## Description

desertcart.com : EF ECOFLOW DELTA 2 Max Power Station Extra Battery, 2048Wh LiFePO4 Battery | Compatible with DELTA 2&DELTA Max 2000&DELTA 2 Max Outdoor Generators : Patio, Lawn & Garden

Review: DEFINITELY a must have for an add on to 1kwh batteries! - I bought 3 of Delta 2 batteries, along with a Delta 2 Max extra battery to extend one of the batteries out to 3kwh, and a couple river 2 pro and river 2 max batteries (and about 2200w in solar panels). They are extremely handy in a power outage situation (just tested for days after hurricane Milton), for example 1 delta 2 could run my fridge for about 16 hrs, but with the delta 2 max extra battery, that extended it to about 40-45 hrs! Not too shabby, but if you have panels, and there's no sun...well, gas inverter generator works to power them fairly quickly. That being said, I stockpiled about 8kwh in total in ecoflow batteries in addition to 9 panels of varying strengths ranging from 200w-400w each, with the intention on being able to run my fridge, freezer, internet, power some things like tv, computers, etc, but most importantly, being Florida, my portable AC. It did all of the above great (except for the multi-day cloud cover preventing the panels from being useful), but when attempting to use my portable AC, even on a delta 3 plus (same size, but provides 2 solar inputs and more output for ac plugs), it immediately shuts down the portable AC and goes into an overload status. So, it checked nearly every box, but 90 degrees in a house in florida without ac can really really suck. It did power a few 20" box fans nicely, so I made a bit of a swamp cooler of sorts with those instead. All in all, VERY useful during a multi-day outage, but make sure you have an inverter generator to charge them as well. You will use far less gas from your gas generator in charging these and letting them take over primary power for everything that you would using the gas generator alone. The extra battery really is a must have, because it extends the range of the 1kwh and 2kwh batteries significantly! Just don't be tricked by the fact the main battery always says there is input, even when not hooked to AC power or panels.
Review: Works like a charm - 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.

## Features

- Expandable Capacity. Increase the capacity of DELTA 2 Max with an extra 2048Wh.
- Triple the Power. 2-6kWh expandable capacity to fit your energy storage needs. Add up to two DELTA 2 Max Smart Extra Batteries to hit a capacity of 6144Wh. Ideal for home backup, RVing, outdoors or even everyday use.
- Built to Last 6× Longer. Get 10 years of daily use until hitting 80% of its original capacity. That’s down to its LFP battery chemistry giving you 3000+ cycles.

### ⭐⭐⭐⭐⭐ Fantastic Fast Delivery of a Quality Product
*by M***O on February 21, 2025*

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 )
