Of course, Delta Pro and its lite variant Delta Max and EP500 and its pro variant EP500 Pro are going to be the next big players in the portable power market. Here, we have would like to have a detailed look at them in our EcoFlow Vs Bluetti article. Stay tuned to have a complete insight into the new EcoFlow and Bluetti devices.

Storage Capacity and Output

EcoFlow Delta Pro is basically a 3.6Wh power station, but you can take its capacity to a huge 25kWh for emergency power to run an entire household for around 13 days. Well, for expanding its storage capacity, the brand offers you multiple options, which include the Smart Extra batteries and the EcoFlow gas generator.

When it comes to the inverter, a single Delta Pro packs up a 3600W powerful unit under the hood.

But by pairing two Delta Pros together, you can double the inverter power to a massive 7200W @ 240V. The brand offers a Smart Home panel and a Double Voltage Hub to let you enjoy the 7200W high power respectively in home circuits and off-grid applications.

By the way, its lighter variant Delta Max is a 2016Wh scalable power station with a 2400W inverter and it has got a 3400W X-Boost power. This is an option for budget-conscious users to get a highly modular power station.

Update: Bluetti’s Newly Launched B230 and Upcoming B300 Extra Battery Modules Are Compatible with EP500. You Can Use Them To Further Add to the Storage Capacity of the Heavy-Duty Machine Using a DC Enhancer Device. 



Meanwhile, Bluetti EP500 and its Pro variant integrate a massive 5100Wh battery pack. You can expand it to double capacity by pairing two units of each model using the brand’s special accessory board.

That said, you can hit the 10kWh mark with two units of either EP500 or EP500 Pro.

In the process, you also get the inverter power doubled. Thus, the 2000W EP500 can deliver you 4000W at 240V and the 3000W Pro variant can deliver 6000W at 240V.

Winner: EcoFlow Delta Pro

Once paired together, the EcoFlow power beast has more output and inverter power.

But to achieve the 10kWh mark, you need to connect two extra batteries to the original. By the way, taken as a single unit, Delta Pro falls short in storage capacity to EP500, but it still has a bigger inverter under the hood. 

Meanwhile, two units of Bluetti EP500 or EP500 Pros can make it up to 10.2kWh.   

Expandability Features

As you see, both the EcoFlow and Bluetti are high-powered expandable power stations. They feature different ways of expanding their storage capacities and inverter power.

In the case of Delta Pro, the brand offers an extra battery pack of 3600Wh capacity.

As mentioned above, you can connect it to the base model via either a home circuit panel or a voltage hub. You can connect up to two extra battery packs to take the capacity to 10.8kWh.


To enhance storage capacity further, the brand has come up with a gasoline generator. Though not an eco-friendly option, you can use it to power up your backup systems in critical and prolonged emergencies.

Meanwhile, Bluetti doesn’t have special battery packs for the expansion of its EP500 and EP500 Pro.

Instead, it has got a Split Phase Box to pair two units of the devices together. Thus, you can double the capacity and AC output of both variants of its heavy-duty power station and enjoy extra juice in the wild.

The box also helps you select 220/240V outputs to make it compatible with a variety of your appliances.

Winner: EcoFlow Delta Pro 

Delta Pro offers seamless scalability, thanks to its extra batteries and a gas generator. It is when the Bluetti has limited scope for battery expansion, and even for that, you need to buy two units of the same device. 

We are not certain if Bluetti’s new B300 and B230 extra battery packs will work with EP500. They are designed for the brand’s other new models like AC300 and AC200 Max

Next, let us have a look at the charging options of the EcoFlow Vs Bluetti heavy power stations.

For solar charging, Bluetti EP500 has got a maximum voltage input of 1200 watts, whereas its pro variant features dual 1200W inputs to support a total solar current of 2400 watts. Fine, with the right amount of solar power, you can get the power stations charged up in five to three hours respectively.

The brand itself has an exclusive 200W folding solar charger for the power stations. You can indeed pair multiple units of the solar charger to achieve the required output for each model.

Likewise, EcoFlow Delta Pro touts a maximum solar input of 1200 watts. With a 98% highly efficient MPPT charge controller under the hood, you can charge the machine fully in four to eight hours, depending on the intensity of sunlight in your location.

Thanks to a voltage range from 11-150V, it can be charged with any third-party solar charger with the needed MC4 connectors. Its lite variant Delta Max has a solar input of 800W Max (11-100V), by the way.

EcoFlow offers a new and highly efficient solar panel, which is a 4-layered mono charger with a higher conversion rate. You can pair multiple units of the same to achieve the total power requirements of both models.

AC Outlet and Other Options

When it comes to AC wall socket charging, EP500 has a 600W AC charger adapter inside, while its sibling packs up a more powerful 1800W AC adapter. As both integrate adapters inside, you don’t need to carry bulky power bricks.

Delta Pro also features a 1800W AC input with a built-in MPPT controller. The 98% efficient controller is capable of juicing up the device in a few hours, and with the X-Boost mode on, it will get charged up rather faster.

Moreover, it comes with other revolutionary charging options. One is a 1800W charging socket to connect it to an EV charging station for a full charge in just a few minutes.

Also, the company has designed a smart gas generator to charge both Delta Pro and Max in extended emergencies. Even if not an eco-friendly option, the 1800W EcoFlow gas generator is highly energy-efficient and less noisy.

Winner: EcoFlow Delta Pro

Delta Pro has a clear edge over Bluetti EP500 with a much reliable solar charging input and a number of other unique and flexible solar charging options like a gas generator, EV station charging, and more. 

Charging Outlets
