It is a micro-USB charger. Your device is Samsung and it looks like a "original charger" out. However, that included me, charger a cargo capacity of 1.3A. This only 0.7A. So it takes almost twice as long to charge the 2000 mAh battery of Samsung Galaxy Beam.
Otherwise, the processing is fine. Both the power supply and the Micro-USB connectors are well made and do not wobble.
