Detailed description

Designed for fast charging of mobile devices on board, the BLUE SEA 4.8A dual USB 12/24V DC charger (reference 1045) features smart device recognition. This function adjusts the charging current to match the specifications of each device, whether phones, tablets or other USB 2.0 Type A compatible devices, with a maximum total output of 4.8A DC at 5V DC ±5%.

Marine Design and Built-in Protections

This charger is specifically adapted to the marine environment thanks to a printed circuit board coated with a conformal coating to protect against corrosion and moisture. Internal filtering is also included to minimize electronic interference with other onboard systems. The unit includes full protection against overheating, short circuits, and reverse polarity, ensuring the safety of the installation and connected devices. A protective cap keeps the port clear of debris and moisture when not in use. Its standby parasitic current is only 1 mA, optimizing onboard power consumption.

Positioning and Installation

The 1045 model features a "socket" mounting type (flush-mount), requiring a standard 1-1/8" (29 mm) diameter cutout. It uses 0.250" (6.35 mm) quick-connect input terminals for simplified installation. Within the BLUE SEA USB charger range, it sits alongside the 1039 model, which offers the same technical specifications (12/24V, 4.8A, smart recognition) but is designed for mounting in a Contura switch-style cutout. These models differ from the 48V chargers (1038 and 1046), which are specifically dedicated to 48V systems and provide a total output of 4A. The 1045 charger is RoHS and CE certified.

« Blue Sea 1045 dual USB charger: reliability and marine integration »

The BLUE SEA 1045 dual USB charger is a reliable and discreet power solution for personal devices aboard recreational or utility vessels. Its 12/24V DC compatibility makes it universal for most standard marine installations, avoiding the complexity of additional voltage converters. The key advantage of this model lies in its intelligent device recognition function, which ensures optimized charging without risk of overcharging or underpowering, thereby extending the battery life of your devices.

Its flush-mount installation in a 29 mm diameter hole is an industry standard, facilitating integration into existing dashboards or new builds. The 0.250" quick-connect terminals simplify wiring significantly, even for the most compact installations. Compared to the 1039 model in the same range, the 1045 is preferred for locations requiring a round finish, whether for aesthetic or practical reasons depending on the helm or cabin layout. The low standby current draw of 1 mA is a critical feature for standalone installations where every milliamp counts, minimizing discharge of the vessel’s battery when the charger is not actively in use. Note that this charger is ideal for standard USB-A devices but does not support fast-charging protocols such as USB-C Power Delivery.
