Narrative

Approaching ZZZZZ 7000 feet and commending turn to ZZZ [VOR] (as filed); the plane suffered complete electric and communication failure. Result was no radios; navaids; transponder; and lights. I continued as filed and as I approached ZZZ [airport] I descended to ZZZZ1 and descended to 3000 feet. At ZZZZ1; I entered the hold and tried to get use cell phones to contact TRACOM/ATC to no avail.After a turn in the holding pattern; I proceeded to ZZZZ2 for an approach to ZZZZ2 for an approach to RWY XX. Approaching ZZZZ3; we finally had a successful cell phone contact with the airport and I was able to [request priority handling] officially.On the initial approach we went around; realizing that I could not verify that the nose wheel was down due to lack of electrical power and LG (Landing Gear) indicating lights. We communicated with ground personnel for a low pass to verify LG extension. Ground personnel reported that the LG did not look locked in place. I climbed to TPA and commenced to use the Checklist for emergency landing gear extension and executed another low approach an confirmed that the LG appeared to now be locked in place. I maneuvered for another approach and landed without further incident.After securing the aircraft; I reported to the airport manager and called TRACON to verify that we were down and safe and to confirm in any further action was required on my part.Side note: I did receive phone calls intermittently after power loss. I could hear TRACON; however; they could not hear me.
