Expandable Capacity

DELTA 2 expands up to 2048Wh with smart extra battery, keeping your home powered on in any emergency.

Convenient Recharging

DELTA 2 and its Extra Battery charge and discharge in unison. Recharging from portable solar panels, AC outlets, or our Smart Generator is easy.

Fast Recharging

Charge up with DELTA 2 from 0-80% in 80 minutes and 0-100% in 130 minutes with AC input.

Internal Storage Compartment

Power Multiple Devices

DELTA 2 fits with every port you'll ever need to power any devices anywhere, so you will always feel right.

Control from anywhere

Double your energy storage for less cost

1kWh expandable capacity to fit your energy storage needs, ideal for home backup, RVing, outdoor adventures, and everyday use. Much more affordable, it costs up to 30% less than a power station of the same capacity.

10-year lifespan with an LFP battery

With its upgraded LFP battery chemistry, the DELTA 2 Smart Extra Battery 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. That's 6× longer than other power stations with a similar capacity and output.

Fast Recharging

Charge up with DELTA 2 from 0-80% in 80 minutes and 0-100% in 130 minutes with AC input.

Easy to use

There's no setup. Just plug it into your power station for more energy storage. Using the EcoFlow app, you can charge and monitor the DELTA 2 Smart Extra Battery with ease.

Stackable, space-saving design

Featuring an ergonomic, compact design, the DELTA 2 Smart Extra Batteries can be securely stacked on top of power stations and each other to save space and minimize clutter.

I just opened it today. Will charge soon. Heavy but manageable. I love that I can use solar panels to charge. I purchases the main unit and the back up battery. Helpful to use with our small refrigerator to keep medicine and food cold. Many uses Incase of a disasters specially earthquakes and occasional power outages. Will do a follow up after charging and trying it out. So far I feel satisfied with this choice.

Well I am not going to try to write a technical review, I will leave that to people who know more than I do. But after reading those technical reviews and studying other solar products, it was a no brainer to pick Ecoflow. I wanted a very portable system that had a long life span and high efficiency rating. The Delta 2 was perfect for my needs. I can also say that for someone that is not technically inclined that the set up and use of the Ecoflow was very easy and I am happy with the expandability of the product . Also, I was surprised that even on a cloudy day the Ecoflow was generating power. Now I am tempted to go with a whole house system from Ecoflow.
