Factors to Consider
Consider the following factors when shopping for a coffee cup warmer:
Power
Coffee mug warmers are either electrically-powered or battery-operated – this also makes the difference between a corded and a cordless mug warmer.
Battery-operated mug warmers are ideal for use on the road and when you need less clutter on your desk. They are also ideal in instances of a power outage. If you prefer a cordless mug warmer, go for one with at least an hour of battery life so you can use it for longer.
Corded mug warmers are more powerful than battery-operated mugs. You can use them all day without stopping to charge them. Choose one with a cord of at least 60 inches.
Plate Size
Choose a coffee warmer plate size based on the sizes of mugs you have. A large warmer plate with a small coffee mug wastes a lot of power and also adds clutter to your desk. Fortunately, most of the warmers on the market accommodate a standard-sized coffee mug.
Temperature Control
A coffee mug warmer with an adjustable temperature lets you maintain your coffee at your preferred temperature. Models with only one temperature setting are more affordable but less convenient as you might be forced to switch them on and off depending on the temperature of your coffee. You might pay more for a warmer with temperature control, but it is more convenient as it keeps your coffee just as hot as you want it.
Safety
Being electric devices, mug warmers must-have safety features. Safety features on most mug warmers include an indicator light that shows when the plate is hot, non-skid feet, a cool-to-touch body, and an auto-shut-off feature.
On some units, the indicator light blinks for a few minutes after you switch off the unit to warn that the plate is still hot. Another important safety feature is the waterproof plate that ensures short-circuiting does not occur.
Design and Ease of Use
Because you do not want clutter on your office desk, a small and compact coffee mug warmer is preferable. However, ensure that the plate has a diameter large enough to accommodate your mugs.
You also need an attractive design with a smooth finish. Stainless steel warmers look great on your desk, but they are relatively expensive. Most of the units feature white heavy-duty plastic bodies in neutral colors. A neutral color is great as it complements the décor in your home or office.
If you need a warmer to bring to your next trip, you can choose a heated coffee mug. Instead of a separate warmer, the heated coffee mug has an in-built battery-operated warmer. This is convenient as you can walk around with your coffee in your mug as it gets warm.
Ensure the buttons or knobs are easy to reach.
FAQs
How warm does a coffee mug warmer get?Some coffee warmers get as hot as 200 degrees Fahrenheit while others barely get to 130. When shopping for a mug warmer, pick one that heats between 130 and 150 degrees Fahrenheit as this is the ideal coffee-drinking temperature. Any plate hotter than 200 will boil the coffee while a plate below 130 degrees might not be warm enough.
How long can I use a coffee warmer?You can use a coffee warmer the whole day. Electric warmer without auto shut-off feature will never go off even after so many hours of use. A mug with an auto shut-off feature might go off after an hour or four hours – you will have to switch it back on if you need it. Battery-operated warmers stay on as long as the battery allows, usually one hour, and then you have to recharge them.
Does a mug warmer hold all sizes of mugs?Most mug warmers will hold the average standard coffee mug – if your mugs are not extra size, you do not have to worry about the size. The average diameter of a coffee mug base is about 8cm and most of mug warmers have a diameter larger than that.
Summary
