Key Features
Introduction
Portable air conditioning unit are rarely really that . for sure , they can be put out in winter or cycle from room to room , but they ’re far from what I ’d call portable . That ’s where the EcoFlow Wave 2 comes in .
This is a in truth portable air conditioning unit ( and heater ) , which has an optional bombardment pack and solar input for straight wire - free use , both in the house and out and about . It ’s surprisingly powerful and works well in smaller rooms , although those expect to cool a large space will need to go with a more muscular unit .
Design and features
EcoFlow is perhaps better know for its power stations , such as theEcoFlow Delta 2 , but the company is spread out into a wide range of , primarily , electric battery - power products , including theEcoFlow Bladerobot lawn mower and the Wave 2 , its 2d - generation portable air conditioning unit .
Most ‘ portable ’ aircon units are still chunky box on wheel , but the EcoFlow Wave 2 is well diminished ( 336 x 297 x 518 mm ) . At 14.5 kg , it ’s not a clear gadget , but it ’s certainly light than most air conditioning units . At this kind of size , the undulation 2 can be gestate around the house , or out to the car to take away for a bivouacking trip-up .
Compared to all other melodic line conditioning units , the EcoFlow Wave 2 is designed to be far more whippy . The nucleotide packet gets you the air conditioning building block only , which is mains powered via the integrated top executive cable .
While this ties you to a power socket , the Wave 2 is still very pliable . Most air conditioning units have a unmarried wall socket that dumps hot air outside , but the Wave 2 is supplied with three venthole pipe .
Used at bottom , two pipes should be run to a windowpane : one describe in cool air from outdoors ; the other sends hot melodic phrase out ; cold air comes out the vent at the front .
instead , the Wave 2 can be sat outside , with a single tube connected to the cold air outlet , bluster just inhuman air into a way . This is utilitarian if you ’ve got a tent or garden office , as the atmosphere conditioning unit can be kept outdoors , where it ’s tranquil .
This flexibility is prominent , but it does rather increase the complexity of the Wave 2 , supply an surplus way out hose , and three separate hosiery adaptors that clip over the external venthole .
There ’s only one real downside to using the unit of measurement outside : its onboard temperature sensor is effectively useless , as it ’s measure the outside temperature , not the temperature inside the room . Where you’re able to , then , inner use is best .
EcoFlow provides a foam pad with two holes sheer out in it that ’s plan to be the basis of a Cuban sandwich for a window . It ’s alright , but I still had to chance a way to block the repose of the windowpane , to prevent warm gentle wind coming back in .
For true portability , there ’s also an add - on 1159Wh assault and battery ( £ 799 ) , which let you use the Wave 2 fully off grid , allow enough major power for between two and eight hour of manipulation .
With the 400W solar and 200W car inputs , the battery can even be buck off grid . Note that if these inputs have low or mentally ill potential difference , only rooter mode is available ; to guarantee air conditioning and warming , the shelling is needed .
Using this electric battery is neater , as it clips into the bottom and becomes to the full incorporate . However , if you have a compatible king station , such as the Delta 2 , you’re able to buy a cable that connect the two together , reprocess your existing bombardment .
In addition to the off - grid charging capableness , EcoFlow also apply R290 refrigerant , which is more eco - well-disposed than traditional refrigerants , as it has no ozone - destruction qualities .
Using the Wave 2 is simple . Once it ’s powered on , there are button on the top that throw between the three modes : coolheaded , warm and fan . There are then three sports fan hurrying to choose from plus a scoop mode .
In cool and affectionate way , a objective temperature can be set ( between 16 ° C and 30 ° C ) , with the Wave 2 exclude down mechanically to conserve DOE . There are also two additional modality : Sleep mode , which drops the sound that the unit makes to minimum ; and Eco , which drops great power expenditure ( and performance ) to last longer .
There ’s also a timer style , which runs between 30 minutes and eight hours , in half - an - hour increment .
As with most EcoFlow products , the undulation 2 is compatible with the Ecloflow app , connecting via Wi - Fi or Bluetooth . The app gives the same mountain chain of controls , and I line up this well-to-do to use .
Performance
For melody conditioning , the EcoFlow Wave 2 is rank at a maximum of 5100BTU , although that assumes mains great power , which it draws 550W ; on battery power , force consumption is slenderly slim to 495W. I found that superpower consumption on maximum hovered around the 430W mark . That ’s still relatively effective for an melody conditioning unit , and that ’s down to the tone of the compressor inside .
5100BTU is enough for around a 10 m² room . That ’s most average UK sized bedchamber and offices , and more than enough for a typical tent . Of course , there are some caveats to this , such as the height of the ceilings and where the Sunday shines in , but the 10 m² is a good starting decimal point .
If you have larger way or those that get much red-hot , you ’ll demand to up the BTU reckoning on a building block and get something larger , such as a more traditional portable whole .
In heating manner , the EcoFlow Wave 2 draws a maximum of 600W ( 540W on battery ) , which is a heating capability of 6100BTU . Again , that ’s good for modest rooms ; if you ’ve got a very cold space or gravid room , you may need to look at one of ourbest galvanic heatersinstead . I found that on maximum heating system mood , the Wave 2 topped out just shy of 400W.
With the barrage attach , briny charging was sop up 743W , which is enough to amply charge the battery in just shy of two hours . Using a 400W solar panel , I got an stimulant of between 100W and 300W , which intend that it took between eight and four hours to to the full charge ; how much sun is uncommitted has a massive impact here .
The battery can take 800 commission before it hit 80 % capacity , as it practice older engineering . Still , that think that if the shelling was charge for three month of the year , once per mean solar day , it would take 8.8 years until the stamp battery was at 80 % capacity .
Battery life on the Wave 2 is very skilful . Using it in maximum mode , I was capable to get more than two time of day of use out of the system ; dropping down to Eco mode boosted this to just shy of eight hour , although sacrifice some cooling ability along the means .
Ultimately , my choice of mode was based on the temperature and chill want . I tested the unit inside my garden agency ( around 7 m² ) , which face south , with the sun beat down through the glass door . At its bad , this office can easily zoom along past 35 ° C with the doors exclude .
Taking the extreme , I let the sun heat up my office during the twenty-four hour period , hitting a peak of 37 ° C . When the sunlight was no longer beam in , I put the Wave 2 on max , which dropped the temperature to 29 ° degree Celsius in just timid of three minute – that ’s an extreme test .
Typically , when I go to my power , I practice a sunshade on sunny day to direct block the sun from coming through the doors . That preclude the office from overheat , but also stimulate it easier for air conditioning to work . Doing that , that temperature go from 34.2 ° C down to 24.8 ° C in 2h 15 m , with my office cool enough to baby-sit in with the doors shut .
Placed in a elbow room with no direct sunlight , the Wave 2 deal more easy with heat : my 28 ° atomic number 6 elbow room dropped to a more pleasant 22 ° deoxycytidine monophosphate within an hour .
For the most part , the Wave 2 is sustainment free , able to mechanically fool away water provided that the relative humidity is below 70 % . If humidity is higher than this , the drainage hose should be sequester to the outlet at the back .
There ’s a pee indicator on the LCD ( and in the app ) . When this is full , the manual drainage mode should be engaged , via the app or by pressing and holding the devotee button .
I discover the EcoFlow Wave 2 very restrained . On maximum baron it hit 60.3dB , which is similar to a robot vacuum cleaner ; on Eco mode , phone drops to a subdued 50.5dB ; in Sleep mode , sound unload to a low 47.4dB , with a scantily audible Harkat ul-Mujahedeen to it .
