A multimeter is essential for van life. It tests voltage, current, and resistance in your 12V system. Without one, diagnosing electrical problems is guesswork.

Why You Need One
- Test battery voltage: Know when your battery needs charging
- Check solar panel output: Verify your panels are working
- Diagnose wiring problems: Find loose connections and short circuits
- Test fuses: Check if a fuse is blown
- Measure current: See how much power your devices are drawing
What to Look For
- Auto-ranging: Automatically selects the right range
- True RMS: More accurate for AC measurements
- Backlit display: Readable in dark vans
- Durable: Drop-proof, water-resistant
- Safety rated: CAT III or CAT IV rated
How to Use It
Test Battery Voltage
- Set multimeter to DC voltage (V⎓)
- Touch red probe to positive terminal, black to negative
- Read the voltage: 12.6V+ = full, 12.4V = 75%, 12.2V = 50%
Test Solar Panels
- Set multimeter to DC voltage
- Touch probes to panel output cables
- Read the voltage: should match panel rating
Test Fuses
- Set multimeter to continuity (beep symbol)
- Touch probes to both ends of the fuse
- If it beeps, the fuse is good. If not, it's blown.
Conclusion
A multimeter is essential for van life. The UNI-T UT33D+ (£15) is the best budget option. The Fluke 101 (£60) is the best mid-range. Either way, you'll use it constantly.
