The NEW Wave 2 Portable Air Conditioner Review 

I have both Wave2 with add'l battery and Wave1. I bought them for transportability as well as battery/solar options. So far, I am using both in my 1100 sq foot house in NW Montana. Low humidity and so far highest outside temp (last year and this summer to date) has been 96F. I have the Wave2 in my living room with a helper fan from living room to bedroom. These rooms are on west side of the house so are the hottest late afternoon. I am able to keep them below 72F on the warmest days. The Wave2 is considerably quieter than Wave1 so Wave 1 is in a room furthest from the bedroom .. a home office space used mostly by my pets. Again 70-72 on the warmest days. I use a hose duct wrap and I use exhaust hose only and intake from house vs outside. I have EcoFlow Pro 2000 and last year in testing was able to run Wave1 7.5 ish hours on the fully charged Pro. I have not tested Wave2 with battery.

That is a great review! I don't need one for myself. But you answered a lot of questions about the unit. It is a lot bigger than I thought it was going to be in real life. And yes, I agree about the marketing not being super honest about the hoses and so on for it to work properly. It does seem like a good unit though. For the right person. Thanks for doing this review!

excellent overview .. thanks! ❤ I had already ordered mine a few days ago.

Thanks for the demo and info, have a great day

I have used it sitting next to me, to get a cool draft to cool down while resting in the house. was able to run the unit long enough to cool down and not raise the temp of the room I was in. So yes, I have used it w/o the hoses connected and it works for my need. Sure the hoses can be used to work more as a whole room/space appliance.

Nice and detailed review, thanks. Definitely not stealthy with the air venting out the passenger window, but works.

Nice to see units like this being produced.

Very thorough. Much appreciated.

From what I've learned in other videos, the bottom hose in the back, (Fresh Air) circulates into the exhaust and never comes out the front. They are separate areas that do not meet.

Just ordered and can’t wait to receive it! I LOVE the window panel and is exactly what I’m looking for but for a Ram Promaster. Great video.

Ok so it does not come with the battery nor the 12volt plug or the solar plug or the window vent mount And the mount is made by another company and has to be fitted to a car hmmm and this is suppose to be an option . Sounds to me like a money pit.

I’d recommend the 12v mini slit unit. It doesn’t take up valuable real estate inside the vehicle, and I like the ecoflow line up of products.

Been waiting for this review

i tested in my Tiffin Cahaba 144 sprinter with curtain so cabin not cooling. Its 96 degrees in south florida today, you can run this 2.5hr on high but need your AC unit on - It wont work alone - having Coleman Mach 13,000 btu quickly lowers temp to 75. then use Ecoflow Wave 2 to help keep it cool. i also use montek 1000 and my battery is 540ah battleborn with xantrex.

Great video!

I think this ECO-Vent openings should have mosquite net and somekind of shutters to protect from the rain. Also it wouldn't look so "open" to outside luring someone to put trash into to pipes. Also this look screams you're inside, not so stealth solution.

Recently purchased a Wave 2 (w/battery) for the specific purpose of cooling a square-drop trailer (5x9), and a roof top tent mounted on top. A/C for night-time use while sleeping. Cobbled-together a Y fitting off of the cool air supply duct, and reduced down to two 3" collapsible hoses (vinyl exterior/ aluminized interior). One to trailer, one to tent. Wave 2 will be located outside, off of the ground, in the annex attached to the overhang of the roof top tent. Did a setup test in the driveway the other day, and seems to work okay. Real-time test in a few days during a 4-night stay at a Nat'l park. I own a few EcoFlow products, and their app is convenient to run all devices.

Great review thanks for the great

Thanks for showing a quick way to set this unit up in a sprinter. However you didn't share any info on the outside temp vs inside temp or how long it takes to lower the inside temp. Pretty much felt like an ecoflow commercial.

Great presentation. Two groups of questions come up: what are the temperatures in the fore and aft areas of the van assuming the AC is on the front seat; and how much water collects per hour or day of air conditioning, and is that water, potable.

Thanks for sharing! I'm torn between Wave 2 and Mark 2, and after watching your video, I think my rooftop tent would be better suited for Mark 2. It's also a compressor-based cooling system, but it's even more portable than Wave 2. The design allows me to easily lift it with one hand and place it in my rooftop tent.

First of all, thank you very much for this excellent review. With so many tips and knowledge I was able to make a decision. this was the best review I have seen so far. So my compliments and thanks. However, please, please, if you make a movie of 28 minutes, don't fill it up with this senseless, soulless, useless 'music'. It is frustrating for a musician to listen to it and it really hurts and tires my ears and brain. Sorry for this comment, but so many people do it these days, and it is really not necessary. Your video speaks for itself, and you made a quality video!

Awesome!

The short answer : yes The long answer : yes The key to success : massive battery bank, massive solar panel setup, parking in shade whenever possible, only require A/C for key intervals (aka 2 hours to fall asleep, then turn off)

Appreciate your reviews .. always professional. One question can I vent out my MaxxAir Fan vent … I have a front and rear MaxxAir and want to connect to the rear one to vent the two lines …

WOW!!! are you one of the pit crew on Talladega Nights The ballad of Ricky Bobby? Spitting image

Did you see it at 50 degrees or colder in a van that was in 100 degree heat? Did you notice that the temp was cooler on ac versus dc? Also does the fan turn off when it reaches set point? Or does it keep blowing and just turn off compressor?

