River 2 Pro's excelence

This is my humble evaluation of ecoflow barand product. I have been using River 2 Pro device for about 2 and half years and this device is a great thing. During blackouts in Ukraine I managed to keep gas-heater ON for more than 6 hours straigth and battery is still performing excelently. All you need is following instructions, e.g. keeping the station charching up to 90 and not lower than 20% (I had to decrease to 15%, due to 768 Wh in use only). So now I am looking for Delta Series device with hope and no regrets!
