What is a Portable Generator (and Who Needs One)?
A portable generator is exactly what it sounds like, a compact, often wheeled unit that provides on-demand power anywhere. They’re ideal for:
-
Camping / caravanning / campervans
-
DIY / job sites without mains power
-
Outdoor events and stalls
-
Backup power during outages
- Horseboxes, cars, vans
Unlike heavy standby units, these are designed for easy transport and quick use, often with pull start or electric start, and running on petrol.

Portable Generator Buying Tips
Power Output
Make sure the wattage matches your needs. For laptops and lights, 1–2kW is fine. For tools or appliances, aim for 3kW+.
Noise Levels
Inverter models are much quieter (as low as 58dB), while open-frame models can reach 70–100dB. For campsites or quiet areas, go quiet.
Inverter vs Conventional
If you’re running sensitive electronics, always choose an inverter generator. If you’re running tools or floodlights, a standard petrol unit is fine.
Portability
Most models under 40kg are easily portable, especially with wheels or carry handles. For true grab-and-go use, look for anything under 25kg.
