ProMariner Battery Chargers, Invertors & Isolators

Professional Mariner was founded over 40 years ago with one premise; to make boating more enjoyable! We pioneered a robust line of fully automatic, on-board marine battery chargers that provided the marine industry with a mainstream method of charging batteries in a short time without the need for storing or carrying portable battery chargers on-board. We haven't looked back since.
