What was found
DISCREPANCY: SMOKE IN CABIN. ARRIVED AT AIRCRAFT, MEDICAL STAFF INFORMED ME THE SMOKE HAD COME OUT OF PORTABLE POWER STRIP/ SURGE PROTECTOR 8 SOCKET 115VAC OUTLET EXTENDER. DURING FLIGHT PILOT TURNED OFF POWER TO LIFEPORT BED AND SMOKE STOPPED COMING OUT OF UNIT. I REMOVED THE UNIT FROM THE AIRCRAFT AND NOTICED IT WAS VERY WET AS IF SOMETHING WAS SPILLED INTO THE UNIT AND IT SMELLED OF ELECTRICAL BURN. I WENT TO WALMART AND BOUGHT ANOTHER OUTLET STRIP AND GAVE TO MEDICAL STAFF. NO FURTHER ACTION TAKEN.
