Customer Rating: - Great product
I am satisfied with the XANTREX, I used it and it worked great.
I didn't give it 5 stars because I am not sure how accurate is it's battery low - warning system. I had only one laptop, with an external hard drive connected and at times it started beepingm, even if I was driving. I had to turn it off, run on battery for a while, then start it again.

Customer Rating: - Converter review
Been using this converter for close to 2 years now. I've used it for powering my laptop charger and cell phone charger with no problems. It's small and can be stored under the car seat. Excellent value!

Customer Rating: - Powerful
This inverters is exactly what we were looking for. It has plenty of power (we were running a couple of laptop, phone charges, and ipods simultaneously on our last road trip), is very straight forward to use, and even gives you the option to hook it up to the battery directly should you ever want to use it outside the car. I haven't had it long enough to give an sort of review on reliability, but it certainly seems solid.
