    They work as expected. Easy to fine-tune the output voltage. In the enclosed figure, the boost converter lies inside the red heat shrink sleeve, and I can now get 9VCD out from the 5V USB mobile charger.

    Très beau module step up de faible puissance. idéal a utiliser avec une alimentation 12v livré en sachet antistatique ce qui est appréciable

    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.
