The power brick is small measuring only 4.1 inches long, 2.4 inches wide and a slim 0.7 inches thick. It is not much bigger than a 2.5 inch hard drive, which makes it easily portable for all of your power needs. The USNA95 is rated for 95 watts output and Cooler Master states that it has up to a 90% efficiency, which means less wasted power keeping your energy bills down when using it. The main thing that really sets this power adapter apart from the competition though, is the ability to charge other devices while charging your notebook. That’s right - Cooler Master has included a USB charging port so you can keep your music players, mobile phones, and PDA’s fully charged at the same time with only one power adapter. This means less clutter to carry around when traveling, by not having to carry a charger for each device you have. The USB port provides a whopping 1 amp and can charge devices up to 30% faster than a standard USB port on a computer. The charging is independent as well, meaning you can use it just to charge a USB device without having to have a computer connected to it or powered on as well.
There are a total of nine power tips included to charge your notebook, laptop or even netbook. The manufacturers include ACER, ASUS, HP, COMPAQ, BENQ, IBM, LENOVO, SONY, DELL, SAMSUNG, GATEWAY, TOSHIBA, NEC, and FUJITSU. To use, just select the correct tip for your system and plug it into the power tip cord, ensuring the flat sides match up. Then you are ready to use your Cooler Master USNA95 for all of your portable power needs.
To keep everything together for travel, Cooler Master has included a tote bag. Everything fits nice and snug inside and there is even room for you to place your small portable devices as well, keeping everything together and safe from loss.
When in operation there is an LED that signals what mode the power brick is in. When in normal use for powering your computer the LED is a green color. This verifies that the power adapter is on and providing power ready to charge. When you plug in a USB device to the charger, the status LED changes to red, notifying you that the USB device is in fact successfully charging. The LED will remain red until the USB device is removed.
Here are two shots showing you how easy it is to charge your devices. Notice with very little clutter I am able to charge my Samsung N130 netbook and my Motorola Droid phone at the same time. This keeps me productive without having to carry multiple chargers. You can see in the second picture that the mobile phone is still charging even when my netbook is powered off keeping full batteries on both.
Now that everything is set up I am ready to start putting this baby to the test.
