What to know before buying

Listing details to confirm

The listing's audio details conflict: it claims 30W stereo sound, while separate fields report Stereo and 1.0 audio channel. Confirm the intended audio configuration. The claimed 18-hour battery life, IPX7 protection, floatability, power-bank function and PartyCast speaker count are listing claims, not independently verified here. The title mentions USB-C, but the supplied technical details do not confirm that port.
