Running these analyses costs money. Buy through my links to help keep lights on! I may get a small commission.
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'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.
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.
