This is a simple form-factor converter from a round to flat socket. It doesn't adjust/convert the power or doing anything smart, and this is not required from it. It does the job well and looks like a solid and reliable product with nothing to fail inside. I've managed to reuse a number of laptop chargers with a round plug for the Carbon laptop and I wish there were more of these on the market helping to minimize the waste of resources due to incompatible chargers.
