About two years ago, Seoul-based company Enomad made news when it put mobile phone charging stations along the manmade Cheonggyecheon River that runs through the Korean capital's downtown. The stations used the force of the river to turn turbines and generate electricity. This year at Austin's SXSW festival, the company has demonstrated that it's been able to shrink the concept down to fit easily in anyone's hand – or backpack.

Also called Enomad, the bullet-shaped device is about the size of a thermos. Remove the white translucent cover and you reveal three propellers that flip down and lock into position. Once the device is assembled, you can simply place it into any flowing water source to charge it up. Alternatively, it can be towed behind a kayak or any other water vessel. The idea is to get the propellers spinning to turn an internal turbine that charges up the onboard 5,200 mAh battery.

Company representatives told Gizmag that the battery takes about two hours to charge in a normally flowing stream. Once charged, you can disassemble the rotor section from the base, where USB charging ports are revealed. The, 5,200 mAh battery should be able to charge an iPhone 6 roughly twice. If you don't want to use the Enomad to charge a device, you can also screw the translucent cover back on and push a button to have it function as a lantern.

Enomad says it was originally inspired to turn to water to generate power as a way to assist underpriviledged communities where power is scarce.

The Enomad will be launched via Kickstarter in early July. The expected retail price is US$180, so if you're an avid camper – or if you've always wanted to boast that you have a hydroelectric plant in your backpack – stay on the lookout for the campaign.

So thats about 2A charging - actually useful!

I think that could be great for campers, hikers and those living off grid.

With larger blades & a stand, couldn't it also run in wind power mode?

Very similar to this one: https://www.kickstarter.com/projects/hydropower/blue-freedom-the-worlds-smallest-hydropower-plant Got mine a few days ago. Truely awesome!

It should use a Tesla Turbine, rather than this outdated design.
