12V to 48V DC-DC Converter
Modern hybrid boats increasingly run on 48V systems. When the onboard source remains 12V, a reliable step-up booster is needed to deliver stable 48V power for modern marine equipment.
This converter boosts a 12V battery input to regulated 48V DC in a compact, waterproof, marine-ready format. It is designed for clean integration into hybrid boats, onboard electronics, network equipment, and other 48V marine installations where stability and efficiency matter.
The model to put forward is the 10A / 560W version. It is the most powerful version in the range and the strongest choice for installations that need more capacity, more reserve, and more confidence than entry-level converters can offer.
Made for Modern 48V Hybrid Boats
As 48V becomes standard across modern hybrid and electric boat architecture, a step-up converter becomes essential whenever part of the system still relies on 12V. This unit gives you a practical and efficient bridge between those two voltage levels without rebuilding the entire electrical installation.
The 560W model should lead the page, the images, and the ads. It instantly positions the product as a serious marine power solution, not a small accessory converter.

Best Applications
Hybrid boat electrical systems
Add stable 48V power to an existing 12V setup without a full electrical rebuild.
Starlink and 48V PoE equipment
Power compatible routers, antennas, access points, switches, and connected network devices.
Onboard electronics
Support marine communication, networking, and control systems that require regulated 48V DC.
Higher-demand 48V loads
The 560W version gives more reserve for installations where smaller converters are not enough.
Simple Wiring
- 🔴 Red: Positive input (12V +)
- ⚫ Black: Negative input (12V - / ground)
- ⚫ Black: Negative output (48V -)
- 🟡 Yellow: Positive output (48V +)
- This is a 12V to 48V DC-DC step-up converter for powering compatible 48V equipment from a 12V source.
- It is not a battery charger for 48V battery banks.
- Please confirm that your device accepts 48V DC input before installation.
- For more demanding systems, the 10A / 560W model is the recommended choice.
