Reliable Dual 2.7 Amp USB Power in your Panel

The smartPower 250-101 is a cockpit flush mounted single USB-A/dual charging unit designed to provide reliable power for most consumer products with USB charge capabilities such as smartphones and tablets. The smartPower 250-101 simultaneously provides 2.7 amps at 5 VDC ± 0.25 (12 watt) for each USB port / connection. The small, unobtrusive design requiring only a 0.785 inch square cutout in the panel to be mounted. The 250-101 features green LED backlit ports for easier use in night flying conditions.

Available in two faceplate styles: a custom square faceplate or a round faceplate style that fits all standard openings for 12V cigarette lighter socket panel cuts.

The smartPower 250-101 features a feedback loop to keep the 2.7 amp current stable for each port at all times. The units are EMI shielded and also feature reverse polarity protection.
