What to consider when buying a thermos

As the high-performing models above demonstrate, not just any old thermos will suffice when it comes to meeting the rigors of use outdoor. Of course, these models were not simply chosen randomly; rather, we determined that each of these models deserved recognition based upon their outstanding specifications and performance in the field.

We’re not here to keep secrets, though. As such, we want to share the criteria we used to evaluate each of the above models with hopes that you’ll use these same criteria while you complete your own independent comparison shopping. With these criteria in mind, we believe that you’ll absolutely find the best thermos to fit your personalized needs and budget.

Capacity

At its very core, a thermos is a specialized container designed to preserve its contents at the user’s desired temperature. As such, a thermos’ internal capacity can go a long way towards differentiating itself based upon your anticipated needs. For example, while some folks only need a small thermos to accommodate their children’s hydration needs, others may desire a larger carafe-style thermos in order to keep their daily coffee palatably warm.

When it comes to thermos listings, “capacity” and “volume” are often used interchangeably. As such, you should remain vigilant for volume-based measurements when determining how much a particular thermos is able to hold. While most small and medium-sized thermoses denote their capacity in ounces (oz), some larger models may denote their storage capacity in liters.

Temperature preservation capabilities

In addition to capacity, most thermoses are fundamentally compared based upon their built-in ability to preserve their contents at a palatable temperature. As anyone who has ever held a hot cup of coffee or a sweating can of soda can surmise, not all food and beverage containers are able to performing this task. Thermoses, as it turns out, actually use a specialized convection method to ensure that contents within the holding chamber remain uniform for as many as 40 hours.

To this end, most thermos manufactures communicate their models’ temperature preservation capabilities in a measurement of hours. While smaller models typically carry ratings between 5 and 7 hours, some larger, reinforced models are able to keep their contents piping hot or ice cold for 24 hours or more.

Also, a thermos’ temperature preservation capabilities may be determined heavily by its internal construction components. Typically, a thermos’ inner chamber is made of a specially-coated glass that ensures a uniform distribution of heat throughout the internal vacuum chamber. However, many brands also make use of stainless steel chambers that are equally efficient while also remaining sanitary and durable.

Durability

If you intend to take your thermos outdoors, then you absolutely must take durability into account. The great outdoors has a tendency to cause accidents to occur, so it is essential that you pick out a product that can remain sturdy and productive in the face of unexpected impacts.

Store-bought thermoses tend to feature plastic exteriors. While these models are cheap, they are also prone to breakage after even a single impact. As such, a wise shopper should invest their money into a more reliable, metal-encased thermos. These can be made from any number of resilient metals, though most use a specialized steel with a wear-resistant coating (such as powder coating).

Cap seal quality

If thermoses suffer from any single chronic shortcoming, it is their tendency to leak through the cap after a period of use. For those that use their thermos every day, this can be a real hassle that may necessitate a costly replacement down the road. As such, a mindful thermos shopper should always evaluate a prospective model’s cap seal quality before hitting the “buy now” button.

Compared to other thermos specifications, this quality is firmly based on objective performance. As such, one of the best places to look for information on a given model’s seal quality is in the user reviews. If you notice any trends within these reviews, you’ll be better able to decide in favor of or against that particular model.

Tips for maintaining your new thermos

In order to keep your new thermos at peak functionality, you must care for it according to its manufacturer’s instructions. At the same time, maintaining your thermos also means ensuring that it remains fully sanitary from use to use.

Each thermos requires different types of routine maintenance, often depending on what materials they are made from. However, the following tips will help most stainless steel thermos owners attain the most functional use out of their new favorite vacuum-sealed container:

  • Always clean your thermos with warm, soapy water before using it for the first time
  • Never microwave your thermos to pre-heat it
  • Always leave some space below the thermos cap to prevent dangerous spillage
  • Do not immerse your thermos in water to ensure that the vacuum chamber does not become compromised
  • Do not store carbonated drinks in a thermos, as the released pressure may cause the cap to dislodge forcefully
