The high-power USB charger delivers three amps per port—even when both ports are in use—to simultaneously charge electronic flight bags, cell phones, tablets, and other electronic devices at full power. The unit’s compact, two-inch design allows it to conveniently fit in any standard panel cutout.

Mid-Continent Instruments President and CEO Todd Winter said the clock marks an improvement of an earlier design. “We’ve had it out for a couple years. What we did was up the power,” he said. “We custom build the circuitry in these clocks in Wichita.”

The six-digit, seven-segment LED clock provides easy operation with multiple modes: local time, UTC/Zulu time, countdown timer, and stopwatch. An internal battery, with a life expectancy of more than 10 years, maintains time and flight timer memory when power is not received from the aircraft. Additional features include external lighting control and a built-in photocell for automatic dimming. The MD93H protects itself and the charging device from short circuit, power surges, and over-current potential.

The MD93H Digital Clock/USB Charger has a list price of $684.
