Any who recreates near or in moving water — kayakers, fly fishers, sailors, and even backpackers — will be interested in the new Estream portable power generator. Just throw it in the water while you play or sleep next to the river, and in the morning you enough stored up power to recharge your phone 3 times over.
Created by South Korean firm Enomad, the Estream is a portable water-power generator that converts any type of moving water, such as that from a river or when being pulled behind a boat, into stored energy to charge almost any of your USB-powered devices when you are off the grid.
So how does it work?As a generator, it produces 2.5W – 5W of energy. When the Estream is suspended in water, the water flow rotates the turbine. This mechanical rotation is converted into AC power by the generator through electromagnetism. The AC power is then converted into DC to be stored in the battery.
It takes about 4.5 hours to fully charge the 6,400 mAh built-in battery using running water. Once fully charged, the battery can charge up to 3 smartphones, GoPros or even tablet PCs twice as fast as a regular outlet. It is rechargeable, so as long as you you have access to running water you can continue to charge your devices — even on the longest adventures.
The Estream weighs 1.8 pounds and folds up into a thin, 10-inch package — small and light enough to take with you wherever your adventures might lead. It also has patented modular design that enables it to be used as a lantern, speaker, Wi-Fi router, and much more.
For a $180 pledge over on Kickstarter, you can pre-order your Estream portable water power generator.
