CoolerMaster offers not only ATX power supplies for PCs, but has morerecently, universal power supplies for notebooks in the program untilnow, the USNA 95 is particularly compact specimen with 95 watts, thestrongest model.
With theUSNA 120 Cooler Master has now introduced a newer and larger model,the power supply provides up to 120 watts and can be connected via asuitable adapter to virtually any laptop that works with 120 watts ofpower.
The USNA120 like all notebook power supplies, a small black box with thedimensions 65 x 21 x 156 mm, and thus quite compact, but not ascompact as the USNA 95th At the top there is an LED that glows greenwhen in use. The connecting cable of the USNA 120 are all enforceableon the one hand, a normal power cord is connected to the other sideof the connecting cable for the laptop.
Sincethe several notebooks entire have various connectors, located on thepower supply, a set of 10 unlike adapters to same notebooks fromAcer, , DELL, IBM, BenQ, Sony, Compaq, Gateway, MSI and Samsung fit,of course, important that all notebook brands can be operated withthe adapters.
Aspecial feature of the USNA 120 are the two USB ports providing thepower supply, these two USB connectors can be used as a USB chargeror as a power source for equipment purchased through the USB power,the two USB ports can be loaded with up to 2 A and work in parallelwith the 19V connection for the laptop. It is therefore possible tooperate the notebook and simultaneously charge the two USB portssmartphones, tablets, cameras or other devices, this saves thelugging of USB chargers, if you have laptop power supply has itanyway.
Anotheradvantage is that the two USB ports do not "data connections"are some devices load data to a USB port that is automatically slowerthan in pure USB power ports of chargers, so that the connection tothe USNA 120 compared to the load on the laptop can even accompany aspeed advantage. Cooler Master has advantages in speed of up to 30 to50%, this greatly depends on the device you want to load.
