The latest Rompower technologies in power conversion reduce the size of the 65 W laptop adapter to the size of an AC power plug
The ac/dc adapter technology has evolved over the last years and presently the technologies developed by Rompower Energy Systems Inc., increase the efficiency from 88% to 94%, the highest in its class. This increase in efficiency decreases the power dissipation by more than 50% making the adapter to run much cooler. Lower heat dissipation allowed Rompower engineers to reduce the size of a 65W laptop adapter to a tiny volume of 2.3 inc3 (38.5cm3) comparable with the AC power plug, while eliminating the bulky AC cable.
