How much should a coffee mug cost?

The cost of a coffee mug varies widely, mainly based on the mug’s size, material, and extra accessories or functions. Basic travel mugs and tumblers typically cost anywhere between $10 and $20 on Walmart, with some costing as little as $8. On the other end of the spectrum, large self-heating mugs and tumblers can have a price tag of well over $100, with a few coming in at nearly $200.

What should I keep in mind when buying a new coffee mug?

When buying a new coffee mug, there are a few key elements to keep in mind. The mug’s size and material, cost, how much coffee you drink, where you plan to use or take the mug, and additional features are all important factors to consider.   

You should focus your search on mugs that are sturdy and comfortable to hold. Those with a compact design, easy-grip handle, and durable build are the most valuable ones, as they’ll let you enjoy your beverage without any hassle.  

Think about where and when you like to enjoy your morning brew of coffee, chai tea, macchiato, or warmed milk. Do you like to sip on it throughout the morning commute and your day at the office? Or are you someone that likes to enjoy it fresh and hot before you head out for the day? You should also consider how much of these particular drinks you usually have in a given day, as this will play a huge role in determining the size of mug you should purchase. 

Finally, the extra features that some mugs have, including auto warming, auto shutoff, warming lids, and more, can have a huge impact on both the drink quality and your safety. The most innovative and valuable coffee mugs have self-heating technology and an option to automatically turn off after a certain amount of time, as well as ultra-secure warming lids, such as our state-of-the-art ionmug. If these sound like important aspects of a prospective mug, then the ionmug and Charging Coaster may be for you. 

Keep all of the information above in mind when it’s time to buy a new mug. Whether it’s for yourself or a loved one, the right coffee mug can make a world of difference in how each day begins.

What’s the best material for a coffee mug?

Coffee mugs are typically available in several different materials. Here are some of the most common ones. 

Ceramic mugs are often less expensive and more durable when compared to most mugs. These mugs are mainly intended to be used at home, since even the thickest ceramic mugs tend to crack when dropped on the floor, thus making them much more suitable for your morning routine before you go to work. A huge benefit of ceramic mugs is that they don’t often absorb or transmit the flavor of your beverage, so you can still enjoy the full and natural taste of your coffee, tea, or other drink of choice. 

Stainless-steel mugs are another popular choice among coffee enthusiasts. Durability is the main advantage of these mugs, as they very rarely crack or break if they’re dropped on the floor. Like ceramics, stainless-steel mugs are not porous, and the material will not influence the flavor of your drink. However, it can help keep your coffee hot for a longer period, which is why it is the preferred choice for travel mugs. 

Plastic and acrylic coffee mugs are also fairly durable and affordable, but these types of mugs may end up changing the taste of your coffee. Plastic mugs are porous and can allow toxins from the material to mix into your drink over time. Individuals on a tighter budget can certainly use these mugs in the short-term without issues, but it may be wise to invest in a ceramic or stainless-steel mug for the long run.  

It’s up to you to decide where and when you plan to enjoy your beverage. If you’re on the go a lot or like to sip on some hot decaf on the drive to work, then a stainless-steel travel mug might be your go-to. Those that like to consume their cup of Joe before they leave the house, however, may prefer ceramic instead.  

What’s the best size for a coffee mug?

This ultimately comes down to how much coffee you drink every morning. Most coffee mugs come in sizes ranging from 8-12 oz 

However, those that drink lots of coffee or tea before work each morning may find that this amount is not enough. Those using travel mugs often take them to work and sip their beverage during the daily commute. Anywhere between 16-24 oz. may be a more suitable amount for true coffee or tea lovers.  

If you don’t drink coffee or tea very often, prefer cold drinks, or like to enjoy certain beverages in smaller portions, then there are also 3-6 oz. mugs available. The 12 oz. ionmug, though, is just the right size and can be a happy medium for just about anyone, no matter how much coffee, tea, or hot chocolate you sip each day.
