Hayins Temperature-Controlled, Self-Heating Coffee Mug (Black - 16 oz.)

It has been a subtle but welcome change to incorporate this temperature-control cup into my everyday routine. It was inconvenient to constantly have to reheat my coffee several times a day, but this cup has made it unnecessary. Even on hectic workdays, when my coffee tends to sit a little longer than usual, the warmth remains constant, allowing me to sip carefully. The length of time it lasts between charges has also amazed me. I don't always have time to regularly recharge my devices because my mornings are so hectic. The battery in this mug is long-lasting, especially when I utilize the lid, which has reduced power consumption. Finding a heated cup that feels this reliable after multiple uses throughout the day is refreshing.

This coffee cup/phone charger is awesome! The mug is sleek and lightweight and easy to use. You can control it right on the mug or use the app to determine temperature. It is so nice to not have to microwave my coffee because it never gets cold! I put my cold creamer in it first and give it a few minutes to warm, then add my coffee. It is great to be able to carry the mug around and not have to be tethered to a physical coffee warmer, too. The base charges the cup and also allows you to wirelessly charge your phone, which is super convenient. Recommend!

The battery holds up well for my needs, and keeping the lid on really does help stretch it longer. I’ve been using the coaster when I’m at home, and it’s nice to just set it down and not worry about the battery at all. The auto shutoff is a lifesaver too, especially on those mornings when I’m in a rush and forget to turn it off.

Cleaning has been easy so far, just a quick hand wash and it’s ready to go again. I really like how simple and low maintenance it is. It’s been a great addition to my routine, and I actually look forward to using it every day.

This mug has been a great little upgrade to my mornings. The button on the handle makes it so easy to adjust the temperature, I usually set it just right for sipping while I work at my desk. It’s kept my coffee warm for hours, even when I’ve been distracted and left it sitting for a bit.

While I could imagine my life without one of these mugs, I don't want to. We started out with just purchasing 1 to share between my spouse and I. It very rapidly became the most coveted cup in the household, so then we purchased a 2nd one. These have been used multiple times every day for the past year! They even fit in the cup holder of a 4Runner, so we bring the charger along and have perfect temperature coffee all road trip long. We have also been known to warm up water in the cup and make hot tea (this takes a while, but is so satisfying on long road trips).
The battery lasts 2.5 hours on medium with the lid on. This is our preferred setting, so I don't know the battery life of the other settings. (Although I do like the option that I can make my drink warmer or cooler). These cups are very easy to clean, and extremely user friendly. We have continued to purchase (7 and counting) to give away as gifts, and each time get comments that it's their favourite gift ever.
But don't just take it from us - try one yourself. :)
