If you need a more compact unit, the Eco Flow Wave 2 or Wave 3 are fantastic. Two summers/winters on my Wave two. It heats at 6100 BTUS and cools at 5100 BTUs. Expensive, yes. However, they can run off of their own battery for 8 hours and can be recharged via solar or car charging.

I have the ECOFLOW wave 2 in my 2016 medium roof ford transit conversion van! The back living space is about 11.5 ft by 5.5 feet. The ECOFLOW is a portable AC unit and I’ve used it for 2 different trips now. The first 4 day trip I used it in Daytona, Florida in 65-100 degree weather. I had 2 holes in the side of my van for intake and outtake, but pulling 100 degree air from outside doesnt cool down the van at all! It only worked at night for this trip. I learned that it works infinitely better to just pull air from the inside of the van, and still have the single outtake vent sending the air outside the van. That way as the van is cooling down or warming up it makes it easier for the AC to work. I did this for my second trip in 62-85 degree weather in NC, and the ac works pretty well. Also the ac works great at any outside temperature with the vehicle driving and ac going, no need to pull air from the front to the back you can just turn it on and make sure the outtake vent is set up. If you want to cool everything down super fast I suggest just putting a fan blowing air from the front of the van while driving and put the ac on in the back. This makes my van ice cold. Other advice/info: My van needs better insulation [I have the walls, ceiling, and floor well insulted but the driving area need to be insulated off from the back of the van (i plan to do curtains lined with wool) and the sliding door and back doors need more insulation (also plan to do curtains lined with wool] once I do this I believe the ac should be able to work better in more extreme weather without the vehicle on. I use the 2400 pecron battery and 2 200watt pecron solar panels that are mounted on my roof to power the portable ac unit.

I've had an EcoFlow Wave 2 portable aircon and we bought an adaptor for the window to mount the pipes that circulate air from Takealot. The adaptor basically sticks along your window frame with a Velcro and zip system to go around the outflow pipes and helps keep it cool inside - relatively easy to uninstall if you move. We've for about 2 years and it works really well in summer. It is a bit pricier than a standard aircon but it also has the option of buying backup batteries for loadshedding and the installation etc was really easy by ourselves.

I used Ecoflow Wave 2 for a whole summer. Works pretty decently. The Wave 3 is even better

I have a wave 2 and if you insulate the exhaust hose and set up the hoses properly its very effective

Yep used the wave 2 in my 28ft Airstream at night since I couldn’t sleep with the rooftop AC blowing. Set the unit up to drain out shower and blow directly into rear sleeping cabin. It was triple digits daytime and about 70/80 at night.

Trying mine out for the first time in my small trailer eight and a half by five and a half fully insulated 2 in thick insulation walls and ceiling and floor sun finally went down and steel cooler outside than it is in the trailer and air conditioner's been running for 3 hours wish I would have took it out earlier and tried it out and seeing if I could get my money back would not recommend would not recommend would not recommend. I have this thing sitting right at my window with maybe five of the clicks out on the hose so it's running straight in and it's just not doing it. Really disappointed. I'm handicapped and my medical conditions don't tolerate me heat and going to find something different.

I bought my eco flow wave 2 last year. I’m very happy with it. We have a box camper though. It cools it well especially when the windows are blacked out. Works great on the lowest setting if you just put the vent into your sleeping area. The Bluetooth app for the phone works nicely to turn it on or off from your bed. I wouldn’t want cool anything more than a box camper or small van with it though. Have it charging from 400watt solar.

An EcoFlow Wave with a Delta Battery pack and at least 800 watts of solar. But for the cost, you are better off with Mister Fans and/or that Ryobi Shop fan that runs on a 40-volt battery.
