The converter came in an antistatic-bag. Has one LED that turns on when is powered. The well assembled PCB has quite good soldering and features two Japanese capacitors. Both input and output voltages are stable. I love the versatility this boost converter offers me for DIY projects and for testing various electronic components. The built-in potentiometer allows you to regulate the voltage very precisely. You don't have to worry about the released heat because it develops zero temperature. It is awesomely small for it's capability and has four holes for mounting it. Note that it only raises voltage, not lowers it.

Livré dans du papier bulle pour le protéger. Je n'ai eu aucun soucis avec les soudures. Parfait pour un ventilo ! Je recommande ce produit.
