MULTIPLE USES: Use this smart mug to brew coffee, boil water, cook freeze dried foods, brew green or black tea, heat up your soup, or regulate any drink’s temperature. COMPLETE SETUP: Includes a 16 ounce travel mug, 2.0 heating element, battery, desk base, power cord, and a lid; ideal for road trips, camping, hunting, and long days at the office.

An Overview On Smart Mugs

Smart mugs are an innovative way to drink your favorite beverage. — and make sure it’s at the perfect temperature from start to finish. There are effectively two kinds of smart mugs: those with an internal battery and heating element, and those that heat a mug while connected to a charging cable or pad. This latter type should be regularly returned to its charger to maintain its temperature.

If your primary complaint is coffee going cold at your desk, charger-dependent models may be a better option. If your main complaint is tea getting cold while in transit or meetings, you’ll want a travel mug with a battery.

All smart mugs must be hand-washed, due to their sensitive electronics. However, some feature a removable liner, which allows you to clean them with more confidence that you won’t damage the wiring or battery.

Do you prefer hot or iced coffee and tea? Some smart mugs can not only keep liquids hot but also cold, primarily due to the presence of insulation and effective seals. This allows for greater flexibility, especially if you and other members of your household prefer drinks prepared in different ways.

While battery technology is advancing by leaps and bounds, smart mugs still take up a certain amount of space in your cabinets, and they can be heavy. When purchasing a smart mug, consider the bulkiness and weight alongside the mug’s performance.

If you don’t want to carry around a thermos that weighs two pounds even before you add liquid, you may want to opt for a smaller design with less battery life. Alternatively, you could view it as exercise and use the mug as a weight for arm curls in your downtime.

The Smart Mug Buying Guide

  • Review your smart mugs before buying to make sure that they are effective insulaters. While better batteries can ensure a longer charge to keep your coffee warm, a well-insulated mug makes the warming element more effective. Thus, you can still expect some warmth even after the charge runs out.
  • Some people will be concerned about the electromagnetic energy of a smart mug being harmful to humans and pets, but rest assured that the charging field is very closely contained around the charging pad. Your mug will stop charging unless it is within a few millimeters of the pad; that is the effective range of the radiation it emits. So, unless you put it right next to your body for prolonged periods of time, you should have nothing to worry about.
  • If you select a mug that claims to heat a liquid from cold to boiling, be aware that this process will consume much more battery life than if it were simply maintaining a heated liquid’s temperature.
