Thermos vs. Stanley Insulated Food Jar

This is a comparison of the Stanley food jar versus the thermos food jar. Which is the best insulated food jar? In this comparison I compare the hot and cold retention capabilities of the 24 ounce Stanley food jar, and the 16 ounce thermos insulated food jar. Both of these insulated food jars work very well, and one is much bigger than the other, so you must decide what’s most important for you when choosing the best insulated food jar. This is a Stanley versus Thermos Insulated food jar test and review. 

Here’s where you can buy a 16 ounce thermos insulated food jar like the one in the video.

If you want to buy a 24 ounce Stanley insulated food jar, here is a link.

I think a better experiment would be to have the thermoses of the same size (both 17 oz or both 24 oz). This video did a good job showing the hot and cold comparison though!

Thank you for the honest review. Just looking for a good thermos for my son to bring hot lunches to school in. I though the hydro flask was so cute, but didn’t want to be a sucker for cute packaging. Thanks for the experiment and not just an opinion. I think the Thermos would be more appropriate for a child.

I have both of these and love them both.

I do and have done much camping over my 70 plus years. I camp a minimalist style of camping taking my choice of Stanley or Thermos to keep items hot or cold over time. Your tests are in keeping with my own tests especially for the different sizes you used for your testing. I own both of them in the exact sizes you used. Size, however, does matter. Those extra ounces of air in the STANLEY makes a difference in heat or cold loss. When sizes are exactly alike, the temp differences are minor. I do love the 16oz Thermos size for pre-cooked meats (chicken, etc) and the STANLEY 24oz for liquids. Nice video, done right.

I enjoyed your reviews for these 2 products. I bought both using your links. Keep up the good work.

I have the little thermous one. I work out of my car and love the little spoon that comes with it. I find it will keep the food hot for about 4 hours. It works for me for lunches very well. Washes easily in the dishwasher.

Tks for the test! One tip, next time to put the same amount of water on both because more termal mass will take longer to cool off.

I have both and I also have the 24 oz Thermos. I just swap the lid from the 16 oz one so I can still have the spoon.

I've had my Stanley for 20 years. A couple of years ago I emailed Stanley because mine started to get a little bit of rust, which was more so because I use to put ice in my cooler and when it melted, the Stanley would sit in water. They sent me a replacement, only asking for the number on the bottom. Didn't ask for a receipt or proof of purchase. Now I have two.

I prefer the Stanley because of the larger opening and it keeps food hotter longer, especially if I preheat it. I usually just run hot water from the tap in it in the morning.

I like the Thermos because it's a lot smaller while still holding 24 oz. And the spoon, while small, is nice to have. I ordered a spork that also folds and fits in the lid.

If I could only pick one, it depends. If I was still working outside 5/6 days a week and in the winter, I pick the Stanley. But working inside mostly, I prefer the Thermos. Mainly for it's size.

I use the 16 oz Thermos for mostly for chili.

Both are great.

This is such a fun and awesome experiment!!! Thank you for posting this up :)

Volume goes roughly by radius of cup cubed (^3) but area as squared (^2).
So a larger volume will contain more heat, thus it will take longer to dissipate.

The test is fair, don’t get me wrong… he compared the two containers and found which is better, but that’s part of the reason aside from any quality considerations.

You should have test the thermos food jar 710 ml instead of this one, because it has same capacity with stanley model, and the 710 ml model of thermos keeps hot 🔥 for 14 hours in comparison with 470 ml ( 9 hours hot 🔥)

Your Thermos videos are awesome! Thank you for sharing.

[liahonafrench]

Exactly what I was looking for today. Thank you for making this experiment and a video about it!

[Littrell]

I use the thermos and it works great and I like the built in spoon. I love all my stanley products too of course!!

[josephholliman]

Amazing! Stanley had a reputation in my mind of being a weany thermo keeper.

[jacklandismcgowan]

Thanks for the reviews. 👍
Ordered my Stanley pint beer glass yesterday after your review…should be here tomorrow. I’ll let you know the results of how long the beer stays cold down here in S Florida…You have to drink beer fast down here ….because of the heat😂😎.

[studywithmonika]

thank you very much, I went for thermos 470ml and 710ml, we'll see when it comes how it is going to work, but I like it

[eheheh]

For the Stanley, does the lid have a vent??? I read a comment on a video where someone asked how to clean the mold in the lid inside the vent because it wasn’t big enough to use a straw brush or removable

[chuloCFA]

Do you prefer Stanley or thermos? Have you ever tried the Zojirushi brand?

[tiffinstingkatssimple]

A good test in all. Thank you for this.
