Backup for Campervans
Run fridge, lights, laptop, phones and comfort loads with portable power that can recharge from solar, wall or vehicle charging.
Problem to solve
- Travel loads are small individually but run for long periods.
- Fridge duty cycle, weather and solar exposure change real autonomy.
- Cooking, kettle, heater and induction loads need much larger output and careful planning.
Typical consumption
| Load | Typical watts | Planning note |
|---|---|---|
| 12V fridge | 40-80W average | Continuous cycle |
| LED lights | 10-40W | Evening use |
| Laptop | 60-100W | Work / entertainment |
| Phones/tablets | 10-40W | Small |
| Water pump | 40-120W | Intermittent |
| Induction / kettle | 1000-2000W | Short high peak |
AutonomÃa
| Level | Load range | What it covers | Recommended solution | AutonomÃa |
|---|---|---|---|---|
| Weekend Light | 120-250W mixed | Fridge, lights, phones | 1 kWh station class | 1-2 days typical |
| Work + Travel | 250-500W mixed | Fridge, laptop, monitor, lights | 2 kWh station class | 2-4 days typical |
| Comfort Setup | 500W+ or high peaks | Cooking, longer trips, solar support | 2-5 kWh station + solar | Assisted sizing |
Technical notes before buying
- Ask for days off-grid, solar yes/no and whether cooking/heating is included. That decides the tier quickly.
- Vehicle charging helps between stops but should not be the only recharge plan for long stays.
