    • EcoFlow DELTA 3 Extra Battery: A Must-Have for Extended Camping Power
Style: Delta 3 Series Extra Battery

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

    • Add an extra 1kwh to your Delta 2 battery system easily.
Style: DELTA 2 Smart Extra Battery
Adds an extra 1kw to my Delta 2 and works great. Would be 5 star if there was a secondary position for charging port. Useing this in my Jeep for off grid adventure I don’t stack them, so the connection port being on the side is kind of annoying in having to space/connect them. I may try and stack in rear and come up with a tie down/strap system to work around. Otherwise, it works beautifully and 2kw is the perfect t power combination for work/play/internet/fridge on the road in combination with the EcoFlow Alternator 500w keeping these charged on the road. The Size and battery life is the exact same size as the Delta2. The top compartment being a place to store the connecting cable when not in use. Value wise, these aren’t the cheapest but they’re reliable and safe to use. That’s what matters the most to me. DIY systems can be fun but also trouble. This shows up as a second battery on the mobile app. ... show more

    • Good Extra Battery for Delta 2 with limitations...
Style: DELTA 2 Smart Extra Battery
I purchased this addon battery due to the Delta 2 only having 1024 watt hours, I wanted to double my watt hour amount and I was fine with the amount of ports and outlets on my main Delta 2 1024 wh unit as is. Here's the catch. The addon battery has no inverter for outlets which I expected, but it also has no wall outlet charger port to charge the unit separately. You have to daisy chain the addon battery to the main delta 2 unit and tether them with the side port used by the alternator charger. It's not ideal, but it's what you'll get for buying an entire new delta 2 or delta 2 max. The firmware is designed to pass battery charge amount between the 2 units when connected together and not using a wall outlet ac charger input. This is information I wish I had knew before purchasing. It's a solid unit for the most part, but just know the limitations of what you're buying. ... show more
