We compared two Bluetooth FM transmitters for the car: the LENCENT FM Transmitter and the Syncwire Bluetooth 5.4 FM Transmitter.

What we looked at

Bluetooth version, USB charging, extra features, and price.

The verdict

If you want a long-established model with a car battery voltage display and the largest review history, the LENCENT is the pick at £13.99. If you would rather save £1.58 and get Bluetooth 5.4 with PD 36W fast charging, the Syncwire is the alternative, at £12.41.
