    ენერგიის გარდამქვნელი
    Color:Black
    Pros:
    ეს გახლავთ ენერგიის გარდამქვნელი,
    მისი საშუალებით შეგიძიათ ხელის მარტივი მოძრაობით ძალა გადრდაქმვნათ ელექტრო ენერგიად რომელითაც შეგიძიათ USB მოწყობილობების დამუხტვა, როგორებიცაა: სმარტფონი, USB ნათურა, პორტატული დამტენი, ვიდეო კამერა, და ასე შემდეგ,
    მაქსიმალური გამომავალი ძაბვა 5.5V გახლავთ:
    მისი მოქმედებაში მოყვანისთანავე მასში ჩაყენებული წითელი ლედ ნათურა იწყებს ნათებას რაც იმის მიმაNიშნებელია რომ ძალა გარდაიქმნება.....
    გამოადგებათ მათ ვისაც ხშირად უწევს მოგზაურობა, გადაუდებელი სიტვაციებში....
    Cons:
    None.

    Ganz Ok
    Color:Black
    Pros:
    Ja, was soll man sagen, es dauert natürlich ewig um damit ein Smartphone aufzuladen, aber dafür ist es ja nicht gedacht. Es soll einem eher im Notfall ohne Strom helfen um ein bißchen Saft ins Gerät zu bekommen und dafür ist es super geeignet. Anbei sind 3 Fotos und ein Video vom meinem Youtube Kanal, wo ihr viele weitere Videos zu Gearbest Produkten findet.
    Cons:
    Nichts

    Color:Black
    Pros:
    The product would definitely come in handy in an emergency . I am not sure it has practical everyday applications. The charge is not efficient and it takes about 20 minutes of cranking for a percent change on a stylo lg phone. But like i said, in an emergency that one percent will save your life. Worth it for the price.
    Cons:
    Crank slips from motor.


    Long charge time.

    Good product
    Color:Black
    Pros:
    The product is easy to use. Plug in a USB cable with a micro-usb or type C at the othe end and start making energy for your phone or tablet in order to charge it. When the emergency charger gives energy, a red light will be turned on.
    Cons:
    It makes a lot of noise and it doesn't work all the time. Maybe I'm doing something wrong.
