EcoFlow Wave 2 - Actual Runtime Testing and True Performance!? The First Portable AC & Heater!

[@greengooseman]

I bought a cheap pair of mens XXL sweat pants from Walmart. I inserted the exhaust hose into one leg of the sweatpants, across the hip section and out the other leg. made a great insulative sleeve.

Great video Jason. You have by far the best data on the Wave 2's performance and runtimes. Worth the wait!

Thanks, Todd! Your review video covers some excellent points as well. I loved your camper van experiment! These are pretty useful devices.

[@rnrider1978]

Jason, nice review, where did you get that piece or what is that piece called (the one that goes between the window) to intake and exhaust the air please?

@@rnrider1978 I built it myself out of a 4x8 foot of insulation foam from home depot.

[@revfatman]

I have to say that this was one of the most in-depth reviews that I have seen of the Wave 2. I applaud you on your hard work. I do wish that you had done the test that you alluded to - placing the Wave 2 inside the truck camper and exhausting it as you did inside your house. That is the way this thing was designed to be used and it HAS to make a big difference because you would be recirculating the already cooled air instead of constantly introducing and having to heat the 100+ degree air from outside. Every reviewer I have watched has made this same mistake, and I really would like to know what the difference would actually be. Thank you for being the first one to actually acknowledging the fact that it could have been done that way at least. It would be awesome if you could run the test that way and do a Short on the results. BTW I am not intending to come off rude or negative, I was just really excited at your level of testing and was hoping someone had finally given me the info I have been looking for! Thanks for the diligence of your reviews!

[@Jasonoid]

I'll think about making a custom tailgate insert for the truck to test that out. I agree that it would be more effective to have the unit inside the truck and expelling out hot air.

[@marvinsauer8493]

Very informative video, thank you! One change I would make with your install. Instead of putting the intake and exhaust that close together, keep your vent tubes straight. IE, place the exhaust high enough in the window opening to straighten out the tube. Hot exhaust air will flow much better if you don’t change direction with that big drop section, AND natural flow is for heat to rise, don’t try to change that. The other change would be to actually wrap BOTH intake and exhaust tubes with insulation. Both ducts are carrying air warmer than indoor air. Flexible insulated duct or just wrap in batts with a protective cover will make a very decent difference. When the duct in completely “invisible” to you thermal camera (IE surface is room temp) you have the correct amount of insulation.

[@Jasonoid]

The exhaust air comes out with quite a bit of speed so I don't think the drop affects it too much but I do agree wrapping both in insulation will be beneficial, especially in the winter when I am bringing in frigid air from outside! Thanks for sharing your thoughts, much appreciated!

[@marvinsauer8493]

@@Jasonoid part of the reason to separate the condenser inlet and outlet is to prevent crossover air. The manufacture built it with wide separation for that purpose. The exhaust really should be as far away from the condenser intake as reasonably possible. About 40% of the power used by the USA is just to move air. It isn’t cheap or energy efficient. To keep the consumption down the fans are engineered to ”just barely” move proper amount of air. So any restriction isn’t desirable. Those 12v fans do not have the ability to generate much static. I promise you that “kink” in the exhaust is reducing capacity. Change the tubes as I described and then check your tube temps with your thermal, you will see a change. That is reason your truck install was lacking. Once again reducing airflow through the evaporator caused the evaporator to ice, thus reducing air flow and cooling over time, as you observed. Also the unit MUST cool recirculating air, never single pass outside air. Physics forces the removal of the latent heat, BEFORE it can remove sensible heat. With single pass air it doesn’t get a chance to remove latent heat. Recirculating air will allow it to slowly remove latent heat (one time) and then the unit is just removing sensible heat.

[@ArtJourneyUK]

​@@marvinsauer8493Thank you for a great explanation, I was wondering why there was two inlets for air and your explanation answers that.

[@caver6292]

Works well enough, achieved 15 degree difference (which felt cool inside the square drop trailer-in the shade, the lowered humidity helped a lot too) in 95F and 80% humidity weather here in Florida. I was also running two small USB powered fans to circulate the cooler air. My main complain is not being able to mechanically/manually set the unit to external drainage. Every time the unit shuts down the drainage is reset to internal, which in turn shuts down the unit when really full, which happens a heck of a LOT here in Florida. The hoses, being proprietary sizes are also a PITA to hook up to anything commonly used in small trailers. The Wave 2 was outside the small square drop due to space issues, I also wish the company made a raincoat for the unit.....

