Product Description
Amazon.com Product Description
This inverter provides household power on the go. It converts battery power to 120 V AC household power, allowing you to power up office equipment and household appliances from your vehicle. This unit is ideal for such appliances as microwave ovens (1000 watts or less), coffeemakers, laptops, TVs, video game consoles, CD and DVD players, cell phone chargers, and more.

How The Cobra Power Inverter Works
The Cobra power inverter is an electronic product that has been designed and built to take low-voltage DC (Direct Current) power from your automobile or other low-voltage power supplies and convert it to standard 115 volt AC (Alternating Current) power like the current you have in your home. This conversion process thereby allows you to use many of your household appliances and electronic products in automobiles, RVs, boats, tractors, trucks, and virtually anywhere else.
Cobra 1500 Watt Output Waveform
Some very sensitive electronic equipment might not operate satisfactorily on "square wave" or "modified sine wave" power. The output waveform of the Cobra Inverter is a "square wave" or "modified sine wave." It is a stepped waveform designed to have characteristics similar to the sine wave shape of utility power. A waveform of this nature is suitable for most AC loads, including linear and switching power suppliers used in electronic equipment, transformers, and motors.
AC receptacles
With three ground AC receptacles, you can connect and power multiple devices at once.
USB Output
The 5-Volt USB output allows charging and operation of modern portable devices, such as iPods, BlackBerrys, and cell phones.
Remote On/Off Switch Capable
An optional Remote On/Off Switch can be connected to the Remote Jack, allowing you to turn the Cobra power inverter on or off from a convenient location when the inverter is installed out of reach.
Safety Features
The CPI 1575 will notify you with a flashing meter and alarm sound when there is a power problem, and will shut down for protection in the following situations:
- Current Overload Protection--If the inverter is overloaded, it will shut down to protect itself.
- Short Circuit Protection--If the AC output of the inverter is short-circuited for one second or more, it will shut down to protect itself.
- Low Voltage Protection--If the input voltage drops to 10.0V or less, the inverter will shut down to protect itself.
- High Voltage Protection--If the DC input voltage rises above 15.0V, the inverter will shut down to protect itself.
- Over Temperature Protection--If the internal temperature rises to 40 degrees C (104 degrees F), the inverter will shut down to protect itself.

This review is in response to some comments regarding wire and fuse size selections for this inverter and others like it.
In response to other review quoting a table from the National Electric Code (NEC). While the table that was posted is correct for 115VAC (household voltage) is does not translate directly to 12VDC (automotive voltage). When dealing with a 12 volt system there is less concern with wires overheating, at least in the way that the NEC considers it, and far more concern with voltage drop. When running wiring a reasonable distance (a couple hundred feet or so) there is little concern with voltage drop with AC power. But when dealing with DC, simply increasing your wiring distance 5-10' can have a drastic effect on voltage drop. That is why this inverter should be wired with, at the very least, #4 wire and really should be installed with #2 or thicker, especially if you need to run wire 15 or 20 feet or more.
The purpose of a fuse in a DC system is to protect the rest of your electrical system in the event of a short. That is why you always want to install your fuse as close to the battery as possible (no more then 3' if you can help it). As far as the amperage goes, there is a really good quick reference chart for automotive wire size that can be found at Tessco's web site here:[Turns out I can't link to an outside page so I'll paste the contents of the table at the bottom]. But to boil it down, you can safely fuse a 12VDC circuit at 150, or 200 amps, or more on #4, #2 or #0 wire.
Now this unit at full load is something like 85% efficient. So if you do the math -- 1500 Watts / 12 Volts / .85 efficiency = ~147 amps, A 150 AMP FUSE IS REQUIRED. If you take peak power into account you would need to double that to a 300 amp fuse, but because the inverter cannot run at peak power for more then a moment, a slow-blow 150amp fuse may work just fine, or perhaps you could step up a 200amp. I wouldn't go all the way to a 300 amp fuse unless you really found that you needed it and had the inverted is wired in such a way that it could handle that level current (read: installed using very heavy gauge wire). Now if your vehicle is running while your inverter is working the amperage will be a little lower because your dealing with 14.4 VDC rather then 12 volts (watts = volts x amps -or- amps = watts / volts). But at the very least, a 150 amp ANL fuse is very good idea and not at all over sized.
Just a FYI on fuses, most car stereos are installed with AGU style fuses, but they only go up to 100 amps.
You will need an ANL style fuse to get one rated at 150 amps or more. See these links for examples:

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.

Other reviewers don't seem to have had the problem I did, so this might be a good product but I must tell you my experience with it. I am very familiar with inverters and how to hook them up having lived off of solar power now for over ten years. When I first set up this inverter, the input voltage showed 12.3 volts, the same as my battery voltage but undr a 110 watt load the output wattage meter showed 0 (zero) watts. What I had plugged into the inverter was working fine (a small TV), so I assumed this meter was just broken. If that was all that was wrong I could have lived with it. The next morning I turned it on, turned on the same TV and within 20 minutes the picture on my TV slowly shrank down to a pinpoint and then shut off. There were no low voltage warning sounds. I checked my battery level and it was at 12.2 volts, the same 12.2 volts showed on the input meter on the inverter, output still showed zero, as it always did. I checked the output at all three of the outlets on the inverter and they showed zero. I turned the inverter off and then back on with the voltage meter still in one of the outlets and watched my meter go from 119 volts down to 30 volts, up to 80 volts and then back to zero. The whole time there were no warning sounds coming from the inverter. This fluctuation could very easily damage anything that was plugged into the inverter!!!!
The good news, Amazon's return system is very easy, didn't cost a penny to return it and I got a refund quickly. I thought of getting a replacement instead of a refund because of all the good reviews but decided not to press my luck, no equipment was damaged this time but why risk it again. If I could rate Amazon I would give them five stars but the inverter gets zero xtars since it didn't function as advertised, went dead under much lower load than it is rated for.
