You can use a power bank to charge your mobile phone during short-distance outdoor trips, but power banks for long-distance outdoor trips cannot continuously provide power, and they themselves require external power sources to maintain. The most effective solutions are derived from natures endless natural resources, such as solar energy, water power and wind power.
Nils Feber, a designer from the University of Arts in Lausanne, Switzerland, has developed a portable wind power device. This device has a simple structure and can use wind power to generate electricity when deployed. After folding, it is only about the size of a crutch, easy to carry and does not take up space
The device is composed of two parts: canvas and a micro-generator. It is made of carbon fiber, so it is very light. When the wind blows on the canvas, the generator can run to provide power for mobile devices such as mobile phones. It does not have a power storage function and requires a mobile power source to store power, which is sufficient for emergencies in the field.
Nils Febers portable micro-wind power generation device has been well received by outdoor sports enthusiasts because the device is portable and can provide stable power output when the wind is weak. Official website: http://nilsferber.de/