[@davidputt4638]

Makes sense that it wasn't able to work quite as well in the truck. It's the same as turning off recirculating air in a car's AC when it's hot. It has to start from scratch instead of recirculating pre-cooled air and making it more cool.

[@adlerz5433]

I don’t know if you touch on this in the video but the dual hose design and heat exchanger is really unique and prevents negative pressure in a room this is rlly important for efficiency

[@worldcomicsreview354]

I did some one-hour testing with one of these. Off the top of my head (and in the height of Japanese summer, I'm on the top floor with a flat roof too, brutal) my installed mini-split used abot 0.75kwh, cooled the room in seconds and made the humidity much more comfortable in minutes. The Wave 2 plugged into AC used about 0.37kwh, and had basically zero effect on the room if you weren't sitting right in front of it. Nice ￥177,000 paperweight. I also had two t-shirts tightly wrapped around the exhaust pipe. The sides of the unit itself get pretty hot, and also the thing the exhause hose clips into doesn't seal well, so a lot of hot air was escaping from the sides. For reference, the room is a "6-mat" space with about 2m high ceilings, also a 4.5mat loft space and a further 6 mat area below this, but that's broken up with internal doors. I moved the ecoflow up into the attic space, and put the pipes out of the window up there. I got a second set of pipes and now have the cold air blowing along a long run and coming out, angled slightly downwards, into the main room. That works a lot better (though we've also had a slightly colder spell around a typhoon).

[@larrywong7834]

Use your .75khw mini split to cool the larger room. Making the room ambient air hit desired temp for like an hour. This also removes heat contained in the walls, ceiling, and flooring of the room. Everything now is temperature cold neutralized. Now turn off that .75kwh mini split. Then. Turn on the Wave 2 set at fan#2 or fan#3 at 60F to 71F. Power draw should be under 400w range. Use Solar panels to drive this needed 400w. You could pretty much run just off Solar for free now. Your PRE colded neutralized room temp likely can be maintained for hours. If needed switch W2 to MAX. Still running W2 free from Solar.

[@worldcomicsreview354]

@@larrywong7834 That's basically what I do now, only I don't have enough good solar up yet so I just plug it in, still using "half"(ish) the power!

[@mariokleidosty9175]

Thanks for the testing Jason, I just wonder why everybody calls this a heatpump while ignoring the fact that the temperature range in which it will work in heating mode is VERY limited. The Wave 2 will not operate in heating mode when the ambient temperature is below 5°C/41°F. This is something i consider a serious limitation for unit also sold for heating. Technically it's clear that they didn't want to worry about the evaporator freezing and having to include a defrost function but nonetheless it's something worth being mentioned!

[@Jasonoid]

Since it was super hot I didn't have the ability to test the heat pump side of things. I've never dealt with a heat pump before so we'll see how the experience goes. I will be sure to show how it goes as winter arrives.

Great explanation. Those hoses are pretty huge to work with.

[@Jasonoid]

They are large so they don't stop the airflow. They are similar to any other portable AC.

[@johntate5284]

Probably the main reason you weren't getting that much cooling in the truck cab, was that the cooling loop was compromised. When you were running the unit inside, the unit takes the room air in and then cools it, and is a closed loop. When you were running it outside you were running it in an open loop configuration and the pressure was no loner net zero. It would be like trying to run a refrigerator by just bringing in room air instead of recirculating the cool air inside. I have seen other people tackle the cab cover issue by building a plug that sits in place of the tailgate (just a bigger piece of foam with the same two holes, which retains the net zero pressure operation and leaves to cooling loop closed. Even with no cab cover insulation, a smaller unit was able to keep the truck bed much cooler, even in the desert. I am actually considering one of these for my car, as it is much cheaper than having the car AC unit repaired. Thanks for another great review!

[@Jasonoid]

Thanks John, I totally agree! I debated about building a custom tailgate from insulated foamboard and I still might. Overall this is an impressive unit. Lots of different use cases.

