15 minutes per minute of cranking? That’s pretty good.


#3

I’m guessing that’s more a function of the LED light — it doesn’t say how much light is given out during those 15 minutes.

Any info on how much power is stored per each minute of cranking? E.g., how much would you have to crank it to be able to charge your phone enough to make one call?

Just don’t make Crank angry.


#5

They should make a margarita version… Hand cranked blender that also charges your phone (could still have a LED flashlight at the end)


#6

$15? Certainly looks flimsy.

YOU MANIACS! YOU BLEW IT UP! AH, DAMN YOU! GOD DAMN YOU ALL TO HELL!

If you remember the One Laptop Per Child prototypes, they started with a crank on the laptop. This was an ergonomic nightmare, cranking is terrible for anything beyond a few minutes of low power LED light, grinding pepper onto your salad, or maybe ringing an old style phone.
They went to a Nordictrack style yo-yo pull generator before abandoning kinetic power for solar and mains. Kinetic power only begins to make sense when you stick it inside a bicycle hub for anything above a low hundreds mA per hour.
(edit)OK, fine, margarita blender too I guess…
