Dependable on line store

I purchased the Delta Max 2 and then this smart extra battery to go with it from Off Grid Stores. Delivery was right on time and the ordering was convenient at their web site. They had the lowest price that I found and had no problems. I am very satisfied with the EcoFlow products and hoping for many years of usage.

This is great addition to the ecoflow 2 max👍🏾

Ecoflow Delta 2 Max extra smart battery

Purchased my Delta 2 Max with 2 extra batteries and (2) 400 watt solar panels. . That just in case we had some type of an EMP or grid failure, that not only I, but also my wife, could handle the weight and easily set up the system. That after consultation with Tom Cormier of Off grid Stores, decided this system would work well for us. All components are in a Faraday cage charged up and ready for action. This was all to compliment my natural gas powered whole house generator and two smaller units. That should there be a long term event, then most likely the grid will be down, thus no natural gas, no gasoline for the other gen sets. That along with our other preps we feel this setup should sustain us for an extended event. Great peace of mind.