A really good test that I don't see anyone doing on KZbin is demonstrating how long the Wave2 can run in a car or van when it's been charged via the Ecflow 800.00 Adaptor where it get's it's power off the regular car battery, (there are so many people posting videos on KZbin about how they're suffering in the heat living in there cars, when they have a source of power for air conditioning in the form of there ICE vehicles, (with the ICE engine turned off) they just don't know how to convert that ICE Power to power the Ecoflow product lines of the adaptor and WAVE 2 , so at a minimum they probably can sleep at night more comfortably when it's over 90 degrees still in there car.

I have the unit and not sure how impressed I am with it yet. I don't like that you have to use Ecoflow battery banks for the DC option only. I wish you could use something else. Here is something for you to try, which I think would work. 1. If there could be a way to put a little bit of the cold air coming out into the intake to lower the intake air, that would lower the out cold air. I routed my tube from the cold coming out to the intake and that made the Wave 2 temperature drop significantly. 2. I wonder if it would cool better if you used the heating function, since the exhaust would be cold and you have more BTUs.

[@smol_yote]

11:35, you’ve created a thermal battery at that point. By cooling with excess power at noon you don’t need to use as much precious battery power in the evening to maintain the same temperature

[@spartanaerialservices]

I use this exact unit to cool a 15x30 single floor tiny home (cabin lol). It works perectly. I have the cabin insulated of course, however half the cabin does get full sun and has full sized windows. The wave 2 cools it to a comfy 75 degrees, so when it’s 95 out thats a huge difference. Waiting to see what the heat pump can do in the winter. (Home is powered off grid with Bluetti AC200Max, with twin B300 batteries, hooked to a breaker panel, house is wired 110v only). I run the wave2 off this system. We have 1000 watts of panels going in. Never short of juice!

[@tsk1979]

I see most people throw 2 hoses outside. But I guess you can only do the cold air exhaust hose outside , and let the intake air come from the room itself on the heat exchanger side. This means if you are warming the room, instead of pulling heat from the cooler outside air, you do a pull from the warmer inside air. Of course that does a suction effect, but most tents are not sealed. So should not be an issue

[@anthonym5395]

Excellent research Jason!! I use an EcoFlow Wave 2 connected to a Delta 2 Max with an additional D2 battery for 4096Wh (and a measly 320W solar but it holds its own), it works great. The weakest link in the entire setup is also the cheapest part - the exhaust hose! Your loss of energy through its thin plastic is insane. I'm sure a towel can help reduce that loss but I use an insulated 6 inch exhaust hose from Amazon. I haven't run a thermal camera on it but if I had to guess it's well below 100 degrees even after being used for hours.

Cooling your vehicle with the machine outside in the heat plus the cool air has to pass through the warm tube before it gets to the car window plus the narrow gap outlet into the car, these 3 factors that's why it wasn't cooling down the cab properly

[@dionwatters992]

You can buy insulated flex duct and slide it over your hoses to completely block most of the heat transfer from the ducts. also, the reason you got such poor results on your truck was because you had the unit outside, and it was having to heat the outside air as it pulled it into the front evap coil and try to cool it. I bet the air duct temp wasn't as cold as it was when you had it indoors.

[@MikeNewham]

Best review on Wave 2 this far.. I wonder if you could just splice the XT 150 cable and with an appropriate fuse just connect straight to a camper battery bus bars ?? Save on buying the battery.

[@Jasonoid]

It's all proprietary and runs off 48v. You could connect a 48v volt battery into the solar charging port and it would charge quickly.

[@jaroslavskerik6303]

I assume since the inlet of the suction hose is so close to the outlet (hot) hose, there will be a "short circulation". The hot air from the outlet hose discharge (near its outlet, overpressure is created) will be automatically drawn into the inlet hose (near its inlet, underpressure is created). This will obviously worsen the efficiency of the unit, as some of the heated air will be drawn back and air warmer than the outside temperature will be processed. This problem can be easily solved by delaying the output/input Thank you for the perfect video 👋

OK, I’m in Phoenix and live in a tiny house. Sounds like this machine would work, but our Summer days are over 110 degrees pretty regularly! Any input would be great, as power went out last Summer. I’m also 70 and my 78 year old sister lives with me. Thank you!

