Emergency battery chargers for marine electrical systems provide backup power to critical equipment during outages. They ensure continuous operation of navigation, communication, and safety devices. Designed for harsh marine environments, they are compact, waterproof, and corrosion-resistant.

Size: Compact, typically 10-30 cm in length, 5-15 cm in width, 5-10 cm in height.

Grade: Marine-grade, IP67 or higher for water and dust resistance.

Viscosity: Not applicable (N/A) as it is an electrical device.

Buoyancy: Designed to float if dropped in water, buoyancy varies by model.

Material: High-impact ABS plastic, corrosion-resistant metals, and waterproof seals.

Voltage Output: 12V or 24V DC, compatible with marine batteries.

Current Output: 5A to 30A, depending on model.

Charging Ports: USB, alligator clips, or direct wiring connections.

Weight: 0.5 kg to 2 kg, lightweight for portability.

Operating Temperature: -20°C to 60°C (-4°F to 140°F).

Safety Features: Overcharge protection, short-circuit protection, reverse polarity protection.

Certifications: CE, RoHS, and marine safety standards (e.g., ISO 8846).

Emergency Battery Chargers and Marine Electrical products typically comply with maritime standards such as IEC 60945, ISO 8846, and ABS/CE/UL marine certifications. Always verify specific product certifications with the manufacturer.
