CTEK Battery Charger Magnetic Adapter Plug

with Charge Indicator

The MAGRING is a revolutionary magnetic connector system for 12V charging.


Newly updated for 2021! Features stronger magnets stronger internal contacts & higher quality outer housing for a longer life


Magnets in the housing of the plugs contact two parts of the connector allowing for an easy charging routine. Magnets in the clip (cable) and socket (on vehicle) ensure contact is made between the two parts of the connector as well as providing a switching function. The flat contacts only carry power when the moveable plate in the Port is magnetized by the magnets in the Clip. Totally short-circuit-proof the clip is designed to avoid other metal objects or permanent magnets inadvertently energizing the contact.

This connector has been professionally assembled in house by our cable experts with a CTEK traffic light plug which allows fitments to all magnetic boot charging ports with all current and old CTEK chargers.

This allows the user to use any existing CTEK charger (up to 15Amps) with their vehicle; rather than buy a new branded charger.

The traffic light plug shows one of 3 coloured lights for a instant visual charging progress; red for low voltage amber for charging and green for fully charged.

Total length is approximately 35cm.


This plug is not to be used on vehicles with lithium batteries installed – please see our inverted version specifically for lithium batteries
