12V to 15V DC-DC Converter

A lot of converters look almost identical from the outside, but what’s inside can be a very different story. Cheap converters can have poor voltage regulation or protection, which can potentially send an incorrect output voltage to your accessories if something goes wrong.

For that reason, we prefer using quality converters where reliable voltage regulation actually matters.

12V to 15V Converter

Our most popular option is the 12V to 15V DC-DC converter.

It boosts the voltage available from a typical 12V battery system up to a regulated 15V at the accessory.

This is particularly useful for higher-current accessories such as:

- Travel Buddy ovens

- Heated seats

- Electric windows

- Small motors

- Other suitable 12V resistive loads

Mounting the converter close to the accessory can also help compensate for voltage drop through the supply cable, giving the device a consistent voltage even when the battery voltage is lower.

Why Does a Few Extra Volts Make Such a Difference?

With a simple resistive load such as a heater, power is approximately proportional to voltage squared.

For example, increasing the voltage from 12V to 15V can theoretically increase the power of the same resistive load by around 56%.

The actual change depends on the device. Motors and electronically controlled equipment do not necessarily behave like a simple resistive load.

Most automotive equipment is designed to operate across a range of voltages because a running vehicle can typically supply considerably more than 12V. However, 15V may still be outside the rated operating voltage of some equipment.

Always check the voltage rating of the device before using a step-up converter.

12V to 16V Converter

We also offer 12V to 16V step-up converters.

16V provides an even larger increase in available voltage and can substantially increase the power delivered to suitable loads.

This should only be used where you understand the electrical characteristics and voltage limits of the equipment being powered.

Running equipment above its rated voltage can damage the device, wiring or associated components.

Not Suitable for Battery Charging

Do not use these converters to charge a battery.

Lithium, AGM and other rechargeable batteries require a proper DC-DC battery charger with the correct charging algorithm, voltage limits and charging stages.

These converters are designed to supply suitable electrical accessories — not to replace a battery charger.
