Well, dang. I am waiting on delivery. Guess I'd best do some serious testing. I did get excited to see that it will sit between the promaster seats as I don't want to do any serious permanent installation or drilling.

Its probably going to suck unfortunately, don't bother opening the package just send it back.

Friend of ours received theirs on Friday. Wouldn't even handle the sensible load in Flagstaff. They have a 6 ×7 bed area that is isolated from the rest of the van. There was very low humidity @ 90-95⁰.

Disappointing, because Ecoflow products generally have decent build quality compared to other brands.

Its also amazing what a cheap window unit can do for $200 in comparison. Just gotta find a way to power it.

I am thinking about a portable unit vented out of a maxxair fan. Make a plywood backed/insulated board to fit the opening with a hole for the ductwork. Seems I’d be better putting more $ in my battery bank than wishful thinking.

You can never go wrong with a fully charged beefy battery bank when it comes to running electric heat or air-conditioning.

Of course, you have to have the means to recharge that large bank. A small generator(1k) would be great if your inverter has power assist. Myself, I use the solar on my cargo trailer to supplement when using a/c, at least for the time being. I can't wait until I find a cabinet 12/24 vdc unit and can get rid of the rooftop unit. I am shooting for 1k to 1.2k of panels on the van roof.

We don't do humid weather, use a portable evaporative cooler for any weather below 105⁰f, and if that doesn't do the job, we turn the key and head for higher altitude.

None of this strategy has been cheap, but hey, surviving comfortably in a sticks and bricks is not cheap either. Especially when the humidity gets unbearable.

First world problem. Third world countries have endured or adapted. We are just grateful we had money to throw at the issue.

I was out in Tahoe for a week last week and got to try my Wave2 for the first time. I just used the supplied foam template against my sliding bunk window (with bugscreen). It fit "OK" and I could definitely feel hot air blowing out the rear vent.

Given that I had a sub-optimal setup with it, I have to say that I was really underwhelmed with the performance of the AC.

I think maybe 90-100F is just too hot for this unit, i suspect it would be OK in 80f temps.


I think im going to hold on to the AC for use in my apartment in the summer on hot days, but i dont think i'll be keeping it in the van when i expect temps to be high like it has been.

in case someone wants to see the inside minus the blowers

Still need to paint the vent to match the body color.

Weather has been cool so haven't had a chance to check the AC performance.

Very disappointed that the Wave 2 will not run off of the house batteries.

Hey what material did you use to make th cutout for the window for the exhaust?

Is it like wood? By any chance do you have a link?

Hi all, I have lessons learned.

1. Both intakes should be drawing inside air. The HEAT mode needs incoming air warmer than about 41F. So if u are parking for the night and sucking in freezing air - you will not get heat. When you park the van after a days drive, the air in the van will be above the 41F mark and stay that way overnight when running in heat mode. (I only one hole in the van for EF waste air.)

2. If you are off grid, it kind of sucks that you have to purchase the EF battery. BUT...this battery has enough stored energy to keep me reasonably warmed up or cooled down overnight. During most days my 400watts of solar panels easily refill the EF battery during the day. I think it is a ten amp max via 12volt charging ports - not enough to run compressor, but enough to charge EF battery during daylight hours.

3. Connect the drain line to your van gray water tank. There is a toggle on your EF app for pumping/draining out water.

4. We have a tall closet who's door matches the width of the hall to our elevated two person bed (sideways mounted). So we can take advantage of each BTU coming out of EF by opening the closet door all the way so it becomes a closed bedroom door.
The EF conditioned air is sent to this closed "bedroom" to heat/cool this smaller space.

5. Twelve volt Booster Fans (like the ones used in computers). I did a lot of testing of the EF and found by helping the little squirrel cage fans inside the unit with booster fans for exhaust and conditioned air, you get better performance. I put a little rheostat on the conditioned air outlet so I can reduce noise for sleeping.

6. I did permanently mount my EF in the top shelf of a cabinet. No way was I going to have large hoses and power cords filling up my promaster living space!

For us, parking in loves or cracker barrel, the EF has made long road trips much more comfortable. You just have to make accomodations for it.

The outside is polywall glued to 1/8 particle board.
