Exactly the same battery size. One has more power and solar; the other more outlets and less weight.
The BLUETTI AC70 and the EcoFlow RIVER 2 Pro both store 768Wh of LFP rated for 3,000 cycles. The AC70 delivers 1,000W from two AC outlets, takes 500W of solar and switches to battery in 20ms or less, at 22.5 lb. The RIVER 2 Pro delivers 800W from four outlets, adds two DC barrels, takes 220W of solar and switches in under 30ms, at 18.2 lb. On October 30, 2026, BLUETTI US listed the AC70 as sold out.
Below: every difference with numbers, a 20-second calculator for your own gear, seven modeled situations, a third option, and what published tests found on each.
Same 768Wh, prices $10 apart today. The AC70 has 200W more output, more than twice the solar input and a faster switchover; the RIVER 2 Pro has twice the AC outlets, DC barrels and weighs 4.3 lb less, and it was the one in stock on October 30, 2026.

The five differences that decide it
The five gaps that decide the purchase, with the better spec for most buyers flagged. Both store 768Wh of LFP rated for 3,000 cycles to 80%, have a 12V car socket, take no extra battery and carry a 5-year warranty from their US store.
Will it run your setup? Check in 20 seconds
Estimates use 85% usable capacity and 70% of rated solar output. Real results vary with temperature, inverter load, shade and appliance cycling. Fridge and freezer watts are daily averages and do not include compressor startup surges.
Runtime by appliance, one at a time
Simple energy estimates, not measured runtimes. About 653Wh usable on both; APH Networks got 731Wh out of an AC70 at 136W, and OutdoorGearLab measured 600Wh out of the RIVER 2 Pro.
Same battery, same runtime.
The AC70 and the RIVER 2 Pro both hold about 653Wh usable, so every appliance runs just as long on either one.Get our Black Friday alerts for power stations

The price gap, in numbers
Same 768Wh battery: the BLUETTI AC70 costs $10 less than the EcoFlow RIVER 2 Pro.
Prices refresh daily from BLUETTI US and EcoFlow US.Same capacity and the same 3,000-cycle rating to 80%, so the price gap is the whole money story. If the AC70 is sold out when you check, only the RIVER 2 Pro price applies. Both prices move often; the figures are refreshed daily by our price engine.
The third option: the BLUETTI Elite 100 V2 at $499
BLUETTI Elite 100 V2: $499 today
A step up from both: 1,024Wh, 1,800W from four outlets, 1,000W of solar, a 10ms UPS and two DC barrels, at 25.3 lb, and rated for 4,000 cycles. Pick it if 768Wh or 1,000W feels tight. Our Elite 100 V2 review goes deeper. See the Elite 100 V2 at BLUETTI.
Seven modeled situations, worked out
Same formula as the calculator above. Both carry 768Wh, so runtimes match; the differences show up in what each can power and how it refills.
24-hour outage, essentials only
Identical: an evening. Neither covers a full day with a fridge.
CPAP, two nights
Both cover two nights with almost nothing to spare. OutdoorGearLab found the RIVER 2 Pro’s fan high-pitched and unpredictable beside a CPAP at night.
A 900W microwave
Only the AC70 runs it. X-Boost on the RIVER 2 Pro is for heating loads, not microwaves.
Four plugs at once
The RIVER 2 Pro takes all four plugs; the AC70 needs a power strip, keeping the total under 1,000W.
Refill from solar, each at its maximum
The AC70 refills in a morning; the RIVER 2 Pro needs a full sunny day.
Refill from the wall before a storm
Both are quick. Trusted Reviews measured 86 minutes to full in Turbo on a UK AC70; OutdoorGearLab measured 75 minutes on the RIVER 2 Pro.
Carrying it to a campsite
Both are one-hand carries; the RIVER 2 Pro is 4.3 lb lighter.

