    Can be used as a emergency source of energy. But not as a main one.

    I made some measurements of this device. And wrote a detailed review of it at mysku.ru/blog/china-stores/60323.html Main idea: the device does its job. Notwithstanding the fact that it has plastic gears and not so good handle, it can produce energy with all declared voltages. One man can easily charge a phone for a small call in couple of minutes. So, according with my investigation, the efficiency of this device is about 0.22 The generator can be used as a motor. Conclusion: it cost its price, especially

    Nice useful novelty

    Nice workmanship. Very smooth cranking and gears appear to be well sealed from dirt/dust - hopefully metal. I tried this on the 5V USB output - you must remember to have the voltage selector switch at 5V, or you may damage the devise you're powering. About 60 rpm was required under a load of about 1.5A. Pros: Well built, using brushed motor - size 540? Cons: no safety on USB output - you better remember to set the selector switch to 5V, and it would have been nice if the USB ports were mounted right

    Ce générateur semble assez fragile et n'est sûrement pas pour un usage intensif. Il faut bien faire attention à le régler sur5V en cas d'utilisation de la sortie USB. Sortie qui ne fonctionne pas avec tout les appareils USB. Mais en réglant le générateur en sortie 12V ou 15V et en passant par un régulateur externe, comme celui trouvé dans les chargeurs de voitures par exemple (voir photo) ça fonctionne impec. Attention à ne pas dépasser l'intensité max qui est donné pour 4A mais qui

    semble un peu fragile et n'est certainement pas pour une utilisation intensive. Mais très utile ponctuellement lors d'une sortie ou en camping, surtout en cas d’intempéries car dispo jour et nuit contrairement aux panneaux solaires. ne recharge pas tout les appareils directement branchés sur l'USB, mais à travers un régulateur externe, comme ceux que l'on trouve dans les chargeurs de voiture, c'est parfait. (voir photo). Attention à bien positionner le sélecteur de tension sur 5V en cas d'utilisation

    It really gets the job done, feels good in the hand and it isn´t hard to crank, despite it arrived a bit late worked fine. I like it P.S. you would spend lots of time trying to charge your fone, this is for emergencies.

    Генератор 20 Вт

    Ручной привод. Прочный металлический корпус. При желании можно запитать всё что питается от 5-24 вольт, и можно соорудить привод от ветра или течения. Компактный, но великоват для рюкзака в походе. А вот на даче выручает часто. Качественная и полезная вещь.

    Чтобы поддерживать нужное напряжение нужно крутить ручку очень быстро и интенсивно чем больше ампер нагрузка у подключенного потребителя тем крутить становится тяжелее и ток бльше 1Ah поддерживать не получается вырабатывать 12V ваще трудно замучаешься крутить руку можно накачать
