USB Mug Warmer

Is it worth it?

I have googled reviews that the usb power cap is not enough to heat the mug to a warm temperature.

Anyone know where sells it? I have went to several places today to no avail.

Your help is appreciated.

Thanks for moving this thread. Didn't exactly know where to put it.
