Terrible Experience

After buying the EcoFlow DELTA 3 Max Plus, I sought to increase the storage with an EcoFlow DELTA 3 Max Plus Smart Extra Battery. However, it was out of stock. After an endless wait, I finally decided to go for the EcoFlow DELTA 3 Series Smart Extra Battery but then realized I had to buy an adapter. And guess what? ‘OUT OF STOCK!’ It’s anyone’s guess whether this battery is worth it or not.

Great product

Using this with the PowerStream,for both power storage and sending electric to the house base load.
Working really well very happy!
