Narrative:

After an uneventful flight from to ZZZ immediately beforehand; I picked up passengers at ZZZ.on initial climb out; I lost alternator power. Digital display on panel indicated the problem; but I did not immediately recognize it for what it was. I knew something wasn't right with the electrical system; and suspected that I had lost the alternator but was unsure. Kept an eye on instrument and saw continued negative draw on battery; and voltage dropping; and determined I had a problem.I reported the problem to ATC; canceled my flight plan; and stated my intent to return immediately to ZZZ. I believe I was on with approach at the time. They asked if I wanted flight following; I said yes; and said I would likely lose my radios soon. By that time the panel was dimming significantly. ATC asked if I needed anything else; and I asked them to get the lights on at ZZZ; and they confirmed my request.as I was on with ATC; I was executing a 180 turn. Shortly after ATC confirmed my request for lights; I lost all power. I was able to use my phone; which has foreflight + GPS; to navigate to ZZZ; which was a much easier option than a dark compass. The runway lights were on (I would learn later they were activated by a nearby aircraft at the request of ATC) and I was able to manually extend the gear per memorized procedure; and successfully landed at ZZZ.ATC had the local fire and police department waiting for me at ZZZ; for which I'm grateful; despite not needing them in the end.things I did well:- noticed the problem- stayed calm- took action and told ATC what I needed- prepared plan B and C in my mind if plan a didn't work out (plan B - call police to get runway lights turned on; plan C - fly to towered airport nearby)- had a backup nav system ready to go; and used itthings that I did not do well / will do differently:- understand my digital display and electric system completely so that I recognize problems instantly- in the event of an alternator problem; immediately slow to gear extension speed and extend gear; and turn off all unnecessary electrical items- practice with and carry a portable radio on all flights
