    • Double the Power!
Style: Delta 3 Extra Battery
Excited to finally have ordered the extra battery. I live in a microcamper full time and realized my power needs were more than I originally expected. The Delta 3 Plus was a great add on to save my vehicles battery, but needing to start the car to charge it was starting to use a lot of fuel. With the addition of this extra battery, the alternator charger (I recommend the 500w for most vehicles), and a solar panel, I'll never be without power again despite my gaming addiction. Just remember the Delta 3 Plus can only take one additional battery ^.^ ... show more

    • Quality of the product as well as the company that I'm dealing with.
Style: Delta 3 Extra Battery
I've had my eco-flow Delta 3 power station for approximately 2 years now and could not be happier with the quality and performance of it but since we sometimes camp for extended. Without the benefit of external it was a no-brainer to purchase the extra battery and double our stored power. The only mistake I made was thinking I needed to purchase a connecting cable as there is one that comes with the extra battery. Could not be happier with this company's products. ... show more

The EcoFlow DELTA 3 Smart Extra Battery has been a fantastic addition to our camping gear. With its extra 1024Wh capacity, it keeps our DELTA 3 Plus running longer, so we never worry about running out of power during our trips. One thing we love is how long-lasting it is. Thanks to its LFP battery, it can handle over 4000 charging cycles, which means it’ll be with us for many adventures to come. Setting it up was a breeze. We just connected it to our DELTA 3 Plus, and the EcoFlow app lets us easily check how it’s doing. Its compact design is a big plus, making it easy to pack and stack with our other gear. Knowing it comes with a 5-year warranty gives us extra peace of mind. All in all, the DELTA 3 Smart Extra Battery has made our camping adventures more enjoyable by providing reliable and extended power when we don’t want to bring our much bigger EcoFlow Delta Pro Ultra. ... show more
