EcoFlow River 2 vs. Bluetti EB3A: The Full Comparison
Now it’s time to take a close look at the EcoFlow River 2 specs against the Bluetti EB3A specs. Let’s see how this tight battle plays out in the trenches. Is the Bluetti really that much better?

Battery Battle
The battery is what stores the energy for later use. It’s usually the most important feature of any small solar generator. The larger the battery, the longer it can power your devices.
The batteries of these two portable power stations are nearly identical. The EcoFlow River 2 battery is rated 256Wh while the Bluetti EB3A battery is 268.8Wh. There’s no doubt the Bluetti is larger. However, this ~13Wh difference is less than one phone charge. Will you notice this difference in daily use? Very unlikely. Other factors are much more noticeable.
This amount of battery power can run essential devices like smartphones, tablets, and small appliances effectively. It is suitable for day trips, camping adventures, or as a backup during power outages. It will struggle with any fridge, powerful desktop computers, and televisions – only providing ~1 hour of power.
For example, these can both:
- Charge a phone >20 times
- Run an LED light for >20 hours
- Power a 200W television for less than 1.5 hours
As you can see, it’s fine for small devices like phones and lights, but not so great when put up against a 200W device like a TV. If you want much more serious home power, go for the EcoFlow Delta Pro Ultra.
Both of these solar generators feature lithium iron phosphate (LFP or LiFePO4) batteries. This is the ideal battery chemistry, offering a long lifespan, ultimate safety, and consistent performance. Learn more about the best off-grid battery chemistry.
EcoFlow states that the River 2 battery can sustain up to 3,000 cycles at 80% of its original capacity. Bluetti drops that down to 2,500 cycles. Battery longevity goes to EcoFlow.
These portable batteries are ideal for lightweight, portable energy solutions. Whether you’re powering lights at a campsite with the EcoFlow River 2 or charging multiple devices with the Bluetti EB3A, these power stations deliver power when you need it most.
If you want a 300W power station with a little more battery, consider the Anker 522 PowerHouse 299Wh Portable Power Station. See all Anker options here.
Verdict: This is a tie. While the Bluetti is slightly larger by 13Wh, it also boasts a shorter lifespan with 2,500 cycles compared to EcoFlow’s 3,000 cycles.
| Feature | EcoFlow River 2 | Bluetti EB3A |
| Battery Capacity | 256Wh | 268.8Wh |
| Extra Batteries (external) | None | None |
| Battery Chemistry | LFP (LiFePO4) | LFP (LiFePO4) |
| Battery Cycles with 80% | 3,000 | 2,500 |

Inverter Information
Batteries and solar panels use direct current (DC) electricity. But household outlets run on alternating current (AC) electricity. To get from the battery’s DC energy to the AC power you find at home, the AC inverter steps in. This rating shows the maximum amount of power the inverter can supply at one time, rated in watts.
But here’s the thing. Many small devices – including anything with a USB charger – uses DC energy. DC also comes out of the DC5221 outlets (small barrel plugs) on both of these power stations. So you don’t need the inverter to charge your phone, power a small light, or use just about any portable device. These two small power stations will do much better with DC devices because they’re usually low power.
Therefore, this category has a questionable amount of importance in the comparison of the EcoFlow River 2 vs. Bluetti EB3A. Don’t buy based on the inverter unless you are certain that you need it.
The Bluetti comes out far ahead in this category, boasting a 600W inverter with a 1,200W peak output. EcoFlow is half that with a 300W inverter and 600W peak. They both are pure sine wave inverters, meaning they provide clean power that is suitable for sensitive electronics.
This does not mean that the Bluetti will last longer. It’s the opposite. If you plug in a 600W device into the Bluetti inverter, you’ll drain the battery entirely in less than 30 minutes. Even if you just use the EcoFlow’s 300W, it will still last less than one hour.
So it’s useless for running a 400-500W fridge because you need that for many hours. But it might help if you have a small blender that can’t use DC power and you only run it for a couple of minutes.
Also, surge or peak power is a rating that can last for short bursts or is done by lowering voltage (or both). It’s better to buy a power station with a continuous rating that matches your device. You can find out more by reading this full article on How Inverters Work.
Verdict: The Bluetti’s 600W inverter is better than EcoFlow’s 300W. But both units excel by using the DC ports and avoiding the AC inverter entirely.
| Feature | EcoFlow River 2 | Bluetti EB3A |
| AC Output | 300W Pure Sine Wave | 600W Pure Sine Wave |
| AC Peak Output | 600W (X-Boost) | 1,200W |

