2-in-1 Bluetooth 5.4 adapter

The Olipiter CP342-LTUS adds Bluetooth 5.4 to any device with a 3.5 mm aux port. It works as a receiver to upgrade car stereos or home speakers, and as a transmitter to send audio from a TV or PC to wireless headphones. It suits drivers, travellers and home users who want cable-free listening without replacing existing equipment.

Sustained wireless performance

Bluetooth 5.4 provides a stable link with low latency during extended playback sessions. The adapter automatically reconnects to the last paired device on power-up, so long drives or movie marathons stay connected without manual re-pairing. Dual-link support lets two headphones or speakers share the same source simultaneously for the full battery duration.

Battery life and charging

The built-in battery delivers 11.5 hours in receiver mode and 10 hours in transmitter mode on a single charge. A USB Type-C port recharges the unit in 1.5 hours and allows charge-while-using so the audio never stops. The compact 2.5 by 1.2 by 0.5 inch body stays cool and silent because it has no moving parts.

Questions about this item

Does the Bluetooth 5.4 adapter get warm or drain the car battery during all-day use?

The adapter runs on its internal battery for up to 11.5 hours in receiver mode or 10 hours in transmitter mode and can be charged via USB Type-C while operating, so it does not draw power from the vehicle.

What cables or ports must my car already have for this adapter to work?

Your vehicle needs a 3.5 mm auxiliary input; the adapter plugs directly into that jack and uses a USB Type-C cable for charging.

Will this Bluetooth 5.4 unit pair with an older stereo that only supports earlier Bluetooth versions?

The adapter connects through the 3.5 mm aux port, so the car stereo does not need any Bluetooth capability of its own.
