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. Today, ProMariner is the industry leader in marine and mobile battery charging. We have a complete line of waterproof and dry-mount chargers for all battery chemistries, as well as technically advanced power conversion modules. All of our products are designed to prolong the life of your batteries, and keep you on the water longer.
