The powerful power supply unit does not heat at all. My received model is 100 ~ 240 volts / 2500 mA. The connectors are molded and seem quite solid. The adapter is plug-n-play for Windows recent. In the other mini cd, backup software "PCClone EX Lite" is provided. This comprehensive kit contains all the accessories necessary for immediate use unpacking. Yet this generic adapter costs me 2-3 times cheaper than competing products.
