A few months in the past, EcoFlow introduced its Wave 2 moveable air conditioner with warmth pump. The corporate appears to essentially recognize our critiques, so the staff despatched me this one early, earlier than it was introduced. However, sadly, one problem led to a different, and I stored not having a great likelihood to provide the HVAC unit a very good check. Certain, I may have fired it up hooked as much as a tent within the yard, however that doesn’t actually give readers a good suggestion of what the factor would actually do out within the area.
For readers who don’t need to learn the entire thing, right here’s a fast abstract: It’s a good moveable air conditioner that may serve in a wide range of roles each at residence and off-grid. However, there are two stuff you’ll want to consider when planning to make use of it.
Specs & Such
I attempt to not delve too deep into the weeds on specs when doing critiques, largely as a result of it might principally be a duplicate and paste type of job. You could find the total specs right here on the firm’s web site. However, I’ll cowl a couple of issues that I believe are an important.
The largest factor I seen in testing is that the Wave 2 is loads smaller than the unique Wave. It’s just a bit greater than half as tall, and weighs much less. This makes it a greater match for moveable use, and even at residence, it’s good to not have it take as a lot room. Like the unique Wave, the non-obligatory battery suits below the unit. The vents are on high of the unit, however they are often aimed ahead or extra upward as wanted, so no flexibility in the place you need the chilled or warmed air to go is misplaced.
Talking of warmed or chilled air, the unique Wave solely did cool air. The Wave 2 features a warmth pump function, so you can’t solely cool a tent off, however warmth it up! Dwelling within the Southwest, I haven’t had an opportunity to check the warmth pump function with out killing myself, however I’ll observe up on that within the fall.
One other function I discovered attention-grabbing was that it makes use of R290 propane refrigerant, which means it has loads much less potential for environmental hurt both as a result of the unit springs a leak later in its service life or on the finish of its serviceable life throughout disposal. Older refrigerants, like Freon (R-12) tended to be much more harmful for ozone and local weather change considerations.
Like the unique Wave, it has full app connectivity, and it really works off-grid. You possibly can simply hook up with it through Bluetooth and management it. Or, you may all the time simply use the buttons and display on the unit itself, however who desires to get away from bed in a tent?
Lastly, like the unique Wave, it’s very versatile. It may be used with twin hoses, with a single hose (unit outdoors), with a foam board that routes hoses by way of a window, or simply open to the weather. Utilizing an insulated shelter and routing the incoming and outgoing condenser air by way of hoses is probably the most environment friendly setup, however you might do nearly nearly as good to only put the rear facet of the unit outdoors and zip a tent/shelter round it in a pinch. Or, if you happen to simply need some cool air to be blown on you for a bit, you may simply use it straight out of the field.
My Testing
Earlier than heading out, I unpacked and examined the unit briefly to ensure it labored correctly, however I didn’t be ok with doing that for a overview. So, I waited to get out into the woods and really depend upon it for consolation.
At my campsite, I put the Wave 2 inside my Shiftpod shelter. For these unfamiliar, Shiftpods are quick-setup insulated shelters which can be generally used at music festivals and different conditions the place individuals would “glamp.” One actually cool factor about them is that they’re pre-made to just accept hoses from heating and air con models, and the openings clamp down over the hoses to maintain air leakage to a minimal. Additionally they have one other drawstring gap beneath the HVAC holes for {an electrical} wire (both from the grid, a generator, and even photo voltaic panels).
Regardless of my Shiftpod being considerably massive (it’s not the Mini), the Wave 2 rapidly cooled the within of the tent down and made it comfy to sleep for so long as it ran. However (by way of no fault of EcoFlow), it will definitely stopped operating.
Which brings me to the one three issues to be careful for in my testing.
First, be sure to have sufficient energy in your explicit wants. Eco mode in all probability gained’t reduce it for the most popular climate, so the built-in battery’s marketed 8-hour runtime gained’t occur. For milder climate, although, that’s in all probability about proper. When you’ve got entry to grid energy, this isn’t an issue in any respect, however if you happen to’re attempting to warmth or cool a shelter or construction off-grid in poor circumstances, anticipate to make use of 500-600 watts constantly and plan your photo voltaic and battery accordingly.
On future journeys, I’m going to make use of my EV’s battery as a backup energy supply within the occasion my photo voltaic doesn’t sustain with demand. It didn’t assist that my campsite was in the midst of an surprising thermal inversion (temperatures had been hotter on the high of the mountain than the underside) and {that a} bunch of clouds got here by way of that weren’t within the forecast. So, it’s most positively my very own fault and never EcoFlow’s!
One other factor I’d advocate conserving in thoughts is that the unit isn’t designed to be tremendous rugged. It’s not made from glass or something, however don’t plan on simply throwing the unit at the back of a pickup and driving down a forest highway. Hoping for the most effective gained’t get you very far if you happen to don’t preserve it within the unique packaging or use the non-obligatory carry bag. Utilizing both of these choices offers you the additional benefit of getting a clear spot to retailer all the equipment, hoses, and different stuff you would possibly want on journeys.
Lastly, I discovered that the Shiftpod’s blackout materials did assist preserve the sunshine out throughout some daytime sleeping, however the hoses did find yourself letting in some mild. This was simply solved by protecting the hoses with a towel.
All in all, regardless of these minor points, I had an awesome expertise taking the EcoFlow Wave 2 on my off-grid journey. If you happen to get one, and be taught from my expertise forward of time, you’ll have a wonderful expertise identical to I’m going to on future journeys.
