One of the most significant upgrades of the WAVE’s newest generation is its heating and cooling capabilities. The original WAVE Portable AC was a powerful unit — but it was limited to only cooling. Anywhere, anytime use:Weighs only 14.5kg without an add-on battery, making it more portable and compact.

With off-grid capability and multiple charging options (including solar), the WAVE 2 Portable AC brings you one step closer to building a smart, sustainable home ecosystem. Final ThoughtsBut if you thought the original was impressive, wait to see what the EcoFlow WAVE 2 Portable AC can do. Most ‘portable’ aircon units are still chunky boxes on wheels, but the EcoFlow Wave 2 is considerably smaller (336 x 297 x 518mm). At 14.5kg, it’s not a light device, but it’s certainly lighter than most air conditioning units. At this kind of size, the Wave 2 can be carried around the house, or out to the car to take away for a camping trip. Battery life on the Wave 2 is very good. Using it in maximum mode, I was able to get more than two hours of use out of the system; dropping down to Eco mode boosted this to just shy of eight hours, although sacrificing some cooling ability along the way.

Highly compact at 20.4” × 11.7” × 13.2” (518 × 297 × 336 mm), you can take WAVE 2 anywhere — from road trips to camping adventures, without sacrificing valuable space in your motorhome, car, or your living room. 27% More PowerfulThe add-on battery also includes 2 output ports (USB-A & USB-C)to recharge all your electronic devices. With the battery attached, mains charging was drawing 743W, which is enough to fully charge the battery in just shy of two hours. Using a 400W solar panel, I got an input of between 100W and 300W, which meant that it took between eight and four hours to fully charge; how much sunlight is available has a massive impact here.
