Wind Crank

What kind of LED flashlight is better? Trembling, Crank, Wind-Up, or traditional batteries?

I just tried to light my lantern traditional and not work. I know it must be that the battery died. It is the great and the batteries are expensive. So I'm looking to get a new flashlight, one of an LED. My friend Wind-up is the one in which you can take a crowbar and turn just for a minute and run for 30 minutes. My other friend has Crank those where there is a piece budge on the side and just press a couple of times. Then when I saw on Google, are shaking. I wonder from your experience that they work better and more efficient. I looked at eBay and are not all about $ 6 each, and well, if I have to buy new batteries at a comparable price, you can also get a new one. Thanks in advance for your help!

I never had good luck with the guy who shake. They work for a bit and then stops. I prefer the wind-up type. They are much more reliable. I mainly use the type of battery, wind-up but others are large. You just store them and they are there when needed. Do not worry about the batteries running out or leaks.
