Description
EcoFlow DELTA 3
Six AC outlets, one total output rating.
The DELTA 3 pairs 1024Wh of LFP storage with 1800W total AC output and a separate 3600W surge figure.
Choose the station around the devices and connections you actually need. Stored energy, output limits and the selected package each answer a different part of that decision.

Build the setup around these details.
Battery capacity: 1024Wh Capacity is the stored-energy budget. The connected load and system losses determine how that energy is used.
AC output: six outlets, 1800W total, 3600W surge Check the connected equipment against the rated output and any separate surge or waveform requirements.
USB-A: two ports, 18W maximum Compare the device, port and cable requirements when choosing a direct charging connection.
Plan the load and the energy budget.
The capacity figure does not promise a fixed runtime. Connected devices, their operating patterns and conversion losses affect operating time. Check voltage, rated output and startup demand before connecting an appliance.

Before you choose
How should I compare capacity and output?
Capacity describes stored energy. The rated output and connection limits determine which loads can be connected; any surge figure is a separate short-term specification.
Can I assume a fixed runtime?
No. Runtime depends on the connected load, operating pattern, conditions and conversion losses.
