During the holidays, our warm-hearted generosity and buoyant spirits burn brightly enough to resist the chill of cold December days. Your morning coffee on the other hand is another story. Keep you and your coffee warm this holiday season with today's WagJag: $17 for two USB mug warmers (a $30 value).

These technological marvels radiate heat into the base of your favourite mug, helping warm beverages retain their initial temperature without overheating the mug itself. With USB ports that let you charge it via your laptop, your caffeinated cuppa joe is always hot and close at hand, even when your other hand is busy typing out e-mails and arranging meetings at home or the office. A great gift for the caffeine addict in your family, this USB mug warmer means that your loved one will never have to make multiple fresh pots or (coffee gods forbid) microwave their chilled swill back to temperature again.
