Xantrex Technologies 851-0178 XPower 175-Watt Micro Inverter

This thing is great. I used it to charge my laptop during my driving tour of D.C and Virginia. The fan noise is pretty low. When the music was on, it was very hard to hear the fan. Now I do not need carry different car chargers for different electronics any more.

I love gadgets! and this fits in with my lifestlye - RVing and being on the road.
It is great for running my laptop or charging my cell phone from the car!

This is a great product!! I purchased it for a long road trip, and was able to connect my X-Box to the power and play it on the trip! Definately recommend!

The product works great but the integrated cooling fan does make noise.

I am very pleased with this device. It allows me to use my laptop in the car. It is cheap to buy and small for travel. It does have a fan that makes noise, but I don't notice it when we are on the road, except when it is really cold outside (0F), when it whines for a bit, but then quiets down. It doesn't seem to interfere with the radio at all. It might not fit if your cigarette lighter is in a tight space, but it is fine on my car and a couple of rental cars that we used. It also worked in the plugs on American Airline's plane and was so easy to carry around! I have had other devices that were much bulkier and much more finicky about the power coming from our old car's battery. Bottom line: it is a price performer!
