Does it receive NOAA weather channels?

It is marketed as an emergency weather radio, but the listed bands are AM, FM and shortwave. NOAA weather channels sit in the VHF band, so check that your local weather frequency falls within the tuning range before relying on it for alerts.

Does it alert you automatically when a warning is issued?

No. It has no SAME decoder or automatic alert tone described, so you have to be listening to hear a warning. For hands-off alerts, a dedicated weather-alert radio is the better fit.

Can I listen without disturbing others?

Yes. It has a headphone jack, so you can plug in earbuds for private listening, which is useful in a shelter or at night.

Does it need batteries or wall power?

The listing does not specify a power source. Plan on standard batteries for portability and check the label for a DC input if you want to run it from an outlet.

Is it good for shortwave listening?

It tunes shortwave alongside AM and FM, which is uncommon at this level. Expect basic sensitivity, so a long wire antenna or careful positioning helps on distant stations.
