Xantrex Technologies 851-0400 XPower Plus 400-Watt Inverter

I got the Xantrex for a family trip to Virginia, and it worked exactly as advertised. The kids ran two laptops off of it for the entire trip, and never had a problem. The cooling fan did come on once for a few minutes, and, as others have noted, the fan is audible if you listen for it, but no louder than the road noise and far from problematic. Besides, it only happened once in about 36 hours of use, and then only for about three minutes. The unit is really well made and well worth the money.

This 400 watter suits me well with its dual 3-prong AC outlets, fan equipped, aluminum body, and reasonable price.

I purchased this for an RV trip. We didn't want to run the loud generator while we were driving, but did want access to some electronics like TV and video games. The unit performed great. It has a toggle switch for on/off as well as an LED light to indicate its on. I don't understand the technical details of how this works, but every so often it would run h-o-t, so keep it somewhere well ventilated and away from hands/feet.

This little device can replace all of those specialty adapters for your portable game machines, cell phones, etc. When taking a trip recently my son was able to pacify himself with his laptop and gameboy while staying connected to this handly little device. With two connections you can have more than one device connected simultaneously.

It works exactly as advertised. This is a little know secret and if more widely know would replace all of those other mobile adapters that individually cost as much as this device alone.

It is easy to install, not very large and very little noise. The only noticeable noise was when it heated up there was some fan noise but not loud enough to be disturbing.

Good, solid charger. Sometimes makes some fan noise, if my laptop starts pulling hard. No real complaints.
