To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. They won't come apart accidentally, and the battery adds a handle to the back that makes for easier carrying, though the two combined are heavy at almost 50 pounds. If your home or living space can accommodate it, a window air conditioner will always be a powerful and affordable way to cool down a room. It mostly hovered around 400 watts in the standard mode, and I measured sound at around 50 decibels.

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. The EcoFlow app is generally slick, but I have had to install three firmware updates for the Wave 2 in the two months I’ve had it.It's rated at 5,100 British thermal Units (BTU) for cooling and 6,100 BTU for heating, and works best for rooms up to 107 square feet in size. With lower global warming potential and no ozone emissions, it’s the ideal way to stay cool and comfortable compared to traditional refrigerants while reducing your carbon footprint.

Its swappable battery allows for cool or warm air anytime, anywhere, with the flexibility of multiple charging options, making it the perfect tent, RV or camping air conditioner. This also means it runs quietly, albeit the end with the charging outlets gets a bit warm when it’s in use. Drop 10 °C from 35 °C for 10m³ in 5 min with 5100 BTUs of cooling, and raise 10 °C from 20 °C in 5 minutes for 10m³ with 6100 BTUs of heating in optimal running performance.

Not only does this mean it trails awkwardly – admit it, you’ve already lost the supplied cable winder that clips into the back edge of the unit – on the floor, but also cannot be replaced to a region-specific cable if you take the portability a bit too literally. Whether you're moving it from room to room or taking it on a camping trip, the EcoFlow Wave Air Conditioner is always ready to provide a cool breeze wherever you need it. It will, however, intermittently emit all kinds of grinding and squealing noises- the sort of noise profile that makes you wonder if it’s not going horribly wrong. It hovers closer to 300 watts and around 40 decibels, and the battery keeps it running for up to eight hours. I was able to get all sorts of interesting data from the WAVE 2 (such as compressor RPM, battery level, temperature and much, much more) which I will be attempting to graph over the next few weeks (weather providing).

It is possible that an exemption from VAT pursuant to Sec 12 para 3 German VAT Act is applicable for the selected product. If you don’t know what this means, you’re probably fine since your router probably serves both bands either individually or merged into a single network. At 12 I switched from Max to Eco and thus began around four hours of the compressor cycling on and off and on again, sending the ambient temperature oscillating between around 23 and 18c respectively. If you just want to cool one room in your house, a traditional freestanding air conditioning unit probably makes more sense. This flexibility allows you to enjoy cool or warm air anytime, anywhere, powered by renewable energy sources.The EcoFlow WAVE 2 Portable Air Conditioner is a must-have for individuals who are always on the go and in need of a reliable and convenient source of cool air. There’s a huge battery connector and a solar connector but you can’t remove the power cable when using it on battery. Again, that’s good for smaller rooms; if you’ve got a very cold space or larger room, you may want to look at one of our best electric heaters instead. With snap-on tubes, you can extend cold air reach from outside or keep the AC inside while directing hot exhaust through detachable pipes. Note that if these inputs have low or unstable voltages, only fan mode is available; to guarantee air conditioning and heating, the battery is needed.

When this is full, the manual drainage mode should be engaged, via the app or by pressing and holding the fan button. I will also evaluate the WAVE 2’s portability by lugging it around the house and using it in its various configurations to cool other rooms. There are intake vents on the front and back, an exhaust vent on the top rear, and cool air (warm in heating mode) flows out the top vent at the front. 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. Used inside, two pipes should be run to a window: one draws in cooler air from outside; the other sends hot air out; cold air comes out the vent at the front.Pair your WAVE 2 with an EcoFlow DELTA 2, and you'll get an astonishing 7 hr run time in WAVE 2 Eco Mode.
