    Está tudo certo com esse produto. Vieram os cinco em uma embalagem antiestática muito bem embalado. O conversor funciona muito bem para a aplicação. Recomendo.

    I used these to make a step-up regulator built into my goggle battery cord. This way the goggle always think the battery is full. I added a little voltage display to the Voltage in so I can see when my battery is low.

    Повышающий преобразователь напряжения. Использую такие для питания устройств с напряжением 5В или 9В от 18650 аккумуляторов. Качество сборки хорошее. Флюс отмыт. Количество соответствует

    For the price they work ok. Keep an eye on the input voltage and power draw. I blew up 2 units by drawing about 1.8A for about 30s. But for low current applications they work ok

    Lo utilizzo per rimpiazzare la batteria da 9V di alcuni strumenti con una batteria Li-Ion da 3,7V. Perfetto se abbinato con un caricabatteria con protezione da scarica eccessiva. Ottimo!
