At a glance
Two ~700Wh LiFePO4 stations, two different bets: the EB70S spreads its budget across ports and a flat-top work surface, while the RIVER 2 Pro spends it on a bigger inverter and app control. Here is how the trade-offs land for camping, CPAP, and short outages.
- EB70S: more ports, flat top, 800W continuous — the utility player.
- RIVER 2 Pro: 1600W continuous per the listing, app control, lighter — the power-density play.
- Both: LiFePO4, ~20 lb, AC recharge in a few hours, no 240V output.

If you are shopping the ~700Wh class, these two are the obvious pair to put side by side. The BLUETTI EB70S and the EcoFlow RIVER 2 Pro both use LiFePO4 cells, both weigh around 20 lb, and both are aimed at campers, CPAP users, and short-outage backup. The difference is where each one spends its budget.
The EB70S bets on port variety and a flat-top work surface: four AC outlets, two USB-C, two USB-A, a car socket, and two DC ports, plus a fold-down handle that leaves the top clear for stacking gear or a wireless charging pad. The RIVER 2 Pro bets on a bigger inverter and app control: 1600W of AC output per the listing, a single 100W USB-C port, and a phone app that lets you watch input/output and dial charge rates.
On price, the RIVER 2 Pro is listed at $439. The EB70S price is not on file, so this is not a same-money comparison — check the current EB70S price before you decide, because the value case shifts with the gap between them.
This is not a page for whole-home backup or running a 240V well pump. Both are mid-size stations for tailgating, tent camping, CPAP overnight, and keeping the fridge and router alive through a few hours of outage. If you need to run a furnace blower or a 30A transfer switch, neither of these is the right tool.
- EB70S: more ports, flat top, 800W continuous — the utility player.
- RIVER 2 Pro: 1600W continuous per the listing, app control, lighter — the power-density play.
- Both: LiFePO4, ~20 lb, AC recharge in a few hours, no 240V output.

Spec snapshot
Numbers below come from the WattPicks catalogue and the listings on file. Where a figure is not published, the cell says n/a (not on file) rather than guessing. The RIVER 2 Pro capacity is listed as 768Wh in the product name; the catalogue capacity field is not on file, so treat that number as listing-sourced. The RIVER 2 Pro output is 1600W per the listing; the product name includes '800W', which we treat as a model-name artifact, not the continuous rating.
Ratings are listing aggregates, not owner proof — useful for a rough sense of volume, not a substitute for reading the trade-offs below.
| Product | Price | Capacity (Wh) | Output (W) | Weight (lb) | Rating |
|---|---|---|---|---|---|
| BLUETTI EB70S | n/a (not on file) | 716 Wh | 800 W | 21.4 lb | 4.4 |
| EcoFlow Portable Power Station RIVER 2 Pro, 768Wh 800W | $439 | 768 Wh (listing) | 1600 W (listing) | 18.2 lb | 4.5 |
Where the money went
Four configuration choices separate these two more than the headline wattage does.
Ports. The EB70S gives you four AC outlets and two USB-C ports, one of which is 100W PD. The RIVER 2 Pro lists a single USB-C port; its AC outlet count is not on file, so check the listing before you buy if outlet count matters. If you routinely charge two USB-C laptops or a laptop plus a tablet, the EB70S is the easier fit. If you mostly run AC appliances and one USB-C device, the RIVER 2 Pro's port count is not a problem.
Inverter headroom. The EB70S is rated 800W continuous. The RIVER 2 Pro is rated 1600W continuous per the listing — double the AC ceiling. That matters for resistive loads like a coffee maker or a space heater, and for motor starts on a fridge or sump pump. Owner notes on file report the RIVER 2 Pro running an 800W coffee maker and a 1/3 HP sump pump with roughly 1600W surge; EB70S owners report a freezer with about 1000W startup peak. Neither is a whole-home solution, but the RIVER 2 Pro has more room before it trips.
Recharge speed. The EB70S recharges from AC in about 3.5 hours at roughly 193W regulated input, and from a 180W solar panel in about 4 hours in full sun. The RIVER 2 Pro recharges from AC in about 70 minutes per the listing, and owner notes on file report 28% to full in under an hour. If you are topping up between errands or during a short outage window, the RIVER 2 Pro is meaningfully faster.
Control and monitoring. The RIVER 2 Pro has an app for state of charge, input/output, and charge-rate limits. The EB70S relies on a small LCD that sleeps quickly — a few seconds in ECO mode, about 10 seconds otherwise — and tiny indicator LEDs that are hard to see in daylight. Owner notes on file mention the display and indicator quirks on both sides; the RIVER 2 Pro's app is the cleaner workaround.
- EB70S: 4 AC, 2 USB-C (one 100W), 2 USB-A, car, 2 DC — more simultaneous charging.
- RIVER 2 Pro: 1 USB-C; AC outlet count not on file — check the listing.
- EB70S: ~3.5 hr AC recharge; RIVER 2 Pro: ~70 min AC recharge per listing.
