Rechargeable smartphone batteries powered by solar energy are very useful for easily charging these devices. However, new ideas are constantly emerging that aim to facilitate energy generation in situations where there is no access to the electrical grid. Estream is one such innovation, in this case harnessing hydroelectric power to charge mobile devices in situations such as camping or hiking.
Estream is a portable generator that uses the energy of any water current to generate electricity. This device is ideal for outdoor enthusiasts, as it allows you to charge your smartphone easily and efficiently. It's lightweight and portable, so it can be easily carried in a backpack, making it an essential tool for outdoor adventures.
How Does It Work?
Estream converts any water current into stored energy, allowing you to charge any USB-enabled device, such as smartphones or GoPro cameras. To use it, simply unfold its propellers, lock them in place, and submerge the device in the water. Once submerged, the current causes the propellers to spin, which activates the internal hydroelectric generator. Even in slow currents or behind a boat or kayak, Estream continues to operate flawlessly.
Loading capacity
With a power output of between 2,5W and 5W, Estream can charge its internal 6.400 mAh battery in approximately 4,5 hours . This charging capacity is sufficient to power up to three mobile devices, such as smartphones, a GoPro, or even a tablet. Being a rechargeable and portable device, if you have access to a water source, you can continue charging your devices throughout your use.
Its modular design not only makes it portable, but also adaptable for different applications. You can use Estream to keep a device charged while in the water, making it extremely versatile in multiple situations.
Other features and benefits
- Estream stands out for its portability, weighing only 800 grams, allowing it to be carried comfortably in backpacks, ideal for hikers.
- You can charge USB devices wherever there is running water, no matter the flow rate.
- The modular design allows it to be expanded according to load needs, improving its versatility.
This portable generator aims not only to make life easier for adventurers but also to bring electricity to countries and regions where access to the power grid is limited. Estream will help provide clean and affordable energy to remote communities.
The project has already garnered significant support in its crowdfunding campaign, raising over $122.245 of its original $80.000 goal on Kickstarter , demonstrating the strong interest in devices that combine sustainability and practicality.
This portable hydro generator is definitely one of the best options for those who want to avoid relying on solar batteries or power outlets during their outdoor activities.