Love the product but the price is just too much.

Maybe i missed it, is there a remote thermostat? Thinking of replacing the furnace in a small pop up tent camper with one of these. Then ducting the conditioned air into the sleeping area and with the curtains closed i would want the unit to cycle pn and off according to the temperature in the sleeping area.

I recommend some kind of mesh cover for the vents

we just took this trip. We pstarted Boothbay and stayed on R 1 all the way north with a stop in South Bristol for a visit. Lots of beautiful stops along the way to skolnik point. Sorry we didn’t plan longer.

If the unit was inside a tent or van why is the air inlet needed? Wouldn't it be better to cool/ recirculate the inside air rather than drawing hot outside air through the unit?

I've been thinking about snagging one of these during the anniversary sale and wanted to see what people may advice in my specific situation. This product is a no brainer camping in a minivan (Sienna) for cooler temperatures during the night in hotter climate (Texas etc). I understand the limitations of the product but would only need it to keep temperature comfortable overnight in the warmer months of the year. My plan would be to use the vans own AC to cool it before bedtime, and then run the Wave2 in eco mode to keep things at a comfortable level while sleeping. It looks like it's perfect for this. The ONE concern that I have is the battery and being able to use it more than one night without shore power.. I'm assuming it will drain most of the attached battery over night, and while I have 2 solar panels, it's only 230w (100 + 130). Will this even be close to enough to top up the battery for night 2 and onward or will the capacity just get smaller for each night ? lol? Is this a scenario that makes sense if I'd need to use it for several night out in the middle of nowhere? I do see that they sell the 800w alternator charger, so I guess that could be a way to recharge it while running the car for faster top up, but then you do have to run the car a long time... What say y'all?

Any window vent adapters for transit anywhere?

Great informative video. I’ve been using mine for a couple weeks. It’s pretty bulky I must say. My biggest dislike is the hoses should be insulated. When set up inside, the exhaust hose gets very hot and heats up the air while the AC is trying to cool. This offsets the units cooling power. I’m also thinking the unit should use the fresh air hose to suck in the newly conditioned air from inside rather than outside. I’ve noticed when the compressor shuts down it pulls in humid air from outside raising the humidity inside. But I really think the hoses should be insulated. I like the unit, but I’d say it just isn’t practical for hot and humid locations. But that’s only my opinion. I’d like to hear others opinions.

Seems to me you could put this in a cabinet for it to live, with ports in the side or floor. If your trip didnt require AC, you could plug the holes and get more storage space.

Terra wagen should make one that fits inside the maxxair vent opening to vent out the maxxair fan

Would I be able to use this with my Eco Flow River Pro?

Whenever I am considering a heating or cooling option, I always check the temp of the air coming out being used to cool or heat the space. If that temp isnt at least 15-20 degrees cooler or at least 30 degrees hotter than the air going in it probably wont cool or heat properly. I probably wouldn’t use the heat pump function. If it actually cools well for a van sized build, it does look like a good solution. 5,000 btus could work if one’s insulation is right…even in warmer areas. You dont want to oversize your ac for your space either. It seems like a decent way to try…i like that it can have its own panels powering it directly….and it only takes 400 watts. I wonder how it compares to the energy usage of typical units.

To save energy,I would recommend using this w another heating source such as large white candles some spacers and a terra cotta pot. This could be done when awake,and the candle can be extinguished just before sleep, lit again in the morning if necessary.While the heater would provide more instant heat,the candle could be used to provide more longterm heat.Candles made w Crisco shortening in tempered glass can last for days.Just melt the Crisco enough to scoop some out into the candles,pack it down slightly,but not too tight,and then run a small single white candle down into the middle,making sure it reaches the bottom. It's that simple,and perfect for pairing w this device in rotation to save energy.

Neat idea, but like portable ACs that people attempt to use for houses these are super inefficient. I get why they made a 'portable' one but I wish someone would release a 'tiny' mini-split for ~252 cubic feet (not sq ft which is the common rating people use, which is bad imo). It would be ideal to be a roof or wall mountable so people would have options. I could see that selling like hotcakes for van life people who need/want both. Hearing '10k to 14k' BTU for our small spaces is just crazy, is a well insulated van still that bad when compared to a home?

Can the drain be connected full time ?

I seen in the video that you need the factory battery attachment but didn’t see if my question was addressed. Can this be wired into an existing 12v battery bank Victron power system to power it off your battery bank?

What state do you live in and did you find it cooled the van enough? I see people on FB groups state they returned it etc. I wonder if the people who don't have success just dont vent the system anywhere. THoughts?

I had the WAVE in 92 degree humid weather last year. I used the dual vents, venting outside the passenger side. I was so miserably hot all night, I left the next morning at daybreak. It didn't cool the van to any comfortable degree. . Any ideas why? I am wondering if I should not of sealed off the vent hole that pulls in the air, and had the inside air recirculed instead. I regret buying this unit. BTW, I plugged into 110.

