Kepwam Self Heating Coffee Mug 2, 16oz Smart Heated Coffee Mug, 150 Min Battery Life - Hot up to 149℉ Temperature Control Coffee Mug Warmer, Gifts for Women and Men (No APP)

It is very nice and does the job well.

Received it late but otherwise in good order.

This isn't KEEP WARM, this is KEP WAM and it keeps your beverage vedy, vedy WAM. Should be KEP HA because it keeps your beverage vedy, vedy HA. I absolutely love this wonderful Chinese product. I expected it to be a flop, but to my surprise the quality and craftsmanship is excellent. The battery lasts several hours, but keep it on the base with the white light on and it stays hot indefinitely. Excellent product and highly recommended.

I love my mug. I am one of those people that is constantly having to reheat my coffee as I get busy and my coffee gets cold. Easy to use, buttons easily accessible and I love that it has an auto shut off when liquid is low, no worry about overheating and it feels safe. Battery last quite awhile, easy to clean and love the charging pad. Would highly recommend

I wanted to give this mug a fair shot before writing a review—several uses in, and I can confidently say it’s a winner. This temperature control mug does exactly what it claims to do: it keeps coffee hot (not just warm) from the first sip to nearly the last. The mug is easy to use, with one intuitive button and a clear indicator light showing three heat settings: warm, hot, and “piping.” I prefer my coffee piping, and the high setting keeps it at just the right temperature for me. Battery life has been solid—up to 2.5 hours as advertised—and the five blue indicator lights make it easy to track remaining charge. Of course, using the higher heat setting drains the battery a bit faster, but that’s expected. One standout feature is the included charging base. When I’m at my desk, I keep the mug on the base while sipping, which helps preserve battery life. The base has two raised contact points that align with the inset conductor rings on the mug's bottom, so there’s nothing to plug in—just set it down and go. Simple and effective. There’s also an auto-off feature that detects when the mug is empty. While I haven’t tested it deliberately, I’ve noticed the last sip is sometimes cooler, which makes me think the mug powers down before it’s completely empty—a smart safety feature, especially if you’re forgetful or distracted (no one wants melted plastic or worse!). The mug holds a standard 8-ounce pour comfortably, even with room for cream—though I drink mine black and untainted. It also does a great job maintaining heat even without the lid, though I imagine it retains heat even better with it on. Bottom line: this mug offers excellent usability and functionality at a significantly lower price point than some of the better-known competitors. If anything changes down the road, I’ll update my review—but as of now, this is a fantastic value and a great buy.
