If over-the-air radio stations are underwhelming, just use the line-in feature on this cordless mini radio to hook up your portable audio device or smartphone for listening enjoyment. Any RIDGID 18 volt battery (sold separately) will power this instrument for use at job sites or outdoor events, so tote it around using the built-in handle. Like any RIDGID machine, it's durably built and made to withstand bumps and knocks.
