Additionally, coffee contains caffeine, which can enhance alertness and attention, helping to improve productivity and focus.

The BUNN CSB3T Speed Brew Platinum Thermal Coffee Maker runs on a standard 110V power supply. It does not have a battery or portable operation. The hot tank draws continuous power to keep water heated.
