Blue Sea 1045 Dual USB Charger (4.8A): Fast, Reliable USB Power for Marine & Mobile Systems

Modern electrical systems demand more than basic power delivery — they require reliability, protection, and clean performance across every connection point. As part of the trusted Blue Sea Systems ecosystem, the Blue Sea 1045 Dual USB Charger – 4.8A is engineered to provide fast, stable USB charging in marine, RV, and mobile environments where durability matters.

Designed to integrate seamlessly with professional-grade DC systems, this charger complements installations built around Blue Sea Systems power distribution components while maintaining a compact, low-profile footprint.

Fast, Device-Optimized USB Charging

The Blue Sea 1045 delivers up to 4.8 amps of combined output, automatically charging devices at the speed they require. This makes it ideal for powering:

• Smartphones and tablets
• GPS units and navigation accessories
• Handheld radios and portable electronics

Because it’s designed for clean DC environments, it performs reliably even when installed near a Blue Sea fuse block or other sensitive power distribution hardware.

Reduced Electrical Noise & System Interference

Internal filtering minimizes electronic interference, helping maintain stable performance across connected electronics. This is especially important in systems where USB power is installed alongside radios, monitoring equipment, or circuits tied into a Blue Sea bus bar.

The result is consistent charging without introducing unwanted noise into the broader electrical system.

Built for Harsh Marine & Mobile Environments

True to Blue Sea’s reputation, the 1045 USB charger is built for real-world conditions:

• Fully potted electronics for moisture resistance
• Over-temperature protection for long-term reliability
• Protective dust cap to keep debris and water out

These features make it suitable for boats, RVs, overland rigs, and fleet vehicles exposed to vibration, humidity, and temperature swings.

Simple, Clean Installation

The charger mounts into a standard 1-1/8″ panel hole, making it easy to add to dashboards, control panels, or DC distribution areas without custom fabrication.
