A Little Background

A thermos is used for keeping things hot. Like a bigger version of the travel mug you use at the office or while cycling across the country, a thermos is designed to keep a constant temperature while time passes by – but on a bigger capacity than a regular mug. Generally, the purpose of a thermos is not just for drinking, but also for personal hygiene such as washing, bathing and others. A thermos is also handy if you want many people to drink hot coffee or chocolate in one go.
Thermos or vacuum flask – people get confused a lot when pertaining to vacuum flasks because they are generically labeled as “thermoses” instead of what they really are – vacuum flasks. The Thermos brand is just a brand but it was the first commercialized vacuum flask so it monopolized the world. Eventually, the word “thermos” now refers to vacuum flasks that keep drinks in their constant temperature, whether you want it hot or cold.
Drinks can get cold once you venture on a trip outdoors. Imagine camping, trekking or backpacking outdoors. At night, nothing is more refreshing than a warm cup of coffee. If you are a solo backpacker, a travel mug is fine but if you intend to travel for days or if you are with a group or team, bringing a handy thermos seems to be a great outdoor companion in general.
A thermos is also useful at home so you can keep hot water hot (or cold water cold if it is designed that way). To get away from the hassle of turning the stove on again just to reheat your water for a nice cup of tea or coffee, most people can just use a thermos at home so they can serve hot water later without having to expend more fuel in the long run.
Economically speaking, a thermos is able to save you energy and fuel in the long run because you don’t have to keep heating your water all the time. This is extremely helpful if you want to reduce on your fuel consumption and this is also one of the biggest advantages of using a thermos at home. Supposedly, you want to have coffee now but later, your colleague also wants to have coffee as well. To avoid reheating water, you can just depend on a thermos for hot water, since it can significantly maintain the temperature of your water for a certain period of time, certainly longer than travel mugs, obviously, since they are built for heavy-duty use.
A thermos can also be used on cabins, RVs and mobile living where electricity and / or fuel resource may be scarce. Aside from its economical benefits, a thermos can also be used on the great outdoors where it may be very hard to heat up water without the use of fuel resource. If you are on a limited supply of energy then the best you can do is attain portability and on-the
Because it is highly portable, a thermos is usually made with an easy carrying handle on the go. However, some thermoses are made to have no handles but have a soft and cool touch exterior which does not burn you when it’s hot. And alongside that, the thermos may also have a feature which does not permit it to have condensation when you keep iced cold drinks.
The thermos works by keeping your water temperature constant. It does not heat up or cool down your water, contrary to popular belief. Most people think that thermoses are for heating – nah, they’re just a way to keep your water hot, that’s all. Obviously, you need a water heater source to heat up your drinks or cool it down using ice cubes or storing it in the freezer.

How We Picked

When considering a thermos for home or camping use, take note of the following features:

Capacity – this refers to how much water or content can the thermos take in and hold. Whether it is in ounces, milliliters or whatever unit you use, a thermos is a thermos – it will store liquid, unless it is also designed to keep food as well. Know the amount or capacity of a thermos before buying.
Span of time it keeps the temperature steady – this refers to how long will hot water stay hot (or cold water stay cool). A thermos is like a giant travel mug – it makes the use of insulating material to maintain a constant temperature within your liquid.
Ergonomic handling and design – this refers to how easy it is to carry with its handle and style or design. Take note that not all thermoses have handles – some just have a cool exterior which makes you feel like handling a vacuum insulated travel mug.

Other Frequently Asked Questions

Q: What is a thermos and what is a vacuum flask? Are these two different or the same?
A: According to Wikipedia , people often get confused when refering to vacuum flasks because the word “thermos” is the usual term we use for them. Thermos is actually a brand and company name of the manufacturers of the original vacuum flasks stemming from the invention of Sir James Dewar which was made into a commercial product by some German men who wanted to market the invention for its convenience. Later on, the word “thermos” became a generic trademark and this is why most of us begin to call a vacuum flask a “thermos” instead of what it is.
To cut the story short, a thermos or vacuum flask is a convenient flask which can keep hot drinks hot and cold drinks cold due to its vacuum insulation technology. Thermoses paved the way for making smaller water bottles that also carry the same technology, which are commonly called “travel mugs”.

Q: How important is it to get hydrated on the go?
A: According to the official site of Thermos , their campaign aims to teach people the value of storing drinks while traveling. One of the benefits is to keep you healthy and replenished after a long journey. The company also explained that life will be well-sustained with water that is safe to drink. The company aims to create better solutions in keeping the world hydrated on the go.
