BERTHALESS C1 4-in-1 Retractable Car Charger Grey

What the charger does and who it serves

The BERTHALESS C1 is a 4-in-1 retractable car charger that plugs into a 12 V or 24 V socket and delivers up to 2.4 A at 5 V across four ports. Two 80 cm cables with USB-C and Lightning tips extend and retract automatically, while an extra USB-A and USB-C socket sit on the body for simultaneous charging of up to four phones or tablets. It suits drivers and passengers who want a single tidy hub for mixed-device trips.

Behaviour on long journeys

Integrated over-charge, over-current and over-temperature protection keeps output steady during extended use rather than throttling after a short burst. The 12 V to 24 V input range maintains consistent power across sedans, SUVs and trucks without voltage sag. Four devices can draw power together for the duration of a road trip, and the retract mechanism cycles reliably each time a cable is pulled and released.

Thermals, noise and power draw

The unit runs silently with no moving fan, relying on passive dissipation through its housing. Protection circuits limit temperature rise during multi-device charging, so the surface stays safe to touch. Power draw follows the 2.4 A per port ceiling, and the 180° rotating head lets you position the charger away from gear-shift clearance without adding strain to the socket.
