About AMP'D 12V
AMP'D 12V is an independent Australian 12V planning website built to help 4WD, camper and caravan owners size batteries, solar, DC-DC chargers and inverters before spending money.
Who is behind AMP'D 12V?
AMP'D 12V was built by Jarrod, a South Australian 4WD camper with years of hands-on experience running fridges, AGM and lithium batteries, roof solar, DC-DC chargers and inverter appliances while touring. It is an independent project, not a battery retailer or electrical installation business.
What AMP'D 12V does
The free calculator turns the appliances you carry, how long you camp, how much you drive and the conditions you expect into practical battery, solar, DC-DC charger and inverter sizing guidance.
Why it exists
12V advice is often scattered across product pages, forums and sales material. AMP'D 12V brings the important calculations into one transparent, brand-neutral starting point so Australian travellers can understand what they need instead of simply buying the largest system.
How recommendations are made
Recommendations are based on estimated daily energy use, usable battery capacity, available charging time, seasonal solar conditions and equipment limits. The assumptions and formulas are published on the How it works page, and estimates should always be checked against exact manufacturer specifications.
Real Australian touring focus
The calculator is designed around common Australian 4WD, camper and caravan use, including hot-weather fridge loads, seasonal solar, shade, driving time and product sizes commonly sold in Australia.
Independent and brand-neutral
The calculator recommends system specifications rather than a particular brand. Some pages contain clearly disclosed affiliate links, but those relationships do not change the calculator's sizing logic or results.
