  • QuestionWhat is the wattage output limit of this device for operating a ceramic room heater?

    Asked by Specialk.

    • Answer Thank you for your inquiry. The EcoFlow DELTA 3 Ultra provides up to 3600W of continuous AC output. Compatibility will depend on the power consumption of your ceramic room heater. For example, if your ceramic heater consumes between 750W and 1500W, the DELTA 3 Ultra can typically power it without issue, provided the heater's power draw does not exceed the unit's maximum output rating of 3600W. For the most accurate compatibility assessment, we recommend checking the wattage rating listed on your heater's specification label. Please let us know if you have any additional questions. We'd be happy to assist.

  • QuestionHello, is it possible to use this for table saws and miter saws?

    Asked by Derek.

    • Answer Thank you for your inquiry.​ Yes, the EcoFlow DELTA 3 Ultra can power many table saws and miter saws, as it provides up to 3600W of continuous AC output with a higher surge capacity to handle startup loads from power tools.​ However, compatibility depends on the specific power requirements of your saw. We recommend checking the tool's wattage or amperage rating. As long as the tool's running wattage and startup surge do not exceed the DELTA 3 Ultra's output capabilities, it should operate without issue.​ For the most accurate compatibility assessment, please provide the make and model of your table saw or miter saw, and we'll be happy to verify whether it can be powered by the DELTA 3 Ultra.
