Last year, a hydropower portable device called Blue Freedom triggered widespread attention once it landed on the kickstarter crowdfunding platform. The advantages of environmental protection, portability, and ease of use made it finally successful in crowdfunding, with 958 users and 190,353 euros in support. However, the development team did not fulfill its delivery commitment last October. Follow-up news was rarely reported by the media. Today, we discovered a new product in the kickstarter that uses hydroelectric power generation, Estream, which is dedicated to becoming a user's own micro power station, allowing users to fear from the city's power network.
Consistent with Blue Freedom's principle of power generation, Estream relies on the flow of water to drive the turbine. The built-in generator (2.5W to 5W) converts mechanical energy into electrical energy. The resulting electrical energy is then stored in a 6500mAh battery. It takes 4.5 hours to fill. Once charging is complete, the Estream can connect up to three smartphones, GoPros or even tablet PCs via a USB interface (compatible with most devices), charging twice as fast as regular sockets. What needs to be reminded is that even if the water flow is gentle, Estream still can generate electricity, but the charging time will be extended to a certain extent.
Compared to the Blue Freedom, it weighs only 57g. Although the Estream (800g) is not a very lightweight product, its cylindrical shape makes it suitable for carrying on any backpack. In addition, Estream also adopts a patented modular design, where the generator part and the battery part are detachable, and the battery supports the use of extended equipment such as lampshades, speakers, and WiFi routers.
The product debuted at this year's SXSW (southwest southwest music festival) conference, where numerous testers expressed their love for it, saying "this is a remarkable innovation" and "one of the coolest products."
The development team stated that Estream's target users are not only backpackers who love wild adventure and travel, they also hope to use this product to arouse people's attention to energy issues, advocate people to use 100% renewable green energy, and reduce dependence on grid power generation. .
If you are interested in Estream, you can now purchase the product crowdfunding page for $180 (super early bird price) to purchase. The kit includes the Estream body, turbine housing, product cover, USB cable, cable, and operating instructions. If all goes well, the product will be delivered in March 2017.
