Buyers Guide for the Best Smart Coffee Mug

Is it for home/office or travel?

One factor to consider when buying a smart coffee mug is to ask yourself where are you going to use the mug? Is it for home, office, or travel?

It is because smart coffee mugs come in various designs, which may not be suited for your intended use. If you intend to use the mug for the office or at home, you can purchase the ones designed purely for such purpose.

Two good examples are the Ember and Glowstone smart mugs. They look exactly like the usual mugs and are not suitable for commutes or travels.

Do you require App connectivity?

Smart coffee mugs that have capabilities of connecting through an App via smartphones are more convenient to use. The App provides other functions that are not included when you use the smart mug alone.

However, this smart mugs can also work without the Apps, though you might lose some features like setting up the mug to maintain your desired temperature. Without the App, the mug will retain the temperature default set by the manufacturer.

If you’re more into convenience, get the one with App connectivity.


The capacity of the smart mug is a factor often disregarded by many coffee lovers. If you’re just a regular coffee drinker, you might be satisfied with a 10 to 13 oz mug.

However, if you’re a coffee binger, you might need to consider getting a larger mug. At least a 16 oz smart mug will be great for a huge coffee gulper.

Battery life

Not all smart coffee mugs have rechargeable batteries; some work directly on a car charger. But if you’re getting those that run on batteries, you might need to consider how long the battery lasts.

Some batteries can last an hour or three, or maybe less. The Cauldryn smart travel mug gives you the most extended battery life of 10 hours.

So, depending on the purpose, you might need longer battery life for long travels, or you can pick the ones with batteries that last an hour if you’re using the mug at home or office.
