Thermo Cube Model TC-3: Thermostatically Controlled Outlet - On at 35-Degrees/Off at 45-Degrees

Fool-proof operation!

love this for my heated dog water bowl outside for my chickens

Great plug & play solution for keeping my outdoor 'working cat' warm and her water from freezing on these cold nights, yet not wasting energy in warmer weather. Temperature on and off seams reasonably accurate and device is rated at 1500W, overall a good deal at this cost.

Ok, not perfect but I'm really glad I bought this. This was purchased for my outside dog to run a heating pad and heated bucket. She get too hot inside our house so I have two 1/2 round k&h heating pads in her igloo. One heating pad I have plugged in directly to outlet, the other to this cube with the bucket to kick on when it get really cold. 1st-- initially doesn't work in my outside outlet. They are recessed (most are). I had to purchase an adapter for my adapter.(no pun intended). So, it now sticks way out. If it gets bumped hard it will fall out. But, so far so good. I Constantly check it. Attn. company farm innovators design flaw!!! Add an inch thick square block to the back of the plug and you'll have a much improved product. 2nd-- it turns on at a higher temperature then 36. I think it's on at 42 off at 49. ( test it by put a lamp outside. As the temp drops check to see if the lamp is on.) I really need this to be better. I already have one pad going, I wish it would kick on at closer to freezing. Our lab is literally hanging half out the door to cool off. She is 14 and swells because of both heating pads are on in 40 degree weather. I've been unplugging the other pad. Then if it's freezing go out and plug it back in. If it worked correctly, there wouldn't be a need to do this. I purchased a t-2 for 26 degree. Haven't tested it yet, but will and post results. If it works like this one, I may be using that one for my bucket and 2nd pad. The good news is I'm not going out in the middle of the night to break water

I have used these in my barn for years ,they work great and never fail

Tried to set up a battery heater for my older EV. I attached a couple heating pads to the bottom of the battery case, plugged them into the 35/45 outlet, ran an extension cord to this switch/outlet, put the under covers back on the car. Now I have a nifty battery heater *that does nothing at all*. I couldn't test the thing because it wasn't cold when I did the work. Now it's 20F in my garage, I plug in the extension cord, and nothing happens. The cord is fine, the heaters had worked (I could test them). Pretty sure this switch is just junk. Do yourself a favor and don't try to use one of these in a location you can't access. When yours turns out to be a dud, you'll regret it.

This is not waterproof, so I keep it protected out of the rain when used outside to turn on my heater used for the chickens water dispenser and a birdbath. If you use this on an outlet that is attached to a heated structure, it will not operate as advertised, the building residual heat will trick it into thinking it is warmer out than it is, you have to get it away from a heated building, unless your place is modern with tons of insulation and not like my 70 year old frame home.

As Described

I connected this to the block heater on board my diesel pickup so that I can plug in my truck and have the on board charger top up my battery and kick in the block heater only if needed. This has continued to work flawlessly for years and the temperature set points are about right for my application. Other temperature switches I had bought in the past, simply didn’t last.

I got this to control a small heater I have in my tractor shed. I don't need heat all the time, just when the temperature drops below freezing as the heater is only intended to make it easier to start the tractor. This adapter is doing the trick and seems to work well at allowing power flow within the stated temperature ranges. In the past I had to remember to go out to the shed to turn the heater on if it looked like the weather was approaching freezing. Now the system looks after itself and I save power by not running the heater when it is not needed.

We use this for a small space heater in our pumphouse for when it drops to -28 or colder outside. Which it never used to do, but now the winters have extreme colder. Our pumphouse was built at a time when it went to -25. Now with the destabilized arctic air masses in the winter we occasionally get overnight temperatures to -30. We plugged in a small ceramic heater to this magic plug and don’t have to worry about freeze ups. A small step to adapting to climate change.

Turns off and on as described. Works off of extension cord as well as an outlet. Ensure all plugs are connected snuggly or it may not operate correctly. Ground is a bit loose and can pop off of the cube, if placed into a tight outlet or extension cord, when disconnecting. Orherwise, the item works well.

You simply can't beat this item for simplicity and cost-effectiveness. We bought it to keep an insulated shed from freezing so we could store a bumper crop of winter squash inside. Just plug in any non-digital heater (digitally-controlled heaters will often reset and won't automatically start up again) and the device takes care of the rest. We did find that the temperature range to be slightly warmer (6-10 deg Celcius) than advertised (2-7 deg) but this could have been a result of the device being located on a cooler outside wall. If we had wanted it cooler, we could have plugged the device into a short 12 ga extension to move it away from the wall, but the warmer temperature was all right for our purposes. Again, overall, you can't beat the simplicity and price of this solution.
