Very Good.

buen producto lo recomiendo

very good product it's working ok!

Product as described..Tiny booster module. does it's job perfectly. when differences between input and output voltage is greater than 10V the module becomes very hot. Used it inside a mosquito killer racket for regulated 6V power supply using a 5 V input from powerbank.

Είναι το δεύτερο που παιρνω. Το πρώτο που πήρα το έκαψα. προσπαθησα να κάνω step down. Αλλά είναι μόνο για step up.

Super goods, everything was okay, safely packed, fast shipping, highly recommended. With best regards from Germany.

Great price

Good product, works as described

molto buoni, avrei dato 5 stelle ma dei 3 che ho ordinato 1 è arrivato danneggiato, è stata sicuramente colpa di qualche corriere poco attento,ma con i 2 restanti ho trasformato una ventola con il molex rotto in una usb. adesso la userò per togliere il fumo mentre saldo. ovviamente comprerò di nuovo questo prodotto per progetti futuri
