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: Great expansion. About to get me another - 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 .

## 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.

### ⭐⭐⭐⭐⭐ delta2 max
*by D***A on April 11, 2025*

it's a great product for camping or general use around the home. If you are planning a near off grid power solution, move up to delta pro or to delta 3 pro. or completely off grid use delta pro ultra. I love my delta 2 max, i have 2 plus 2 more extra battery. I do plan to purchase 2 more extra battery to complete my solar power system. Customer service sometimes gets you fluster but at the end they get the job done. You also need to pay attention to the item. I have several delta mini. Bought it because it said 1400 watts, but its only 882 capacity watts, to use up to 1400 watts you need to activate boast. however it drains you battery faster. pay attention to which power solution you are purchasing, their are delta 2- 1000 watts ,1300 watts and 1600 watts. also to make it more confusing their is delta 2 1900 watts and 2048 watts. delta max is 2048 watts. I love the minis, great for outdoors, camping. I use both my delta 2 max plus batteries to lower my power bill in san diego, which is the most expensive power company in my opinion.
