $600 less, and its capacity costs less per watt-hour. If your list is a CPAP, a phone and a bedside lamp, it covers the night with plenty left over.
What the Numbers Reveal
Each conclusion stated first β the numbers behind it on one line, the full analysis below.
continuous output
Doubling the battery is the smaller part of what the extra money buys. The inverter is two and a half times the size, so anything from 800W to 2,000W is inside the Jackery's rating and past the RIVER's.
RIVER 2 Pro: 768Wh at $349Explorer 1500 v2: 1,536Wh at $949Inverter: 800W continuous and 1,600W surge against 2,000W and 4,000W
Why it mattersIf you're unsure whether you need 1,536Wh, ask whether anything on your list draws more than 800W.
EcoFlow's figure describes the RIVER working hard, during a fast charge or a heavy loadA2. Jackery's is the quietest the Explorer gets. At a CPAP's draw the real gap is narrower than it looks, and it may even run the other way.
the RIVER 2 Pro is listed at 62dB, EcoFlow's maximum when charging or discharging at high wattageA2the Explorer 1500 v2 is listed at 30dB, Jackery's best caseone RIVER 2 Pro owner cut away internal plastic to fit a quieter fanA1
Why it mattersNeither is proven quieter at a bedside, and one owner still opened the case to swap the RIVER's fanA1. If fan noise worries you, do the heavy charging in another room.
The specific dimensions that decide these two units β everything else is a tie.
Your Life, Your Pick
Selected because: The RIVER 2 Pro finishes one of the six load profiles and the Explorer 1500 v2 finishes three.
The tailgate and the workday are where they split. The RIVER 2 Pro misses the tailgate by 17Wh after our allowance for conversion losses, and the workday by 257Wh. The Explorer finishes both with hundreds of watt-hours left. Neither covers a camping weekend, an eight-hour outage or a van day.
Lifetime Value
Selected because: The Explorer costs more per watt-hour up front and about the same per lifetime kilowatt-hour.
On our numbers the two come out about even per lifetime kilowatt-hour, $0.15 for the Explorer against $0.15 for the RIVER 2 Pro. The Explorer gets there by delivering 6,144kWh across its rated life to the RIVER's 2,304.
That only pays if you use the cycles. A cycle is one full drain and refill, and at one a day the RIVER's rating lasts about 8.2 years to the Explorer's 11.
Portability & Form Factor
Selected because: 17.2 lb against 32 lb is the cheaper unit's strongest line.
weight
17.2 lb is a one-hand grab off a garage shelf. 32 lb is both hands and a moment's thought about whether this trip needs it.
Per watt-hour stored, the Jackery is the lighter design, and reviewers call it the lightest 1.5kWh LFP station on the marketB1. That doesn't help at the tailgate, where you carry the whole box or none of it.
What the Specs Don't Tell You
Selected because: The noise card compares two different kinds of rating, and switchover leans Jackery.
rated cycles
Switchover leans Jackery, rated at 20ms or less to the RIVER's 30ms or less. That's the gap between wall power dropping and the battery taking over, and many desktops won't ride through 30ms. Warranty is a tie at five years, the Jackery's with registration.
Brand Trust
Selected because: Our pick has the weaker app and the smaller owner community.
Our pick has the weaker app. Jackery's rates 2.3 to 3.3 out of 5, it's split across two apps, and it wants a login even when you're offline. EcoFlow's iOS app sits at 4.6.
Neither brand's support has many fans, so I'd buy from a retailer with a real return window. Jackery is on the shelf at Costco, Home Depot and Best Buy. EcoFlow has the bigger owner community, which is where you find an answer late at night.

Conclusion
October 25, 2026
Verdict: the Explorer 1500 v2, on Power Score margin
Buy the Jackery Explorer 1500 v2 unless your list is short. It holds twice the energy and runs 2,000W to the RIVER 2 Pro's 800W, so it finishes three of our six load profiles to the EcoFlow's one. It costs $600 more and charges more per watt-hour of capacity, so the case rests on what it can run. If a CPAP, a phone and a laptop are the whole list, the RIVER 2 Pro covers it at a little over half the weight.
Today the Explorer 1500 v2 is $849, $100 under its typical $949. The verdict weighs typical prices, not today's. Prices checked 28 days ago.

