RolliCool App-Enabled 10,000 BTU Mini Split AC Unit

I'll just paste a comment here that I left on Amazon. Ignore the RV specific part of what I said, it was in reply to someone considering this unit for their RV. Dat EER Tho; I'm sorry to say that you shouldn't consider this unit for an RV. Ironically, that's the only reason I am here. I live in an RV full time. It's ideal in theory, however the efficiency of this unit is CRIMINAL. I know this is an issue they are well aware of too, since nowhere on their site or even here on Amazon do they mention the efficiency, or lack thereof. Most companies boast proudly about the efficiency of their unit. You won't be finding any energy star label on this thing. Frankly I am surprised that this is legal to be sold these days! The U.S. Department of Energy should throw a fit at this thing. I'm not here to cause damage to this product or brand. I've been interested in a product exactly like this one for years. I've built my own mini split in this size, but achieved far higher efficiency than this myself. :/ Why does this not use R290? Zero ODP, Extremely low GWP, legally allowed refrigerant in the USA now, (Along with R600a - FINALLY) has a higher molecular weight and thus would better serve a device that is more prone to leaks with the removable coupler, and unlike R410a is NOT a zeotropic mixture with mismatched boiling points. Which by the way makes the intentionally introduced leak in the system more severe as the lower boiling point refrigerant escapes sooner and leaves behind an incorrect mixture. Anyway, unless you are never planning on boondocking at all, or will exclusively use hookups with unmetered (unlimited) electricity you should avoid something like this unit entirely. It's cool that Rollibot (the manufacturer of this product) is offering refunds, but it's intentionally deceptive at best to avoid putting down any tech specs on the sales pages for this thing. They KNOW it's hideous. They probably wish it wasn't legally required to be on a label on the unit it's so bad. All that aside, for some people it might be the required AC due to a lack of competition for the format. Perhaps they are relying on a combination of that and consumer ignorance to sell these. IF you have no care for energy use conservation and have a need for this format then it's your lucky day. *edit;* Just for laughs I looked up the legal minumum efficiency of a split central air system (Which does not pertain to window or mobile units, but gives you an idea nevertheless.) that is less than 45,000btu/h. What is it? an EER of 12.2. Think about that. This unit is reported by the manufacturer to be 7.53 EER. This means that this unit takes almost TWICE as much energy to cool the same amount as a unit with the LEGALLY ENFORCED MINIMUM EFFICIENCY ALLOWED to be installed into a home. Again, central air is not the same as this categorically. However you would be wise to note that energy use to performance is universal. It may actually cost you more to cool only one room with this unit than your ENTIRE HOUSE with the crappiest central air unit you could legally buy as of January 1st 2015. Wow.

I'm honestly more interested in using it as a dehumidifer (vs traditional dehumidifiers that dump the hot air back into the room). The really high cost is an issue, though...

Ah yeah, I forgot about the dual hoses. They're annoying to shop for since searching "dual hose portable air conditioner" just returns every portable AC unit regardless of hose count.
