Two freezers in one outlet?

I have no idea the peak usage of either device, if your local library has a kill a watt energy meter you can grab it and test both devices. Bear in mind that their use is not constant so you need to watch it for an entire compressor running cycle.
This assumes the library is open these days and even carries an energy meter (many in Ontario do).
Conversely the placard on the back may have peak amperage use. Or you can try contacting the company though for the old unit who knows if they have that info on file.

All that said i suspect you will be fine but i cannot guarantee it.

Why not get a larger freezer and just use one freezer?

Pop the access panel off of the freezer and read the Amp rating on the compressor, that would be its max current on start up. New compressors have very low starting currents, my chest freezer is about 3.5A. Modern circuit breakers also dont trip the moment you go over their rating. if both happened to come on at the same time the current spike wouldnt be high enough or long enough to trip with two moden freezers.

What that guy said. Find out the amperage. You can call the manufacturer. Sometimes they have it.

Conversely, my super old but still runs beer fridge my parents bought in 1989 side by side Maytag start up amperage is 17.5 for a split second.

Check the label on the back of the fridge to see the peak power consumption, and made sure the total of both doesn't exceed 15 amps (about 1700 watts) for a normal socket. That's unlikely.

The concern would be that the startup power surge of the motor draws a lot more for a fraction of a second, and if the two happened to start exactly simultaneously, it could trip the breaker. Let's say the compressor starts every 15 minutes in hot weather, and the surge lasts about 1/2 sec., the chances of a random simultaneous start (1 in 15 x 60 x 2) would come out to more than once a month.

The startup current draw probably isn't on the outside label, although probably is on the compressor motor itself. The easier way to tell would be to use a power meter, like the Kill-a-watt you can borrow from public libraries in Ontario. But they only cost about $20 to buy (try Amazon), and they're very handy to have around the house. All of them can measure peak amps on a device that's plugged into them.

Holy crap thats crazy, my 2 chest freezers and fridge dont add up to that.

One of the reasons Code said fridges needed a dedicated 15A circuit.

OP, it's hard to tell if this will be a problem or not. That old Woods freezer probably has a fairly significant start up draw. New fridges and freezers are more efficient running, and more efficient at start up.
They may be fine on a single 15A circuit. However, if there are any other loads on that circuit (washing machine, vacuum cleaner, etc) it may cause the breaker to trip.

You could run a heavy duty appliance extension cord to the washing machine receptacle and plug the new freezer in there, since they are typically on their own dedicated 15A circuit as well. You may end with the same problem, but at least you'll know sooner rather than later that the breaker has tripped. It could be several days before you realise both freezers aren't running the other way.

I’ve got a small freezer and small beer fridge on the same circuit and both can operate simultaneously without issues. But like others have mentioned, you’ll need to determine if amperage requirements for your specific freezers exceed 15A.

My brother is a P.Eng and had it for a while. He tested it when they were having circuit problems with a dedicated 15 amp line. I have had it for about 5 years now and have not had an issue. Its run off the basement lights which are all LED and never on though.

I wanted to buy this Danby upright freezer here, which is energy star certified:

Was going to put this in the basement storage room in the same 15amp wall outlet as another chest freezer. Not sure on the specs aa its an old freezer from the 2000's but I attached a pic of it below:

In this same room, there's also a washer and dryer if that's any help.

Would it be okay to plug both freezers in the same outlet? Would it affect the circuit at all? Will there be a power outage at all? Thanks for your time!

If you are concerned .. then plug them into two different receptacles.

Those receptacles need to be on separate circuits. Otherwise it solves nothing.

Old compressors have huge inrush current on start up.

Don't forget some freezers have self defrost which can also cause a problem.

Small chest freezers are very energy efficient and so the motor is tiny and should not be a huge load on a circuit. Fridges are much bigger loads. The only chance I see of a challenge to the circuit breaker is if both fridge and freezer motors were to start up at exactly the same time and with maybe other loads on the same 15 amp circuit.

That was my instinct. I was surprised the other day to find that my fridge is only rated for 5.3A
