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.

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....
Suggestion:
None.

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.
Suggestion:
Nichts

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.
Suggestion:
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.
Suggestion:
Crank slips from motor.


Long charge time.

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.
Suggestion:
Some devices may not correctly charge with the manual crack or it will take some time to charge the device.

Looks of a good quality. As described. I tried to charge a cellphone with it. Iphone 7 does not charge at all. Samsung note 5 is able to charge, but you have to rotate with a constant fast pace.