Charging Rates
Since these devices have relatively small batteries, charging rates could be a very important feature to consider. This includes AC charging rates from a regular home outlet and DC charging rates for solar panels and 12V car outlets.
The maximum charging rates of the EcoFlow River 2 vs Bluetti EB3A are nearly identical, at 360W for the EcoFlow and 350W for the Bluetti. This can get you to 80% in less than 30 minutes, and a full charge in just about an hour.
In comparison to the Jackery Explorer 300 Plus Power Station with a 120W AC input, both of these are much faster. Read more about Jackery’s full lineup here.
When it comes to solar power, Bluetti EB3A holds a major advantage. And this could be the dealbreaker for many people:
- The EcoFlow River 2 solar input is 110W, full charge in less than 3 hours under ideal conditions
- Bluetti EB3A solar input is 200W, full charge in less than 2 hours under ideal conditions
The EcoFlow solar charging rate of 110W is sufficient considering the battery size. But Bluetti solar charging is faster.
Both of these portable power stations offer other charging inputs from 12V car outlets and fuel generators (using the AC input).
It’s worth mentioning that Bluetti says the EB3A has a UPS function (uninterruptible power supply). But it’s not a true UPS that can work for delicate computers. It still has a 20 ms delay. So even though EcoFlow says it’s an EPS and Bluetti says UPS, they both offer similar functions. You can use it as a backup power device, but if an outage occurs, your computer/server might reboot. Bluetti comes out marginally ahead with a 20 ms switchover compared to EcoFlow’s 30 ms.
Verdict: Bluetti comes out ahead with a 200W solar input, but both devices have impressively fast recharge rates for both AC and solar inputs. They come with nearly identical EPS/UPS support of 30 ms or less switchover.
| Feature | EcoFlow River 2 | Bluetti EB3A |
| AC Charging Rate | 360W | 268W with 350W Turbo |
| Pass-Through AC Charging | Yes | Yes |
| EPS/UPS Function | Yes, 30 ms | Yes, 20 ms |
| Solar Charging Rate | 110W | 200W (12-28V, 8.5A) |

Other Features: Ports, Apps, Pads, and Warranty
We’ve now covered the big three: battery, inverter, and charging rates. Bluetti outpaces EcoFlow in all three categories, although it’s a marginal amount in each area.
Now it’s time to check out some small items that make a big difference.
The USB ports are identical in the battle between the EcoFlow River 2 and Bluetti EB3A, with two USB-A and one USB-C. They both also have an App to connect to over WiFi or Bluetooth, so you can control them from your phone whether you’re across the room or in a different country.
The Bluetti EB3A jumps ahead with a wireless charging pad on top. For those who love to set their phone down on the charger without the hassle of a cable, there’s no choice but the Bluetti.
However, EcoFlow hits back hard with a 5-year warranty. This is three years of extra coverage compared to Bluetti’s 2-year warranty. When you include the EcoFlow battery cycle rating at 3,000 with Bluetti’s at 2,500, plus this extended warranty coverage, the EcoFlow device beats the Bluetti in longevity.
EcoFlow is also slightly lighter, by about 2.5 lbs (1.1 kg). But Bluetti still only weighs 10.1 lbs (4.6kg). Both are ultra-portable and lightweight power stations.
Verdict: The category is a tie, with Bluetti coming out ahead with its wireless charging pad but EcoFlow hitting back with three additional years of warranty coverage.
| Feature | EcoFlow River 2 | Bluetti EB3A |
| AC Outlets | 2 | 2 |
| USB Ports | 2 x USB-A, 1 x USB-C | 2 x USB-A, 1 x USB-C |
| Wireless Charging Pad | No | Yes |
| App Connection | Yes, WiFi and Bluetooth | Yes, WiFi and Bluetooth |
| Warranty | 5-year | 2-year |
| Weight | 7.7 lbs / 3.5 kg | 10.14 lbs / 4.6 kg |
| Dimensions | 9.6 x 8.5 x 5.7 in 244 x 216 x 145 mm | 10 x 7.1 x 7.2 in 255 x 180 x 183 mm |

Final Verdict
The choice between the EcoFlow River 2 and Bluetti EB3A is a tight one.
Bluetti comes out ahead with a higher inverter rating (600W), faster solar panel charging (200W), and a wireless charging pad.
But EcoFlow’s battery is rated for more cycles (3,000) and it has a longer warranty (5 years). And even though they’re smaller than Bluetti EB3A’s, the EcoFlow River 2 inverter and solar input are both appropriately sized for this device with a 258Wh battery. There’s really no need to go as high as Bluetti. You’ll find devices that don’t offer this balance, but this comparison just shows why EcoFlow vs. Bluetti is the battle of the industry titans. They’re both excellent power station manufacturers that know how to design them right.
What does the choice come down to? If you need an inverter over 300W, want to use a 200W solar panel, or have a wireless charging pad, the Bluetti EB3A is the best solar generator for your needs. If you want a longer warranty and are fine with a 300W inverter and 110W solar panel, the EcoFlow River 2 is still a great choice.
