NOCO X-Connect Extension Cable 10-Foot — Durable Watertight Charger Extension for Genius & G-Series

The NOCO GC004 X-Connect 10-Foot Extension Cable adds ten feet of rugged, watertight extension to compatible NOCO Genius and G-series battery chargers, letting you reach batteries and accessories that are farther away.

The GC004 is a purpose-built extension lead designed to expand the working distance between your NOCO charger and the battery or accessory you’re servicing. Built with a durable, weather-resistant connector and heavy-gauge cable, it preserves reliable power transfer and makes positioning your charger easier in garages, workshops, boats, and outdoor settings. It is compatible with a wide range of NOCO Genius and G-series chargers but is not intended for use with NOCO Boost or Boost X UltraSafe lithium jump starters.

How does this extension cable improve charging setup flexibility?

Adding ten feet of cable gives you more room to position the charger where it’s safe and convenient, without stretching or relocating the vehicle or battery. This is especially helpful for batteries in tight engine bays, on trailers, or in boats where charger placement options are limited.

• 10-feet of extra length for easier charger placement
• Enables charger storage away from moisture or traffic areas
• Maintains stable connection thanks to secure X-Connect locking

Which NOCO chargers and accessories work with the GC004?

The GC004 was engineered for select NOCO Genius and G-series models. It pairs directly with many chargers and accessory ports, extending their reach while retaining the original connection type and safety features.

• Compatible with G750, G1100, G3500, G7200, and G4 models
• Works with GENIUS1, GENIUS2, GENIUS2X2, GENIUS2X4, GENIUS5, and GENIUS10
• Not compatible with NOCO Boost or Boost X UltraSafe lithium jump starters

Is the cable durable enough for outdoor and workshop use?

Yes — the GC004 uses a rugged, weather-resistant connector and heavy-duty cable jacket to handle typical shop, garage, and marine conditions. The connection is designed to resist moisture ingress and mechanical wear that can interrupt charging or accessory operation.

• Watertight connector for protection against splashes and damp environments
• Durable outer jacket resists abrasion and flexing
• Secure locking design prevents accidental disconnection

Can I use this cable for jump-starting or other NOCO products?

The GC004 is intended to extend charger connections and compatible accessory leads, not to interface with NOCO Boost or Boost X lithium jump starters. Use it only with supported Genius and G-series chargers to ensure correct operation and safety.

• Extend charger-to-battery connections for supported models only
• Do not connect to NOCO Boost or Boost X UltraSafe jump starters
• Check your charger model compatibility before purchase

Who this is for: The NOCO GC004 X-Connect 10-Foot Extension Cable is ideal for vehicle owners, boaters, mechanics, and hobbyists who need added reach from a compatible NOCO Genius or G-series charger. If your charger’s placement is limited by space, moisture risk, or access issues, this extension provides a straightforward, durable way to relocate the charger without compromising the connection. Avoid purchasing if you plan to use it with NOCO Boost series jump starters.
