There was some discussion about Powerlet power plugs awhile back. I just happened to find some interesting info due to a question on FB. According to a filing made on Nov 20, 2018 with the Michigan Department of Licensing and Regulatory Affairs, John A. Swiatek, the owner of Coliant Corporation filed a termination of two business names he has been using. One is Powersport Electric and the other is Powerlet. Here are links to the documents.

Revzilla has all their Powerlet products on closeout. Be careful. The Powerlet web site is still running. I think it might be on autopilot and will process charges without anyone actually fulfilling orders.
