Camping power supply: The best cables for motorhomes and outdoor adventures

Camping holidays mean freedom, nature and adventure - but a reliable power supply is also essential, whether in a motorhome, in a tent camp or when glamping. Choosing the right cables not only ensures convenience, but also safety. In this article, we show you which cables are particularly suitable for outdoor use and what you should look out for when buying them.
1. basics of the camping power supply: What you need to know
Power connections on campsites usually supply 230 V alternating current with 4-16 A fuse protection. This corresponds to 920 W to 3,680 W - a decisive factor when choosing appliances. Important: Not all campsites offer the same power. You should therefore find out in advance about the maximum current output (amperes) and adjust your appliances accordingly.
Terms explained simply:
- Volt (V): Voltage - usually 230 V in Europe
- Amperes (A): Amperage - decisive for the load capacity
- Watt (W): Power (W = V × A)
2. CEE extension cable: Robust, safe & standard-compliant
CEE plugs are standard for many motorhomes and campsites. These standardised blue plugs (230 V, 16 A) are splash-proof (IP44) and mechanically stable.
Our recommendation: CEE extension cable with H07RN-F rubber cable - oil-resistant, UV-stable and ideal for outdoor use. Important: The cable reel should be fully unwound to prevent overheating.
✔ Ideal for:
- Connection from the campsite power box to the motorhome
- Humid or demanding environments (e.g. forest, beach)
- Durability due to resistant material
3. H07RN-F rubber cable: The flexible solution for travelling
This cable is a real all-rounder: high mechanical strength, resistant to oil and cold, as well as UV-resistant. Ideal for temporary power installations, mobile distributors and outdoor areas.
At ekabel24.de you will find H07RN-F rubber cables in various cross-sections (e.g. 3×2.5 mm²) and lengths - by the metre or ready-made.
4. solar cables & self-sufficient power supply for independent campers
Solar cables are the perfect solution for anyone travelling independently of mains power. The H1Z2Z2-K cable type has been specially developed for photovoltaic systems - halogen-free, UV and ozone resistant and temperature resistant from -40 °C to +90 °C.
This allows solar panels to be safely connected to charge controllers and on-board batteries - ideal for self-sufficient motorhomes, vans or tiny houses.
✔ Advantages:
- Flexible for mobile solar systems
- Durable even in direct sunlight
- Resistant to water, wind and mechanical stress
5. safety tips: How to keep camping electricity safe
Outdoor electricity harbours risks - so caution is advised. Our recommendations for maximum safety:
- Make sure the protection class is at least IP44 (splash-proof)
- Only use tested cables with CE certification
- Unwind cable drums completely - otherwise there is a risk of overheating
- Check cables regularly for cracks, breaks or corrosion
- Do not use cheap household extensions - only use outdoor-certified material
6. accessories, adapters & distributors: Practical and necessary
An adapter from CEE to Schuko (household plug) is often required - ideal for electrical appliances with a standard Euro plug. Mobile distribution boxes with RCDs also increase safety - especially in damp environments.
For larger setups (e.g. with a cool box, coffee machine and light), multiple distribution boxes with surge protection are recommended.
7 Our recommendation: You should have these cables with you
- CEE extension cable 25 m with IP44 & rubber sheathing
- H07RN-F rubber cable - individually shortenable & robust
- H1Z2Z2-K solar cable for self-sufficient energy
- CEE adapter to Schuko
- RCD circuit breaker for additional safety
🔎 Extra tip:
Calculate your power load before travelling. Add up the wattages of all appliances (e.g. kettle 2,000 W, fridge 100 W, laptop 50 W) and compare them with the campsite's power supply.
Conclusion: Safety, quality & flexibility - with cables from ekabel24
Whether on the campsite, in the forest or on the festival site - with the right cables you are always well supplied. Our recommendation: rely on tested products such as H07RN-F rubber cables, CEE extensions and solar cables for maximum safety and convenience.
