Some transmitters may require additional power sources or may not last as long as others. Always check the specifications and user reviews to ensure you’re getting a reliable and long-lasting product.

Regulatory Compliance

Before using an FM transmitter, make sure it complies with local regulations. In some countries, it might be illegal to use an FM transmitter without a license.

Whether you choose a pre-made adapter or a DIY option, the key is to do your research, understand the features and limitations, and find a product that meets your needs.
