CTEK Connect CIG Plug — Permanent 12V Accessory Socket Adapter, Fits 12mm & 21mm, CONNECT Compatible

The CTEK Connect CIG Plug provides a permanent, safe way to charge batteries through a vehicle’s 12V accessory socket without repeatedly accessing the battery.

If your battery is tucked away or difficult to reach, the CTEK Cig-Plug lets you connect a compatible CTEK charger quickly via the vehicle’s cigarette-style outlet. Designed for use with a wide range of CTEK chargers (Comfort Connect, UC 800, US 800, MULTI US models, MXS 5.0, CT5 Time To Go and more), this accessory is built for reliability and convenience. It fits common 12 mm and 21 mm sockets and includes a robust strain-relief to protect the cable and user while charging.

How does the CTEK Cig-Plug make charging easier?

The Cig-Plug turns the vehicle’s 12V accessory socket into a permanent charging point so you don’t have to access the battery repeatedly. It connects directly to a CTEK charger via the CONNECT system for a fast, tool-free hookup.

• Permanently installed cable for hard-to-reach battery locations
• Quick attach/detach with CTEK CONNECT compatibility
• Works while vehicle ignition is off, if the socket stays live
• Fits two common socket sizes: 12 mm and 21 mm

Is the connection safe and durable for regular use?

Yes — the Cig-Plug is designed and tested in Sweden with durable materials and a maze-pattern strain relief to reduce wear and protect the user. The cable and plug endure repeated use and resist flexing damage over time.

• Maze-like strain relief reduces cable stress and extends lifespan
• Hardwearing, flexible cable for frequent installations and removals
• Tested construction designed to withstand automotive environments
• Includes a 2-year manufacturer warranty for added confidence

Which CTEK chargers and vehicles can I use this with?

CTEK Cig-Plug is compatible with many CTEK charger models and most vehicles that provide a live 12V accessory socket when the ignition is off. Check the vehicle socket behavior first to ensure charging will occur with the ignition off.

• Compatible chargers: Comfort Connect, UC 800, US 800, MULTI US 3300, MULTI US 4.3, 4.3 Test & Charge, 4.3 Polar, MXS 5.0, CT5 Time To Go, Multi US 7002
• Vehicle requirement: socket must remain powered with ignition in the off position
• Fits both 12 mm and 21 mm accessory sockets for broad vehicle fitment

How quick is installation and everyday use?

Installation is straightforward: route the cable to the desired location and insert the plug into the vehicle socket. Everyday charging is then a matter of plugging your CTEK charger into the CONNECT end — no battery access needed.

• Simple permanent mount to keep the socket available for charging
• No battery terminal handling required for routine charging
• Save time on seasonal maintenance, storage, or long-term vehicle care

Who is this for? The CTEK Connect CIG Plug is ideal for car, motorcycle, and powersports owners with batteries that are inconvenient to reach; fleet managers, classic car collectors, and anyone who prefers a neat, permanent charging point will value the convenience. It’s also suitable for people using the specified CTEK chargers who want a safe, durable, and quick way to keep batteries maintained without repeated battery access.
