EF ECOFLOW DELTA 2 Max Power Station Extra Battery, 2048Wh LiFePO4 Battery

This expansion battery has been a great addition to my DELTA 2 Max setup. The connection process was straightforward, and the unit was recognized immediately by the power station. It provides the extra capacity I was looking for and helps extend runtime for my devices during outages and outdoor use.

This EcoFlow 2Max Extra Battery was delivered today and I am very pleased to say it so far functions very good and nothing was broken or damaged during the shipping and delivery process as before in a previous same purchase. I can confirm that the operation and functionality is exactly as described in the advertisement for this product and additional 2048 Watts to my solar generator system will definitely cover my electricity needs during this upcoming summer months and fire season when the main power supply grid is shutdown for public safety. I would recommend these devices be purchased for your homes in case of any future power outages because they are very efficient and and very easy to use and will save you money and discomfort during the upcoming months. Long story short, the EcoFlow company works with customers to help purchase their products by offering different types of payment plans that are compatible with many budgets so anyone can afford to pay for a important product that will help them during power outages that occur very frequently nowadays. Thank you (I’m pretty sure I will purchase one more extra battery so I can run my air conditioner when the heat is causing the power grid to be shut down and instead I will be enjoying my regular life without disruption and sweating in the heat waiting for the power company to turn back on the grid power supply to every house )

Overall, it’s a practical add-on for anyone looking to expand capacity and extend usage time.

I have the delta 2 and needed more capacity. Although it is not listed or pictured. It came with the connector cord. It arrived really fast. I was able to run my fish tank all night for 10 hours and still had 30% capacity. Now I just need to get my solar panels in the roof to get my tank off grid. Should save me 100$ a month. That's what my edison bill is costing me . I also camp often and bring my battery as a back up for days my solar panel doesn't produce enough . These are petite enough to dig under my dinette. It's saved me twice already now. One day I'll get another expansion pack!!! It's convienent enough that I drag it with me to work some days when I know I'm out on the field all day. I run a small microwave to heat up lunch so I'm not eating cold food like a cave man .

Has not disappointed! All around great sense of security (power backup)if something goes wrong with the electric supply to the house. Have tested it on many different items for hours on top of hours. It is heavy but simply solved by building a cart that holds the station and extra battery (or 2 batteries). Charges quick by AC power. Planning on testing solar charge soon.

The battery is good, The seller shipped the 45W panel and everything is fine. Thanks

Great quality, exactly as described, and arrived on time. Very satisfied with my purchase .Highly recommended!

This power station is hooked up to 800 watts of solar panels in series. Runs the power in a small household office and fully charges daily, with average sunshine. No more concerns over blackouts. Reliable, quiet, well built!
