The above table shows what the EcoFlow Delta and Bluetti EB240 can power and for how long. I estimated these running times by factoring in an 85% inverter efficiency for AC-powered appliances. The running times range from 100% to 80% DoD (depth of discharge).
  • If you intend to use one of these power stations for appliances rated over 1,000W, then the EcoFlow Delta is the best option.
  • If you see yourself using your power station for smaller power needs (below 1,000W), then the Bluetti EB240 is the best option because it can run your appliances/devices for longer durations.

Port Options

The importance of a solar generator’s ports cannot be overstated. More ports can result in a more comfortable use. The Delta 1300 has a wide variety of ports for indoor and outdoor use.

It consists of six AC outlets, two USB-A, two USB-A QC, two USB-C ports, and a car output. This number of outlets is impressive and useful for many individuals.

The Bluetti EB240 has its 12V and USB ports on its front side and its AC ports on its rear.

Verdict: The EcoFlow Delta has more ports than the Bluetti EB240. It has four more AC power outlets, one more USB-C port, and although they have the same number of USB-A ports, the Delta has two quick-charge USB-As and two regular USB-As while the EB240 has four standard USB-As.

Charging Speed

One of the most notable features of the EcoFlow Delta is its recharge time. It can charge from a wall socket from zero to 80% in only one hour.

BLUETTI 2400wh Solar Generator,EB240 Potable Power Station with 2pcs SP200 200W Foldable Solar Panels Included,2 1000W AC Outlets Lithium Backup Battery for Outdoor Van Camping Home use Emergency
Bluetti sells the EB240 with solar panels in a kit. This kit specifically has two 200W solar panels.

This feature is impressive because other similar solar generators take up to 25 hours to reach that battery level. For a full charge from the wall outlet, the power station takes an hour and forty minutes.

As for solar charging, the charge time listed is approximately 4-6 hours with full sun and 440W of solar panels.

The Bluetti EB240 charges between 6-8 hours when using the recommended solar input (500W). Compared to the Delta, the 240 has a faster charging speed due to its 500W max solar input.

But since the battery in the EB240 is much larger, the overall charge time is longer. The charging rate of the device makes it more comfortable and enjoyable for the users because they can use the system more often. 

From the wall, the EB240 recharges from zero to full battery in about 12 hours. This is significantly longer than the Delta. Even taking the larger battery of the EB240 into consideration (dividing the EB240’s battery by two to equal about the same battery size of the Delta), the Delta charges nearly three times faster from the wall outlet.

Verdict: The EcoFlow Delta has a better overall charging speed compared to the Bluetti EB240. However, the latter still has a great solar charging speed and actually outperforms the Delta by 100W more solar input. Due to the Delta having much faster AC charging, it wins this category.

Battery Longevity

The durability is a function of the build, and most importantly, the life cycle. One cycle is the period it takes to drain a fully-charged battery and recharge it over again. The EcoFlow Delta has 800 cycles to 80% capacity, which proves it is a highly durable solar generator indoors and outdoors.

The Bluetti EB240 has a lifespan of over 2,500 cycles, which proves it has an incredibly high durability level. If users were to charge and discharge the battery in a day (which is relatively difficult due to its size), it should last for seven years of use daily.

Verdict: The Bluetti EB240 has a mind-blowing lifecycle rating. It is much higher than the EcoFlow Delta’s 800 cycles. The EcoFlow Delta is not an excellent device for heavy daily use.

Although the EB240’s li-ion cell type is impressive compared to similar models, LiFePO4 batteries are typically the longest-lasting batteries found in solar generators today. I wrote a post of the top models with this battery type if you’d like to compare them with the EB240 and Delta, found here: 6 Best LiFePO4 Solar Generators (Stats, Pricing, and Analysis).

RV Connectivity

Both solar generators are undoubtedly excellent choices. However, the final choice boils down to your budget and the purpose of the generator you’re purchasing.

Many users may find some additional features unnecessary based on personal preferences. For instance, people who don’t need to power many devices may not care as much about the number of ports as someone who intends to charge various appliances. Even though the Bluetti EB240 may not be the best choice, many advantages come with purchasing the solar generator.

For me, I would choose the Bluetti generator because I will mainly be using it for home backup power. Since its battery is twice the size of the Delta, it will last longer. I do not need it for anything other than a refrigerator for large appliances, and the USB-A outlets work fine for my situation.

If you like portability and could use power on the go, then the EcoFlow Delta is definitely the better choice for you.

There are several next-generation solar generators from both companies mentioned in this comparison.
