After about 5 months, one of them stopped working.

This thing blew fuses in both of my cars when I turned it on, even though there was no load on the inverter.

I has been on ever since I put it in my semi. I have a laptop, a printer, and four chargers for cordless devices hooked to it on a power strip. The fan will come on if I'm watching a movie on the laptop but that is the only time I have ever heard the fan come on. It is exposed to temps from below 0 to 80+ and hasn't complained yet.

I just opened the package and haven't used this thing yet - so I can't comment on functionality - but I wanted to let others know that this unit DOES come with a cigarette lighter plug (as well as a set of alligator clips) that you can attach to the screw posts.

I wasted a couple bucks on a separate cigarette lighter plug when I ordered because the product information says nothing about coming with the cigarette lighter plug.

Oh - There is also a sticker on the cigarette lighter cable warning not to draw more than 150 watts when using it plugged into a lighter socket (use the alligator clips or your own custom wires to connect straight to the battery for full power)

The power inverter works great. I used it on a 5000 mile road trip powering a PS3 and iPhone and another cell phone along the way, in addition to other small electronics. To get the most power out of the unit, you need to hard wire it directly to the battery. I mounted it under the passenger seat and ran some 8 gauge wire. Very easy installation. I looked at several inverters before purchasing this one. The usb connection was what sold me on the unit. I now have an easy way to charge my iPhone without having to buy a car charger or taking up one of the regular power outlet slots. Well worth the money. The only thing to note for Amazon is that the product listing advertises that it comes with a carry case. It does not. No problem for me because I don't really care, but it may matter to you. I believe the CPI 475 does include the case.

Power ratings are grossly over-stated. I have owned this product for about 1 year. It has worked great for powering my laptop while in the car. I have not been able to get it to supply power any greater than 100W without it shutting off however. With the inverter connected directly to clean battery terminals with the included battery clamps, vehicle running (14+ volts at clamps), I have unsuccessfully tried powering two different TV's rated at 140W. In both instances the inverter shut off when the TV's where powered on. I next tried turning on a 150W halogen flood lamp. The inverter shut down before the lamp lit. This inverter is rated at 400W RMS/800W peak. It should be able to supply these loads without any issues. Keep in mind I tried these loads with the inverter connected directly to my (dual) truck battery, engine running. The test where run on multiple occasions. There was no lack of supply current/voltage.
Upgraded from 1 to 3 stars: I have since "hardwired" the inverter to my vehicle battery with an Anderson Power Pole 50amp connector in between. With this configuration I have been able to get a full 400 watts reliably from it. I have been running this setup for about 2 years now. I use it about an hour continuous once a month.
Updated: have been running for about 4 years now. It works fairly well. As mentioned above I had to "hardwire" it to get the rated capacity. Even using the included alligator clips connected to clean battery terminals did not give me a good enough connection to supply the full rating. I often run a 300 W halogen lamp as well as things liek a laptop and mobile battery chargers.

I just received my Cobra CPI 480 400-Watt unit today. This is a "Modified" Sine Wave output inverter as opposed to "Pure" Sine Wave needed by some of today's high efficiency electronics.

The lighter cable option allows taking this unit in a different vehicle. My unit came with both lighter plug and jumper cable type power connectors. The lighter plug has a 15A fuse in the tip, limiting output to a continuous 165W (hence the 150W mentioned in the manual). Higher power levels will require direct connection to the battery terminals, or the fuse will blow.

The lighter plug, as noted in other reviews has trouble staying electrically connected in my Cadillac Seville lighter socket, but doesn't fall out. The rear passenger lighter sockets have the same mechanical connection issue.

[The following comments were made from a unit sent back for repair. Addendum comments made against a new unit are at the bottom of this review, and new scope image replaces the old one in customer images.]

With the unit connected to a car battery with the engine running for high power checking, a Hoover 110V hand vacuum runs just fine. I grabbed a 500W halogen contractors light to see what happens on overload. The lamp starts to light and about 200mS later (~1/5 sec) the units starts shrieking and turns off output. [This behavior changed in the new unit (below) which now powers the 500W lamp for a minute] This unit does not recover from this condition automatically. The front panel switch must be turned off, then back on for the unit to recover. This also implies that any motor load with high startup currents has to be substantially started in 200mS or the overload condition will trip on this inverter.
