Performance and Usability

EcoFlow Delta Pro 3 in use

EcoFlow DELTA Pro 3

The EcoFlow DELTA Pro 3 stands out with its impressive 4000W output, making it suitable for high-power appliances and multiple device connections simultaneously. Its 4096 Wh LFP battery ensures longevity and reliability, with a lifespan of up to 4000 cycles. The comprehensive range of AC and DC outlets, including high-power USB-C and Anderson ports, provides versatility for various use cases.

EcoFlow DELTA Pro

While the DELTA Pro offers a slightly lower maximum output at 3600W, it remains a powerful contender in the market. Its 3600 Wh battery capacity and robust build make it a reliable choice for heavy-duty applications. The DELTA Pro’s slightly lower weight and compact design compared to the DELTA Pro 3 can be a deciding factor for users prioritising portability.

EcoFlow DELTA 2

The EcoFlow DELTA 2, with its lower price point and 1024 Wh battery capacity, is an excellent choice for users with less demanding power needs. Its 1800W output, although significantly lower than the DELTA Pro models, is still sufficient for a wide range of applications. The DELTA 2’s lighter weight and compact size make it highly portable and suitable for outdoor activities and smaller households.

Connectivity and Smart Features

All three models support Wi-Fi and Bluetooth connectivity, allowing users to monitor and control the power stations via a dedicated app. This feature provides real-time information on battery status, power consumption, and other critical parameters, enhancing the user experience.

Temperature and Environmental Considerations

The EcoFlow DELTA Pro 3, along with its predecessors, operates efficiently across a wide temperature range, making them suitable for various environmental conditions. This adaptability ensures reliable performance whether in extreme cold or heat, which is essential for users in diverse climates.

UPS Functionality

The DELTA Pro 3 and DELTA Pro models boast a swift 10 ms Uninterruptible Power Supply (UPS) feature, ensuring seamless power transitions during outages. This quick response time is crucial for protecting sensitive electronics and maintaining continuous power supply. The DELTA 2, with a 30 ms UPS, provides adequate protection but may not be as fast as its higher-end counterparts.

Noise Levels

Noise levels are an important consideration, especially for indoor use. The DELTA Pro 3 operates at a quiet 30 dB when running at 2000W, making it one of the quieter options on the market. The DELTA Pro and DELTA 2 are slightly noisier but still maintain acceptable noise levels for most applications.


The EcoFlow DELTA Pro 3 sets a new benchmark in portable power solutions with its advanced features, higher power output, and extended battery life. While it comes at a premium price of $3699, its capabilities justify the investment for users requiring robust and versatile power solutions.

The EcoFlow DELTA Pro remains a strong contender, offering substantial power and capacity at a slightly lower price point. It is an excellent choice for users who need a powerful yet slightly more portable option compared to the DELTA Pro 3.

For those on a tighter budget or with less demanding power needs, the EcoFlow DELTA 2 provides a cost-effective solution without compromising on essential features and reliability.

In summary, your choice between the EcoFlow DELTA Pro 3, DELTA Pro, and DELTA 2 will depend on your specific power requirements, budget, and portability preferences. Each model offers unique strengths, ensuring that there is an EcoFlow solution suitable for every need.
