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.

I don't think that will insulate the heat very well

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

[@Jasonoid]

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?

[@Jasonoid]

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

[@atnfn]

No testing if it can actually heat up a room though, nobody seems to test that for some reason. Probably means it's worthless at heating anything.

[@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.

[@BigStipowski]

​@@marvinsauer8493 so sounds you use it without hoses and just place it in a room.. Ecob says you can do that.. that make most sense to me as per your statement about one time passing air vs multiple passes.. But I dunno.. Thanks for the input.

Great video, just what i've been waiting for. See what run times are on the delta 2 max, and delta two.

[@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.....

[@totenfreight2362]

Thank you for the review. Actual battery run times is what I was after

After having it since beginning of summer. I'm real glad I have the extra battery. Having that opens sooooo many possibilities.

[@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.

[@scadaiot]

Best review I ever seen for Wave2. Very informative.

[@Mike_219]

Awesome video Jason. Really like the explanation of how the unit works as it wasn't clear to me before. The Wave 2 looks like a pretty feasible unit depending on living space.

[@Jasonoid]

Glad it was helpful!

[@RedBatteryHead]

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.

[@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.

I have a tear drop camper that I would like to cool down at night for sleeping comfort. The inside dimensions are 5x4x8 feet so not that big of space to cool and the camper does have some insulation. My biggest concern is recharging the battery system during the day just using the vehicles 12 volt system as I drive. I have room for solar panels on roof of camper however cannot always rely on the sun. Which battery system would you recommend and what would be the best way to charge this as I travel down the road? Thanks

[@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.

[@markkenton4945]

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

[@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.

Great video and very informative! In the truck test, I think setting the machine outside the truck was a unique test. However, it seemed like a very ineffective way about doing it. With it setting outside the truck, it's constantly cooling hot air. instead of recycling already cooler air. With fresh hot air, it becomes a snowball effect and much less efficient. Also the thermal camera was super cool!!!

[@ScrapKing73]

There are more than three modes, there are six. From lightest to strongest you have: Sleep, Eco, Normal 1, Normal 2, Normal 3, and Max.

[@ScrapKing73]

I'm also not sure that it does any additional heating/cooling in the strongest modes. For escape, in hearing more the exhaust temperature drops again and again as you increase the modes, which to me suggests increased air flow but the same amount of heat transfer. I think it's only increasing the fan speed, not the amount of heat transfer.

[@ScrapKing73]

The manual mentions that it's only cooling half the time in Eco, alternating between fan and cooling. But that's specific only to cooling, in heating mode it tries to heat all the time in Eco.

[@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

[@ZoeyR86]

i feel you miss the point. this unit was never made to cool a room in a house it's really targeted at overlanders, van life, bed campers and insulated tents, I have the wave 2 and a insulated 9ft ice fishing tent (X500 CLAM)but live in indo California, i can keep that tent at 72 f in eco mode while it's 110f outside

[@Steve-ph4ec]

For your AC DC average power usage comparison, I’m curious if the in/out hoses were connected to exhaust compressor heat? Reviewer “Misprounced Adventurers” on Sept 10, 2023 found similar AC vs DC power use in contrast to your finding differences. Could be useful to also track humidity vs time, using a similar Govee device.

[@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?

[@user--PM]

i have watched several videos on this unit, thanks for your more indepth coverage. i think if i had purchased this unit i would have passed on the nmc battery and use a power station with the lfp battery instead. hope that you can make good use out of that unit, or find it a good home.

[@foodforestretirement2799]

I just purchased the Wave 2 with the battery and a Delta 2 max to run enough solar to cover the wattage during most of the day. I am going to supplement my central air in my living room with the Wave 2 because I spend 95% of my time in there. I will adjust my main thermostat more conservatively and see how it goes 😅

[@Jasonoid]

Sounds like a good plan. That's how I use mine!

[@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!

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.

