USB-C Audio and Charging Adapter

The LERTOSEN LTS-K02 is a compact 2-in-1 dongle that adds a 3.5 mm headphone jack and a USB-C power input to phones, tablets or laptops that lack a built-in audio port. It targets users who want to keep using wired headphones while the device charges.

Metallic Connectors and 13 cm Cable

Both the USB-C plug and the 3.5 mm socket feature metallic plating for durability and a secure fit. The short 13 cm tether keeps the adapter close to the device, reducing strain on the port during daily carry or desk use.

Check Port Protocol and Headset Wiring

Verify that your host device supports audio output and Power Delivery 3.0 up to 60 W over its USB-C port; the adapter does not work with Quick Charge 3.0. Also note that the 3.5 mm jack follows CTIA and OMTP standards but will not pass the microphone signal from Apple EarPods.

Questions about this item

What USB-C standard does the LTS-K02 use, and what charging power does it cap at?

It uses USB-C with PD 3.0 and caps charging at 60 W (20 V / 3 A) when paired with a compatible PD charger and cable.

What physical clearance does the 13 cm cable and dual-port design need to fit?

The 13 cm grey cable needs enough slack to reach both the phone’s USB-C port and a PD charger while the 3.5 mm jack sits clear of the handset edge.

How is the LTS-K02 installed, and what step do users often miss?

Plug the USB-C end into the phone, connect headphones to the 3.5 mm jack, then attach a PD charger to the USB-C port — skipping the PD charger leaves charging inactive.
