FLAT-OUT 20m 15amp Ext Lead Ex-H-Duty (2.5mm² Core) on Multi-Reel - ORANGE. M2015HS

When you're running power across a longer campsite, what's inside your extension lead matters. The Flat Out 20m 15A Heavy Duty Extension Lead uses a larger 2.5mm² copper core to help minimise voltage drop over distance, giving high-draw appliances the power they need when you need them most.

For caravanners, that can matter on a hot afternoon when the air conditioner compressor kicks in. Start-up can demand considerably more current than normal operation, and excessive voltage drop through a longer, thinner lead can make it harder for appliances to start and operate as intended. The heavier 2.5mm² conductor helps reduce that voltage drop, providing a more robust connection for demanding caravan and RV setups.

It's also built to make campsite power easier to manage. The heavy-duty silicone rubber cable remains flexible, resists kinking and lays flatter when unrolled, while the included Flat Out Original Multi-Reel keeps all 20 metres neatly wound and ready for the next stop.

Why Choose a 2.5mm² Core?

The AS/NZS 3001.2:2022 standard recommends a 2.5mm² conductor for caravan supply leads longer than 15 metres.

More copper means lower electrical resistance, helping reduce voltage drop across the 20m cable. This makes the lead particularly well suited to caravans and RVs running higher-draw appliances such as air conditioners, induction cooktops, microwaves and coffee machines.

Key Features

• 20m reach: Extra length for sites where the power outlet isn't conveniently located beside your caravan

• Heavy-duty 3 x 2.5mm² core: Larger conductor helps minimise voltage drop over longer distances

• Suited to high-draw appliances: A robust power connection for caravans using appliances such as air conditioners, induction cooktops and microwaves

• Flexible silicone rubber cable: Designed to lay flat with minimal kink or coil memory and rewind smoothly after use

• UV stable: Carbon-infused black cable provides long-term protection against UV exposure

• Outdoor-ready cable: Waterproof cable jacket is designed for outdoor conditions; plug and socket connections must still be protected from water ingress during use

• Cold-weather friendly: Silicone rubber remains flexible and easier to handle in colder conditions

• Clear 15A plug and socket: Makes visual inspection easier before use

• LED power indicator: Quickly check whether power is present at the socket

• Original Multi-Reel included: Keeps the heavier 20m cable organised and easy to deploy and pack away

When Should You Choose This Lead?

If you're travelling with a caravan or RV and want a longer 20m supply lead, particularly when running demanding appliances, the larger 2.5mm² core gives you additional electrical headroom where a smaller conductor may experience greater voltage drop.

It's a small detail hidden inside the cable, but when you're parked further from the power outlet and relying on your appliances to perform, it's one worth having.
