Rated Cooling Amps (AHAM) 11.9

This thing is close to tripping most home breakers. Just a few devices on the same circuit and TRIP!
All Space heaters use 1500W. This will use only 1440W.

I got the 12k BTU window unit (Rated Cooling Amps (AHAM) 12.17A) and setting it to max cool on eco mode uses <6A (<700W) and that's to get a 200 sqft. 84F room down to 74F, which takes <10 min.

Once it reaches 74F, running it for the next 10h to keep the room at 74F (assuming the unit does not have gaps to the outside and the room door is closed inside) takes <0.5kWh as measured by a kill-a-watt and it mostly takes <1A throughout the night.

Charging a Leaf on the same circuit (12A continuous over 12h) on the same 20A circuit along with a ceiling fan and some eco bulbs did not make it trip.

The portable units are a lot less efficient than the window units but I imagine it'll be fine as long as it is on eco mode if you have other high current devices on the same circuit (like a car charger).

This looks the same as the frontpage deal from Sam's Club, except this is $24 cheaper.

Am I missing anything? This model seems to have a higher BTU rating (12k vs 10k).

I have this same unit and have put it through 2 summers of use without tripping a breaker. Its on a 20A circuit, but that circuit also goes to half the kitchen outlets. Running this AC and another high-draw kitchen device hasn't been an issue (Air Fryer, Blendtec Blender, 4 slice toaster, Ninja Turtles Pizza Machine--Not all at once, but I have had the air fryer and blender going while the AC is on).

I have a Hisense non-inverter portable AC and that would trip a 15A circuit several times a day, with nothing else being used. It is essentially just turning on and off all the time, which will increase the chances of tripping vs inverter-style AC.

I wonder if you put the inverter style AC on a 15A circuit, how well it would do. Most people won't know which outlets are 20A vs 15A and will be hooking them up to a 15A circuit.

sams model #MAP12S1TGR-S costco model #MAP14AS1TWT-C so I guess different somehow someway but same ducting, etc. I guess the 14 makes it a bigger unit? I am in for the Costco model TU

Pretty much, the Costco model is 12k and can cool up to 550 sqft while the Sam's only 450 sqft. I looked at the Sam's model but it wasn't strong enough for my needs - this one is.

Got the heat pump version in the same deal last year and we love it. Since it's an inverter unit, unless you are taxing it heavily it will rarely run at the full 12 amps, making it usually possible to run on a circuit with other appliances.

I don't get how it's "close" when it pulls 12A / 1,300 watts max out of a 15A / 1,800 circuit.

Don't plug another large appliance into the same circuit. No different than a microwave or a large vacuum or a fridge.

So if I wanted to run this on a generator, I could only share the extension cord with 1TV, 1 Hotspot, and a half dozen lights or so.

I'm crushed. Frown I will have to run a second extension cord to use the microwave at the same time.

Most people wouldn't care. If it keeps flipping the breaker, they'll go hmm and try a different outlet.

Would a 40 foot16 gauge outdoor cord be enough to run across the living room? Or would I need 14 gauge?

Costco carries 50ft 12 gauge cords on reels for $40 online. https://www.costco.com/link2home-...APP=SEARCH

According to this chart 14 guage should be sufficient, but if you want the option to power more things, I'd bump up to 12.
