EF ECOFLOW DELTA 2 Max Power Station Extra Battery, 2048Wh LiFePO4 (LFP) Battery, Compatible with DELTA 2&DELTA Max 2000&DELTA 2 Max Outdoor Generators

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.

Hurricane helene hit my small country town. We never experienced nothing like that. 18 days without power and some even more. It was getting very costly running the gas. Generator. I got the delta max 2 with solor panels. Its is awesome. And with the extra battery made it a blessing. I am actually using the 2 to help with my electric bill. Can't wait to summer and see how much my power bill will drop.

I purchased the Delta 2 Max Extra Battery to extend the capacity of my EcoFlow Delta 2 1024Wh portable power station. By adding the Delta 2 Max Extra Battery, I increased my backup power capacity to 3072Wh. Both units use Lithium Iron Phosphate (LiFePO4) batteries, offering a lifespan of up to 10 years with over 3,000 charge cycles. The extra battery weighs approximately 43 pounds, including the connection cable. I received the extra battery within five days of placing my order. Overall, I am very satisfied with the EcoFlow products I have purchased.

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 )

Wow! This thing is awesome....we can go offgrid and run our refrigerator and use our electric skillet with no worries...also upgraded and bought some extras so we can do more days!

Purchased. The battery is working as expected.

My first battery was misdelivered by FedEx to the wrong address and never received (no surprise). However, after contacting the vendor, they were very responsive and immediately shipped a replacement. Five stars for the customer service. Upon receipt, the battery worked as expected and met my needs.

Great Battery. Expensive yes, but high quality. Heavy, also yes about 45 lbs. Keep it out of the sun, don't get it wet. Lithium batteries in general are dangerous when not properly stored or taken care of. So take care of it and it will take care of all you're energy needs. Charges super fast!! there are 2 modes on the back, high (wall socket) or slow (solar or cigarette lighter). The ECOFLOW app is also very cool, you can adjust the power input which I use while charging on the road via an inverter, I use to charge with the cigarette lighter cord at 100 Watts, but it takes forever at that rate, now I got it bumped up to 400-600 watts while I drive (Class 8 Semi) and Its fully charged in a few hours.
