Tuner - digital tuner for fine tuning the frequency. Antenna - Small, compact, helps a bit with reception. I was able to receive local AM/FM radio stations and weather radio. Buttons - everything is properly labeled, visible and legible. The flashlight is LED and bright enough to be useful. Dynamo - hand crank works quite simply. Turned on and listened to Christmas music Speaker - One speaker. Sounds good at low volume 3 to moderate volume 7, but undesirable at higher levels. Fear - Attracts attention. Charging - Charged my phone as stated on the phone mounted on a lithium ion battery or dynamo crank. Size - Small, compact, fits easily in a glove box. It fits in my t-shirt pocket which only sticks out 1.5 inches. Weight - very light, only 9.4 ounces. If you charge the sun with diesel fuel, you'll likely spoil it by melting the body. You won't get over it for $20.
