How Much Power Do You Actually Need in a Camper Van?
Power is the most misunderstood system in a camper van. Most people either underbuild it and regret it, or overbuild it without understanding why.
Here’s how we think about power.
Start with how you live
Power planning starts with questions, not batteries.
Do you want air conditioning?
Do you work remotely full-time?
Do you cook with electricity?
These answers determine everything else.
The stacking effect
No single component drives cost on its own.
Solar requires a roof rack.
Roof racks require proper mounting and waterproofing.
Solar needs charge controllers.
Alternator charging requires heavy-gauge wiring.
It’s all connected.
Minimums matter
Once air conditioning enters the conversation, we recommend a minimum of 540Ah of battery capacity. Anything less drains too quickly to be practical.
Bigger is not always better, but undersizing almost always leads to frustration.
Common mistakes
Planning for average days instead of worst-case days
Ignoring charging sources beyond solar
Designing power after the layout is finalized
Our approach
We design power systems based on use, not trends. The goal is reliability, not spec sheet bragging rights.
A good power system fades into the background. A bad one runs your life.
