EcoFlow’s battery-powered A/C and heater combo is too overblown

The Wave 2 heat pump is very capable for its size, but EcoFlow’s absurd marketing sets unrealistic expectations.

Placement of the Wave 2 is limited by several factors, including the rather short AC power cord and the 55.1-inch (140-cm) long ducts that require five- and six-inch (12.7-cm and 15.2-cm) diameter openings in a window. So, with my expectations reset, I’ve been using the Wave 2 for the last few weeks to cool down a small 500-cubic-foot bedroom and a 364-cubic-foot Sprinter van in central Portugal, where cloudless skies have regularly produced temperatures too extreme for my Scottish ancestry. That wasn’t enough juice to keep the A/C running all night in a mix of max and eco cooling modes, so I had to plug the Wave 2 into the much larger solar generator I carry to power things like my van’s lighting, induction cooktop, and coffee maker.
