The 12-volt Smart Car Hot Pot heats up to 20 oz. of tea, soup or hot chocolate in just minutes, the company says. It auto detects when liquid level is too low and automatically shuts down to prevent damage. The canister detaches for pouring and cleaning and the lid snaps securely to prevent spills while on the road. The Smart Car Hot Pot also includes a mounting bracket and is available at 12-volttravel.com for less than $20.
