Imagine going camping deep in the woods, and then your mobile phone runs out of juice. And then your pocket charger runs out of juice, too. Sounds like you're doomed. However, with Estream you have nothing to worry about.
Enomad's Estream is a light (800g) and sustainable turbine that you can carry with you. It is capable of generating over 5 watts of electricity, which is sufficient to charge a smartphone or any other smaller smart device.
The handy (24.5cm x 6.5cm x 21cm) and very durable water-power generator doesn't require a wild river to run it, as it works perfectly fine in shallow streams with low-velocity. It converts any type of moving water into stored energy which enables you to charge every usb-connected mobile devices. A perfect solution for all the times you need your devices to work even while being off grid.
The portable waterproof (IPX 8) turbine is made of ABS and Poly Carbonate and comes equipped with a 6,400mAh built-in Lithium-Ion battery than can be fully charged in 4.5 hours. Once charged, it can charge up to 3 smartphones, GoPros or even tablet PCs, twice as fast as a regular outlet.
As long as you you have access to running water, be sure your devices will never run out of juice.