How does the unit deal with water condensate. I know they inject it into the exhaust. I have a dual tube stand alone unit from a different vendor. But on really damp days in heat mode or really damp days in cool mode the unit can condense more water than can be exhausted? How did the EcoFlow engineers solve this?

Great video, as usual!! The killer for me with this, attractive as it is, is that if you don't already own one of their large power stations, you MUST buy the battery if you want to use the cooling function.

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'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?

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.

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 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.

I had a question. Can you have the wave 2 plugged into a delta pro AND have solar hooked up to the wave 2 as well? Or have the wave 2 plugged into a wall socket (or Delta pro) and solar plugged into the wave 2 at the same time? Thanks Jason! Hope I made sense. Basically I have a dedicated 1800 watt solar array to my delta pro and don't want to disturb the setup lol

[@Jasonoid]

I don't think it will cause any damage to test that out, having solar and AC power connected at the same time. You'd want to watch the power draw from the Delta Pro screen and see if the draw goes down once solar is connected. If I remember correctly it won't run directly off solar and needs to have a separate battery attached for that to function.

[@jaysonstebbins2539]

@Jasonoid makes sense . Thanks jason!

[@arachnidkalven]

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

[@bobysize]

Very informative video Jason. After watching this video i really want to install the xt60 on my diy solar battery box to get better run time on my ecoflow wave 2. Since the highest wattage on DC is 460w that mean i need the xt60 plug to handle about 40 amp, thats alot for xt60? Or there is a better amp xt60 plug on market? Thanks Jason.

[@Jasonoid]

Check out XT90 connections, they are rated for higher amps than XT60

[@bobysize]

@@Jasonoid thanks Jason

[@micklaws5520]

Heat pumps do not work well below 40 degrees F. Is there a workaround for this unit to work in cold temps?😊

[@Jasonoid]

Not that I am aware of. I'd mostly recommend it for the air conditioning aspect. The perk of heating is only useful on those more mild winter days.

[@micklaws5520]

@@Jasonoid That’s what I thought but was not exactly sure. Thanks much for info

[@toejamr1]

Can I use a home made solar generator like has been made on this channel in the past and run dc to the wave 2 or do we have to have the special plug that ecoflow uses?

[@Jasonoid]

If you run it off the AC inverter, yes. If you want to run it on DC power, you'll need to run it off a Ecoflow power station or smart battery

[@hardtruth2039]

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

[@shelley131]

I run a window unit 5000 btu in a gazelle gazebo deluxe and with this Texas heat it struggles. But at night it is cooler than the ambient temp allowing you to sleep comfortable for a few hours. Problem with the window unit is that they don't have the exhaust hoses so you must capture all the water it produces in a plastic storage container. Does the wave produce water like regular window units? Thank you for your hard work on your videos. One more thing I have two Delta max's not the Delta 2's, will it work with the wave.

[@Jasonoid]

This will work with any Delta power station, gen 1 or gen 2. It has a feature to evaporate the condensate water if the humidity is low enough while in AC mode. Since I live in a desert I haven't had to use the water drain and it evaporated it through the exhaust. If you live in a humid place, it has a drain that pumps into a bucket of your choice. (heater mode always requires a bucket).

[@m5research915]

@@Jasonoid Is it an actual pump? Can it pump the water outside?

[@_Sho_oK]

Pretty informative video with actual testing data and graphs

[@mas921]

since the delta 2 max has 2 xt150's; is it possible to connect the wave 2 battery to the delta 2 max, and then connect the wave 2 ac to the 2nd port? in this manner, it run for 18 hours potentially as per your testing of course, it would ve been much better if the wave 2 ac itself had 2*xt150 ports, one for the battery below it and one for a delta solar gen.

[@Jasonoid]

Yes, all expansion batteries are able to connect with each other and add run times.

[@garynelson1039]

Can I just confirm that you were able to run it via an expansion battery? Ecoflow told me this didn't work when I directly asked them (which seemed very stupid to me). I have one and it takes about an hour to have any impact on a 3mx3m room but is then effective.