I just returned my unit for a new one. Mine did more than just leak a bit. After running it and draining it through the hose i would still get significantly leakege as soon as i moved it. Is that what you experienced???

It seems like a good unit, but all the hoses would prevent me from using it in my van. I would prefer the roof mounted AC

You totally glossed over or misunderstood how the “conditioned” side works. If placed outside a tent as you describe. It’s efficiency is lowered drastically as it would also suck outside air through the front lower grill to condition and pump it into the tent. This makes the unit work much less efficiently, using warm humid air all the time to then cool. Placing the unit inside the tent or any enclosed environment would let it use potentially already cooled and drier air to then further extract heat from said air. This would compound its efficiency.

So I’m a fan of ecoflow, but in a van life environment where real estate is at a premium this ac unit takes up to much of it. A better option for this situation is a mini split for RVs.

Ecoflow just needs to turn this to a roof mounted unit. Is there unit that can do this currently in the market?

That air conditioner is huge

How many amps does it draw on full?

how long are the exhaust tubes

How long do you think it would take to fully charge the add on battery from the car port?

How is there not a way to charge the extra battery pack without it being on the unit? There should be a way to plug the extra battery pack into a regular socket so you can swap batteries out if using it without solar.

Shame about the NMH Battery. I'd get a Delta to power it. Same price here in Europe.

Can I use this on my boat

You should have a tray to catch any water drip.

I am looking for pictures or video's from others who has installed it in a 159 ext Ram Promaster!!!..

Why would you need the additional cost of the Eco flow cable to connect when it already connects via 110 outlet?

How has this been working out for you after testing for a few months?

Great review but that underlying music track was annoying as hell.

higher BTUs also mean higher power consumption

Air con with no room in your van or heat with space and some food ??

It has impressive features. But wave2 has to be connected to the battery when charging, and it weighs 50lb. It's too heavy to take off the truck. I'd probably go with the cheaper, lighter weight zero breeze given the portability.

Does it need to vent if you're just using it as a heater?

5,100 BTU cooling capacity is plenty for a van, I have the Wave 2 and it will freeze you out. And heating capacity is plenty. I live in Southern Nevada and it gets hot down here in the Mohave desert. There is a such thing as over cooling and heating.. I think you need to focus on the portability, sure you can buy and mount a rood top A/C, but that is NOT going to run off batter or solar power. You did a good review of the unit but I don't believe you used it in a van.

Cold air out…? Since when do you have to vent a heated cabin?

This thing is heavy and big which makes it so uneasy to move around for putting in a wedged camper like GFC, super pacific and rooftop tents in general. Besides, the unit comes with only two vent hoses when it has three vent hose adapters. So far I felt regret to bought this AC unit 8:17 along with adapter battery. Please consider and carefully evaluation for your targeting of use before click buy button. Total weight of two units attaching together is around 50lbs.

Wouldn't that vent be inefficient by bringing in hot exhaust air into the intake?

Somebody please make this unit with a 12v high current input.

$2200 just for the ac is a lot.

still think this works better with only the heat duct attached

How about zero breeze, I'm torn between the two. I don't care much about the heating function, weight, size, and cooling capacity are more important to me, zero breeze would be much lighter, but ecoflow cooling capacity would be higher.

I liked the Ecoflow power kit until I learned that the batteries are assembled in china. They're not the best for making quality products so I will stay with Lithionics. Most cells are made in china but there are some brands of batteries made here. Lithionics and Battleborn. Lithionics are built better and are safer. I'm not sure yet if Victron batteries contain cobalt but that will never be in my van.

They really want you to use their battery, should have disclosed the 48v dc input which supposedly can only be used with their other battery systems, pretty sure you can work around that without their approval, of course! Not a good way to do business in my book.

This is product how price

As per the manual: "If the product is tilted (for over 10 minutes) or impacted by a strong external force, immediately turn the power off and remove the power cord. Leave it to stand for at least 2 hours before using." In the context of a campervan or RV, isn't that a somewhat disqualifying constraint? if you drive all day, the unit will likely be subjected to a lot of tilting and motion. So whenever your reach camp, you'll have to wait for 2 hours before cranking up the cooling system?

5000 btu in a box. Same thing

this video may be true on the West Coast, but it is not true out east. I have a very similar set up in Tennessee and it can’t handle the humidity. Once the temperatures reach high 80s , my wave 2 at full blast can only maintain the outside temperature inside my van. My van is fully insulated.

Pretty much not worth it for a van...

It’s expensive, it’s a hassle to set up, looks like it takes too long to set up, those vented hose’s look unsightly. If they weather proofed it and you just had a single hose pumping cool air into the van through the window would be a better far better solution in my opinion. The noise generated from the unit would be on outside.

Overpriced.

Appreciate your reviews .. always professional. One question can I vent out my MaxxAir Fan vent … I have a front and rear MaxxAir and want to connect to the rear one to vent the two lines …
