Awaiting smart batteries.
Very easy set up and charging. The wheels are sturdy and the wireless interface worked very well. Hooked up to the delta pro and smart generator also seemless. Had to use it for a power outage for 12 hours and worked running TV, internet and refrigerator and extra freezer. No issues at all. Great product
Yes, you have the power, no it is prepared for times if power goes out and we can sustain minimum essential for long periods of time
I really like the Delta Pro extra battery but it has no inputs. How hard would it be to add some functionality and it would even look better? The battery comes as advertised. I would still recommend this extra battery to a friend because it is awesome. The charge rate is very fast (about two hours from one third charge). The price is right and quality is outstanding. It is super easy to use, my 8 year old grand daughter had it up and running in no time. Even my wife thinks this is cool. The product reviews just don't do it justice. I compared it to the other main players and they just did not add up. BLUETTI didn't even come close when compared to ECO FLOW DELTA PRO! I live in Albuquerque New Mexico and we have lots of sun here so I also bought two solar panels and that's the main way I keep these two bad boys charged (my ECO FLOW Delta Pros).
This is the greatest thing since sliced bread for backup power nothing better today.
