Dolphin Charger

What Dolphin Charger does

Dolphin Charger, the commercial trade name of CATS POWER DESIGN, is a French privately held company (SARL) headquartered in Annecy at 2 chemin de Branchy, France. Founded in 1996 and operating as a member of the Eight Lakes group, the company designs, manufactures, and distributes marine power conversion equipment for recreational boating, commercial and military maritime, recreational vehicles, professional vehicles, and industrial bodywork converters. It is small (11–50 employees) and self-funded, with no disclosed venture capital, institutional investment, or public listing. Operations are concentrated at the Annecy site, which serves as headquarters and primary manufacturing location.

The product portfolio centers on AC/DC battery chargers across four series: the Premium Plug&Play line (10A–60A) for coastal sailing and yachting, the Pro Touch line (40A–150A) for yachts, superyachts, commercial and military vessels and offshore platforms, the DNV-GL Marine Type Approved Pro HD+ line (40A–100A), and the compact, fan-less, ignition-protected (ISO 8846) PROLITE line (15A–40A) at 92% efficiency. The company also produces DC/DC boosters including a European-patented Double Output DC/DC Booster designed for Euro 6/7 alternators (ECE R10 E-marked), PRO and AGM/GEL batteries (AGM/GEL supplied via an 80+ country partner and DNV-GL approved), battery monitors (BATVIEW, TOUCHVIEW with CANBus), a leakage monitor for electrolytic corrosion, automatic charge selectors (ACS) using MOSFET technology, and the Dolphin Connect Bluetooth mobile app. Core engineering differentiators are proprietary MOSFET-based battery isolation with current limiting and blocking-diode functions, 4-stage intelligent charging programs covering Lead, Gel, AGM, Lithium, and LiFeSO4 chemistries, and ruggedized enclosure design (IP65/IP67) tuned for marine and harsh-vehicle environments.

The business model is multi-channel hardware sales plus custom engineering services. Revenue streams comprise battery chargers and power supplies, DC/DC boosters and inverters, batteries, monitoring and control devices, OEM/ODM custom power solutions (standard, semi-custom, and full-custom), and accessories. Go-to-market combines direct OEM/white-label partnerships with boat builders, vehicle manufacturers, and industrial bodywork converters; dealer and reseller networks including AD Nautic (150+ stores globally) and Uship retail in France and Europe; professional marine electricians and installers for refit and new build; and direct sales via the company website. Pricing is unit-based at retail (Premium from approximately €249, PROLITE around €299, ALL-IN-ONE around €659), with quotation-based pricing for professional and OEM customers. There is no software-as-a-service, subscription, or licensing revenue component disclosed.

Direct peers

• Balmar: US-based manufacturer of marine charging alternators and battery charging solutions, including multi-stage regulators and DC charging systems. Adjacent in category (alternator-based charging vs Dolphin Charger's AC mains and DC/DC chargers) but competing for the same vessel power management wallet.
• Mastervolt: Marine and mobile power conversion specialist offering battery chargers, inverters, and lithium-ion systems integrated via the CZone digital switching platform. Competes head-to-head with Dolphin Charger's Pro Touch/Pro HD+ and ALL-IN-ONE offerings in the yacht, superyacht, and commercial marine segments.
• Quick SpA: Italian manufacturer of marine electrical equipment including battery chargers, inverters, and charging systems for yachts and superyachts. Direct overlap with Dolphin Charger's Premium/Pro Touch lines across Mediterranean OEM accounts and dealer networks.
• Victron Energy: Netherlands-based specialist in marine, mobile, and off-grid power conversion (inverter/chargers, battery chargers, DC/DC converters, monitoring). Directly competes with Dolphin Charger across the same marine battery charger and DC/DC booster categories, and shares a strong OEM and dealer-distribution model in Europe.
• Sterling Power Products: UK-based manufacturer of marine battery chargers, alternators-to-battery chargers (essentially DC/DC boosters), and battery-to-battery chargers. Direct overlap with Dolphin Charger's BOOSTER Series and Double Output DC/DC Booster, particularly in the UK and Northern European marine and RV markets.
• CRISTEC: France-based specialist in marine and industrial battery chargers, sharing Dolphin Charger's home market. Competes on similar power ranges, ignition protection, and OEM supply to French and Southern European boat builders, making it a closely comparable French specialty manufacturer.
• ProMariner: US marine battery charger specialist serving recreational boats, yachts, and pro fishing applications with onboard chargers and waterproof designs. Closely comparable to Dolphin Charger's PROLITE and Premium Series in form factor, IP rating focus, and target boater profile.
• Newmar Power Systems: US-based manufacturer of marine and mobile DC power products including battery chargers, DC/DC converters, and power conditioning. Overlaps with Dolphin Charger's product lines in the yacht, workboat, and OEM marine segments, particularly for the North American market Dolphin Charger currently under-indexes in.

Broad incumbents

• Marinco (Dometic Group): Marine electrical brand within Dometic's broader mobile power portfolio, covering shore power, battery chargers, and onboard power accessories. Larger incumbent with broader catalog but overlapping charger and power conversion offerings for recreational and small commercial marine customers.
• Xantrex (Schneider Electric): Marine and mobile power conversion brand under Schneider Electric, offering inverter/chargers, chargers, and monitoring for recreational and commercial marine. A much broader incumbent with greater resources but similar core products to Dolphin Charger's marine charger and inverter/charger range.
