This retractable car charger with a built-in Bluetooth 5.3 FM transmitter combines multiple useful features into one device, making it a strong choice for drivers needing both fast charging and hands-free audio. It delivers a powerful 96W output through USB-C, USB-A, and Lightning ports, allowing you to charge up to four devices at once, which is great for long drives or multiple passengers.

Bluetooth 5.3 ensures a quick connection with lower sound delay and a stable link for smooth music streaming and hands-free calls. Noise cancellation and echo reduction improve call clarity, and voice navigation through your phone’s app adds to safer driving. Compatibility covers all recent iPhone models plus USB-C and USB-A devices, so it works well regardless of what phone or gadget you use.

A limitation is that it requires a 12V cigarette lighter socket, so it won’t work if your car only has USB ports. Also, while the FM transmitter lets you play music through your car stereo, audio quality can vary depending on your car’s FM reception. For someone looking for a clutter-free charging station combined with reliable Bluetooth calling and music streaming, this device presents a practical and efficient option.

This makes it a versatile choice for users with multiple devices. The device’s compact design might be a double-edged sword. While it's easy to fit in any car, users with larger hands might find it a bit fiddly to operate. The product’s ABS+PC material is durable, but may not feel as premium as metal alternatives. Additionally, those who prefer a non-retractable cable might not favor the automatic retract feature, as it could feel restrictive to some. The Paiholy FM transmitter is well-suited for individuals seeking a multi-functional, easy-to-use car accessory that combines charging and audio transmission, though it may not appeal to those who prioritize premium material feel or fixed cable design.

The wide compatibility with various Bluetooth devices and support for voice assistants like Siri and Google Assistant make it a convenient and user-friendly option. However, the product does have some potential downsides. The display screen is basic and might be difficult to read in bright light conditions.
