While departing ZZZ1 for a direct flight to ZZZ2; I inadvertently climbed into ZZZ Class C airspace while heading 280. My plan called for climbing to 3;500 feet for the short flight.  I completely forgot about the Class C airspace floor.  Contributing Factors include:- Not being VFR current due to winter weather; Coronavirus limitations.- The autopilot on the plane was placarded 'INOP'.  I typically set the altitude on the autopilot to 2;000 feet (100 feet below the floor) as a reminder for the airspace floor.- Air temperature was -X degrees C; which makes for great airplane climb performance.  The last time I had flown was October; and the weather was much warmer.  I was distracted by the great visibility and great climb rate.- This plane is part of a local flying club.  Planes are at X different local airports; only one of which is under the Class C veil.  It's sometimes hard to remember all the different nuances when you are flying different planes from different airports; and don't do it regularly.- I sometimes fly IFR.  This provides additional protection from this type of excursion because you are talking to ATC continuously.I just have to be more focused about airspace limitations when flying VFR from this airport.
GA pilot reported entering Class C airspace without clearance.
