Cooler Ice Metal Vacuum

In summary, the effectiveness of a metal vacuum mug in keeping drinks cold compared to a cooler bar with 300mL ice depends on the type of metal used, the insulation properties of the vacuum mug, and the ambient temperature and humidity. Generally, a well-insulated and thermally conductive vacuum mug can keep drinks cold for several hours, while a cooler bar with ice can keep drinks cold for a few hours. Other factors such as the design and construction of the vessels may also affect their effectiveness.

I guess the question is also when.

If you have some food or liquid to store. If you use a low quality cooler bag with 200mL to 300mL Ice pack at what point will a Vacuum seal with no Ice beat the cooler bag?

I guess at the 10 hour mark or 24 hour mark or at some very long period of time.

what is your definition of a " cooler Bag" ??

don't really know what you are referring to

1. Can a metal vacuum mug keep drinks colder than a cooler bar with 300mL ice?

It depends on the type of metal used and the insulation properties of the vacuum mug. Some metals have better thermal conductivity than others, meaning they can transfer heat more efficiently. Additionally, the thickness and quality of the vacuum insulation can affect its ability to retain cold temperatures.

2. How long can a metal vacuum mug keep drinks cold compared to a cooler bar with 300mL ice?

The duration of coldness will also depend on the factors mentioned above, as well as the initial temperature of the drink and the surrounding temperature. Generally, a metal vacuum mug can keep drinks cold for several hours while a cooler bar with ice can keep drinks cold for a few hours.

3. Is a metal vacuum mug more effective at keeping drinks cold than a cooler bar with 300mL ice?

It ultimately depends on the specific mug and cooler bar being compared. Some vacuum mugs may have better insulation and thermal conductivity than others, while some cooler bars may have better insulation and ice retention. It is best to research and compare specific products to determine which is more effective for your needs.

4. Can a metal vacuum mug keep drinks colder than a cooler bar with a larger amount of ice?

It is possible for a metal vacuum mug to keep drinks colder than a cooler bar with a larger amount of ice, but again, it depends on the specific products being compared. A well-insulated and thermally conductive vacuum mug may be able to keep drinks colder than a cooler bar with a larger amount of ice that has less effective insulation.

5. Are there any other factors besides metal and insulation that can affect the effectiveness of a metal vacuum mug compared to a cooler bar with 300mL ice?

Yes, the design and construction of the mug and cooler bar can also play a role in their effectiveness. For example, a vacuum mug with a tight-fitting lid may be more effective at retaining cold temperatures than one with a loose lid. Additionally, the ambient temperature and humidity can also impact the effectiveness of both vessels.
