FSB NB L90If you travel a lot having one always in your notebook travel bag can be of great benefit as doing this will eliminate you forgetting to take your original one along. I remember this happening to me last year when traveling to Las Vegas for CES. To combat that dilemma FSP Group (Fortron/Source) have produced the NB L90 laptop power adapter. The L90 is capable of producing a whooping 90 watts of power, or 4.74A at 19 volts (+/-1V), which is enough to power most laptops up to about 17”. We will be testing this new adapter on my Sony notebook to see if it is worthy of your hard earned dollar.

Introduction to the FSP NB L90 Notebook Adapter

Universal power adapters are a godsend for many of us. Reason being is that many of us use our laptops in many different locations throughout the house. In my case I take my laptop from the living room, to the home office, to the bedroom. In two of the those three locations the wall outlet is located behind some heavy furniture, so having multiple power adapters that can be static fixtures really comes in handy.

Closer look

The L90 is a very slender power adapter and looks as though it shouldn't take up very much space even in the smaller laptop cases. According to FSP the L90 weighs less than a pound, so there isn’t much weight to it if you need to carry the unit from one location to another.

At the higher level of output the L90 supports a maximum of 90 watts. To sum it up the L90 can supply power to any laptop or similar device just as long as it does not exceed the 4.74 ampere that it's rated for. Within the power range the L90 offers all the standard power protections to keep and overload or short circuit from happening.

Included in the package are a total of nine different tips, each being color coded. FSP includes a small list of which color should work with what manufacturer. Each tip consist of +/- poles and are notched on one side to prevent incidental polarity mismatch once inserted into the power adapter socket.

As part of the accessories that comes packaged with the L90 is a nice little carrying bag to hold all the little pieces together so you don't misplace anything.


Testing

Testing for an A/C adapter is pretty simple and that is plugging it into what it is meant to power and go on from there. The guinea pig was my personal Sony F series laptop that requires 19.5v. Just right for the 18-20 volt range of the L90 adapter. After testing with this laptop we found that it worked perfect. We also decided to use my wife’s little Lenovo S10 netbook and once again no issues whatsoever. Thanks to the 87% efficiency the adapter never got all that warm.

Editor's Note: While I know many of our readers are quite tech savvy, I'd like to point out a small bit of info not everyone may be aware of. The technical specs indicate this power adapter being capable of 90W max, which is calculated by multiplying Voltage by Amperage that the unit can produce, in this case 19V and 4.74A. So if you have a laptop like the ASUS G73Jh that has an i7-720QM and HD5870M, but requires the 19.5V like Tony's, under load your system might draw every bit of the 7.7A that it's original power adapter can supply. If so that would equate to 150W, which is almost 1.75X as much as this unit can supply ;)  

 

Conclusion

Despite the small foot print of the L90 adapter we found that it was very capable of powering systems from a larger than average laptop, down to the smaller netbook units. The L90's small size and light weight making it easy to carry around in your laptop bag or carry-on luggage. The adapter is only 16mm thick and weighs a little more than half a pound.

We would love to have a USB port on an adapter like this for charging things like cell phones and media players. Even still, a device like the L90 is a must have in our books.