09 · NoiseNoise: AC70 vs RIVER 2 Pro
The BLUETTI AC70 is the quieter one: Ken Rockwell measured its fan at 35 to 40dBA at 1 m while charging, and APH Networks found it quiet in every test. EcoFlow rates the EcoFlow RIVER 2 Pro at up to 62dB at high charge or discharge, and OutdoorGearLab found its fan high-pitched and unpredictable.
The RIVER 2 Pro figure is EcoFlow’s own worst case. The AC70 figures are one reviewer’s measurements.Every figure we found, with its source
What reviewers heard: Fan stayed quiet in every test (APH Networks); a brief high-pitched noise when the AC ports turned on, and on mains with loads under about 100W (Trusted Reviews, UK unit).
What reviewers heard: High-pitched, unpredictable fan during charging and heavy draw, a problem at a desk or beside a CPAP at night (OutdoorGearLab).
Measured by a tester Brand figure
- Use the slower charging mode overnight.
Cold and heat: AC70 vs RIVER 2 Pro
For a cold garage, the BLUETTI AC70 keeps running down to −4°F; for heat, the EcoFlow RIVER 2 Pro is rated to 113°F. Neither charges below freezing.
Figures from the AC70 US manual and the EcoFlow US RIVER 2 Pro page.- Charge either one indoors in winter: neither charges below 32°F.
- In a hot car, the RIVER 2 Pro has more margin: rated to 113°F, against 104°F for the AC70.
App, UPS and smart features
The BLUETTI AC70 has the faster UPS, 20ms or less against under 30ms, and Power Lifting to 2,000W. The EcoFlow RIVER 2 Pro adds Wi-Fi, so you can check it away from home.
Neither takes an extra battery. The gap is UPS speed and Wi-Fi.Green zone: a switch under about 16ms, which most desktop PCs ride through without restarting.
Can you check it away from home? The BLUETTI AC70 connects over Bluetooth only, and APH Networks noted any phone with the BLUETTI app can connect to it without a confirmation. The EcoFlow RIVER 2 Pro adds Wi-Fi.
Does it have a fast charging mode? The BLUETTI AC70’s Turbo Charging, enabled in the app, reaches 80% in 45 minutes. EcoFlow lists no separate fast mode for the RIVER 2 Pro, which charges at up to 940W, full in 70 minutes.
Does it work as a UPS? APH Networks and Trusted Reviews kept a PC running through the BLUETTI AC70’s switchover, rated at 20ms or less. The EcoFlow RIVER 2 Pro’s EPS is under 30ms, fine for appliances and borderline for desktop PCs.
Can it run a heater or kettle above its rating? Both run heaters past their rating at reduced power: Power Lifting to 2,000W on the BLUETTI AC70, X-Boost to 1,600W on the EcoFlow RIVER 2 Pro. Neither helps motors.
Can you add a battery later? Neither takes an extra battery. A B80, B230 or B300 can recharge the BLUETTI AC70 through its DC input in Power Bank Mode.
Warranty and support
EcoFlow US gives the EcoFlow RIVER 2 Pro 5 years with no registration condition. The BLUETTI AC70 gets 5 years when bought from BLUETTI’s official store; bought elsewhere, its US manual says 24 months, extended for free with BLUETTI VIP registration.
BLUETTI’s warranty table says 5 years; its manual says 24 months outside its own store. We show the shorter base.Subject to each brand’s warranty terms and eligibility.
Both are rated for 3,000 cycles to 80% capacity, about 8 years at one full cycle a day.
- Buy the AC70 from BLUETTI for the full 5 years, or register it with BLUETTI VIP on the official site if you buy it elsewhere. Keep proof of purchase.
- The RIVER 2 Pro needs no registration to get its 5 years.
What reviewers report
We have not lab-tested these two units. Here is what 8 published reviews found, with the source, author and date for each point. Reviews of UK and EU units are flagged: those models charge from 230V outlets and have different sockets, so their charge times and outlet findings don’t carry over to US units.
