Is the NOTABRICK speaker actually waterproof?

It is listed as waterproof and intended for shower use. Treat it as splash- and spray-resistant rather than submersible, and don't leave it sitting in standing water.

How long does the battery last?

The claimed battery life is 15 hours. Expect less at high volume, and charge it via USB before first use.

Does it have stereo sound?

It is listed as stereo, but a single cylindrical cabinet with one 4.5-inch driver gives limited separation. Don't expect a wide soundstage.

Can I connect a non-Bluetooth device?

Yes. It has an aux input, so you can plug in an older phone, MP3 player or laptop with a cable.

Is it good for outdoor parties?

It is fine for a patio or small gathering, but 15W won't fill a large yard. For bigger spaces, a larger multi-driver speaker is a better fit.

What comes in the box?

The set includes the speaker itself. Check the listing for the charging cable, since accessories vary by seller.
