Mini USB Cup Warmer

The Problem

Ever start your coffee hot, then get distracted by emails and bam—it's a chilly disappointment? That first sip bliss fades fast, leaving you chugging cold sludge while your focus tanks.

The Solution

Plug this mini coaster into any USB port—laptop, power bank, car. Pick from 3 heat levels to hold your mug at perfect temp. Coffee, tea, milk? Stays hot for hours without boiling over.

Why It Works

Thermostatic sensor auto-adjusts heat so drinks don't overheat or cool off. Aluminum plate spreads warmth evenly under mugs up to 4" wide. USB-powered means no outlets needed—runs on 5V anywhere.
