Quick Rundown

Both EcoFlow and Bluetti have extensive lines of power stations. But the battle of the  EcoFlow Delta 2 vs. Bluetti AC200P has a clear winner. 

The Bluetti AC200P and the very similar Bluetti AC200MAX are superior in many ways, including:

• Larger 2,000Wh internal battery (about double the EcoFlow) with much more expansion potential
• Slightly more powerful AC inverter and solar input
• Wireless charging pad and high-amp DC Anderson output (AC200MAX has 30-amp AC outlet too)

The EcoFlow Delta 2 hits back with a few highlights of its own. The biggest advantage is that it’s much lighter, which is a result of the battery being about half the size. The EcoFlow Delta 2 also has:

• An extra year of warranty coverage (5 years)
• An extra USB-C port with 100W
• 30ms emergency power supply function

To be frank, the EcoFlow’s battery being half the size is a glaring problem that is hard to overcome. The Bluetti can power your devices for twice as long. 

With double the battery capacity and impressive features, the Bluetti AC200P is the clear winner.

But that’s not the end of the story.

The AC200P is an older model that may be hard to find in stock. But have no fear. The Bluetti AC200MAX is a very similar replacement that’s also usually priced around the same level. And it matches EcoFlow’s 5 year warranty and 100W USB-C port. It even throws in the ability to control and monitor it from the Bluetti app, and a 30-amp AC outlet for connecting to an RV or other high-draw devices.

On the other side of the coin, EcoFlow also has an alternative that’s more comparable to both of these Bluetti models. It’s the EcoFlow Delta 2 Max. The problem? It’s often hundreds of dollars more expensive.

At the end of the day, this is a messy battle but the Bluetti AC200P is ideal. And if you can’t find that in stock, the Bluetti AC200MAX is a great alternative. The EcoFlow Delta 2’s smaller battery just doesn’t hang with this group, and while the EcoFlow Delta 2 Max has what it takes, the price tag is a tough pill to swallow.

There are many details not covered in this summary. So let’s jump into those now. 

We’ll focus on the EcoFlow Delta 2 vs. Bluetti AC200P. But we’ll also throw in the details for the closest alternatives. Pay close attention to the Bluetti AC200MAX because it’s the one we recommend the most if you are looking at these two.

EcoFlow Delta 2 vs. Bluetti AC200P

Now it’s time to take a closer look at the comparison between the EcoFlow Delta 2 vs. Bluetti AC200P. This section includes the specs and some explanations so you know what the numbers actually mean.

If you want to gain more insight, check out our post on how to understand power station specs. 

• Battery Capacity
• Inverter Specs Compared
• Charging Times
• Other Features
• Final Verdict

Battery Capacity

Not only is the battery one of the most important parts of any power station, it’s also the spec that divides these two options the most. The Bluetti AC200P has a 2,000Wh battery while the EcoFlow Delta 2 battery is 1,000Wh.

The battery capacity determines how long you can run your devices. If you want to provide 500W of power and you have a 1,000Wh battery, you can plan on less than two hours. And this is fairly easy to figure out: Divide the battery’s Watt-hour rating by the Watts of the devices you power to see how long the power station will last. Then take off about 20% because every electrical system has inefficiencies and batteries can’t use 100% of their capacity.

The calculation is Wh / W = hours, then take out about 20%.

Both of these models have the ability to add more capacity with external battery packs. This can be quite useful. And once again, Bluetti’s specs go above EcoFlow’s:

• Bluetti: Total capacity max is 8,144Wh with up up to two B300 Batteries
• EcoFlow: Total capacity max is 3,072Wh by adding one Delta 2 Max Smart Extra Battery

As expected, Bluetti’s full system specs go far beyond that of this EcoFlow. There’s just no way around it, the Bluetti battery capacity is larger than this EcoFlow.

If you step up to the EcoFlow Delta 2 Max, then you get 2,048Wh internal battery. This internal battery is basically equal to the Bluetti AC200P or AC200MAX. But once again, you can only go up to 6,144Wh with two extra EcoFlow batteries. Still not meeting the 8,144Wh of Bluetti.

As far as battery chemistry goes, these all use LiFePO4 cells. These are excellent batteries that can last a very long time. They are rated to keep at least 80% of the capacity through at least 3,000 charge-discharge cycles. That’s 8-10 years.

Battery Verdict: Bluetti is the clear winner in battery capacity with the single-unit capacity double that of the Delta 2. The more expensive EcoFlow alternative, the Delta 2 Max, hits the same 2kWh battery capacity, but still can’t keep up with the max system size using extra battery packs. There’s no beating the Bluetti battery capacity in this group.

Inverter Specs Compared

The next major spec to look for is the AC inverter. This is the amount of energy that the power station can provide through the normal 110V120V outlets, like you’d find at home. The AC inverter’s job is to turn the direct current (DC) energy from the battery in the alternating current (AC) that some devices require.

The more watts the AC inverter is rated for, the larger devices it can power.

The Bluetti AC200P can deliver up to 2,000W continuously, while the EcoFlow Delta 2’s inverter is rated at 1,800W. These are very close ratings, but the Bluetti stretches ahead.

AC inverters also have a second rating for very short surges of power needed for some devices when they start. This is the peak or surge rating. And here’s where Bluetti stretches even higher with an impressive 4,800W peak rating. EcoFlow Delta 2 only has 2,700W peak.

The alternatives from both brands go above 2,000W, this time with the EcoFlow Delta 2 Max stepping ahead with 2,400W.

