This unit was purchased to provide power to a shed that would be very costly to connect to the mains . It was bundled with the EcoFlow bi face 220w solar panel.
Both units arrived within the original delivery timeframe which was good - though communication from Toll was limited to an email an hour or three before delivery on the day of delivery , an SMS would have been more useful , and a contact number for Toll which was not provided . EcoFlow customer service were very good in providing information on the delivery of the solar panel when I called them .
The Delta 2 Max charged up ( from AC mains) and connected to Bluetooth and wi fi seamlessly , and the firmware update was really smooth. I have not had an opportunity to use it for an extended period of time , but the USB DC power out has charged a couple of devices . AC power out is functional, but there is a glitch / feature in that the display of AC wattage being consumed is not triggered until 40-50 Watts (?) is being pulled , though the time remaining on the battery adjusts when a device is plugged in and switched on , even though the wattage being used stays displayed at zero both on the device and the App. In contrast USB DC wattage is displayed as low as 4W .
The solar panel has yet to be used as it arrived only yesterday slightly damaged and I am waiting on EcoFlow customer services, so a review on how both devices function together will have to wait .
