CTEK Connect CIG Plug permanent 12V socket — fits 12 & 21 mm, for CONNECT chargers

CTEK Connect CIG Plug lets you permanently wire a vehicle cigarette/accessory socket to a CTEK charger so you can charge batteries without accessing awkward battery terminals.

The CTEK Connect CIG Plug provides a tidy, durable way to charge vehicle batteries through the 12V accessory outlet. Designed to pair with a wide range of CTEK chargers, it removes the need to crawl into tight spaces or repeatedly open panels just to attach clamps. Built and tested in Sweden, the accessory fits both standard 12 mm and larger 21 mm sockets and includes a strain-relief design for safety and longevity.

How does the CIG Plug make charging easier?

Instead of dismantling trim or reaching into cramped engine bays, you can plug your CTEK charger into the permanently installed socket inside the vehicle. This saves time and reduces wear on battery terminals and connector clamps.

• Permits charging from inside the car through the 12V accessory outlet.
• Works with many CTEK models featuring Comfort Connect or CONNECT system.
• Fits both 12 mm and 21 mm accessory sockets for broad compatibility.

Is it safe and built to last?

The CIG Plug is engineered for repeated use: flexible, hardwearing cables and a maze-like strain relief protect the connection from pulling and moisture. Because it’s tested in Sweden, the design emphasizes durability under everyday automotive conditions.

• Maze-like strain relief reduces cable stress and entry-point wear.
• Flexible heavy-duty cable resists cracking and hardening over time.
• Backed by a 2-year warranty for added peace of mind.

Which CTEK chargers and vehicles is it compatible with?

The plug is compatible with many CTEK models that use the CONNECT interface, including Comfort Connect-equipped chargers and a range of MXS and MULTI series units. Note that the vehicle’s accessory socket must remain powered with the ignition off to charge through the outlet.

• Compatible with Comfort Connect, UC 800, US 800, MULTI US 3300 and similar models.
• Works with MXS 5.0, CT5 Time To Go, MULTI US 7002 and other CONNECT-equipped chargers.
• Requires the vehicle accessory socket to be live when ignition is off.

How simple is installation and everyday use?

Installation is straightforward: the plug is designed to be mounted as a permanent connection to the vehicle socket and then used like a normal cigarette outlet. Once installed you simply attach your CTEK charger’s CONNECT lead for fast, tool-free charging.

• Quick attach/detach with CTEK’s CONNECT system—no tools needed for daily use.
• Permanent wiring keeps the battery accessible without repeated terminal handling.
• Fits common socket sizes for flexible mounting locations.

Who is this for: The CTEK Connect CIG Plug is ideal for vehicle owners who need regular, convenient battery charging without accessing the battery directly—motorcycle riders, classic car stewards, fleet operators, and anyone with hard-to-reach battery locations. It’s also a practical option for technicians and enthusiasts who use CTEK chargers frequently and prefer a tidy, reliable outlet for routine charging.
