True Blue Power CHRONOS Digital Clock

Single and Dual USB Configuration 6420093 Chronos Series Digital Clock

Replace aging analog or limited-function digital clocks with the Mid-Continent CHRONOS Series Digital Clock and USB Charger. Combining a bright six-digit, seven-segment LED display with up to 8 operational modes and up to 75 watts of integrated USB charging power, the CHRONOS fits a standard 2¼-inch panel cutout and installs easily as a direct upgrade in virtually any cockpit. Models range from a clock-only unit to the CH93MAX with dual USB-A and USB-C PD ports.

All USB charging ports employ intelligent voltage negotiation for the fastest possible charge speeds. Designed with enhanced cybersecurity protocols, meaning no data is transferred between the unit and any connected device or aircraft system.

STCs are available for a wide range of aircraft. Certified to FAA-TSO C71, EASA-ETSO C71, and RTCA DO-160G.
