My Recommended EquipmentVan & RV Builds
After analyzing hundreds of builds and months of real-world testing, here is the gear I genuinely recommend. Every product was selected for value, reliability, and compatibility with 12V vanlife systems. Buying through my links supports VanPowerCalc at no extra cost to you.
LiFePO4 Batteries
LiFePO4 is the gold standard for van builds. 3x lighter than AGM, 80% usable depth of discharge (vs 50% for AGM), and 3000+ life cycles. Look for at least 100Ah for regular use, 200Ah+ if you run a fridge and work remotely.
LiFePO4 Battery 100Ah
100% usable capacity, 3000+ cycles, built-in BMS.
~USD 250-600
Solar
An MPPT solar kit is the best investment for off-grid autonomy. The MPPT (Maximum Power Point Tracking) controller optimizes conversion and harvests up to 30% more energy than PWM. Aim for 200W minimum solo, 400W+ for a couple with a fridge.
Complete 200W Solar Kit
Panel + MPPT controller + cables, ready to install.
~USD 200-500
Victron MPPT Controller 100/30
Extracts 97% solar power, Li & AGM compatible.
~USD 50-150
Alternator Charging
A DC-DC charger is essential for Euro 6+ vehicles. It replaces the old split-charge relay system by intelligently regulating voltage. It charges your leisure battery while driving, even with a smart alternator.
Victron Orion DC-DC Charger 30A
Charges battery from alternator with correct Li profile.
~USD 150-350
230V Inverter
A pure sine wave inverter is essential for sensitive 230V devices (laptop, drone charger, CPAP). Pure sine replicates mains power quality. Size it at 150% of your peak AC consumption.
Pure Sine Wave Inverter 1000W
Pure sine wave, sensitive devices compatible, 12V→110V/230V.
~USD 100-400
Wiring & Safety
Clean, secure wiring is the foundation of a reliable install. A good multimeter, quality crimping tool, and heat shrink tubing prevent 90% of electrical issues in vans.
Digital Multimeter
Measures voltage, current, resistance — essential for 12V wiring.
~USD 30-80
Electrical Crimping Tool
Reliable crimp connections on 0.5mm²–16mm² cables, no soldering.
~USD 25-50
12V Appliances
A 12V compressor fridge is the ultimate vanlife upgrade. Unlike thermoelectric coolers, it maintains true fridge temps (2-8°C) even in 35°C heat, and uses less power.
12V Compressor Fridge
Portable 12V/24V compressor fridge for vans and RVs — low power, quiet operation.
~USD 300-800
