12V GURU | How Much Power Do You Actually Need?
How much power does your caravan really need? The 12V Guru explains how the appliances you use and the time you spend off-grid determine the right power solution for the way you travel.
Following extensive testing across three independent Australian facilities, BMPRO ProBoost has been selected by Ford for the Ranger Super Duty and Mazda for the BT-50 platform, in recognition of its proven performance, durability and reliability in demanding real-world conditions.
Engineered for extreme under-bonnet environments, ProBoost combines advanced DC-DC charging with integrated MPPT solar capability. It continues to operate and deliver charge at sustained temperatures of 80°C. Testing pushed ProBoost even further, operating faultlessly at 95°C for 92 hours, well beyond typical automotive conditions.
At the opposite end of the temperature range, it delivered dependable performance down to -40°C, demonstrating reliability in even the harshest cold environments.
Built for Real Conditions
Built to true automotive standards, ProBoost has also been validated to IEC 60068-2-64 vibration testing and subjected to substantial mechanical shock testing, confirming its ability to withstand constant movement, rough terrain and severe operating conditions.
This is more than laboratory validation. It is real-world performance proven across extreme heat, cold, vibration and shock – and a clear reason ProBoost has been selected for leading Ford and Mazda automotive applications.
ENGINEERED BEYOND THE SPEC. PROVEN IN THE REAL WORLD.

How much power does your caravan really need? The 12V Guru explains how the appliances you use and the time you spend off-grid determine the right power solution for the way you travel.

As more caravan owners upgrade to lithium batteries and spend longer off-grid, expanding an existing power system has never been easier. Discover how the BMPRO ecosystem lets you seamlessly integrate chargers, battery monitoring and power management into one connected system for smarter charging, better visibility and reliable off-grid performance.

For more than four years, BMPRO has proudly supported the Idlers 4WD Club through regular education sessions focused on 12V power systems, battery management, and the rapidly changing world of lithium technology.
