Differences EcoFlow Delta 2 vs EcoFlow Delta 3 Plus
Below is a summary of the specifications:
Battery Capacity and Lifespan
When selecting a portable power station, battery capacity is one of the most important factors to consider. Both the EcoFlow Delta 2 and the EcoFlow Delta 3 Plus offer 1,024Wh of battery capacity, which is sufficient for powering a variety of medium-duty devices such as laptops, small refrigerators, CPAP machines, and smartphones.
The EcoFlow Delta 2 uses LiFePO₄ (Lithium Iron Phosphate) batteries, which are renowned for their durability and safety. It provides 3,000 charge cycles before the battery’s capacity drops to 80%, ensuring a long lifespan for everyday use. However, if you anticipate more frequent usage, the EcoFlow Delta 3 Plus offers a longer lifespan with 4,000 charge cycles, giving it more resilience over the years. Both units ensure reliable service, but the Delta 3 Plus outperforms the Delta 2 when it comes to battery longevity.
