Ingenious

fr the quick charge on the USB port is no joke, my phone juices up so fast on my commute. I was lowkey skeptical but the Bluetooth audio streaming through the FM radio sounds def better than I thought it would, obv worth it.

Superb

The 20W USB-C charging is genuinely fast and I can stream audio at the same time without any issues. The built-in microphone with echo cancellation makes hands-free calls sound really clear on my end too.

Remarkable

The microSD card playback is honestly such a nice feature, I loaded up a card with music and it just works perfectly. 🤩 Having both USB-C and USB charging ports means I can keep two devices powered up during the drive without any hassle.
