The latest LiFePO4 (LFP) battery chemistry found in EcoFlow's EcoFlow DELTA 2 and EcoFlow DELTA Pro should last for 10 years or more before a noticeable decline in performance.

With its upgraded LFP battery chemistry, DELTA 2 Max has a lifespan of 3000 complete cycles until it reduces to 80% capacity. You'll get pretty much 10 years of power, even if you use it every day.

EcoFlow generally offers higher capacity and more advanced features, such as fast charging with X-Boost Technology, multiple AC outlets, and the ability to expand with extra batteries, which can make them more expensive than Jackery power stations.

EcoFlow is a San Francisco based battery manufacturer. Their factory is based in Shenzen, China, where over 80% of the world's batteries and computer chips are made.

Let's face it, priced at $3,699, the Delta Pro 3 is definitely on the high end of the portable power station market. But if you're looking to build a home backup power solution, want a device to power your RV, or need a ridiculous amount of portable power, this unit is easily worth every penny.

"The EcoFlow DELTA 2 Max Portable Power Station is impressive. It has the ability to charge nearly all appliances in a home in case of a power outage." "EcoFlow's Whole-Home Backup Power Solution is a backup power system that aims to keep a house running without noisy, gas-guzzling generators."

The surges and other electrical noise do pose a threat to the electronics in the unit. Leaving them plugged in 24/7 isn't the be... It's ok and safe.

DELTA Pro has a capacity of 3600Wh. Then theoretically, the run time is 3600Wh divided by 1200W, that is 3 hours.

With an unrivaled capacity of 6kWh, 7200W output, and 5.6kW solar input, a single unit can run your entire home.

Is EcoFlow Delta noisy? ›

Delta Max 2 is quiet. Delta Pro Ultra is near silent. The rest of the Delta series have louder fans.

EcoFlow says the Delta Pro will still be at 80 percent capacity after 3,500 cycles, which would take almost 10 years if you were to charge and deplete it every day.

Disadvantages: While the line to line voltages will be equal, the line to neutral voltages will have two phases being equal and one phase being 1.732 times larger. Unbalanced single phase loads can cause voltage fluctuations and additional, uneven transformer heating.

Most Li-ion batteries have an expected lifespan of around 500 cycles. LiFePO4 batteries have higher expected lifespans and can undergo thousands of cycles before the capacity is heavily affected. For example, the EcoFlow DELTA 2 Max is rated for 3,000 cycles before storage capacity diminishes to 80%.

Using RIVER 2 Max six times a week, 3000 full 100% cycles will last 9.6 years until it drops to 80%.

EcoFlow says that the battery is designed to last for 800 cycles at 80%+ capacity.