But EcoFlow has two unique advantages with the AC inverter design that Bluetti does not:

• UPS / EPS: These EcoFlow models are designed to be used as constant backup power supply sources. This means you can keep them plugged into the wall to power your critical devices. If a power outage happens, they will switch to internal battery power within 30ms.
• X-Boost: This adjusts the voltage to offer higher watts above the inverter’s continuous rating for a longer time. This is fine for many simple devices, especially those with simple electric motors. But you don’t want to run sensitive electronics on X-Boost.

Inverter Verdict: The Bluetti AC200P with 2,000W continuous and 4,800W peak is above the EcoFlow Delta 2 with 1,800W. But it’s a pretty tight race here. When including both alternatives, the advantage flips to the EcoFlow Delta 2 Max with the highest of all 2,400W, plus the EPS function and the special X-Boost mode.

Charging Times

You don’t want to wait forever to let your power station charge. Whether you’re prepping for an adventure and recharging at home, or you’re already away from the grid and using solar, these power station recharging times are very important.

The inputs are rated in watts. You can get a rough estimate of the charging time by taking the battery’s Watt-hours and dividing by the charging Watts. Then add about 20% because the battery management system will usually slow down charging when it gets to 80%. It’s Wh / W = Hours, plus 20%.

The specs here are sort of all over the place. If we just stick to the two power station’s were focused on comparing here, the EcoFlow Delta 2 vs. Bluetti AC200P, we have:

• Bluetti AC200P: AC charging rate is 500W and solar is 700W, which means about 5 hours from an outlet and 3.5 hours from solar.
• EcoFlow Delta 2: AC charging rate is 1,200W and solar is 500W, which means about 1 hour from an outlet and 2.5 hours from solar.

The EcoFlow looks like it has the advantage here. But don’t forget that its battery is half the size! Even the slower solar rate is a shorter recharge time.

There’s no doubt though, the Bluetti AC rate is a little slow. The solar is about what you’d expect. And getting 700W of solar panels for this size battery is just about right. Not many people would want to get more than that. You can calculate your solar panel needs to see if you would.

However, if you include the EcoFlow Delta 2 Max, then it blows away Bluetti with 1,800W AC and 1,000W solar. It really is one of those situations where the more expensive power station has its benefits, shown in yet another category.

Note: If charging speeds are crucial, then the Bluetti AC200L is the right choice. Yes, another Bluetti AC200 option. It’s nearly identical to the AC200MAX except it has faster charging and 20ms UPS function. But the AC200L lacks a high-amp DC output and wireless charging pad.

Charging Verdict: While the EcoFlow charges in a shorter time, the Bluetti charging specs are entirely sufficient. And considering Bluetti’s battery being double the size, it’s not such a bad deal. The AC outlet charging rates just mean you’ll have to think ahead a little bit. Solar should be more than enough for more people as you are unlike to want more than 700W for this size power station anyway.

Other Features

The Bluetti AC200P and EcoFlow Delta 2 have many small differences in features when you start to dig deep. The extra year of warranty coverage for EcoFlow can be a very big deal, but the AC200MAX matches it.

If you want a lighter model, the EcoFlow Delta 2 is better. Thanks to its smaller battery, it weighs 27 lbs (12 kg), less than half the Bluetti at 60.6 lbs (27.5 kg). The EcoFlow size is also smaller.

Having the outlets and ports to connect your devices is another feature to consider with this power station comparison. And here are the highlights worth knowing:

• USB-C Ports: EcoFlow has 2 ports both with up to 100W (pretty high powered) while Bluetti has 1 x 60W port.
• AC Outlets: They both have an incredible 6 outlets for AC devices. The Bluetti AC200MAX has a 30-amp AC outlet.
• High-Amp DC Output: Only on Bluetti models, not these EcoFlow units. If you want to power a DC fuse box, Bluetti is the choice.
• Wireless Charging Pad: Bluetti includes one 15W pad on top of the unit for cable-free charging. Not on EcoFlow

Other Features Verdict: The Bluetti AC200P has the DC output and wireless charging pad, while the bigger AC200MAX is the only one with a 30-amp AC outlet. These are better for RVs. But EcoFlow has a longer warranty and better USB-C ports.

Final Verdict

There’s just no doubting the Bluetti AC200P is the better choice when compared to the EcoFlow Delta 2. The built-in battery is double the capacity, it has a better AC inverter, and it comes with some impressive other features like a DC output and wireless charging pad.

But as a model that’s basically just a newer replacement, the Bluetti AC200MAX is the best choice of all. It has basically the same features as the AC200P, but adds a 30-amp AC outlet, perfect for adding solar power to RVs or using for other heavy-duty devices.

The EcoFlow Delta 2 does have a longer warranty and faster AC charging rates. It’s inverter also has the EPS and X-Boost functions to reach up toward the Bluetti’s specs. Yet to match the Bluetti AC200P with an EcoFlow model, you’ll probably want to look at the EcoFlow Delta 2 Max. And due to its significantly higher price, it’s not really a fair competition. And even then, the cheaper Bluetti models both still hold their own.

Final Verdict: Since the AC200P is hard to find, the Bluetti AC200MAX is the best choice, with impressive battery capacity, inverter ratings, and features. It also adds a 30-amp AC outlet that the AC200P doesn’t have. The only reason to go with EcoFlow is if you want to prioritize the AC recharging speed (then look at the Bluetti AC200L).