[@Jasonoid]

It works just fine off my Delta 2 and Delta 2 Max batteries. They charge and discharge just like the official add on battery.

[@garynelson1039]

@@Jasonoid Thanks so much for replying. I live on a 65 x12ft Widebeam canal boat in the UK which I am currently just about able to run, during the summer, using the AC200max (with B300 battery) and love watching your channel. This is the official response from Ecoflow " The Delta 2 extra battery can't be connected to Wave 2. So it can't charge the extra battery." It made no sense to me so I am really happy to know it does work especially given the difference in battery chemistry.

[@sleddy01]

I am curious how the truck experiment would work if reversed and only the hot exhaust was outside. I don't imagine much difference though because of the lack of differential.

[@Almshyakhi]

thank you for awesome review

[@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.

[@Jasonoid]

Great recommendation for the insulated exhaust hose! Is it a specific size or brand?

[@larrywong7834]

​@@JasonoidI use De'Longhi Insulated Hose Cover for Portable Air Conditioners (), DLSA003 It emits No Order. Insulates 5 inch exhaust hose Extremely well.

[@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.

[@injectionAI]

Definitely need to recirculate the cabin air to get best results I think

[@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.

[@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.

[@pj-3325]

Really well done. Tnx for all your hard work and research in this!

[@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 👋

[@SandiRose2008]

I couldn't help but notice the Wave 2 looks just like the Tesla Pick Up Truck from the side view. 😆 I like the handle placements and the weight. The Wave 2 would be great for my living room. With so many windows, it's the hottest room in the house! But, I first need to buy the Delta 2 Max and everything else I would need. I think I've made up my mind! 😂 Thank you so much, Jason, for always providing us with all the information.

[@Jasonoid]

Cyber Truck AC! haha

[@scootanow85]

So what is the power consumption when heating?

[@Jasonoid]

I was testing this during the dead heat of summer, I wasn't going to heat my house! LOL That video will come in the winter when I want to actually heat my home.

[@SetitesTechAdventures]

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

[@pineyken1251]

You think this will work well for a SUV? Living full time thank you for the video

[@Jasonoid]

This works much better in the heat as an air conditioner VS a heat pump in the winter. If you are planning to be using this in temps cooler than 40F, I'd recommend another heating option.

[@pj-3325]

Great review! Wish the “puppy” worked via dc w the ecoflow power kits. Just purchased a wave 2 w delta max 2 combo. W the current sale, better bang for buck than w the wave battery!

[@deswr1]

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

[@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.

[@Cobizybone]

Best video on power use of wave 2 thanks

[@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.

[@Noelshepherd]

Greetings Jason, This was a great review on the Wave2. I think it’s a little pricey for the cooling capabilities. Also, it’s too bad that you can only use dc with another ecoflow product.

[@Jasonoid]

Yeah. I think both DC mini splits and heat pumps are going down in price so these should drop down in price over the next few years. Since it's newer tech it's a little pricey right now.

[@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.

[@coryo617]

Will this work with ecoflow delta 1 ?

[@savagedan100]

But how well does it heat

[@TravelExplorer2040]

Everybody got paid suspensor I don’t see till now any body do temp test before and after in van or rv summer time

[@GeorgeOu]

Probably a lot more efficient if you spaced out the exhaust from the intake! You don't want to feed the exhaust back into the intake!

[@Jasonoid]

Probably!

[@marauderhot]

On the truck test you missed the benefit of recirculating the air.

[@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

[@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

[@markcrew3696]

I don't think no one has touched on pass through charging where the unit is sitting by itself with the battery and hooked up to a DC source say in your car. Will you be able to run the unit and charge the unit at the same time say through your cigarette lighter I know it's just a hundred Watts or some sort of DC booster. Remember this is just the unit with its battery sitting in your car without any solar generator hooked up.
