EcoFlow River 2 vs Bluetti EB3A

Recharge times

Both power stations have multiple charging options – AC, DC, and solar input. The River 2 charges faster when using the AC option, taking only 1 hour from 0-100%. When you do outdoors, the tables turn, and you can save up to 1 hour with the EB3A.

  Bluetti EB3A EcoFlow River 2
AC Adapter 1.3-1.8 hrs (350W) / 1.5-2.0 hrs (268W) 1 hrs (360W)
Car adapter 3.2-3.7 hrs (12V, 100W) / 1.9-2.4 hrs (24V, 200W) 3.2-3.7 hrs (12V, 100W)
Solar Recharge 1.8-2.0 hrs (200W) 3.0 hrs (110W)

Verdict

If portability is your main concern, then the EcoFlow River 2 should be at the top of your list. However, if you need a bit more power, then the EB3A’s extra capacity and output might work better for you.

Overall, both models are excellent products and offer great value for money. Just make sure to weigh your needs carefully before choosing.

First impressions

Both units look sleek and modern, with a sturdy build that makes them perfect for outdoor use. This time, I liked the design of the Bluetti more due to the placement of the ports.

For the Bluetti, all the ports are located at the front of the device, but with the River Pro, they are divided between the front and sides. For most users, however, this should not be a problem.

Looking closer at the features, here’s what the units have to offer:

  Bluetti EB55 Ecoflow River Pro

Portability

As far as weight is concerned, these two battery stations are almost the same. The River Pro weighs slightly more at 16.8 lbs, while the EB55 comes in at 16.5 lbs.

When it comes to portability, the EB55 has a slight advantage. It’s a tad slimmer, but the difference is not something you’d usually notice.

Ports

The EB55 has a total of 15 ports, consisting of 12 output ports and 3 input ports. As such, you can charge up to 12 devices at a time with this power station.

With a total of 13 ports, on the other hand, the River Pro offers slightly less versatility. It has 10 output ports and 3 input ports which allow you to charge up to 10 devices at once.

EcoFLow River Pro vs. Bluetti EB55

This makes the EB55 the better choice if you need to charge multiple devices simultaneously.

Battery capacity, and power

Even though the difference in size and weight is quite negligible, there is a notable difference when it comes to the capacity. The River Pro has a higher capacity of 720Wh, while the EB55 works with 537Wh.

In terms of power, the Bluetti EB55 surprisingly has more to offer, with a continuous output of 700W compared to the River Pro’s 600W.

EcoFLow River Pro vs Bluetti EB55 Comparison

Recharge times

The EB55 takes almost an hour longer to charge fully when using the AC outlet, taking 3.0 hours in total compared to the River Pro’s 1.6 hours. On the other hand, it takes slightly lesser time to recharge using a car or solar charger.

  Bluetti EB55 Ecoflow River Pro
AC Adapter 3.0 hrs (200W) 1.6 hrs
Car adapter 6.1 hrs (12V, 100W) / 3.4 hrs (24V, 200W) 6.55 hrs (12V)
Solar Recharge 3.0 hrs (200W) 4-9 hrs (2 x 110W solar panels) / 6-12 hrs (1 x 160W Solar Panel)

Verdict

The River Pro and EB55 are both great budget-friendly power stations. The River Pro has more capacity, while the EB55 offers more power. It all depends on which of these features is most important for your needs.

I think that the most important factor here is that the River Pro is Lithium-ion based, while the EB55 uses Lithium-ion Phosphate battery cells. This could make a real difference in terms of durability and long-term performance, so bear it in mind when making your decision.


 

3. Mid range (around $1000) – Ecoflow Delta 2 vs. Bluetti EB150

Warning: Bluetti EB150 is a very old model and has been discontinued on their official site. It is available on Amazon though. I highly suggest you avoid this model if you can

EcoFlow Delta 2 vs Bluetti EB150 Power Station

EcoFlow Delta 2 and Bluetti EB150 meet the sweet spot of 1000W. Hence this is one of the most sought-after categories in power stations.​

First Impression

EC Delta2 is more aesthetic than EB150. The nice color combination makes it awesome looking. Also, the body is designed so well to make it look like a futuristic gadget. In terms of look, EcoFlow Delta is better, hands down.

Looking closer at the features, here’s what the units have to offer:

User manual EB150 Delta 2

Portability

As far as weight is concerned, one is heavier than the other. The Delta 2 weighs less at 27 lbs, while the EB150 comes in at 37.9 lbs.

When it comes to portability, the Delta 2 has an advantage. But, Bluetti is slimmer and can fit in easily in small places.

Ports

EcoFlow Delta 2 vs Bluetti EB150

The number of ports and the power ratings is compared in the following table.

