Never Drink a Cold Coffee Again

Picture your coffee staying perfectly warm from your first sip to your very last, even two hours later.

You already know the feeling of rushing back to a drink gone cold - that's why Warmhollow uses a gentle PTC heating plate to hold your mug at your chosen warmth.

All that matters is this: pick 55, 65 or 75 degrees Celsius, and your drink stays there, hour after hour.

The built-in 8-hour auto shut off proves it was made for real desks and real forgetfulness, so you can relax and let your warm drink wait for you.

Why 10,000+ Customers Love Warmhollow

✔ Say Goodbye to Cold Coffee Rushes - The warming plate holds your drink at your chosen temperature so you never have to gulp it down before it turns cold.

✔ Pick Your Perfect Warmth, Every Time - Three touch settings, 55, 65 or 75 degrees Celsius, let coffee, tea or hot chocolate stay exactly how you like it.

✔ Stop Worrying About Leaving It On - An 8-hour auto shut off switches the warmer off on its own, so a forgetful morning never becomes a safety worry.

✔ Skip the Mug-Shopping Guesswork - The flat heating plate works with most ceramic, glass and stainless steel mugs you already own, so there is nothing new to buy.
