    Caricatore Manuale USB di emergenza - VERDE
    Il dispositivo è abbastanza robusto e semplice da usare.Ho girato la manovella per più di 5 minuti consecutivi ed effettivamente la corrente viene erogata perchè sul display del cellulare compare la scritta "in carica tramite CA". Però la percentuale di ricarica della batteria non è mai salita neanche di un solo punto.L'ho provato invece su uno smartband e su uno smartwatch ed entrambi si sono caricati bene anche abbastanza velocemente.Questo probabilmente è dipeso dalla notevole e diversa capacità che ha la batteria del cellulare rispetto a quelle degli altri due device.Perciò in conclusione direi che il dispositivo funziona.Sono soddisfatto.Gearbest buon venditore.

    NO Hand Manual USB Emergency Charger for Mobile Phone
    I really enjoy using NO Hand Manual USB Emergency Charger for my Mobile Phone.I was always worry about the charge dropping each time I call my family in remote areas where no electricity does not at all.I find it easy now after I have recieved my item .It takes few minutes to charge my mobile or tablet using my hand.
    It would be much perfect if it included USB cable and adapters.

    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.
    Crank slips from motor. Long charge time.

    Manual Charger is Great
    It's small and compact and it was made for emergency charging. It's light weight and can easily fit into your pocket or bag while hiking. Easy to use. I would recommend it to others.
    Some devices may not correctly charge with the manual crack or it will take some time to charge the device.

    Good product
    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.
    It makes a lot of noise and it doesn't work all the time. Maybe I'm doing something wrong.

    Emergency USB Hand-cranking Manual Dynamo Charger
    - easy of use - working as expected - useful in case of emergency - acceptable build quality - good price
    - cheap and weak looking plastic construction, can easily break the crank or housing - have to roll a lot for a perceptible charge - the unstable charging voltage not suitable for all devices
