ErgoCrafted HeatMat Pro Mug Warmer

Coffee has about a twelve-minute window before it slips into lukewarm and sad. The HeatMat Pro keeps it in the good zone. Set your cup down and the gravity sensor switches the plate on by itself; lift it off and it powers down on its own.

The heating surface is wide and flat, not the tiny puck most warmers use, so a mug, a glass, or a wide tumbler all sit flush and heat evenly. Worth knowing up front: it's built to keep a hot drink hot, not to reheat one that's already gone cold.

• Never sip cold coffee again — steady, constant warmth holds the perfect temperature
• Totally hands-off — the gravity sensor turns it on when your cup lands and off when it leaves
• Fits your favorite cup — a large flat plate for mugs, glasses, and tumblers alike
• Powers off anything — runs from a laptop, USB charger, or power bank
• Looks good doing it — minimalist matte finish that suits any desk