So whatever room you're in, it only drops the temp like max 5 to 6 degrees for about a couple hours then u gotta recharge for 3 to 4 hours. Then it'll run for another couple hours, lower the temp a few degrees, then recharge it again for few hours.. 1,200 bucks to get that results... Damn man idk. 😬 People are wanting results that are closer to an actual window unit. Doesn't have to be EXACTLY like a window unit, but a hell of alot closer than these results especially at that price range. Can run an actual window unit off that eco flow delta 2 for that hour and a half and get better numbers. Per manufacturer, the 2 solar panels recharge the station in 3 hours and then u can turn the actual window ac unit back on for a couple hours. Seems better results than this 😬🔥

I run this on AC power all the time. You can run this by plugging into a wall just fine. It won't run off just solar alone or a 12v battery. The only DC input it will run on is a Ecoflow power station or smart battery xt150 cable.

I wonder if the device would be any more efficient if you had some more separation between the two hoses. I imagine as close as they are a fair bit of your outtake air is going right back in the intake. It's an interesting device. At the current price I can't personally justify it but I like the idea. I think it'd be neat if you hooked it up to a central AC return duct and turned on fan mode to see if it could do anything to the whole house when you are running it full power. I am still moving stuff over to solar and right now I have a situation where my batteries are full, I run the PTAC in my office full power and I am freezing, but the rest of my house isn't benefiting, and I need a way to push the excess cold into the house. Right now, I have a fan on an AC duct trying to push air through it backwards.

[@Jasonoid]

The exhaust was on the top and it has quite of bit of velocity flowing out, I doubt the hot air was being sucked back in. When I measured the intake air temp, it was the same as the ambient outdoor temp

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...

To be quite honest, I would prefer buying a portable window unit a/c at one-third the cost. This ecoflow unit does not sound like a game changer. It also appears that it does not significantly reduce ambient temperature like a portable window unit on wheels would. I know a portable window unit may be bulkier and heavier, but I'm sure it would make it cooler inside. Well worth the inconvenience while going easy on the wallet.

[@Jasonoid]

It's definitely built more for a portable setup and I wasn't really using it that way in the video. This works just like a 5000btu window AC unit but it's also a heat pump. That's where the added cost comes from. I haven't ever seen a window heat pump before. Maybe a different brand will come out with something like that soon? I'm looking forward to testing this as a heater this winter as well.

[@jcadag8789]

Hi! Using AC power while in eco mode will it consume lower than 238 Watts or it just stay that way until it reach the set temp then the compressor is turning slow consuming lower amount of power like those small 1 hp split type full inverter air conditioner?

[@TechNep]

Can you use the wave 2 battery and delta 2 in combination?

[@Jasonoid]

You can only use one battery at a time.

[@CC-gt3ro]

Does the wave 2 solar input or ac input , charge the delta 2 max in addition of the 1000w pv1 and pv2 ? So technically Does the wave 2 add an additional pv3 (limited to 400w) for a total of 1400w solar input And simultaneously discharged the battery for the wave 2 load? I doubt but it would be nice. Can the wave 2 be plug on only a delta 2 max extra battery without the delta 2 max and act as a battery charger with solar /Ac input ?

[@Thergood]

Can this be powered via DC without an EcoFlow portable battery or Wave 2 expansion battery? Can it run off a mobile 12v DC system or a 12v 30a output from another brand powerstation? I love the unit, but I already have plenty of battery capacity in other systems, I don't want to have to pay for an EcoFlow battery just to run this unit.

[@sawyerwaterman5846]

My guy thank you

[@arachnidkalven]

Would really like to know if it works with only the delta 2 external battery?

[@NoZenith]

Came back to watch this again because I am trying to budget some large purchases for next year's camping and this winter backup power... I'm seriously looking at the Delta 2 Max and the Wave 2 and skip the Wave 2 battery with all of its ridiculous limitations like having to be plugged in to charge and not having any way to really use the power other than a USB port, so it's not even a good backup battery to run a refrigerator or anyting, along with its much lower charging input capacity. Just putting that money into a Delta 2 seems smarter but the Delta 2 Max gives a lot more functionality

[@Jasonoid]

Going with the Delta 2 would give you similar run-times but much more functionality since it's a full power station.

