    Very impressed and works well HOWEVER...

    • Written by from Boca Raton

    I love this product and use it whenever I can however it would not charge my second generation iPad but it doesn't bother me at all because this charger has an outlet which allows me to use the wall plug. Every now and then when I'm driving for a few hours I hear the fan but its not annoying to me because I hear computer fans all the time (Yes you can call me a computer geek :) ). I highly recommend this product if you want to charge your apple devices including your laptops while driving (two usb ports and one wall outlet).

    Fine Inverter, Mislabeled Uses in the Apple Store

    • Written by from Oakland

    The dual usb ports allow charging multi devices. Nice small form factor. Has a peak output of 150W with continuous of 120W.

    I bought it to use with my 85W Magsafe power adapter (both on planes and in the car) only to find that the inverter goes into protect mode everytime the magsafe tries to charge my 15" Macbook Pro. Looking more closely at the power requirements on the side of the magsafe adapter, it consumes 1.5A at 100-240V. At 115V, 1.5A is over the 150W peak of the inverter.

    I'm not sure if the adapter is pulling exactly 150W (1.5A at 100V) and the inverter is not able to put out its claimed peak, if the inflow rush characteristics of the adapter do not play nicely with the inverter, or if the adapter is actually pulling more than it claims - the bottom line, as a few others have pointed out, is this will not work with a 15" Macbook Pro.

    Won't run 85W power adaptor with MacBook Pro on planes

    • Written by from Laguna niguel

    I bought this to use my 15" 2011 Macbook Pro on flights. The draw of the 85W adaptor causes the inverter to surge and cycle on and off. The only way to use this onboard is to shut down completely (not standby) and then the draw is low enough to charge the computer. The only reason I gave it 2 starts is because you can charge your laptop while doing other things and get some use, and to be fair to the unit, the 85w adaptor has the same problem on planes with standard plugs.

    Runs well but the noise is annoying

    • Written by

    Powers good and quite longer than expected but the annoying noise is inescapable. Wish there was a sound-absorbent accessory that came along, even if for a higher price. Am yet to try it for a long flight but I know it will be fine with necessary amenities on plane.

    Great but noisy

    • Written by from La Mirada

    Charger works great, but the fan makes a loud sound and can get annoying.

    Power Good - Noise is not

    • Written by from PITTSBURGH

    I used this on a recent trip from Pittsburgh, PA to North Carolina - around 500 miles each way. I thought the power sustainability was very good. Had a MacBook Pro and a iPhone powered off it for almost 4 hours each trip. I would give the power side of my review 5 stars, but...

    I gave this product a 3 star rating because it is so noisy. The little fan has a very high pitched whining sound that drives you crazy. It was like a little jet engine whine and it's pretty loud, and it gets louder and a higher frequency with more of a demand on the unit. On a scale of 1-10, I would give the noise level a 3 or 4. Tried to hide the unit under the seat (without covering up the fan and air outlets) to escape the noise but you can't escape the sound.

    NOTE: I have tried several different power units over the years for a laptop on this very trip, this is the only one to provide enough power for such a long trip.
