Emergency Radio SANGEAN MMR-884K maps includedcarefully handcrafted topology and maps.

Reinforced in shock-resistant rubber on all 4 corners, the MMR-88 is built like a tank. Equipped with a solar panel as well as a dynamo hand crank generator, the radio can power itself up without relying on a wall charger. There's also a triple LED light with brightness and SOS settings.A 38mm speaker unit to offer you balanced sound with the right amount of bass and treble. Hook up the pair of 3.5mm headphones and enjoy the radio.

Great Reception and SoundMMR-88 outperforms many of the emergency radios I have seen, especially on FM & NOAA Weather Bands where reception is exemplary with pleasant audio.Unlimited PowerWith the combination of solar panel and a hand crank generator, your MMR-88 will last as long as you need it to.An emergency radio is, broadly speaking, a radio receiver designed to remain functional in cases of power outage or isolation from contact with civilization. Such radios are often designed to run on minimal or renewable power sources, such as solar.

Emergency radios are generally designed to cover the standard AM and FM broadcasting bands, and weather radio in countries that provide that service. Basic shortwave radio coverage (for situations where local radio is out or not available) is less-common.

Common to all emergency radios is the need to maintain power as long as possible in times of power failure. Commonly, such radios are designed to use minimal battery power, and a common feature (especially on units sold in less-developed countries where electrical supplies may be unreliable or nonexistent) is a hand-cranked electrical generator along with a rechargeable battery to store the generated energy (the device is sometimes known as a clockwork radio). A few, such as the Blackout Buddy from Eton Corporation, and the Adventurer from Ambient Weather are designed to recharge from wall current. Some emergency radios can also be powered by an attached solar panel.

One element that separates some emergency radios from other types of radios, is the ability to broadcast alerts via the Emergency Alert System, even when the radio sound is turned off. This is especially useful in areas where sudden storms, tornadoes, tsunamis or other fast-breaking emergencies can occur. Some emergency radios are designed to also charge other devices, such as cell phones or mp3 players, but this can vary widely.
