This product works great, I have a microwave, flatscreen tv, and a toaster i hook up to it and there is no problems. One thing I wish would have been mentioned somewhere is that you need to purchase a 150 amp inline fuse to put in the power wire from the battery to the inverter. So plan on getting one of those and have it ready so you can install it. I didnt know about it and spent some time in North Dakota trying to find one. Enjoy.

I bought this unit to create a back up system for my home hot water steam heat radiator system. We are experiencing more and more power outages during our harsh winter months, and although we have natural gas and the pilot stays on during an electrical outage, there is a small gas valve that needs 25 volts of power to open to allow the gas to be lite by the pilot. There is a standard 120 line going to a small transformer that reduces the voltage on the furnance and without power no heat. BRRRRRRR lol, anyway talked with our plumber when he serviced the unit this year and we came up with the idea of an inverter to do the job. Amazon delivered the unit in 3 days, came well packed, and didn't take long to read the directions and figure out how to operate it. I have 3 vechicles and 2 extra batterys so I decided this was a better way to go than a generator, didnt want the smell, gasoline, or fumes. Have small trickle charger for the battery and when we hear a storm is on the way we will charge up the battery to be sure we have full charge, have operated the furnance unit for 30 minutes and IT WORKS OFF THE INVERTER MISSION ACCOMPLISHED, and the draw was so low the battery didnt lose any power during the 30 minute test. Also tested a house lamp with a 100 watt bulb and it ran for 30 minutes also with almost no lost of battery power. The unit looks good, is relatively silent, and does what it promises to do. I LOVE IT. My only comment is you need to be aware that it does not come with any cables to hook up to the battery, I split a pair of heavy duty jumper cables that I had laying around and use them. Short of that it is well worth the money, and I look forward to using the unit on remote job sites to power my electrical tools during the spring and summer. Again an excellent product.

The inverter is working for me exactly as described and as I hoped. I drive a truck and have it installed to replace an older, smaller model. I run a number of things including my laptop, external speakers, printer, TV and a coffee pot. The low input warning works great, and will shut down the inverter if necessary. I will be adding things soon, such as a microwave.
The meter is a great feature which lets me see how much power is being drawn by each device attached as well as the input voltage.
I highly recommend this inverter.

I use this in the trunk of my 1982 Mercedes to power an immersion heater for a vegetable oil tank. I heat approximately 15 gallons of vegetable oil, which pretty much drains the deep cycle battery that is dedicated to the inverter. In the cold months, this inverter is handling 1.2 kW for about an hour everyday, and I haven't had a single problem.

I have purchased 25 of these for one purpose: running laser printers in our sales team's vans. As you may or may not know, laser printers draw quite a few watts when they are warming up, so I wasn't even sure if these would do the trick. They always say you should have a power inverter with quite a few more watts available than you intend to use, so that's what I did.
This thing powers those laser printers without even breaking a sweat. I've had other inverters that are of much lower quality, and even a moderate draw on them causes the fans to kick into high gear, making it sound like a vacuum cleaner is running.
When it comes to electronics like this, my first impression is how heavy they are. Heavier (generally) = better quality... and these weigh a few pounds, nice and sturdy.

UPDATE: I had problems with 2 of the 25 units and Cobra sent out replacements ASAP, no questions asked. Excellent support.