EcoFlow Delta 2 Bluetti EB150

AC Charging Port 1200W (100-120V~ 50Hz/60Hz) 200 W 220V 50Hz
Car Charging Port 12V/24V, 8A

As we can see, Bluetti EB150 misses out on a lot of ports both input and output ports.

Battery capacity, and power

In terms of capacity, EcoFlow Delta 2 outperforms Bluetti EB150 both in Power and Surge capacity. But in the battery capacity, Bluetti is way above Ecoflow. If you ask me, both power and battery capacity are good to consider. The more power you have, the more devices can be powered simultaneously. For example, you can drive a TV (150W), an Oven (900W), and a refrigerator (600W) simultaneously using a 1800W power station. With a 1000W station, you can only power an Oven or TV + Fridge, not all of them together.

On the other hand, a high battery capacity helps you run devices for a longer period of time. For example, you can run your oven for 1.8 hours with Bluetti while it’s only 1.2 hours with Delta 2.

There is a clear trade-off, if you need one, you may have to miss the other.

Also, EcoFlow Delta 2 has higher LifeCycle due to the use of LFP battery.

  Bluetti EB150 Ecoflow Delta 2
Battery Capacity 1500Wh 1024Wh
Continuous Power 1000W 1800W
Surge Power 1000W 2700W
Expandable Battery No Yes (Upto 3kWh)
Lifecycle 2,500 cycles to 80% original capacity 3000+ cycles to 80% capacity (LFP Battery)

Recharge times

Both the power station support more than one way to charge them. The following table highlights the difference.

EcoFlow Delta 2 Bluetti EB150
AC Wall Outlet ~1.6 Hours for a full charge ~10 Hours for a full charge
Solar Panel Supports 500W Panel Supports 400W Panel
Car Yes (~13.5 Hours) No
Solar Bundles Yes (2 options, view here) No

The charge time of EcoFlow Delta 2 is significantly lesser than that of Bluetti EB150. Also, having the option to charge via your car is a good thing to have. EcoFlow Delta 2 has the option for you while Bluetti EB150 missed it.

Verdict

The Delta 2 and EB150 are both great 1000W category power stations. Delta 2 is newly released and hence packs all the latest technology. EB150 is an older model and hence lacks some of the significant features. The only reason to pick Bluetti EB150 would be for that big battery capacity. In all other aspects, Delta 2 is the clear winner.


 

4. High range (around $2000) – Ecoflow Delta Max (2000) vs. Bluetti AC200Max

These two power stations from EcoFlow and Bluetti are some of the most powerful units in their respective lineups. Both offer plenty of power for most of your energy needs and are great investments for those who need something a bit more powerful than the others on this list.

Solar Input 3.0-3.5 hrs (900W) 3.2-6.3 hrs (800W)

Which one is the better pick?

Both the Delta Max (2000) and AC200Max provide a great balance of portability, capacity, power, and recharge times. The Delta Max (2000) is a great option for those who prioritize quick AC recharge times, but then again, you’ve got to consider that it’s Li-ion based.

In general, LiFePO4 batteries are more reliable and durable, so the Bluetti AC200Max is a better choice if that’s your main concern.


 

5. Top Range (around $3000) – Ecoflow Delta Pro vs. Bluetti AC300 + B300

EcoFlow Delta Pro vs. Bluetti AC300+B300

Recharge Time

The EcoFlow Delta pro will charge faster out of the box, taking about 2.7 hours using a regular 1800W output. Increase the wattage to 3000W and you can get a full charge in 1.8 hours.

The AC300 + B300 takes about 6.5-7 hrs with a 500W input, but if you opt for the 30A AC charging cable that supports 3000W, you can reduce the charging time to 1.5 hours.

  Bluetti AC300 + B300 EcoFlow Delta Pro
AC Input 6.5-7hrs (500W) / Approx 1.5 hrs (3000W) 2.7 hrs (1800W) / 1.9hrs (2900W) / 1.8hrs (3000W)
Solar Input 15.5-16hrs (200W) 2.8-5.6 hours (1600W)
EV Charging No EV charging option 1.7 hours (3400W)

You will need an EV charging adapter sold separately.

Car Input 30hrs (100W) / 15hrs (200W) Approx 21 hours

So, which is the better pick?

I would pick the EcoFlow Delta Pro simply because it offers more power, a higher capacity, and faster recharge times out of the box. And that’s not all. It’s more compact as a single unit, and the wheels make it easier to move around.

Don’t get me wrong. The AC300 + B300 is also a great choice as well and might be better for those looking for more port options. Since it also comes as two smaller units, it can be a good option if you want something more modular.
