Protect and power your onboard electronics with precision using DC to DC converters from The Outdoor Warehouse. These converters safely transform voltage between battery banks — ideal for boats with multiple electrical systems, solar setups, or lithium upgrades. We carry trusted brands like Victron Energy, ProMariner, Blue Sea Systems, and Mastervolt, built for marine reliability, vibration resistance, and high-efficiency performance in any environment.
What Does a Marine DC to DC Converter Do?
A DC to DC converter regulates voltage between two direct-current power sources, ensuring your 12V, 24V, or 48V systems operate safely and efficiently. Marine applications often require converters to balance loads between starting and house batteries, charge auxiliary systems, or power sensitive electronics from stable voltage output.
- Voltage Step-Down: Converts 24V to 12V for electronics like radios, lights, or navigation systems.
- Voltage Step-Up: Converts 12V to 24V for thrusters, pumps, or specialty equipment.
- Battery Charging: Charges a secondary battery bank without isolator losses.
- Voltage Regulation: Provides clean, filtered output to protect electronics from spikes.
Popular Marine DC to DC Converter Types
| Converter Type | Best For | Key Features |
|---|---|---|
| Step-Down (Buck) | 24V to 12V conversions | Compact size, efficient output, overload protection |
| Step-Up (Boost) | 12V to 24V or 48V systems | High current stability, thermal protection |
| Isolated DC to DC Chargers | Charging separate battery banks | Prevents ground loops, ideal for lithium/AGM systems |
| Non-Isolated Converters | Single battery system loads | Higher efficiency, smaller form factor |
| Smart Multi-Stage Chargers | Modern solar or alternator-based setups | Bluetooth monitoring, automatic voltage detection |
How to Choose the Right DC to DC Converter
- Voltage Compatibility: Match the converter to your system (12V, 24V, or 48V).
- Load Rating: Choose a converter rated for at least 25% above your expected current draw.
- Isolation: Select an isolated model when charging secondary battery banks or preventing interference.
- Marine Protection: Look for IP67 sealing, ignition protection, and corrosion resistance for marine use.
- Smart Features: Consider models with temperature sensors, Bluetooth control, or programmable output.
Pro Tip
Pair your DC to DC converter with a battery management system and solar panel setup for optimal charging efficiency. For complete off-grid reliability, explore our marine inverters and fuse blocks for full system protection.

Frequently Asked Questions
What’s the difference between a DC to DC converter and a battery charger?
A DC to DC converter changes voltage between systems, while a DC to DC charger safely recharges a secondary battery bank using a regulated charge profile.
Can I use a DC to DC converter with lithium batteries?
Yes. Many modern converters and chargers (like Victron Orion-Tr Smart) include adjustable voltage settings for lithium (LiFePO₄) batteries.
Do I need an isolated converter?
Isolated converters are recommended when charging multiple battery banks or when electrical noise and interference are a concern.
Can DC to DC converters work with solar panels?
Absolutely — they’re often used in conjunction with MPPT solar controllers to regulate or distribute voltage between battery systems.
