And it turns out to be an ac motor in the compressor causing the fridge and the battery to short out If it stalls on a coil. The ac motor burns up with the battery. The electronic, water dispenser, and the ice maker would probably be happy assuming it's a full bridge rectifier otherwise polarity would matter but most likely wouldn't break it.
To answer the original question, a fridge requires quite a lot of power to operate. Could be 500W. There's also power loss from the voltage conversion, so you need a battery and an inverter that are able to provide more than that - let's say 600W. Car batteries are typically 12V lead-acid batteries. 600W means 50 amps from the battery. That's a huge current. Lead-acid batteries can handle high currents for a short period of time, but high currents have a negative effect on the battery capacity. So my guess is that the fridge could work for a very short period of time.
Plus to add that modern kitchen stuff like that will throw on the compressor to cool the unit down with up to a surge of 1200w. Usually for 2-3 minutes as it engages the cooling pumps and moves the refrigerant.
I've run fridge freezer units off battery a few times (deep cycle lead acid, lithium/LFP)
Yeah but you are talking about hot tubs and they are talking about hot tubes so maybe the rules are different like the tube is really hot but is a poor thermal conductor. Or they misspelled tub and they really like burning themselves...... lots of options for interpretation here.
It could also be a gross sex term for a dick. During sexy time someone could say to me "yeah give me that hot tube" and I would be immediately less interested in sex.
Most adults will suffer third-degree burns if
exposed to 150 degree water for two seconds.
Burns will also occur with a six-second
exposure to 140 degree water or with a thirty
second exposure to 130 degree water. Even if
the temperature is 120 degrees, a five minute
exposure could result in third-degree burns.
To be honest three degrees burn doesn't sound bad. I'm looking at my protractor and as long as you aren't far away from the tub three degrees shouldn't burn that much
Before anyone says it's so stupid it might work, makita beat you to the chase. It has a real heat pump (reversible refrigerator). I really want one though.
You will need to shop for a car inverter. Find one that is at least 1,500 watts, and it will help you power your refrigerator for up to five hours—usually without damaging your car battery. Considering how much food we keep in our refrigerators, a $200 car inverter is a bargain!
Nah, it's definitely easier during a tornado to go outside, jack up my car, remove the wheel, remove the wheel liner, and then pull the battery from inside the bumper because that's a really convenient place to keep a car battery. Then I just have to lug the battery inside, hook it up, and keep 2 small children and 3 dogs away from it. Much easier than a generator.
This reads like a shitpost. The math is eh, okay, but the explanations are totally wrong. I won't even try to figure out what "runs off watts" means.
Enough of any electricity source, using various converters can get any appliance working "technically speaking", but in the end the amount of energy available at the source and the rate of consumption at the end and any intermediates. So "technically" an AA battery can power an industrial electric press, but only for a fraction of a microsecond, using a lot of charge storing infrastructure and with a lot of changes to get the tiny bit of DC into the machine requires to operate, likely 3 phase AC power.
A proper explanation would say a lead-acid car battery provides power at around 12V and electric camping fridges nominally operate around 12V so you can connect them directly and operate it (so you can sorta say they both run off DC volts?). If not you would need a buck or boost converter. The available energy of the battery (Watt-hours is a useful unit here) and the consumption rate (in Watts) of the fridge determine how long you can use it on the battery.
