Essential Camping Accessory: Flexopower Extension Cables

As the warmer season rolls in and South Africans start gearing up for summer adventures, overlanding trips, and December holidays, many campers are upgrading their solar power systems. Solar panels, portable batteries, and camping fridges usually top the shopping list.

But there’s one small accessory that often gets overlooked — and yet it can make or break your entire camp setup: solar extension cables.

The Shade vs. Sun Challenge

Every camper knows the dilemma:

• You want to park your vehicle or set up camp in the shade to stay cool.

• But your solar panel needs to sit in the sun to deliver maximum charging power.

Without an extension cable, you’re forced to compromise: either your fridge and batteries sit in the sun (overheating and draining power), or your panels sit in partial shade (losing efficiency).

With the right extension cable, you no longer have to choose.

Why Extension Cables Are Essential for Camping Solar

Flexopower extension cables give you the freedom to:

• Keep your vehicle, fridge, and batteries cool in the shade.

• Place your solar panel in full sun, exactly where it performs best.

• Lay out your camp the way you want, not the way short cables limit you.

The result? Efficient charging, longer-lasting equipment, and a more comfortable campsite.

Flexopower Extension Cable Range

Our extension cables are purpose-built for outdoor life: engineered for minimal voltage drop, fitted with original Anderson SB50 grey connectors for secure plug-and-play connections, and finished with a convenient closing strap for tidy packing.

We’ve carefully calculated the ideal lengths for different setups:

• 10m & 15m extension cables – Best suited for Namib-150W, Namib-240W, Mojave-260W and Karoo-230W.

• 20m & 25m HiVolt extension cables – Designed for high-power panels such as the Kalahari-300W and Kalahari-400W HiVolt. (Not recommended for low-voltage panels, as longer runs can cause unnecessary voltage drop.)

Quality You Can Trust

Extension cables may look simple, but quality makes all the difference when you’re off-grid. Unlike generic cables — often made with thin wires, poor-quality connectors, and high voltage drop — Flexopower extension cables are built to last.

• Engineered for efficiency: Proper 4mm² cable thickness minimizes power loss over distance.

• Fitted with Original Anderson Connectors: Widely recognized as the industry benchmark, these connectors ensure reliable, safe, and secure connections every time. At Flexopower, we don’t cut corners with imitations or knock-offs — only genuine Anderson connectors, proven in the field, make it onto our cables.

• Durability-tested: Designed for the dust, heat, and rugged conditions of African overlanding.

• Plug-and-play compatible: Works with all Flexopower panels, no adapters or splicing required.

When planning your next camping or overlanding trip, don’t just focus on the big-ticket items like panels and batteries. The humble extension cable is the accessory that gives you true freedom: park your vehicle in the shade, place your solar panels in full sun, and enjoy efficient, worry-free power wherever you go.
