There are days when I don't feel very smart.

When I got this unit I wanted to test it so I put the cigarette lighter plug on and plugged it into the car, plugged in my electric drill and then blew the fuse on the cigarette lighter socket.

Dummy, the lighter fuse is only 15 amps.

12 volt system at 15 amps, 12 x 15 = 180watts.

Even if you get a 50 amp fuse, 12 x 50 = 600 watts.

You can't fully use this.

This has to be connected directly to the battery for full use.

Connected directly to the battery works fine.

I give it three stars because it is typical quality of a product made in China--mediocre fit and finish, but it does work. The 2 AC outlets are closer together than a standard home socket, so that could cause problems if you try to plug in more than one wall wart. The outlets are not electrically grounded in any way, but this may true of all inverters since you're just taking DC +/and turning it into AC. There is a fuse soldered in place inside the case, so if for some reason that blows, you are out of luck unless you disassemble the case, desolder the blown fuse, and then resolver a new fuse in its place. To permanently install a fuse is just simply a poor design.

Overall then, it is okay, but not high quality. I thought about giving it 4 stars, the build quality and the oddly soldered fuse don't rate that in my book. See the video to understand about the replaceable fuse being permanently soldered in place.

Comes with cigar adapter and battery clamps. If you try to run over 500w with the cigar adapter you will blow a fuse since most vehicles are not rated to push out that much power. The only way to harness all 1000w is to hook it directly to your battery. Luckily since my car is an AMG my battery is giant and in the trunk. It has brackets so you can mount it and it will not move. Fan can get loud when you have a full load on. Things to remember when buying inverters.

1) Unplug when not in use. Wouldn't want to drain your battery overnight would you?

2) Check to see if the number is Peak or Constant wattage. You want a good constant.

3) Does it come with adapters you need? Cigar and Battery Clamps on this one.

4) Figure out what devices you want to power and check the wattage. Most devices tell you on the power pack or where the plug meets the device. Volts * Amps = Watts (my laptop power pack says 15v and 6amps, which means 90 watts)

5) It's better to buy double the wattage than what you figure you need. That way you aren't running it at it's max and burning the poor thing up. It's like you never being able to walk and always having sprinting everywhere. You'll get overheated and die. Why treat your inverter the same way?

With these 5 simple facts in mind. I hope you find the inverter that suits your needs!

This thing rocks, power went out I hooked my TV, laptop, and a couple lamps. Not quite as good a a generator, but in a pinch it will work.

We recently had a couple of minor tornadoes (if there is such a thing) race through North Atlanta, and it left us without power for 24-hours. It seemed like an eternity! I was very close to losing about $400 worth of food. I had an inverter that was rated at 275 watts, and tried to use it to power my freezer, but the initial power surge was too strong for too long for that inverter to handle it.

So I bought this inverter with hopes of not only being able to occasionally power my freezer, but also possibly my main fridge in the kitchen during an extended outage. It was not only able to do both, but both at the same time, which is amazing.

The freezer surges to 595W, and then after about 10 seconds drops to 125W where is just hums along. The refrigerator (25cu/ft Frigidaire) surges initially to 705W, and then after about 10 seconds drops to 205W continuous. I measured all of this using a Kill-A-Watt device.

I attached the freezer first and waited until it was only drawing 125W, then attached the fridge. I did this while the inverter was attached directly to my car battery with my car running. When I attached the fridge, the car sounded like it was going to stall, but it recovered and powered everything nicely.

In the event of an actual outage, I would probably just power each appliance individually for 30 minutes or so every 4 hours to keep things cold. I like knowing that this unit provides enough power to be able to handle either appliance, plus run an LCD TV, or some lights, etc.

Great inverter at a great price. If you're struggling with whether to buy a portable gas generator so that you're prepared for extended outages, this unit may prevent you from having to do that. It obviously won't do everything a generator can, but it's a lot cheaper, and can handle a lot of the basics.
