I don't know when this is from; it came out of my house. It looks almost exactly like the "Dretec Hand-Crank Charging Radio PR-306." Actually, it's completely identical. The only difference seems to be the color of the tuning bar, which is either red or yellow. I couldn't find much information searching for "isk crew." I'm not sure if it's an OEM product or a copy, but it seems like most of these are from Dretec. Condition: There are no major noticeable scratches. The antenna is also clean. The battery box is clean as well. Both AM/FM reception works. The light also works normally (though it's not LED, of course). Power Generation: I tested how long the radio would play after cranking the handle 120 times per minute, and it played for about 14 minutes. The light, unsurprisingly, consumes a lot of power and only stayed on for about 30 seconds. I don't really trust these types of products, but I was impressed that the radio could play for about 14 minutes after a minute of cranking, so I think it's usable. The light is tough without batteries. Size (approximate): H: 67mm, W: 148mm, D: 50mm The following is a product description: [Multi-functional Design] This radio combines radio and light functions.