[@NoZenith]

@Jasonoid I'm glad you agree with that thought. I think your review of the max makes me lean that way for the additional investment, because it gets you 2 solar input ports so you can plug in to the car and a solar panel to get more juice on cloudy days and the increased capacity gives a bit of buffer to make sure you're not fully discharging the battery for added longevity. It would probably last me for a good decade and be a really good option for a few days of no power to run my house fridge

[@gerryperia7871]

Can we use this ecoflow in Hawaii, Jakarta, Vietnam, or the PHilippines? Does it carry 220 Volts and 50 and 60 h? Can you shipped this overseas like Vietnam or PHilippines?

[@hardtruth2039]

Can you charge via solar thru the wave2 and the delta 2 or a delta pro at the same time?

[@mike810133]

thank you for this useful video, i got Delta 2, it takes 1.5 hrs for full 100% charge. when run out the Wave 2 battery, how long it takes 100% charging time?

[@markkenton4945]

Will the Ecoflow Max 2000 power the Wave II via smart battery DC port?

[@chrisreynolds6331]

Looks like a great unit. I wonder do you have to use their own battery or can you use any lifepo4 battery?

[@Jasonoid]

To run off DC power it need to be their power station or battery (using the xt150 port). If you want to run it off a larger LFP battery / inverter / solar setup it uses a little more power (since it's AC) but it still works great that way too! For example I run this off my AC500 inverter / solar everyday through my transfer switch and its been great.

[@ElladanKenet]

Good video. Glad I watched it. For my own purposes, I don't think I will need the Wave 2 right now, and your video helped me make that decision. But I am glad this exists!

[@Jasonoid]

That's exactly why I did the video. Thanks for sharing your feedback.

[@savagedan100]

But how well does it heat

[@JimMcPartland]

Great video! So this will only work with ecoflow?? DC wise

[@Jasonoid]

It runs just fine off AC power (which will work with any power station or inverter setup) but running it off DC input, it only works on Ecoflow power stations and batteries with the xt150 cable.

[@mmunoz5875]

Great video. I wanted to ask if this will work with no issues using a 200w solar panel setup? I'm currently using 2 Renogy solar panels (200 watt) with a Renogy Rover 40 Amp 12V/24V DC input MPPT solar charger and a Renogy 2000W Pure Sine Wave Inverter 12VDC to 120V AC Converter? I also have a LifePo4 Battery 100Ah 12V 1280Wh Deep Cycle Lithium Iron Phosphate battery. With this setup the only thing I have plugged into the inverter in my camping fridge.

[@tedfort1698]

That system wouldn't be nearly enough to run it consistently. You'd likely need 600W of solar and probably 400aH of battery.

[@larrywong7834]

I have D2M attached to W2 via xt150 efficient dc current. D2M PV2 solar feed is 3 x 220w panels serial array. PV1 is 2 x 220w bificial serial array. I run my W2 8am to 8pm. Couple hours at MAX. Rest tends to be Fan at level#2 or level#3. Temp set to 71 mostly. At 8pm my D2M state of charge is 60%. I power off the W2 near this time. At 8am my D2M state of charge is about 56%. Everyday I do not need to attach AC power supply to the D2M. Air Condition mode is always on via Solar Power or D2M battery. My W2 only has the 5 inch Exhaust hose connected to Outside Patio. 6 inch hose not connected. Air In is from Living room ambient air. 5 inch hose is completely Insulated. Very very Important to do this. Patio in shade been 110F to 118F degrees.

[@larrywong7834]

At 8am my D2M state of charge is about 56%. During the morning with W2 air Condition on my SOC drains to about 20%. But Solar brings SOC back up to 98-99% in the afternoon. Which often holds at this level till about 5:30pm. As the Sun goes down my SOC drops to about 60% near 8pm. Yes. For a couple hours my W2 air condition uses D2M Battery quite a bit.

[@larrywong7834]

Often my D2M display shows 500w Solar Input from just the 3x220w Serial Array when the Sun is very bright. Just one array's solar feed.

[@larrywong7834]

Jason. Thank you so very much for your EXCELLENT Video. I've learned so much.

[@larrywong7834]

Interesting Results receint. As Hurricane Hilary to approach Central California tomorrow on Sunday. My D2M dIsplay shows PV1 Solar 401w. at 2 x 220w bificial panels serial array. PV2 Solar 502w at 3 x 220w panels serial array. THUS 900w inputs my D2M to feed my Ecoflow Wave2 in AirConditioner mode

[@Jasonoid]

Thanks for sharing your deep knowledge and experience about the Wave 2, much appreciated! Thank you for also answering other viewers questions!

