10 Wackiest USB Gadgets
Dual-Heated Travel Mug ($14.99)
Work days are long and coffee gets cold. How do you fix that? With a USB-heated travel mug that keeps all 16 ounces of your morning joe at optimal temperatures well into the afternoon (it also works via car charger). The spill-proof lid should protect against splashes on your dashboard or laptop computer, but, for the love of the Starbucks mermaid, don’t put this mug in a dishwasher.
