This smart, portable AC is actually a 3-in-1 system: it functions as an air conditioner, heater, and dehumidifier. It can run while plugged in or on battery power, though you can also charge it with solar panels. This makes it a useful companion for RV users or campers, but it can also be helpful in a pinch during power outages or heatwaves.
In my case, I put it through the ringer during a heat wave this summer, when my central AC was too strained to perform well. I have a room in my home that isn’t connected to the central HVAC, which is, unfortunately, adjacent to my kids’ playroom. With the kids at home for summer break and both parents working from home full-time, I set up the Wave 3 in the playroom to help the little ones stay cool and comfortable.

<!–>
The Wave 3 isn’t intended to be the most powerful portable AC on the market, as it has a 6,100-BTU cooling capacity and a 6,800-BTU heating capacity. Instead, EcoFlow made the Wave 3 for portable comfort, independence, and convenience. The unit is smart, allowing it to work with Wi-Fi and Bluetooth, so you can control it and view its status from your phone.
While this portable AC fills a supplemental gap and can be used in a pinch during heat waves, it isn’t an emergency device. The EcoFlow Wave 3 is ideal as a comfort measure – a temporary fix rather than permanent climate control.
At 41% off, this deal makes the EcoFlow Wave 3 stand out from competing portable ACs with fewer features, which typically cost between $600 and $900.