[@latymz]

It’s clever but more than anything it’s efficient. I think I’ll just grab a back up window unit. I like it but it’s performance seems quite mediocre.

[@c.y.997]

Good video. Using the styrofoam for the window is a great idea!

[@Jasonoid]

Thanks!

[@coryo617]

Will this work with ecoflow delta 1 ?

[@johnowens8530]

Do you know if I can buy this with the add on battery, and carry a 200 ah battery with a connected 12 volt socket, and charge the add on battery directly through that socket with the car charging cable, or do I need to regulate the power coming out of the 200 ah battery? Excellent review thanks once again!

[@Jasonoid]

That's definitely possible. It will charge around 90 watts with 12v directly, you'll want to boost up the voltage to 36v to allow for faster charging. I have a bunch of videos talking about that principle.

[@shanes481]

I wonder how much the heat coming off the hoses offsets the actual cooling output? With a window unit the heat is outside of the house at all times. After factors like that are considered I wonder what's the actual cooling btu's.

[@Jasonoid]

I cover it with a towel when I use it, another comment or said he found an insulated hose that fits this as well. In stock form you have a 130F plastic tube chilling in your living space!

[@arzhangsadeghi]

Hi, thank you for your video, quick question: In the winter the air intake part which is outside towards the cold environment will get frosted and will covered with ice , how could it still suck the air inside then ? even if it is connected to outside through the duct I'm pretty sure in cold winter it will still get covered with ice and frost. my question is , can it still operate in that situation or no ?

[@Jasonoid]

I haven't tested the heater mode much since it's been very hot. I'll be testing to see how this works as a heater soon.

[@fabiangerman6932]

Hey Jason Thanks for the video, got a question if wanna use the wave 2 just as AC for a room do I have to use the ducts? I just want to be sure about it before I install everything!

[@Jasonoid]

You'll need to exhaust the hot air out of the room somehow or it won't do any cooling. That works best using the ducts and a window.

[@Jim-xz1ew]

Don't throw a towel over the vent line. Buy a short piece of ac tube duct insulated line. Fit the exults tube threw the insulated ac duct. A little duct tape to seal the tube and your heat is gone. How is throwing a towel over of the vent line going to reduce the heat??

[@Jasonoid]

I showed the image of the 'before and after' using the towel. It dropped the exhaust tube temps down from 130F+ to 110F... but yes, an insulated tube would be best.

[@iamkeebz]

Is there a condensation drip tube? Where does it dump the condensation it collects?

[@Jasonoid]

It does have a condensation tube, it pumps out through a pump. I just have it sitting in a bucket.

[@etc-and-more]

These twin tube a/c,heaters make no sense to me. For a/c you are sucking in hot air and cooling it down rather than taking the already cooled air from the room which needs less energy to cool. Even worse for the heating where the mechanism is taking very cold air from outside and trying to warm it up rather than taking the already semi-warm air directly from the room and warming that. I wrote "even worse" because I doubt this heat pump will warm up any air if it is trying to process outside air that is under 45 degrees F. In my test of the Whynter heat pump a/c and heater combo, not having a second hose worked great in a 250 sq ft room with lots of windows that is attached to a large warehouse in the middle of the winter with temps in the 20's. This is a situation where your setup would fail, might have been nice to mention that. Also would have been nice to see your home charts go across a full 24 hours with another chart line showing outdoor temperature. Decent review, with a bunch of missing data/discussion but at least you provided the wattage.

[@ralph4e]

Jason where did you find the solar/cigarette lighter connector?

[@Jasonoid]

The Wave 2 comes with a 12v charging cable, a solar charging cable, and also an AC power cable.

[@jcw945]

Cooling is one thing...but heating, it will not work below 5C/40F in fact heating performance is impaired below 10C. Very disappointing as this had great potential for van life but it will not do what it needs to do.

[@billbradley2480]

With my wave2 I only vent one tube outside. It vents hot air out in AC mode and cool air out in heat mode.

[@Jasonoid]

That still works well.

[@ThomasDoerrArchitect]

Based on your analysis, I like it but would not buy it since it is dependent on AC or Ecoflow's proprietary batteries.

[@Jasonoid]

Valid point, I'd definitely recommend finding an option with a dual hose since I feel it makes a big difference in performance.
