Huntkey has announced its ES 90 W Ultra Edition notebook adapter. The previous model, simply called the ES 90 W Notebook Adapter, was 2 percent less efficient. The Ultra Edition is an impressive 89 percent efficient. It also has a 33 percent lower standby consumption at just 0.2 W. Its input voltages can range between 100 V and 240 V, at either 50 or 60 Hz; it puts out 90 W at between 18.5 V and 20 V. It should also work with most standard notebooks.
Beyond the small improvements in energy efficiency, the unit is also more efficient in size, being 21.9 percent smaller.
It also carries all the standard safety features we can expect from these power supplies including CB, CE, CCC, FCC, UL and RCM.
