What this adapter does

The Scosche S2 plugs into a 12‑24 V vehicle socket and adds Bluetooth 5.3 audio streaming, hands‑free calling and dual‑port fast charging to any factory or aftermarket stereo. It targets drivers who want wireless music and clear calls without replacing the head unit.

What the bundle changes

A built‑in microphone with CVC 8.0 noise suppression cuts road and engine sound during calls. Two USB ports deliver 30 W via Type‑C and 12 W via USB‑A, charging a phone to 80 % in roughly 30 minutes while powering a second device. A 3.5 mm auxiliary input and USB‑drive playback give three ways to hear audio.

Install notes and common issues

Insert the transmitter, tune the car radio to an unused FM frequency and pair the phone; the unit auto‑reconnects on next start‑up within a 33 ft range. Vehicles with dense FM spectra may need manual frequency hunting. The adapter does not suit cars lacking a 12‑24 V accessory socket or drivers who require a direct wired audio connection.

Questions about this item

Does the built-in microphone need any cleaning or replacement over time?

The microphone is built into the adapter and has no user-replaceable parts; no scheduled maintenance is required.

What charging limit appears first when both ports run at full 30W and 12W output?

Total power is capped at 42W, so the combined draw cannot exceed that figure.

How hot or noisy does the unit get during an all-day drive?

It includes over-heating protection and has no fan, so it runs silently and stays within safe temperature limits.
