Dual-port car charger for phones and tablets

The TeKit 20392 plugs into a 12 to 24 volt socket and provides two USB ports with a combined output of 3.4 amps. One port delivers up to 2.4 amps for tablets while the second supplies 1 amp for smartphones. A built-in smart IC detects each connected device and adjusts the current automatically.

Thermals, noise and power draw in normal use

The charger operates from the vehicle's DC supply without a fan, so it runs silently and adds negligible load to the electrical system. Intelligent circuit protection guards against short circuits, over-heating, over-current and over-charging during extended sessions. An integrated LED indicator shows power status without distracting the driver.

What this replaces and when the jump is worth it

It replaces single-port chargers that force users to choose between a phone and a tablet on the road. The upgrade makes sense for drivers who regularly need both devices powered at once, especially on longer journeys. Buyers who only ever charge one device at a time will not benefit from the second port.

Questions about this item

How do I install the TeKit 20392 and what step do people often miss?

Plug it into the 12-24V cigarette lighter socket until it clicks; the step people miss is checking that the LED indicator lights up to confirm power is flowing.

What maintenance or replacement will the TeKit 20392 need later?

No scheduled maintenance is required; if the USB ports loosen or the charger stops delivering 3.4A total, replace the unit.

What limit appears first when the TeKit 20392 runs under sustained load?

The 17W total power ceiling is reached first; the 2.4A port and 1A port share this budget so both devices charge slower once combined draw hits 3.4A.
