Aye Up,
At last, I've been waiting for someone to invent the under water light to extend my covert basher up locations!
Seriously though - a potentially useful piece of kit - arguably in a very select situation though. (Wind turbine better Jared? In Wales I bet it would work in the rain!!! lol).
Or Manchester.
Most of the locations that I frequent or at least lay up at don't have a running water course or only one with a weak flow (no info on water current-to-charge-generated detail in video).
The charging time (4.5hrs) and the size of the unit would have to come down considerably for me to consider carrying it over the equivalent number of
pre-charged power banks that I could carry - possibly x 6.
As Trotski states - 3rd party review required.
Having had a look at the site it looks like a kickstarter project and the minimum price for one (if I have read correctly?) is $180.
'ow much!!!!!!
