Interesting product someone showed me online. I searched and haven't seen it mentioned on Sigforum. Has anyone used this?

Dang, I hadn't even looked at the price yet...I'm curious if it works in the real world.

It's actually a clever concept but for backpacking/hiking you're better off just carrying a battery pack...it'd be cheaper & weigh less.

If you're going to be in an area that has a fast-moving stream for a few days but doesn't get very good sun exposure, it'd be ideal.

for $24 you can add the optional hand crank when you are running out of power, at night, no wind, no water, in the desert....

If you want to crank it sometimes maybe this...

I can make the same thing with a fan, some magnets, and a rectifier. The hardest part would be voltage regulation as the voltage would change depending on wind/water speed. AVR wouldn't work because the use of permanent magnets VS electromagnets.

As far as the product itself, pointless. I'll just pick up a half dozen 20,000 mAh battery packs and weigh less or 3 or 4 batteries and solar charger.

Amusing review
