Van Life 12V Power Use: What Daily Electrical Consumption & Recharge Really Looks Like on the Road

If you're planning a DIY van build or designing your electrical system, you’ve probably asked: How much power will I actually use in a day? In this video, we break down our real-life 12V electrical usage and how our system recharges during an average day on the road—so you can plan your van’s power setup with confidence.

This is a van life reality check for anyone designing a solar setup, wiring a 12V system, or trying to figure out how much battery capacity they actually need. We cover how our system performs under real conditions—charging phones and laptops, running a 12V fridge, lights, fans, and more—plus how our power bank recharges from solar, alternator, and shore power.

We don’t just talk specs—we show you actual usage data, daily charge levels, and how to avoid draining your system unexpectedly. Whether you're building for full-time van life or weekend adventures, this video gives you the insight you need to size your system right.

In this video, you'll learn:

How much power we use daily on our 12V setup

Which appliances and devices consume the most energy

How our solar panels and DC-DC charger keep our batteries topped up

How weather and driving habits affect battery recharge rates

Mistakes to avoid when sizing your battery bank and solar array

Tips for monitoring your system and staying off-grid longer

This video is ideal for anyone designing a DIY 12V system using lithium or AGM batteries, solar charge controllers, DC-DC chargers, and 12V appliances. Whether you’re running a basic setup or a full off-grid electrical system, understanding daily power flow is key to a successful van life experience.

Great for:

DIY van builders planning 12V electrical systems

Van life designers calculating daily energy needs

Full-time or weekend travelers wanting off-grid reliability

Builders using Battle Born, Renogy, Victron, or EcoFlow components

We’re sharing our real-world data from months of full-time travel—what worked, what didn’t, and how you can dial in your system to fit your unique lifestyle on the road.

At Van Of Action we are sharing the van life / nomad experience. Most folks who are designing a van build and dreaming of vanlife have never done either before. There are so many parts to every van build and so many different ways to use the vancamper when it’s complete. Some will be day and weekend campers, some will be overlanders and some will be nomads living full time off grid making their vans really tiny homes. In every case there will be different requirements, but some things will be the same. One of the biggest questions is about van electricity. Howe much do I need ? How much will I use ? How fast can it charge ? In this video Van Of Action shares our electrical usage over a 24 hour period on a typical day driving. Our van 12 volt system uses Renogy components – solar panels https://ca.renogy.com/products/solar-..., Charge controller https://ca.renogy.com/products/charge..., inverter https://ca.renogy.com/products/invert... and batteries https://ca.renogy.com/products/deep-c... - we also have a DC-DC charging capability but didn’t need it. We had our lithium batteries completely charged at as the sun went down on day one. After dark we powered our cabin lights and max air fan = https://www.maxxair.com/ and dometic CFX3 95 DZ dual zone fridge freezer. The next day we made breakfast and spent the day as we normally would – being nomads on the road. By the end of the day our batteries were completely recharged.
