Stay in touch while fishing with a water-powered generator

A new portable generator converts any type of moving water into stored energy to charge USB-connected mobile devices.

A Kickstarter campaign has provided the funding for a new portable generator — the Estream — to be developed for use by anyone in the great outdoors. Estream is a portable water-powered generator that converts any type of moving water, such as that from a river or stream, into stored energy to charge most of today’s USB-connected mobile devices, even while you are off the grid.

How the Estream generator works

The Estream can produce between 2.5W and 5W of energy. When it’s placed in flowing water, the current rotates the turbine, generating electricity. Estream works well even in a weak current or when pulled behind your kayak or canoe.

It takes about 4.5 hours to fully charge the 6400mAh built-in battery. Once fully charged, the battery can charge up to three smartphones, GoPros or even tablet PCs, twice as fast as a regular outlet. The generator is rechargeable, so as long as you have access to running water, you can continue to charge your devices.

Estream is easy to use. It’s lightweight and designed to fit in any size backpack. It is perfect for anyone who goes camping, backpacking, fishing, or kayaking — or anyone who has access to running water.

You can even use it as a backup power generator, as it can be charged through a regular power outlet.

According to the manufacturer, this is the first portable generator chargeable by water. It minimises the environmental impact of your energy consumption and allows you to take an active role in experiencing how energy is produced and used.
