The battery can take 800 charges before it hits 80% capacity, as it uses older technology. Still, that means that if the battery was charged for three months of the year, once per day, it would take 8.8 years until the battery was at 80% capacity. Enjoy the convenience of cooling and heating right out of the box! It’s the perfect air conditioner for any compact space. ... Enjoy the convenience of cooling and heating right out of the box! It’s the perfect air conditioner for any compact space. Extremely simple to use, requiring no installation or drainage*. EcoFlow’s tailor-made compressor enables WAVE 2 to provide 5100 BTUs of cooling and 6100 BTUs of heating. The air conditioner comes with a user manual that provides step-by-step instructions on how to install it. The entire process takes less than ten minutes, and no special tools or skills are required.

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. In addition to the off-grid charging capability, EcoFlow also uses R290 refrigerant, which is more eco-friendly than traditional refrigerants, as it has no ozone-destruction qualities.EcoFlow is perhaps better known for its power stations, such as the EcoFlow Delta 2, but the company is expanding into a wide range of, primarily, battery-powered products, including the EcoFlow Blade robot lawn mower and the Wave 2, its second-generation portable air conditioning unit. 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 Powerful While the original WAVE Portable AC already had the industry-leading portable cooling capacity of 4000 BTU, the WAVE 2 Portable AC takes it to another level, further widening the gap between EcoFlow and the rest of the market. But if you thought the original was impressive, wait to see what the EcoFlow WAVE 2 Portable AC can do. With EcoFlow’s advanced software algorithm, the WAVE 2 offers multiple modes and app control. It runs quietly (44 dB) in Sleep Mode and up to 8 hours in Eco Mode. This means that the air conditioner can be used at any time of the day or night without causing any disturbance. Experience longer-lasting comfort in your tent, RV, or home with its powerful and portable design. Is the EcoFlow WAVE 2 Eco-Friendly?

BTU heating and 5100 BTU cooling performance for vans, RV, tents, off-grid rooms, or outdoor spacesPair with an EcoFlow DELTA 2 / DELTA Max or their extra batteries and get an astonishing 7-14hr run time in Eco Mode. Compared to using other portable power stations, it’s 28% more efficient. You can also use any portable power station with an 820W input to charge your EcoFlow WAVE 2. Using this battery is neater, as it clips into the bottom and becomes fully integrated. However, if you have a compatible power station, such as the Delta 2, you can buy a cable that links the two together, reusing your existing battery. The first generation of the WAVE Portable AC was a groundbreaking achievement in compact and efficient cooling. But now, EcoFlow has raised the bar and delivered numerous innovations by introducing the WAVE 2 Portable AC. There’s only one real downside to using the unit outside: its onboard temperature sensor is effectively useless, as it’s measuring the outside temperature, not the temperature inside the room. Where you can, then, inside use is best.