- RIVER 2 Pro: app control; EB70S: LCD with short timeout and dim LEDs.
The spec that decides it
For most buyers, the deciding number is continuous AC output, not capacity. The EB70S at 800W will run a fridge, a CPAP, lights, and a fan, but it will not comfortably run a 1500W space heater or a full-size coffee maker. The RIVER 2 Pro at 1600W per the listing opens up those resistive loads, and owner notes on file report it running an 800W coffee maker and a 711W toaster.
The second deciding factor is recharge speed. If your use case is a weekend camping trip where the station sits on a solar panel all day, the EB70S's ~4-hour solar recharge is fine. If your use case is a short outage where you can only recharge between grid cycles, the RIVER 2 Pro's ~70-minute AC recharge can be the difference between usable and not.
- Buy the EB70S if your loads stay under 800W and you want more USB-C and DC ports.
- Buy the RIVER 2 Pro if you need to run a coffee maker, heater, or sump pump, or if fast AC recharge matters.
Real owner trade-offs
The owner notes on file line up with the spec sheet, with a few caveats worth knowing before you buy. These are owner themes, not lab bench results.
EB70S owners praise the port layout and the LiFePO4 cycle life, and several mention running a 12V cooler overnight or a 150W aquarium setup for about 18 hours. The recurring complaints are the loud AC adapter fan, the dim indicator lights that make it easy to leave a section on and drain the battery, and the LCD that sleeps within seconds. A few owners report units that stopped accepting solar or AC charge, with support experiences ranging from helpful to unresponsive.
RIVER 2 Pro owners highlight the fast AC recharge, the app, and the lighter weight — 18.2 lb versus 21.4 lb for the EB70S. Owner notes on file report a 50-inch TV running about 9 hours and a 12V car fridge for 36 hours before hitting 10%. The caveats: only one USB-C port, no simultaneous charging from multiple sources (AC, DC, or USB-C, one at a time), and mixed customer support reports. A few units have had charging-limit or shutdown problems, some resolved with support.
- EB70S: loud charger fan, dim LEDs, short display timeout; support inconsistent.
- RIVER 2 Pro: one USB-C, no simultaneous charging; support inconsistent.
- Both: LiFePO4, ~20 lb, no 240V output.
Buy the one that…
Buy the BLUETTI EB70S if your loads stay under 800W and you want the most ports per dollar — two USB-C, two USB-A, four AC, a car socket, and two DC ports — plus a flat top for stacking gear. Skip it if you need to run a coffee maker, space heater, or sump pump, or if fan noise in a quiet room would bother you.
Buy the EcoFlow RIVER 2 Pro if you need 1600W of AC headroom per the listing, fast ~70-minute AC recharge, app control, and a lighter carry at 18.2 lb. Skip it if you need two USB-C ports, simultaneous charging from multiple sources, or if you are not willing to test the unit thoroughly during the return window given the mixed support reports.
- EB70S: buy for port variety and flat-top utility; skip for high-wattage appliances.
- RIVER 2 Pro: buy for inverter headroom and fast recharge; skip for dual USB-C or multi-source charging.
Frequently asked
How do I estimate CPAP watt draw for these stations?
Check your CPAP's power supply label for watts (or volts × amps). A typical CPAP with humidifier runs 30–60W; without humidifier, often 10–20W. Multiply by hours of sleep to get Wh per night, then compare to 716Wh (EB70S) or 768Wh (RIVER 2 Pro), leaving a 20% buffer.
Why does the RIVER 2 Pro name say 800W if the listing says 1600W?
The product name includes '800W', but the listing's continuous AC output is 1600W. We treat the name as a model-name artifact and use the listing figure, labeled as listing-sourced, throughout this page.
How can I test the EB70S or RIVER 2 Pro during the return window?
Run your heaviest planned load for at least 10 minutes and confirm the station does not trip; check that AC, solar, and car charging each work; verify the display or app shows input and output correctly; and note any fan noise or indicator-light issues that would bother you long-term. For a scenario-specific check, run your CPAP plus fridge surge on the EB70S for 10 minutes.
Can the EB70S run a CPAP overnight?
Owner notes on file report using it for CPAP and phone charging overnight with charge remaining; the 716Wh capacity and 800W output are enough for a typical CPAP setup, but check your machine's watt draw.
Can the RIVER 2 Pro run a fridge?
Owner notes on file report running an apartment-size fridge with a ~768W surge and 115–135W running draw; a full-size fridge with a 2000W+ surge is outside its 1600W continuous rating.
Which recharges faster from solar?
The EB70S recharges from a 180W panel in about 4 hours in full sun; the RIVER 2 Pro recharges in about 3.5 hours with 220W solar input per the listing. Panel wattage and sun conditions matter more than the station.
Do either support simultaneous charging from AC and solar?
The RIVER 2 Pro does not support simultaneous charging from multiple sources — AC, DC, or USB-C, one at a time. The EB70S listing does not specify multi-source charging; owner notes on file report using it while charging from a single source.
