Does it really charge a phone?

Yes, through the USB port using the internal 2,000 mAh battery. Expect roughly one partial phone charge, not a full day of use, and keep the radio's own battery topped up first.

How long does the hand crank take to charge it?

Cranking is a backup, not a main source. A few minutes of steady cranking gives a short burst of radio or light, so charge by USB or sun when you can.

Does it get NOAA alerts automatically?

It receives the 7 NOAA weather bands, so you tune to your local station to hear alerts. It does not switch itself on or sound an alarm when an alert is issued.

It is water-resistant, not waterproof. Rain and splashes are fine; do not submerge it or leave it out in a downpour.

The radio itself. The Mini USB charging cable is not included, so bring your own, and note the USB port is for charging a phone, not for charging the radio.

How does it compare with bigger emergency radios?

It is smaller and lighter than most, with a modest battery and a dim flashlight. Larger rivals add a reading light, a bigger battery or a digital display, but weigh more and take more space.
