Every day comes with its own struggles, but cold coffee (that's intended to be hot) shouldn't be one of them. Expensive smart mugs and insulated tumblers aren't the only option for keeping up the temps of your fresh brew, however. The portable Mr. Coffee Mug Warmer is an Amazon bestseller with over 8,900 reviews and 4 out of 5 stars — and it's only $10.99.

The Mr. Coffee Mug Warmer keeps your hot drinks hot by acting like a small hot plate. It's basically a heated coaster. Just plug it in, turn it on and place your mug on top. It's easy to clean and easy to take with you anywhere you go, but also makes for a great desk accessory.

One happy and caffeinated Amazon reviewer wrote, "It's going on a little over a year since I got this coffee warmer & I felt I needed to let everyone know that this is the best coffee warmer I've gotten. I work 7 am to 5 pm and it is on the entire time, 5 to 6 days a week. It keeps my tea at just the right temperature. Not scalding or room temperature like other warmers I've purchased."

Another Amazon reviewer emphasized how convenient the warmer is: "I'm a chronic coffee forgetter. I can't drink it straight from the brewer (too hot for me) so I set my mug down to cool slightly and often get distracted. Of course I then come back to my coffee to find it's already cold. I've currently got the warmer at my office and it's working great. I can sip my coffee leisurely over an hour and it's still nice and warm. Notice I said warm, not hot. This will not keep your coffee at just brewed temp short of putting a silicon lid over the top after brewing."

If you are looking to keep your coffee at near-scalding temperatures, we also suggest using an easy-to-clean silicone lid that you can simply rest on top of your coffee mug after brewing or while warming.

There are tons of coffee warmers (like this smart one by Ember that retails for $99), but the Mr. Coffee version is by far the best you can get for your buck. You can shop the top-rated coffee warmer above!
