Our take on the EcoFlow WAVE 3 Portable Air Conditioner with Heater

The EcoFlow WAVE 3 is a portable air conditioner and heater in one 33.7 lb unit, rated at 6,100 BTU cooling and 6,800 BTU heating. It runs from wall power, a compatible DELTA power station over XT150, or the WAVE 3 Add-On Battery, which is sold separately and gives up to 8 hours of runtime. EcoFlow claims about a 15°F drop or 17°F rise in roughly 15 minutes, plus dehumidification, auto, fan and pet care modes, a 44dB sleep mode and app control over Wi-Fi or Bluetooth. It suits van, RV, tent and job-site users who need both heat and cold from one box; against single-function portable ACs it adds heating, but it has no built-in battery, so off-grid runtime means buying the Add-On Battery or owning a DELTA station.
