   EcoFlow DELTA 3 Extra Battery: A Must-Have for Extended Camping Power
   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.

   Double the capacity in no time
   The quickest way to double the capacity of the already well designed Delta 3 Plus is to add this extra battery to it. Its only takes seconds to do so. It is hassle free and works immediately. Its a simple plug and play. My app found the new device and link them together without me doing anything to it. After plugging it in, i charge both units to full 100% to calibrate both devices. I only have to do it once and it balance itself out. Now it is draining at perfect in-sync percentage. Another improve is the extra battery cable is not in the back. It is not as visible as the Delta 2 series. Another thing is the extra battery stack on top of main unit like a champ. Its is not moving a bit. It feel so stable and pleasing. Definitely a well thought desgin.

   Excellent! Pairs perfectly with the D3+. EcoFlow nailed it.
   Purchased this to double the storage capacity of my Delta 3 Plus. Its sleek and pairs perfectly. I use the D3+ to power my entire work-from-office as well as on the road to power my camper and mobile office. Having twice the storage allows for much longer run time when solar isn’t available. Having a quiet power source that can be run indoors and recharged by solar panels is superior to loud gas generators in virtually every way. In my view EcoFlow has nailed the sweet spot for power, affordability, and portability with the The Delta 3 Plus and Extra D3 Battery. Love it! 5 stars.
