Guardian Avionics has unveiled a $299 USB power port that fits into the hole created for cigarette lighter sockets found in many aircraft. The new Power 250-101R Dual 2.1-Amp USB Power Supply is listed under a Guardian Avionics non-required safety enhancing equipment letter of authorization issued by the FAA and thus can be installed by an A&P mechanic as a minor alteration. No STC or Form 337 is required for installation in Part 23 airplanes and Part 27 and 29 rotorcraft.
