Non-isolated DC-DC Chargers

Non-isolated models share a common negative between input and output. They are compact and work well when both batteries are in the same vehicle.

The model name lists input voltage, output voltage and current. A 12/12-30 takes 12 V in and gives 12 V out at up to 30 A.

• Choose the input voltage that matches your source battery.
• Choose the output that matches the battery you are charging.
• Pick a current that fits your battery size.