See the full weight table and data sourcing on our methodology page βClass ranking (the star rating)
Each unit's star score is a category ranking, not customer reviews β 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 5β . Here, RIVER 2 Pro rates 4.7/5 (84th percentile of 20 Compact-class units), and Explorer 1500 v2 rates 3.8/5 (31st percentile of 27 Everyday-class units).
How the class ranking is computed βTest Notes & Caveats
Hidden gotchas and advantages we spotted that you won't find on the product page.
62dB is a working-hard number
The RIVER 2 Pro's 62dB is EcoFlow's figure for charging or discharging at high wattage. The Explorer 1500 v2's 30dB is Jackery's best case. The two can't be subtracted. At light loads the RIVER sits well below its rating.
Switchover rated at 20ms against 30ms
Both list a UPS mode, where the battery takes over when wall power drops. The Explorer is rated at 20ms or less and the RIVER 2 Pro at 30ms or less. Many desktop power supplies won't ride through a 30ms gap, so plan on a reboot with the EcoFlow. The fussiest sit right at the 20ms line.
Five years on both
Both carry five years of cover. The Explorer's full term depends on registering it with Jackery.
4,000 cycles only count if you spend them
Cycled daily, the RIVER 2 Pro's rating runs about 8.2 years and the Explorer's about 11. Cycled on weekends, both run for decades.

Reports pinned to the RIVER 2 Pro itself are few, since most threads cover the RIVER 2 line as a wholeA0. The fan comes up most. EcoFlow's spec footnote allows for up to 62dB at high wattageA2, and one owner swapped in a quieter fan, which meant cutting away internal plasticA1.
The rest are open questions. One post asks whether UPS use costs battery lifeA3. The closest thing to a CPAP report is a van-dweller running a ResMed overnight off a DC cableA4, which says more about the cable than the battery.

Who Should Buy Which
Buy the RIVER 2 Pro if youβ¦
- βThe CPAP sleeper with a short list: a night on the machine uses about half of what the RIVER 2 Pro can deliver.
- βAnyone who carries it further than the trunk: 17.2 lb is a one-hand lift.
- βAnyone on a budget: $349, with capacity at a lower cost per watt-hour.
Buy the Explorer 1500 v2 if youβ¦
- βAnyone whose day looks like our workday or tailgate: the Explorer finishes both, and the RIVER 2 Pro finishes neither.
- βAnyone starting a motor or a compressor: 2,000W continuous and a 4,000W surge against 800W and 1,600W.
- βDaily cyclers: 4,000 rated cycles is about 11 years at one a day.
- βSolar users: 400W of panel input to 220W.
If neither fits
A van-life day at 4,685Wh is more than three times what the Explorer can deliver, and even our eight-hour evening outruns it. Look at a larger station.
The Bottom Line
The Explorer 1500 v2 is the one to buy if your list goes past a CPAP night. It finishes the workday and the tailgate that the RIVER 2 Pro can't, and its inverter is rated well past the EcoFlow's.
The RIVER 2 Pro keeps a real claim: $600 less, a little over half the weight, and a CPAP night with half the battery left. If that's your whole list, take it.
Frequently Asked Questions
Answers drawn from the spec record and cited owner research.
Is the Jackery Explorer 1500 v2 worth $600 more than the EcoFlow RIVER 2 Pro?
Yes, if you'll use the capacity or the output. It holds 1,536Wh to 768Wh, runs 2,000W to 800W and takes 400W of solar to 220W. Capacity costs more per watt-hour on the Jackery, so if your whole list fits inside a CPAP night, the RIVER 2 Pro is the better buy.
Can the EcoFlow RIVER 2 Pro run a CPAP all night?
Comfortably. An overnight CPAP profile is 320Wh, about half of what the RIVER 2 Pro can deliver, so it finishes with 333Wh left. The Explorer 1500 v2 finishes the same night with 986Wh left.
Which one is quieter?
The ratings can't settle it. The RIVER 2 Pro is listed at 62dB, EcoFlow's maximum when charging or discharging at high wattage. The Explorer 1500 v2 is listed at 30dB, Jackery's best case. At a light load the RIVER 2 Pro runs well below its rating.
Will either one get me through an 8-hour blackout?
Not the whole way. That profile is 1,645Wh. The Explorer 1500 v2 covers about 79% of it and the RIVER 2 Pro about 40%. Both can start the loads, so the limit is capacity rather than the inverter.
Can you add batteries to either one later?
No. Both are fixed, 768Wh on the RIVER 2 Pro and 1,536Wh on the Explorer 1500 v2, with no expansion battery for either. Buy the capacity you need on day one.
