this inverter does wonders. On a road trip this past summer, we drove from colorado all the way out to new york city, with many stops in between. The whole time, we had the tv and ps2 hooked up thru the inverter, and never did we have any problems. played constantly, it was great. DEFINITELY BUY IT if you are looking for a way for your kids to have fun in the car, or wherever. WORTH EVERY LAST PENNY!

I've owned several power inverters since I travel just about half of the week every week. I'm always working from the car. This is the best design I've seen so far for a power inverter. First, it has two inputs which is great. This way I can plug my laptop in and still be able to charge...a cell phone, or run another electronic device such as a portable DVD player. Another solid feature is the internal fan. This enables the unit to stay COOL. Other inverters I've had get so hot, you can barely touch them, which probably led to their malfunction in the first place. The other great feature is that the fuse for this device is EXTERNAL. Which means if it blows, its easy to replace. The last couple I've had have died and the fuse was the culprit, but since it was internal, it wasn't a simple fix. So thats a great design innovation on this one. Its also good that the power inverter comes with battery clips too..this way you can run it from the car lighter or the battery direct.

This is quite a nice unit for the money. Mine came with two cords - the cigarette lighter cord shown in the picture and a cord with alligator clips for connecting directly to the battery. It has an automatic short circuit detector and shutdown, a low battery voltage alarm and low voltage shutdown so you won't wreck your car battery, and automatic overload detection and shutdown. It has two outlets, a power switch, and an automotive type fuse, and an attractive metal case. Fairly impressive for the price.

I've only had this for a week so I can't speak about its reliability. I can confirm the fan noise, but I looked around a bit and that seems to be a common complaint about all the small inverters. The outlets have a ground pin, but users should not be deceived -- unless the unit itself is grounded (to a ground stake) the only ground is the chassis of the car. That's true for all of these units.

I was about to leave on a long road-trip. I liked the fact it had 2 plugs. But when it arrived and I opened it to check the manual, I discovered it requires a special connection to the car battery and was not recommended for most cars. I checked my car manual and discovered it could only handle 100 WATTS, so the purchase was totally useless. Please check your car manual before you purchase such an item. In fact, on the road trip, we burned out the car adapter by overloading it with 3 devices with standard car charger adapters. We also found that another AC adapter overheated, and would not supply sufficient power, unless the other devices were unplugged.

This powerful yet inexpensive inverter is very well made. With its 300 Watt continuous capability you can successfully power up various devices in your car. Modified sine wave is suitable since most of the modern electronic devices have switching supply anyway. Only direct electrical motor devices may have some problem with this.
The only drawback in my opinion is that the fan is always running what creates a certain sound. It would be essential to run the fan only in case of large power consumption and a significant temperature raise. The similar "smart fan" feature has been employed almost everywhere these days. The unneeded noise in the car caused by this fan is just a little annoyance and forced me to give this excellent unit only 4 stars.
Otherwise, this is a highly recommended buy.

I bought this a year back. It worked great for 1 year. I always use this whenever I go for trips. It still works without any problem except it recently started giving some noise(probably because of the fan).You can definetely get irritated unless you have music on with good volume.

My sister has asthma and needs to have a compressor /nebulizer machine in the car now. I wanted to buy the same machine she had in the house, pack it in a bag, with tubing and have ready in the car, with meds, for travel, around town, hotels.... this inverter is ready to go in the bag. its so great. what else can we plug in????
****** I plugged my ipod speakers and ipod in and drove around with new music,it was soo cool for a driving trip****this is a great gadjet, we are going to Newpor and buy fish on the docks and can plug the food saver into this and vacumn seal all the fish right there, another cool thing to use this for.***

We've had this unit for about a year, and we recently bought one for my wife's father. Good unit that we used during Hurricane Ike when we were without electricity for almost 3 weeks. We ran a light, small TV, and fan without a problem using the cigarette plug and starting the car (Tahoe) from time to time to recharge the battery. We also use it on roadtrips so kids can play DVDs and we can recharge phones that don't have car chargers. Some reviewers complained about fan noise-level, but we don't find that to be an issue. Our only issue was that the cigarette lighter plug is plastic and it broke one time when trying to remote it from car lighter. The screwoff tip broke part of the threaded plastic wall inside it. I superglued the plug together and haven't had an issue since. All in all, I think this unit is a good value.

This unit is perfect for my mobile ac power needs. Recharging my laptop while I drive is a snap. This is the answer for running my sons electronic video games that don't have the typical car charger. Unfortunatly, I do need to report that the cooling fan is a bit noisy. In most vehicles road noise drowns out the fan. But if you have a quite vehicle or you are stopped you can hear the fan clearly and it can be a bit irritating. Overall a great unit.

This Jensen JP30 300 Watt power inverter works great, I use it to run a laptop for GPS in my Semi. The truck has an idle feature that shuts the engine off after so many minutes idling time, I have a similar product rated at a higher wattage of a different brand name that would trip out on overload every time I would restart the truck and I would have to turn it off and back on, the Jensen just keeps putting power.
