Ruth's sister Car Battery Terminal Clamp Clip 12V 10A 120W 0.5 m internal power cable

SKU CH-CQN8-J6VG5

Converts a battery terminal into a 12 V socket delivering up to 10 A with a 0.5 m lead

  • 12 V output runs 12 V camping pumps
  • 10 A rating delivers up to 120 W power
  • 50 A clamps connect securely to battery terminals
  • 5 m cable reaches nearby devices easily
  • Nickel-plated iron clamps resist corrosion in use

Purpose and fit

This cable connects a 12 V car battery terminal to a standard cigarette-lighter socket using a 0.5 m lead. It suits campers, off-road drivers or anyone powering a 12 V pump, compressor or charger directly from the battery posts.

Current and length limits

The adaptor is rated for 10 A continuous output and 120 W at 12 V, while the clamps themselves accept up to 50 A. The half-metre wire length restricts placement to positions close to the battery, so devices must sit nearby.

Compatibility checks

Verify that your battery posts fit an 80 mm fish-clamp jaw and that the socket aperture of 21 mm matches your plug. The red clamp marks positive and the black clamp negative; reverse polarity will damage connected equipment. Ensure the 12 V system voltage matches the adaptor’s input and output rating.

Questions about this item

Should I pick the 0.5 m cable or a longer one?

The cable is 0.5 m long; choose this length if your battery terminals sit close to the device you are powering.

What does the 120 W rating mean when I plug in a pump?

At 12 V the circuit can deliver up to 120 W, so a 12 V pump drawing 10 A or less will run without overloading the adaptor.

Will the cigarette-lighter socket accept standard 12 V plugs?

The socket has a 21 mm aperture and 37 mm total length, matching the common 12 V accessory plug size used on most car chargers and camping pumps.
