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. 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.

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.

Inverter size

Most companies are conscious of the sizes of their inverters. However, please note that this section doesn’t refer to the generator’s actual dimension but the power output of the AC ports. The Delta can power most heavy-duty tools under the power rating of 1,800W, with a 3,300W surge.

The Bluetti EB240 is a highly durable solar generator with a power output rating of 1,000W continuous and 1,200W surge. When the two AC outlets are utilized, the power divides based on the connected appliance. For example, two devices connected to the AC ports will each get a maximum of 500W of continuous power. This inverter size is excellent for household devices like blenders, TVs, desktop computers, and laptop charging.

Verdict: You can power more power-intensive household appliances and heavy-duty tools using the EcoFlow Delta solar generator. With 800W less continuous discharge than the Delta, the EB240 may be an issue with microwaves, portable heaters, and portable electric stovetops. The Delta 1300 clearly wins this category.

A solar generator’s portability is one of the most important factors to keep in mind before purchase. Fortunately, most of the solar power stations in the market are made to be lightweight. The EcoFlow Delta weighs 30.9 lbs, which isn’t heavy for its technical specifications.

The Bluetti EB240 has an overall weight of 48.5lbs, which is relatively heavy, but the much larger battery makes it competitive compared to generators with similar battery sizes. The generator may be challenging to carry for individuals engaged in outdoor activities.

Verdict: Regarding the portability of the solar generators, the EcoFlow Delta has a lighter weight and proves to be more compact. Hence, it’s best to go for the Delta.

Customer Support

Aside from the technical benefits of a solar generator, customer support is an important aspect to consider. If there are complaints, it is required that the customer service is reachable and highly responsive. Users can reach EcoFlow customer support via their email ([email protected]) or via the telephone (+1(800)-368-8604).

Unfortunately, there have been complaints about the customer service that EcoFlow provides. According to specific customer reviews, they are quite unresponsive to complaints in some cases.

Bluetti has an exceptional customer support team. Users contact the support team via email ([email protected]) and through telephone (877-242-2792). According to some reviews, customers seem deeply impressed by the customer service that the company provides as a whole.

Verdict: Since the Bluetti EB240 has better customer support, it wins this category.


Both of the 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.
