Compared to many power stations on the market, the Bluetti EB240 has two AC outlets, one USB-C PD outlet, four USB-A outlets, and one DC 12V outlet. With this number of ports, users can charge several devices simultaneously.
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.
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
There are several aspects to analyze when choosing the best generator for RV connections. The EcoFlow Delta doesn’t come with a specific RV outlet. However, this is not necessarily a bad feature since it can be recharged via RV input.
The Bluetti EB240 does not come with an RV outlet either. Similar to the EcoFlow Delta, it can be recharged by using the RV input (12V DC).
Verdict: Most solar generators with similar technical specifications to the Delta and Bluetti EB240 don’t come with RV outlets. However, generators like the Titan are known to have an RV plug capable of handling up to 30 amps of power.
